β-Lactamase Genes (<i>bla</i>CTX-M, <i>bla</i>SHV, <i>bla</i>TEM, <i>bla</i>OXA1 and <i>bla</i>OXA2) and Phylogenetic Groups in ESBL Producing Commensal <i>Escherichia coli</i> Isolated from Faecal Samples from Dairy Farm in the Municipality of Debar

Abstract β-lactamases are a diverse class of enzymes produced by bacteria that present major cause for resistance to β-lactams. In this study we analysed 159 fecal samples from dairy cows, the presence presumptive ESBL, AmpC, and carbapenemase-producing E. coli . Phylotyping was done using Clermont phylo-typing method, targeting arpA, ChuA, YjaA genes, along with DNA fragment TspE4.C2. Convetional PCR method used confirm bla genes among 39 phenotypically confirmed ESBL producing coli. The results showed CTX-M, SHV, TEM OXA1 in 28 (71.79%), 1 (2.56%), 29 (74.35%), 2 (5.12%) isolates, respectively Twenty (51.28%) isolates both CTX-M genes. strain carried SHV gene found carry as well, while one strains also carrying gene. ration between phylo-groups follows: 9 (23.07%) were assigned phyllo-group D; 14 (35.89%) B; 16 (41.02%) A. Out where identified, (74.35%) categorized multi drug resistant.
