Nontyphoidal Salmonella (NTS) is one of the major causes of bacterial foodborne infection. It is mainly manifested by self-limiting gastroenteritis in healthy individuals but can also cause severe complications including blood stream infection and mortality. The emergence of multidrug-resistant strains of Salmonella is becoming a global public health concern. This study is aimed at estimating the prevalence of Salmonella, identifying serotypes involved, and investigating antimicrobial susceptibility of the isolates among diarrheic patients attending private hospitals in Addis Ababa. We collected a total of 298 stool samples from diarrheic patients attending five private hospitals in Addis Ababa and isolated Salmonella according to standard microbiological techniques; the isolates were serotyped using slide agglutination and microplate agglutination techniques. Antimicrobial susceptibility test of the isolates was carried out using Kirby-Bauer disc diffusion assay according to Clinical Laboratory Standards Institute guidelines. Fourteen stool samples (4.7%) were positive for Salmonella, and Salmonella Kiambu was the most dominant serovar ( n = 7 , 50%) followed by S. Saintpaul ( n = 4 , 28.6%) and S. Haifa ( n = 2 , 14.3%). Three (21.4%) of the isolates were resistant to sulfisoxazole and tetracycline each and 2 (14.3%) to ampicillin. Resistance to two antimicrobials was detected only in 2 (14.3%) of the isolates, and none of the isolates were resistant to more than two antimicrobials. In conclusion, the current study showed low prevalence of NTS in diarrheic patients attending private hospitals in Addis Ababa. Although multidrug resistance to several antimicrobials was not detected in the isolates, prudent use of antimicrobials is recommended to guaranty the long-term use of the available antimicrobials.

Salmonellais one of the top causes of foodborne bacterial illnesses in humans. The primary sources of humanSalmonellainfection are food producing animals such as cattle, poultry, and swine. A cross-sectional study was undertaken to estimate the prevalence and to determine the serovar distribution and antimicrobial susceptibility profiles ofSalmonellaspp. isolated from fecal (n=567) and carcass swab (n=159) samples of slaughtered cattle at Addis Ababa Abattoir Enterprise and Kara’alo PLC, Abattoirs, in Addis Ababa, Ethiopia between January 2014 and April 2015.Salmonellaisolation was conducted according to Global Foodborne Infections Network Laboratory Protocol and isolates were confirmed by genus specific PCR and serotyped by slide agglutination test. Susceptibility of the isolates to 17 antimicrobials was testedusing the Kirby-Bauer disk diffusion method according to the guidelines of the Clinical and Laboratory Standards Institute. Out of the total 726 samples examined, 27 (3.7%) were positive forSalmonella. Salmonellawas detected in 4.1% (23/567) fecal and 2.5% (4/159) carcass swab samples. Twelve different serovars were identified and the most predominant serovars wereS. Dublin (n=10, 35.7%) andS. Virchow (n=5, 17.9%), followed byS. Braendrerup,S. Haifa, andS. Saintpaul which were isolated from 2 samples each (7.1%). All of theSalmonellaisolates investigated were resistant or intermediately resistant to four or more of the 17 drugs tested. High resistance rate was recorded to streptomycin 25 (89.3%), cephalothin 20 (71.4%), ampicillin 19 (67.9%), and amoxicillin+clavulanic acid 19 (67.9%). Resistance to five or more antimicrobials was detected in 20 (71.5%) of the isolates. Multidrug resistance to more than 7 antimicrobials was detected in 5 (17.9%) of the isolates. Isolation of such multidrug resistant strains ofSalmonellafrom slaughtered cattle poses a major public health concern. These findings imply the need for a strict biosecurity and regulation of antimicrobial use across the country.

Background. Diagnosis using reliable tools and treatment followingin vitroantimicrobial susceptibility tests are critical to proper addressing of antibiotic-resistantSalmonellainfection.Methodology. A cross-sectional study was conducted to assess the practice of diagnosis and treatment of salmonellosis in Addis Ababa. Tube Widal test (for blood samples only), culture, biochemical and carbohydrate fermentation, serotyping, and antimicrobial susceptibility tests were employed for both blood and stool samples.Results. Of all the diseases listed in the diagnosis, nontyphoidal (n=72, 13.71%) and typhoidal (n=47, 8.95%) salmonellosis were the second and third common diseases. Among the 288 blood samples, almost half were positive for O, H, or both antigens. However, only 1 (0.68%) of the positive blood samples yieldedSalmonellaisolate during culture. The study demonstrated low specificity (0.68%) and positive predictive value (48.78%) of Widal test. Conversely, the test showed 100% sensitivity and negative predictive values.Salmonellaisolates were identified from 7 (7.07%) of 99 stool samples. Two-thirds of salmonellosis suspected patients received antibiotic treatment. However, only half of the confirmed salmonellosis patients were treated with appropriate antibiotics. All of the isolates were susceptible to ciprofloxacin and ceftriaxone but resistant to ampicillin.Conclusions. Majority of the patients who participated in this study were wrongly diagnosed using symptoms, clinical signs, and tube Widal test. Consequently, most of the patients received inappropriate treatment.

Background: Incidence of multidrug resistant Klebsiella pnumoniae infections are increasing globally especially in ICUs. Aim: We evaluated the burden of colistin resistant K. pneumoniae (ColR KP) and the risk factors associated with the outcome of these patients. Methods: Consecutive patients developing K. pneumoniae infections were included. K. pneumoniae from endotracheal tube and catheterized urine sample, having cell count <105 cfu/ml, and which did not necessitate a change in antibiotics as per the treating physicians was considered as colonizer. Demographic and clinical details were collected and samples were processed as per standard protocol. Any growth was identified and its antimicrobial susceptibility was carried out by using Vitek 2 automated system. Minimum inhibitory concentration of >4 μg/ml for Colistin was considered as resistant. The resistant isolates were confirmed with Broth microdilution method. Risk factor associated with the outcome of ColR KP was analyzed. Findings: Burden of K. pneumoniae infection was 50.02 per 1000 admissions. K. pneumonie (n=155) was isolated from patients with ventilator associated pneumonia (84, 54.2%), followed by blood stream infection (49, 31.6%) and urinary tract infection (22, 14.2%). ColR KP and intermediate (ColI KP) isolates were 58 (37.41%) and 97 (62.6%) respectively. Among ColR KP infected patients 32 (55.1%) died whereas 26 (44.8%) patients were discharged. Higher mortality was witnessed in ColI KP cases (75, 77.3%) compared to ColR-KP cases (32, 55.1%) (p=0.004; OR=2.77; 95% CI=1.37 to 5.59). Colistin resistance and presence of central line were independently associated with mortality. Conclusion: Colistin resistant K. pneumoniae infections among ICU patients are on rise. Presence of central venous catheter and resistance to colistin were independent predictors of mortality.

Colistin is widely used in the treatment of multidrug resistant bacterial infections. Nephrotoxicity and neurotoxicity are risks associated with colistin use. We report the case of a 50 year old lady with end stage renal disease, treated with colistin for catheter related blood stream infection and developed muscle weakness and parasthesia. Concomitant use of meropenem may have precipitated neurotoxicity of colistin. Conventional hemodialysis was effective in reversing her signs and symptoms. Clinicians should be aware of the risk of neurotoxicity while using colistin, especially after a loading dose in patients with renal impairment. According to our knowledge, this is the first report of conventional hemodialysis reversing the neurotoxic effects of colistin.

This study highlights the level of microbial contamination of waterpipe components in selected area of Saudi Arabia and the resistance of selected bacteria to different antibiotics was determined. A series of biochemical tests, microscopic examination, and screening on Vitek 2 compact (bioMérieux Inc., USA) system were done to characterize the bacterial isolates. Out of 132 samples investigated, 7 mouthpiece samples and 48 water bowl samples showed positivity on culture. The percentage of contamination rate was higher in water bowl (69.69%) than in mouthpieces (10.6%) for all selected areas. A total of 55 bacterial isolates were identified which included Gram-negative (28) and Gram-positive (27) bacteria. Antimicrobial susceptibility data showed more resistance to bacteria isolated from water bowl than bacteria isolated from mouthpiece. In addition, one isolate which was confirmed as methicillin-resistant Staphylococcus aureus and Klebsiella pneumoniae was resistant to antibiotics which are commonly used to treat pneumonia. Water bowl of waterpipe instrument is significantly contaminated with different bacterial pathogens including multidrug-resistant and pneumonia causing bacteria, which are a real health concern among waterpipe smokers. The presented data could assist public health professionals to raise the concerns regarding cleaning practices of waterpipe components and highlights the risk posed among the waterpipe smokers.

ABSTRACT: The present study aimed to describe and characterize a nosocomial outbreak caused by a multidrug resistant Salmonella Typhimurium in hospitalized calves at a veterinary medical teaching hospital from Brazil. Sixty-three (96.9%) calves showed lethargy, hyperthermia and profuse diarrhea and despite treatment, 26 (41.2%) animals died. Five animals were necropsied and stool samples of six calves were collected. The isolated strains were subjected to antimicrobial susceptibility test by disc-difusion method and were fingerprinted by ERIC-PCR. Macroscopic lesions suggestive of salmonellosis, such as fibrinonecrotic enteritis and hepatosplenomegaly were observed. Salmonellosis was confirmed by isolation of S. Typhimurium from stool samples and organs from seven affected animals. Six out of seven isolates of S. Typhimurium, exhibited 100% of similarity at ERIC-PCR, suggesting occurrence of nosocomial transmission of S. Typhimurium among the hospitalized calves. All but one S. Typhimurium isolated were resistant to marbofloxacin, enrofloxacin, florfenicol, oxytetracycline and trimethoprim/sulfamethoxazole, antimicrobial agents largely used for humans and animal treatment. This is the first study of a nosocomial outbreak of multidrug resistant S. Typhimurium in a veterinary hospital in Brazil and highlighted the need for preventive measures to reduce the risks for inpatients and humans in contact with animals.

This study compared the antimicrobial susceptibility and prevalence of virulence genes in Salmonella enterica Typhimurium isolated from healthy and diseased pigs in Korea. A total of 456 Salmonella Typhimurium isolated from healthy (n = 238) and diseased (n = 218) pigs between 1998 and 2011 were investigated. In total, 93.4% of the Salmonella Typhimurium isolates were resistant to at least one antimicrobial agent tested. The isolates were most often resistant to tetracycline (85.7%), followed by streptomycin (83.6%), nalidixic acid (67.3%), ampicillin (49.3%), chloramphenicol (42.8%), and gentamicin (37.1%). Moreover, multidrug resistance phenotype and resistance to ampicillin, florfenicol, gentamicin, nalidixic acid, neomycin, streptomycin, and tetracycline were significantly higher (P &lt; 0.01) among Salmonella Typhimurium isolates from the diseased pigs compared with those from the healthy pigs. The most common resistance pattern observed in both groups of isolates was streptomycin-tetracycline. Overall, more than 96% of the isolates tested possessed invA, spiA, msgA, sipB, prgH, spaN, tolC, lpfC, sifA, sitC, and sopB virulence genes. The prevalence of orgA, pagC, and iroN were 50.2, 74.1, and 91.0%, respectively, whereas isolates carrying cdtB (1.5%), pefA (7.0%), and spvB (14.9%) were identified much less frequently. Furthermore, the prevalence of invA, lpfC, orgA, pagC, and iroN was significantly higher (P &lt; 0.01) among the isolates from the diseased pigs than in isolates from the healthy pigs. Our results demonstrated that, among diseased pigs, there was significantly higher resistance to some antimicrobials and greater prevalence of some virulence genes than in healthy pigs, indicating the role these factors play in pathogenesis. Multidrug-resistant Salmonella isolates that carry virulence-associated genes are potentially more dangerous and constitute a public health concern. Thus, continuous surveillance of antimicrobial resistance and virulence characteristics in Salmonella is essential.

Abstract Background: Tuberculosis (TB) remain a key global public health concern in Ethiopia. The study aimed at assessing prevalence and treatment outcomes of tuberculosis in the past five years. Methods: A retrospective data were collected from TB registry unit at Debre-Sina and Aremanya health centers from 2014-2018. A total of 221 TB patients who were registered and attended the direct observed treatment (DOTs) service in the health centers included in the study. Data were analyzed using SPSS version 20.Results: Among 221 TB patients, the prevalence of pulmonary TB was 175 (79.2%) of which 35.7% were smear positive, 43.4% were smear negative, 19.9% were with extra pulmonary TB and 0.9% were multidrug resistant. TB was found to be higher in males (52.5%) than females (47.5%). The highest TB cases (62%) occurred in the age group of 15 to 44 years (c2 =26.110, p= 0.002). The occurrence of all forms of TB was higher in urban (56.6%) than in rural settings (43.4%). The incidence of TB/HIV co-infection in the study area was 19% (c2=9.534, p= 0.023). Treatment success was increased from 2014 to 2018 in both health centers; however, TB detection rate was low (45.8%) in the study area. Conclusions: This retrospective study showed a decreasing trend of TB in the last five years. However, the study implies the need to give emphasis on pulmonary TB case detection for its elimination program.
