Abstract: In order to detect virulence factors in Shiga toxin-producing Escherichia coli (STEC) isolates and investigate the antimicrobial resistance profile, rectal swabs were collected from healthy sheep of the races Santa Inês and Dorper. Of the 115 E. coli isolates obtained, 78.3% (90/115) were characterized as STEC, of which 52.2% (47/90) carried stx1 gene, 33.3% (30/90) stx2 and 14.5% (13/90) both genes. In search of virulence factors, 47.7% and 32.2% of the isolates carried the genes saa and cnf1. According to the analysis of the antimicrobial resistance profile, 83.3% (75/90) were resistant to at least one of the antibiotics tested. In phylogenetic classification grouped 24.4% (22/90) in group D (pathogenic), 32.2% (29/90) in group B1 (commensal) and 43.3% (39/90) in group A (commensal). The presence of several virulence factors as well as the high number of multiresistant isolates found in this study support the statement that sheep are potential carriers of pathogens threatening public health.

Antimicrobial Resistance Profile

The alarming increase of antibiotic resistance of Escherichia coli has posed a great challenge in the public health sector. Thus, this microorganism is a leading cause of different human infections and it can be found in various environments. The aim of this study is to investigate the antimicrobial susceptibility patterns and the multiple antimicrobial resistance profile of Escherichia coli isolates obtained from some hospitals in Abeokuta, Ogun State, Nigeria. Isolates of E. coli were obtained from different clinical samples and were re-identified morphologically and biochemically. E. coli was isolated from 30% out of a total of 70 clinical samples analyzed for isolation and identification. The isolation rate of E. coli was highest in urine samples 10(47.6%) when compared to other clinical samples. There was significant increase in the resistance rate of E. coli to tetracycline (14.3%), ceftazidime (14.2%), and ampicillin (14.2%).Also, an increased sensitivity rate to augmentin (71.4%), ofloxacin (66.7%), cefuroxime (66.7%), ciprofloxacin (61.9%) and ceftazidime (61.9%) were observed. Furthermore, the overall multiple drug resistance rates obtained was 14(66.7%) and it was established that, multiple antimicrobial resistance of the E. coli isolates was plasmid mediated. E. coli isolates exhibited high resistance rate to multiple antimicrobial agents, however, its sensitivity to augmentin, ofloxacin, cefuroxime, ciprofloxacin and ceftazidime showed that these antimicrobials are still effective against E. coli infections in the study area.

ABSTRACT Enteric diseases of bacterial origin are frequent in the pig industry, of particular notoriety are the colibacillosis that mainly affect piglets and cause great damage to the swine industry worldwide. The aim of the study was to analyze phylogenetics, to detect biofilm production, and to determine antimicrobial resistance profile in 126 strains of Escherichia coli isolated from swabs obtained from fragments of the small intestines of 235 healthy pigs killed in slaughterhouses in Pernambuco (Brazil) using polymerase chain reaction (PCR), adherence to microplates test and disc diffusion technique. Of the analyzed samples, 88.10% (111/126) were classified in phylogenetic group B1; 4.76% (6/126) in group D; 3.97% (5/126) in group B2 and, 3.17% (4/126) in group A. Antimicrobial resistance rates observed were: lincomycin 100% (126/126), erythromycin 100% (126/126), chlortetracycline 94.44% (119/126), cephalothin 51.59% (65/126), ampicillin 38.89% (49/126), sulfamethoxazole + trimethoprim 37.3% (47/126), ciprofloxacin 19.84% (25/126), norfloxacin 14.29% (18/126), gentamicin 8.73% (11/126) and, chloramphenicol 5.55% (7/126). Multiple antibiotic resistance (MAR) ranged from 0.2 to 0.9. Of the strains tested 46.03% (58/126) produced biofilm, and 99.21% (125/126) of the strains exhibited multi-resistance. Further studies are required to elucidate the importance of each phylogenetic group in pigs and to prevent the propagation of multi-resistant E. coli strains.
