Introduction: Candida spp. frequently cause hospital-acquired bloodstream infections (BSI) with a high mortality rate (up to 70%). We analyzed the frequency, infection characteristics, potential predisposing factors, susceptibility to antifungal drugs, biofilm production and other virulence characteristics of Candida spp. isolates obtained from a tertiary care hospital in Niš, Serbia, during a one year period. Methods: Medical histories, characteristics of isolated strains and drug susceptibility, as well as the effect on the function of isolated macrophages and other virulence features were evaluated. The obtained results were subjected to student’s t-test and multivariate statistical analyzes. Results: Herein we report an annual incidence of 3.65 cases of C. albicans, C. lusitaniae and C. lipolytica infections per 105 population. Out of eight isolated strains, two (25%) were shown to be strong biofilm producers, one (12.5%) caused hemolysis on blood agar and in two (25%) cases macrophages were able to completely eliminate the yeast colonies. Chronic kidney disease, diabetes, malignant and other diseases were present in 37.5, 62.5, 50 and 75%, respectively, in the study group. All patients with Candida BSI received antifungal therapy (amphotericin B), however, hospital mortality was observed in 25% of patients. Conclusions: Evaluation of local Candida epidemiology, antifungal susceptibility and virulence factors, as well as personalized patient risk factors are important for the surveillance of Candida BSI, especially in intensive care unit patients and may contribute to the improved options and outcome for patients with Candida BSI.

Common Infections

Recent years, due to increased usage of antifungal treatment worldwide, there is an increased chance of rising resistance among antifungal drugs too. Dermatophytic infections causes’ superficial mycosis and it affects skin, hair and nail. These infections are more common and antifungal drugs are used everywhere to treat those common infections. To conduct a study by determining the antifungal susceptibility pattern in dermatophytic isolates from patients attending dermatology OPD in a tertiary care hospital. A total of 217 samples like hair, nail and skin scrapings were obtained and isolation of dermatophytes was done. Antifungal susceptibility testing for dermatophytes was performed by micro broth dilution method. Antifungal drugs tested were Griseofulvin, Fluconazole, Itraconazole and Ketoconazole. Minimum inhibitory concentration for each drug for fungal isolates was tested and results studied. Fluconazole showed a higher MIC values in the range of 1-8µg/ml. Itraconazole showed the lowest MIC values by micro broth dilution method. Since there is limitation of standard guidelines and protocol, meticulous research must be conducted on effect of antifungals and derive at universally implementable guidelines.

Pregnant Females

Asymptomatic bacteriuria (ASB), most common during pregnancy is endangering as it may lead to maternal and fetal complications. Various organisms causing ASB combats the host defense mechanisms through virulence factors exhibited by them. In order to understand the pathogenesis and sequelae of infections, virulence factors like hemolysin production, gelatinase production, haemagglutination, biofilm production and many more should be identified. Hence, we aimed at studying the distribution of virulence factors among each organism causing asymptomatic bacteriuria in pregnant females attending a tertiary care hospital. Materials and Methods: This cross-sectional study was conducted in Department of Microbiology over a period of one year and six months (January 2014 to June 2015) at a tertiary care teaching hospital. A total of 1000 urine samples were included in study taken from pregnant women with asymptomatic bacteriuria. Isolation, identification of organisms was done according to standard microbiological techniques and virulence factors for individual organisms by phenotypic method were tested. Results: Out of 1000 samples screened for ASB, organisms were isolated in following frequency distribution: Escherichia coli, the commonest 54/118 (45.76%), Klebsiella pneumoniae 21/118 (17.80%), Staphylococcus aureus 19/118 (16.10%), Staphylococcus saprophyticus 10/118 (8.45%), Enterococcus faecalis 9/118 (7.63%), Pseudomonas aeruginosa 3/118 (2.54%) and Proteus mirabilis 2/118 (1.69%). Virulence factors for individual organisms and biofilm detection for all organisms were done. Conclusion: Multifactorial mechanisms determine the pathogenicity of an organism and it needs to be explored by analyzing each virulence factor and mechanism of invasion in combating the host defense systems. Hence analyzing the phenotypic expression of each virulence factor helps in better understanding about the complications of ASB.

The main objective of this study was to determine the prevalence of non-albicans Candida among the patients attending a tertiary care hospital in Kathmandu, Nepal. Candida spp. isolated from different clinical samples (sputum, urine, vaginal swab, blood, endotracheal (ET) secretion, pus) from 250 patients between the period of February 2013 and December 2015 were included in the study. Of those 250 patients, 20% were immunocompromised. Sabouraud dextrose agar was used for the isolation of Candida spp. and the identification was performed on the basis of colony morphology, Gram’s stain, India ink preparation, germ tube test, temperature tolerance test, characteristic color change in CHROMagar, chlamydospore production, sugar fermentation test and sugar assimilation test.Out of total 300 Candida spp., majority were isolated from sputum (43.33%) followed by urine (40%) and vaginal swab (6.67%). Of total 151 (50.33%) non-albicans Candida, the most common species isolated were C. tropicalis (62.25%) followed by C. glabrata (23.84%). High prevalence of non-albicans Candida among the patients attending a hospital in Kathmandu, Nepal was noted.
