21 strains of E. coli isolated from wild partridge birds - P. Perdix from the western part of Romania were studied. Through laboratory examination, the phenotypic characters of the isolated E. coli strains were highlighted. 21/70 (30%) of E. coli strains isolated from Perdix perdix fixed Congo Red, all isolated strains fermented lactose 21/21 (100%). Hemolytic activity was highlighted in a single strain of E. coli 1/21 (0.21%). The final identification of E. coli strains isolated from wild birds was done using the...

In cattle, uterine infections are one of the major causes of reproductive disorders. These bacterial infections are frequently treated with antibiotics, but their effectiveness must be evaluated, due to the continuous emergence of bacterial strains with multiple drug resistances. The research was conducted on several 190 samples from cows with a presumptive diagnosis of endometritis. The exploitation technology practiced at this farm is the free stall type. Samples were collected using sterile swabs and transporte...

The present study investigated the antimicrobial behaviour of E. coli and Salmonella spp. strains, isolated from pigs after their weaning age. Antimicrobial testing susceptibility by the Kirby-Bauer method allowed the identification of bacterial strains with multiple antibiotic resistance (58.02% for E. coli isolated strains and 47.27% for Salmonella isolated strains). Thus, it was noted that all 54 strains of E. coli showed resistance to trimethoprim; sulfathiazole with sulfacetamide and sulfabenzamide; sulphamet...
