Abstract Objectives Food borne diseases are one of the main important issues in the world. Escherichia coli are considered as the most prevalent food borne pathogen. A cross sectional study was conducted from January 6- 2018 to September 10-2019 on cloacae swab; farm and market’s egg at Jimma town to isolate, identify and determine antimicrobial susceptibility patterns. Result Out of 415 total samples, 156 (37.59%) were identified as E. coli from farm eggshell 21/83 (25.30%), farm egg content 12/83 (14.46%), cloacae swab 42/83 (50.60%) and market egg shell 45/83 (54.23%). In the current study antimicrobial susceptibility test of E. coli isolates from different sample types revealed varying degree of susceptibility to antimicrobial. Isolated E. coli was highly susceptible to Ciprofloxacin (100%), Gentamicine (100%), Streptomycin ( 96.4% ) , sulfonamides (94%), Kanamycin (91%), Chloramphenicol ( 89.5% ) , tetraccine (78.9%) , Trimethoprim (75%) these are considered appropriate for empirical treatment of E. coli in the study area. Moreover, resistance of isolates with 100%, 75% 50%, 25%, 1.6% and 0.5% was developed to ampicillin, neomycin, cefoxitin oxytetracycline , Streptomycin and tetraccine respectively. The presence of E.coli within egg/and chicken can pose serious public health problems. The appropriate hygienic practices of eggs at both farms and markets should be under taken.

Escherichia coli is one of the leading causes of early-onset neonatal sepsis in many industrialized countries. However, there is a lack of studies on Escherichia coli colonization in women and neonates. The study aimed at determining the prevalence Escherichia coli among pregnant women and newborns, perinatal transmission, antimicrobial susceptibility, and risk factors for neonatal colonization. Material and Methods. In this prospective, cross-sectional study, 827 infants born to 808 mothers were enrolled. The study was carried out from October 1, 2006, to June 30, 2007. Women were screened for E. coli carriage at 35–37 weeks of gestation or on admission for premature rupture of membranes and delivery; neonates, within 15 minutes of their lives. Risk factors for colonization were collected by a questionnaire and were recorded during labor. Results. Maternal E. coli colonization rate was 19.9%; neonatal, 14.4%; and transmission rate, 21.4%. Less than one-fourth (22.7%) of neonatal E. coli strains were resistant to ampicillin. Logistic regression analysis revealed that anal sexual intercourse (OR, 3.91; 95% CI, 1.87–8.19), one sexual partner (OR, 2.01; 95% CI, 1.30–3.11), maternal vaginal Escherichia coli colonization (OR, 1.81; 95% CI, 1.12–2.93), maternal body mass index of ≤27 (OR, 1.77; 95% CI, 1.15–2.73), and maternal education lower than university level (OR, 1.70; 95% CI, 1.06–2.74) were associated with neonatal Escherichia coli colonization. Conclusions. The prevalence of maternal Escherichia coli colonization was higher in this study than other studies (19.9%). Neonatal Escherichia coli colonization was 14.4%. The resistance of Escherichia coli isolates to ampicillin was not high (22.7%). Improvement of maternal education and modification of mothers’ sexual habits need to be undertaken to prevent neonatal Escherichia coli colonization.

Background. In most African countries including Ethiopia, Neisseria gonorrhoeae infections were diagnosed clinically and its antibiotic susceptibility was rarely tested. This study aimed to determine the prevalence and antimicrobial susceptibility patterns of N. gonorrhoeae among suspected patients attending private clinics in Jimma, Ethiopia. Methods. Institution-based cross-sectional study was conducted to determine the prevalence and antimicrobial susceptibility pattern of N. gonorrhoeae isolated from urogenital specimens. Urogenital samples were collected aseptically and then transported using Amie’s transport media and processed in a microbiology laboratory following the standard protocol. Results. Of the total 315 samples examined, 31 (9.8%) were confirmed to have gonococcal infection. Of these, 30 (96.7%) were females. High proportion of culture confirmed cases (18 (12.5%)) were observed in the 20–24 age group. All of the identified organisms were susceptible to ceftriaxone and had high resistance to penicillin (80.6%) and tetracycline (54.8%). Conclusion. The prevalence of gonococcal infection is high. In the current study, participants who have no information about sexually transmitted infection were more likely to be infected by N. gonorrhoeae. According to our study, ciprofloxacin is effective against gonococcal infection.

Abstract Background: Escherichia coli O157:H7 is an emerging and major zoonotic foodborne pathogen with an increasing concern for the emergence and spread of antimicrobial-resistant strains which may results in sporadic cases to serious outbreaks in the whole world. Cattle have been identified as a major reservoir of the pathogen. This study aimed to isolate and characterize Shiga toxin-producing E. coli O157:H7 from raw milk, yogurt, and meat of bovine origin and determine their antimicrobial susceptibility pattern. Methods: A cross-sectional study was conducted from December 2014-June 2015 and a total of 284 milk and meat were collected from different sources in Mekelle. The collected samples were analyzed for the presence of E. coli and Shiga toxin-producing E. coli O157:H7 and determination of their antimicrobial susceptibility pattern following the standard bacteriological and molecular techniques and procedures, and antimicrobial sensitivity test. Results: Out of the total 284 samples, 70(24.64%) were positive bacteriologically to E. coli and 14.29% were found to be Shiga toxin-producing E. coli O157:H7. All (100%) E. coli isolates carried the pal and 41.67% eae gene (EHEC). Of these EHEC isolates 40% and 60% were positive for stx1 and stx2, respectively. E. coli isolates were showed the highest level of sensitivity for Gentamycin (91.7%) but the highest level of resistance to Amoxicillin (95.8%). Of the tested isolates, 18(75%) of E. coli showed multiple antimicrobial resistance.Conclusions: The current study revealed the occurrence of Shiga toxin-producing E. coli O157:H7 in foods of bovine origin in the study area. So, there is a chance of acquiring infection via the consumption of raw or undercooked food of bovine origin. Thus, awareness creation should be made on foodborne disease caused by Shiga toxin-producing E. coli O157:H7 with due consideration on the safe handling and consumption of food of animal origin.

Introduction: Escherichia coli is one of the most important agents involved in healthcare-associated infection, and resistance to quantum ammonium compounds (QACs) has become a major challenge for infection control practitioners. The aim of the current study was to determine the frequency of qacE and qacEΔ1 genes in E. coli isolated from hospitalized patients in Qazvin, Iran. Material and Methods: In the current cross-sectional study, 102 E. coli were collected from hospitals of Qazvin. All bacterial isolates were identified using standard laboratory methods and the antimicrobial susceptibility was evaluated by Kirby-Baer test. The presence of qacE and qacEΔ1 genes was investigated using polymerase chain reaction (PCR) technique. Results: In this study, 65 (63.7%) isolates showed a multidrug resistance (MDR) pattern which was resistant to at least three classes of antimicrobials including ß-lactams, aminoglycosides, and fluoroquinolones. The highest rates of resistance were observed against cefotaxime (75.5%) and nalidixic acid (66.7%). The PCR showed that 5 (4.9%) isolates harbored qacE gene, 62 (60.8%) isolates qacEΔ1, and 10 (9.8%) isolates carried both genes, simultaneously. There was a significant relationship between the QACs resistance and MDR pattern (P=0.03). Conclusion: This study indicated a significant resistance rate against disinfectant compounds in the studied hospitals. However, more attention should be paid to this critical issue in the infection control committees of the hospitals.

Abstract CONTEXT: Diarrheagenic Escherichia coli (DEC) is the leading cause of infectious diarrhea in developing countries. On the basis of virulence and phenotypic characteristics, the DEC is categorized into multiple pathotypes. Each pathotype has different pathogenesis and geographical distribution. Thus, the proper management of disease relies on rapid and accurate identification of DEC pathotypes. AIMS: The aim of the study was to determine the prevalence of DEC pathotypes in India. MATERIALS AND METHODS: A cross-sectional study was carried out between January 2008 and December 2012 at Jawaharlal Nehru Medical College and KLES Dr. Prabhakar Kore Hospital and Medical Research Center, Belgaum (Karnataka), India. A total of 300 stool samples were collected from diarrhea patients with age >3 months. The DEC was identified by both conventional and molecular methods. RESULTS: Of 300 samples, E. coli were detected in 198 (66%) and 170 (56.6%) samples by culture and polymerase chain reaction, respectively. Among DEC (n = 198) isolates, eae gene (59.5%) was the most prevalent followed by stx (27.7%), east (27.2%), elt (12.6%), est (10.6%), ipaH (5.5%), and eagg (1.5%) genes. On the basis of virulence genes, enteropathogenic E. coli (33.8%) was the most common pathotype followed by Shiga toxin-producing E. coli (STEC, 23.2%), enterotoxigenic E. coli (ETEC, 13.6%), enteroinvasive E. coli (5.5%), enteroaggregative heat-stable enterotoxin 1-harboring E. coli (EAST1EC, 4.5%), STEC/ETEC (3.5%), STEC/enteroaggregative E. coli (STEC/EAEC, 1.0%), and EAEC (0.05%). CONCLUSIONS: The hybrid DEC is potentially more virulent than basic pathotypes. The pathotyping should be included in clinical settings for the proper management of DEC-associated diarrhea.

Abstract Objectives The prevalence of ESBL-producing Escherichia coli (ESBL-E. coli) in community-acquired urinary tract infections (UTI) has been increasing worldwide since 2000, but with large geographical variations. The aim of this study was to determine whether the ESBL-E. coli rate in urine samples from individuals with community-acquired UTI was associated with the local socio-economic, environmental, agricultural and healthcare characteristics. Methods This was a cross-sectional study in western France using data on antibiotic susceptibility of E. coli isolated from urine samples of individuals with community-acquired UTI analysed in non-hospital laboratories from 2015 to 2017. The ESBL-E. coli rate was calculated for each laboratory. Data on socio-economic characteristics, human antibiotic consumption, hospital bed density, animal farming density and percentage of agricultural land and surface water were retrieved at the municipality level and aggregated by study area. Their association with ESBL-E. coli prevalence was quantified using multivariate linear regression models with a backward selection. Results From 358 291 E. coli isolates from urine samples tested in 92 laboratories, the mean ESBL-E. coli prevalence for the study period was 3.30%. In an adjusted model, the ESBL-E. coli rate was significantly (P < 0.05) and positively associated with the local percentage of people >65 years old, third-generation cephalosporin use (DDD/1000 inhabitants), number of hospital beds/km2, poultry density, pig density and percentage of agricultural land. Lower deprivation was associated with a higher ESBL-E. coli rate. Conclusions Several anthropogenic factors (primary care, hospitals and animal farming) are associated with the local ESBL-E. coli rate in community-acquired UTI. These results could contribute to improve risk management, including identification of at-risk patient groups.

Cytolethal distending toxin (CDT) is a heterotrimeric AB-type genotoxin produced by several clinically important bacterial pathogens. To better understand the risk of CDT within the food supply and human gastroenteritis patients in Qatar, we investigated the frequency of the CDT gene (cdtB) among Escherichia coli (E. coli) strains recovered from food products, animal livestock, and human gastroenteritis patients. In this cross-sectional study, E. coli isolates were screened for cdtB using polymerase chain reaction (PCR). cdtB positive strains were further examined for E. coli cdtB gene types (cdt I, cdt II, cdt III, cdt IV and cdtV), serotypes O157: H7, and non-O157 Shiga toxin-producing E. coli O26, O45, O103, O111, O121, and O145. Screening for other virulent factors, stx (Shiga toxin gene) and eae (gene that encodes intimin) genes were also performed. The cdtB gene was detected in E. coli isolates sourced from all three groups; animal livestock (17%), retail foods (8%), and human gastroenteritis patients (3%). Although the incidence of cdtB gene harboring E. coli is relatively low among gastroenteritis patients, there is still a risk of infection from animal reservoirs as well as retail food products. Among the three groups, E. coli isolates from humans had the lowest occurrence of cdtB, stx, eae, and O157: H7. Furthermore, we advise implementing monitoring at the food production and preparation level.
