This study was carried out to investigate the antibiotic resistance pattern of Enterococcus spp. and Staphylococcus aureus (S. aureus) isolated from chicken feces. All isolates showed high resistance to erythromycin (E) and tetracycline (TE). Of the 63 Enterococcus faecalis (E. faecalis) isolates, 73.0% were resistant to E and 98.4% to TE. Of the 44 Enterococcus faecium (E. faecium) isolates, 50.0% were resistant to E and 95.5% to TE. Of the 52 S. aureus isolates, 57.6% were resistant to E and 96.2% to TE. The prevalence of two and three drugs resistance pattern were 28.6% and 17.5% of E. faecalis, 40.9% and 25.0% of E. faecium and 38.5% and 23.1% of S. aureus, respectively.

Total of (104) urine samples were collected from patients suffering from urinarytract infection with different age groups from five hospitals in Baghdad (Ibn-Albalady, Al Yarmouk, Medical city, Baghdad hospital and Al-Kandy) from theperiod of the beginning of September 2015 to the end of December 2015.All sampleswere examined by traditional methods based on cultural characteristics, biochemicaltest and API 20 strep. The results revealed 50 isolates to Enterococcus and this wasconfirmed by polymerase chain reaction technique (PCR) based on amplification ofspecies specific genes. PCR were performed for E.faecalis and E.faecium in order toconfirm the presence of EfaA genes which code for Enterococcus faecalisendocarditis antigen using specific primer for gene.The results showed thatEnterococcus contain a proportion of 100% of EfaA.Biofilm production was detectedin E.faecalis and E.faecium by using two methods: Congo red agar method andmicrotiter plate method.Our results show that22(44%) of Enterococcus isolates werestrong biofilm production,25(50%)as moderate and 3(6%) as week biofilm productionby use Congo red method.In microtiter plate method, our results show that 20(40%) ofbacterial isolates were detected as strong, 26(52%) as moderate and 4(8%) as weekbiofilm production. This study aims todiagnosis of E.faecalis and E.faecium fromurinary tract infection of patients by traditional and molecular methods, detection ofEfaA gene and its role in biofilm production.

An observational study was conducted of chicken and turkey flocks slaughtered at federal processing plants in the province of Quebec, Canada. The objectives were to estimate prevalence of drug use at hatchery and on farm and to identify antimicrobial resistance (AMR) in cecal Escherichia coli and Enterococcus spp. isolates and factors associated with AMR. Eighty-two chicken flocks and 59 turkey flocks were sampled. At the hatchery, the most used antimicrobial was ceftiofur in chickens (76% of flocks) and spectinomycin in turkeys (42% of flocks). Virginiamycin was the antimicrobial most frequently added to the feed in both chicken and turkey flocks. At least 1 E. coli isolate resistant to third-generation cephalosporins was present in all chicken flocks and in a third of turkey flocks. Resistance to tetracycline, streptomycin, and sulfisoxazole was detected in > 90% of flocks for E. coli isolates. Antimicrobial resistance (AMR) was observed to bacitracin, erythromycin, lincomycin, quinupristin-dalfopristin, and tetracycline in both chicken and turkey flocks for Enterococcus spp. isolates. No resistance to vancomycin was observed. The use of ceftiofur at hatchery was significantly associated with the proportion of ceftiofur-resistant E. coli isolates in chicken flocks. In turkey flocks, ceftiofur resistance was more frequent when turkeys were placed on litter previously used by chickens. Associations between drug use and resistance were observed with tetracycline (turkey) in E. coli isolates and with bacitracin (chicken and turkey), gentamicin (turkey), and tylosin (chicken) in Enterococcus spp. isolates. Further studies are needed to provide producers and veterinarians with alternative management practices and tools in order to reduce the use of antimicrobial feed additives in poultry.

Lactic acid is an important carboxylic acid used in different aspects of life. In this study a pure isolate of homofermentative lactic acid bacteria Enterococcus faecium was isolated , and characterized by morphological examinations with physiological and biochemical tests. The present results have revealed the ability of the isolate to produce L- lactic acid in high concentration and low concentration of D- lactic acid in contrast with control. Lactic acid has been extracted and partially purified by Amberlite IRA400 resin column, the obtained extracted parts have been tested by carboxylic acid test in addition to High Performance Liquid Chromatography (HPLC) analysis which has showed that the concentration of L-lactic acid was 0.659g/l, while D-lactic acid was 0.174g/l in crude parts with two peaks appeared, one of area 322854 for L while no visible peak appeared for D because of small area 72214 in the figure, whereas the second peak of area 203238 may returned to the interference of D and L-lactic acid . Purified parts have reached to a purity of 72.3% for L-lactic and 38.2% for D-lactic acid also with one sharp peak for L with area of 43639 and no visible peak for D-lactic due to small area of 16713.

Objective-To measure the relationship between gross lesions in swine carcasses observed at a processing plant and Salmonella contamination and to determine whether nonexpert assessments of lesion status would correspond with swine pathologists' judgments. Animals-Carcasses of 202 conventionally raised and 156 antimicrobial-free pigs in a Midwestern US processing plant examined from December 2005 to January 2006. Procedures-4 replicates were conducted. For each, freshly eviscerated carcasses were identified as having or lacking visceral adhesions by a nonexpert evaluator and digital carcass photographs were obtained. Swab specimens were obtained from carcasses before the final rinse stage of processing, and bacterial culture for Salmonella spp and Enterococcus spp was performed. Subsequently, carcass photographs were numerically scored for lesion severity by 3 veterinary pathologists. Results were used to test the ability of lesion detection to predict bacterial contamination of carcasses and the agreement between judgments of the inexperienced and experienced assessors. Results-The probability of Salmonella contamination in carcasses with lesions identified at the abattoir was 90% higher than that in carcasses lacking lesions, after controlling for replicate identity and antimicrobial use. The receiver operating characteristic curve and Cohen κ indicated close agreement between lesion detection at the abattoir and by the 3 pathologists. Conclusions and Clinical Relevance-Findings indicated the presence of lesions could be used to predict Salmonella contamination of swine carcasses and that a nonexpert processing-line assessment of lesions could be used to discriminate between healthy and chronically ill swine before their entry into the human food supply.
