Objectives:  The objective of this study was to assess the oral Candida albicans colonization ( OCAC)  in a cluster of teenagers and young adults while being treated with a fixed orthodontic appliance (FOA). Subjects and methods:  The investigational group was selected from orthodontic patients whom were examined clinically as soon as to get baseline information before active treatment.  The cluster included 210 patients; 45 males, 165 females (mean age 21.6 ± 4.5 years).  Clinical, demographic data and risk factors were collected in standard questionnaire then each individual was directed to carry out oral wash by a phosphate-buffered saline solution, which was expectorated and processed intended for the isolation of Candida species on Sabouraud’s dextrose agar. The isolated Candida species were identifying by culturing on chromogenic Candida agar and notice species-specific colony natures. Results:  The predominant Candida species isolated was C. albicans with OCAC rate equal to 13.8% extensively enhanced after the insertion of a FOA, as revealed by the oral rinse (P < 0.05) techniques. The results also revealed an increase of OCAC in male patients (24.4%) than female patients (10.9%),   21-25 years patients (17.1%), and regular smoking and Qat chewing were significant associated risk factors (OR=28.6, OR=10.7 respectively , P < 0.0001).  There was no significant association between C. albicans  colonization with oral hygiene in fixed Orthodontic patients. Conclusion:  As a whole, the current data suggest that the introduction of FOA is likely to promote OCAC. Moreover, it becomes visible that the routine oral hygiene procedures performed by these patients may not necessarily reduce OCAC while smoking and chewing Qat habits significantly increased OCAC in FOA. Also smoking and Qat chewing during FOA treatment should be banned if potential harmful effects are to be prevented. Further work with a larger sample size is required to confirm or deny these results.

Background and objective: Women at pregnancy are further susceptible to vaginal colonization and yeast infection. The responsibility of Candida colonization in the incidence of preterm birth is correctly established. Knowing regional epidemiology and identifying risk factors of preterm birth are important for management and preventive strategies. The aim of the study was to reveal the prevalence of Candida species in vaginal swabs of pregnant women and determine odds ratio of risks for vulvovaginal candidiasis (VVC). Methods:   Pregnant women attendance routine antenatal visits in Al-Olify –family Center in Sana'a city were registered into a cross-sectional study carried out from June 2018 to March 2019. The laboratory works were carried out in the National Center of Public Laboratories (NCPHL). Samples of vaginal swabs were taken from contributors after obtaining oral consent. The classification of the Candida species was done by culture on HiCrome Candida Differential Agar at 35 °C for 48 h for making of species-specific colors. Data of demographic, clinical and risk factors were collected in a pre-designed questionnaire. Results: A total of 190 pregnant women are included. The rate of VVC was 51.6%. Candida albicans accounted for 39.5% and non-Candida albicans accounted for 12.1% of isolates, mainly C. glabrata (4.7%), C. lipolytica (3.2%), and C. famata (2.1%). When VVC risk factors were considered, there were significant risk factors with the age group 20-24 years (61%, odds ratio (OR) = 1.8), first trimester of pregnancy (61.1%, OR = 1.7), Multipara of  parity (61.8%, OR = 1.9), low socioeconomic level (60.1%, OR =2.4), and illiteracy (68%, OR = 2.2). When clinical symptoms were considered, only 86.2% of affected females had clinical signs of VVC. Conclusions: There is a high probable rate of VVC is found among pregnant women in Yemen, undiagnosed and unnoticed; and this highlights the need for health authorities to develop strategies for diagnosing VVC, including vaginal swabs for candidiasis as a routine procedure for all pregnant women. This study also revealed a steady increase in time with a non-C. albicans species  prevalence rate. VVC syndrome management guidelines in Yemen should be revised to include a special protocol for pregnant women.

Background and aims: Fixed Orthodontic Appliances (FOA) act as diverse impact zones and modify microbial adherence and colonization, acting as unfamiliar reserves and potential sources of infection  This study was conducted to inspect the effect of the introduction of fixed orthodontic appliances on the growth and adherence (biofilm formation) of Candida species. And also to reveal the species distribution and antifungal sensitivity to isolated Candida species.  Material and methods: The trial group was chosen   from orthodontic patients whom were inspected clinically as soon as to get baseline information prior to active treatment. The group included 210 patients; 165 females, and 45 males, (mean age 21.6 ± 4.5 years). Clinical, demographic, and risk factor data were collected in a standard questionnaire and then each individual was directed to perform an oral rinse with phosphate-buffered saline, which was expectorated and processed proposed for the isolation and identification of Candida species by standard methods. After that, the isolated Candida species were tested for biofilm production by the phenotypic method i.e. Tissue culture palate methods (TCPM). Finally, antibiogram susceptibility pattern of oral Candida species was done by Kirby-Bauer disc diffusion method for amphotericin B, ketoconazole, and fluconazole. Results: The most common yeast colonized oral cavity after the introduction of FOA was C. albicans (72.5%), followed by C. glabrata and C. tropicalis  (12.5%), while Candida parapsilosis  only was 2.5%. The rate of formation of biofilms was 52.5% for all types of Candida, and it was found that biofilm formation occurs more frequently among C. tropicals  and C. glabrata (60%) than C. albicans (48.3%). All Candida species isolates were sensitive to amphotericin B and ketoconazole while resistance to fluconazole was found in 40% of C. tropicalis and 20% in C. glabrata  and 13.8% in C. albicans.  Conclusion: The present study proved that C. albicans is still the major isolate from the oral cavity after the introduction of FOA, but non-albicans species colonization is raised and FOA might be a factor for biofilm formation. The C. tropicalis and C. glabrata were more– biofilm-producers compared to C. albicans. The isolated species in the current study are less susceptible to fluconazole and drug resistant factor in the Candida species isolates was found to be associated with  biofilm formation.

Background and objectives: Vulvovaginal candidiasis is known to be a global issue of concern due to its association with economic costs, sexually transmitted diseases, and the escalation of genital tract infections.  This study aimed to determine the prevalence, species distribution and risk factors associated with Candida species causing vulvovaginal candidiasis. Subjects and Methods:  Non-pregnant women attending routine antenatal visits at Al-Olaifi-Family Center in Sana'a were enrolled in a cross-sectional study conducted from June 2018 to March 2019. Laboratory work was carried out at the National Center of Public Laboratories (NCPHL). Vaginal swabs were sampled from participants after oral consent was obtained. The swabs were inoculated in Sabouraud glucose agar supplemented with chloramphenicol and incubated at 37°C for 24 to 48 h under aerobic conditions in order to perform a fungal culture. Candida species were determined by culturing on HiCrome Candida differential Agar at 35°C for 48 h to produce species-specific colours. Data on demographic, clinical, and risk factors were collected in a pre-designed questionnaire. Results:  A total of 190 non-pregnant women were included. The prevalence of VVC was 22.1%. Candida albicans accounted for 16.3% and non-Candida albicans accounted for 5.8% of the isolates, mainly C. glabrata (3.2%), C. rugosa (1.05%), C. lipolytica (1.05%), and C. dubliniensis (0.53%). When VVC risk factors were considered, there were significant risk factors with age group 30-34 years (33.3%, odds ratio=2.1) and age group  ≥35 years (62.5%, odds ratio=10.3), residence in a rural area (39.5 %, OR=3.3), negative emotions (30.2%, OR=2.3), underwear replacement over 1 day (29.3%, OR=4.2), impure cotton underwear (29.4%, OR=4.9), while Condom use and vulvar cleaning before or after sexual life were found to be highly significant protective factors against VVC (p=0.008, 0.03, respectively). Conclusions: Guidelines for the management of VVC syndrome in Yemen should be revised to include a protocol specifically for women over 30 years of age. VVC undoubtedly poses a significant threat to women's reproductive health. Risk factors for VVC are varied, and include ages, health habits, history of the disease, and other aspects. It is necessary to take appropriate measures to avoid risk factors and to help reduce the prevalence of VVC among women of childbearing age.                    Peer Review History: Received: 3 May 2021; Revised: 23 June; Accepted: 30 June, Available online: 15 July 2021 Academic Editor: Dr. Ali Abdullah Al-yahawi, Al-Razi university, Department of Pharmacy, Yemen, [email protected] UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system.

Although Candida albicans is the main cause of fungal esophagitis, other species such as C. tropicalis, C. krusei and C. stellatoidea have also been implicated. Several studies have identified risk factors for C. albicans esophagitis. However, data for non-C. albicans species is still sparse. The aim of this study was to determine the etiology of Candida esophagitis in our medical centre over an 18-month period. Additionally, we aimed to investigate predisposing conditions for esophageal candidosis caused by different Candida species. A total of 21,248 upper gastroscopies were performed in Santa Casa Complexo Hospitalar between January 2005 and July 2006. The prevalence of Candida esophagitis was 0.74% (n = 158). C. albicans caused the vast majority of infections (96.2%), followed by C. tropicalis (2.5%), C. lusitaniae (0.6%) and C. glabrata (0.6%). There were 81 women (51.3%) and 77 men (48.7%). No case of mixed infection occurred. Concomitant oral candidosis was documented for 10.8% (n = 17). Most of cases (55.1%) involved outpatients. Around one fifth of patients in our cohort had no identifiable risk factors for esophageal candidosis (20.8%). Since nearly all infections were caused by C. albicans we were not able to determine risk factors for esophagitis caused by other Candida species.

Objectives:  Lower respiratory infections (LRTIs) are the leading reason of death infectious diseases in the world and the fifth leading cause of death in general. The study aimed to identify the general characteristics of LRTI, the causative bacteria and the results of sensitivity to antibiotics. Subjects and methods:  A multicentre prospective study was performed at 3 University hospitals. The study included 555 clinical diagnostic cases as LRTI cases, 328 male and 227 female, aged 3 to 69 years. Clinical and demographic data were collected in the standard questionnaire, and samples included sputum or bronchial lavage (BAL) staining and culture. Samples were cultured in 3 different bacterial media, blood agar and LJ slope, chocolate agar with Co2; cultures were then examined for possible bacterial pathogens of LRTI. Possible bacterial pathogens were isolated and identified by standard laboratory techniques, and microbial sensitivity testing was carried out by disc diffusion method. Results:  LRTI was recorded among all age groups and with less frequency in children less than 16 years of age. A large number of LRTI (36.2%) was not diagnosed, most in CAP (52.4%), followed by HAP (33.9%) while unidentified cases were lower in AECOPD (22.8%). CAP isolates are K. pneumoniae (26.2%), S. pyogens (12.3%), and S. pneumoniae (9%); in HAP are MSSA (24%), E. Coli (12.9%), MRAS (11.1%), K. pneumoniae (10.5%) and P. aeruginosa (7%); and in AECOPD are M. catarrhalis (47.2%), K. pneumoniae (17.2%), H. influnzae (10.7%) and P. aeruginosa (2%). In Gram-positive bacteria, high resistance to ampicillin/sulbactam (100%) and amoxicillin/clavulanate (100%) was recorded, while moderate resistance to amikacin, vancomycin, cefepime and moxifloxacin was recorded. In Gram-negative bacteria, a high resistance to 3rd g Cephalosporin’s  (68.5%) was recorded, while a moderate sensitivity to the other antibiotics tested was recorded. Conclusion:  There is a high rate of undiagnosed LRTI in Yemen and this highlights the need for health authorities to develop strategies to diagnose most of the causes of LRTI, including Mycoplasma, Chlamydia, and viral causes. No antibiotics are completely effective in treating LRTI in our area and antibiotic sensitivity should be performed in all cases.

The aim of this study was to assess the prevalence of denture-related stomatitis (DRS) in different attachment-retained overdenture wearers and its association with particular colonizing Candida species. Thirty-seven edentulous patients with implant-supported maxillary or mandibular overdentures were enrolled. A full clinical history was obtained, including details of patients' oral hygiene practices and the levels of erythema based on Newton's classification scale. Swabs were taken from the palate and investigated mycologically to identify the yeast colonies. Quantitative and qualitative microbiological assessments were performed, which included recording the total numbers of colonies (cfu), their color, and their morphological characteristics. Significant differences were found in cfu values between the attachment and inner surfaces of locator- and bar-retained overdentures (P &lt; .05). Candida albicans was the most common species in both evaluations, being isolated from 81.3% of bar-retained overdentures and 38.1% of locator-retained overdentures. DRS developed in all patients using bar-retained overdentures but in only 71.4% of those using locator-retained overdentures. No statistically significant relationship was found between bar and locator attachments according to smoking habit, overnight removal, or plaque and gingival indices (P &gt; .05).

Objective: The widespread prevalence of Giardiasis is a public health problem worldwide, and it is also common among Yemeni children. Hence, this work aims to identify the prevalent Giardia lamblia infection and risk factors among children admitted to health care centers in Amran governorate in Yemen. Methods: Three hundred and thirty-four stool samples were collected from infected children between March and July 2019 and the parasite is identified by light-microscope according to standard parasitology methods. Also, relevant data was obtained using a designed questionnaire. Results: The results showed that 181 cases (54.2%) were infected with G. lamblia infection. 57.5% of the infected children were from urban areas, while 42.5% of the cases were from rural areas. The highest incidence of G. lamblia was 60.3% among males compared to 47.5% among females. The results for age, residents and male children aged 8-14 years in both urban and rural areas recorded the highest prevalence of G. lamblia infection while the lowest was among females between 1 and 7 years and 8-14 years old, respectively, in the rural and urban area. Conclusion: In conclusion, as described in this work, multisectoral efforts are needed that include hygiene practices, personal hygiene habits, the provision of safe drinking water and the provision of sanitation systems to efficiently reduce this infection from all governorates of Yemen.

Background and objective: Urinary tract infections (UTIs) are the most common minor complication after operations, mostly due to bladder catheterization that used routinely during operations. This investigation seeks to determine prevalence rate, bacterial features, antibiotic sensitivity and risk factors for urinary tract infection in postoperative patients in tertiary hospitals in Sana’a, Yemen. Methods: This prospective analysis included 390 patients undergoing surgery between 2017 and 2018 at Al-Thawra Hospital. The study includes 258 male and 132 female between the ages 5 to 80 years. Clinical and demographic data and factors affecting UTIs were collected in the standard questionnaire, and the sample was obtained after catheter removal; or, in patients with a clinical indication of continuous catheterization, a sample was obtained after the replacement of a new catheter. The samples were cultured, examined for significant possible bacterial pathogens, isolated and identified by standard laboratory techniques, and microbial sensitivity testing was carried out by disc diffusion method. The operative characteristics associated with postoperative UTI were also analysis. Results: Postoperative UTI (POUTI) occurred in 144/390 (37%), and the predominant post-operative uropathogen was Escherichia coli (34%), followed by Pseudomonas aeruginosa 1(27%) and Staphylococcus coagulase negative (16.7%). In Gram-negative bacteria, high resistance to ampicillin (95%), nalidixic acid (63%), ceftriaxone (68%) and cotrimoxazole (55%) was recorded, while high sensitivity to amikacin (98%) and ciprofloxacin. (84%), cefotaxime (87%), gentamicin (87%) and imipenem (98%). In Gram-positive bacteria, high resistance to penicillin (90%), erythromycin (85%), and amoxicillin (78%) was recorded, while high sensitivity to aztreonam (94%), augmentin (83%),   ciprofloxacin (93%), cefotaxime (86%), gentamicin (85%), Rifampicin (100%) and vancomycin (97%).  The following characteristics are independently associated with postoperative UTI: female sex (OR 2.1, 95% CI 1.3–3.2), Rubber PTFE catheter (OR 4.7, 95% CI 1.99–11.4), longer duration of catheterization >10 days (OR 4.4, 95% CI 2.3–8.3), overweight (OR 1.7, 95% CI 1.1–2.9), and emergency surgery  (OR 1.9, 95% CI 1.2–3.0). Conclusions: POUTI remains an important problem in our hospitals and what complicates the situation is that all the causative microorganisms are MDR with few treatment options; and several risk factors were independently associated with POUTI.

Candida species are opportunistic yeasts affecting the genitourinary tract which causes the vulvovaginal candidiasis in the most female especially in developing countries. This study aims to determine the prevalence of vulvovaginal candidiasis caused by Candida species causing among pregnant women in Sana'a City, Yemen. This study was carried out at the department of microbiology of AL-Kuwait University Hospital. 250 vaginal swabs were collected and cultured on Sabouraud dextrose agar. Candida species identification and antifungal susceptibility testing were determined according to standard microbiological methods. The results showed that out of 250 samples, 63(25.2%) were positive for Candida species. It was found that the C. albicans (68.3%) was the most common species isolated followed by non-albicans species that are C. tropicalis (20.6%), C. glabrata (6.3%), and C. kefyr (4.8%). Also, it was recorded that the highest prevalence of Candida species was within group aged of 36-46 year. Susceptibility tests revealed that the most isolated species of C. andida were sensitive to nystatin (95%). miconazole was the next effective drug with 64% sensitive followed by amphotericin B (29%) and clotrimazole (24%). But only 6% of the isolates were sensitive to fluconazole. It can be concluded that the vulvovaginal candidiasis are quite common in Yemen country with a high prevalence. Also, the nystatin remains the effective agent against all isolated of Candida species. In contrast, the increase resistance of Candida species to fluconazole that commonly used antifungal is an alarming increase of vaginal candidiasis caused by antifungal-resistant Candida species.

Abstract Background: Candida are almost universal on normal adult skin and C. albicans is part of the normal flora of the mucous membranes of the respiratory, gastrointestinal, and female genital tracts. It is acknowledged that diabetic patients are more susceptible to infections caused by Candida albicans due to increased blood glucose and inability of immune system in eradicating the fungus. Studies suggest that Gutkha consumers are also at high risk of oral Candida carriage . Materials and methodology The participants were provided 10 ml of Normal saline and were asked to oral rinse for 1 minute. Oral rinse was collected in a sterile screw capped container and was transported in cold chain to microbiology laboratory. The oral rinse sample was inoculated onto the Sabouraud dextrose agar with Chloramphenicol and was incubated at 37°C for 3-4 days. The Colony forming Unit of candida was compared among diabetic and healthy controls. The candida albicans were identified by Germ tube formation. The Candida albicans isolates were subjected to Biofilm assay, Antifungal susceptibility Test, Haemolysin assay, Haemolysis degree and phospholipase assay. Result: This study reported 31.5% prevalence of oral Candida.The Candida carriage in CFU of diabetic population was statistically significant (p<0.05). The maximum isolates were found to be Biofilm producers. There was significant association between Gutkha consumers with oral Candida carriage. The study suggests that there is higher colonization of Candida in diabetic populations than in healthy population. The result also concludes that frequency of Candida in Oral cavity of Gutkha consumers was also higher (p<0.05). All isolated strains of Candida albicans were tested for antifungal susceptibility testing and 76.19% were found to be Resistant to Fluconazole and 50% were found to be resistant to Amphotericin B. There was statistical significance in Biofilm formation and fluconazole Drug resistance. Conclusion The findings indicated highest colonization of oral Candida in diabetic population and in Gutkha consumers. The greatest numbers of isolated Candida albicans were biofilm producer which showed greater frequency of Fluconazole drug resistance.
