An Outbreak of Lactose Fermenter Multidrug Resistant Salmonella enterica serova typhi in Sulaymani City, Iraq

In order to present the clinical microbiology characteristics of outbreaks of lactose fermenting S. enterica serova typhi, thirty lactose fermenting (L+) and three nun-lactose fermenting (L-) Salmonella entereca serova typhi were isolated from blood of patients suffering from typhoied fever in indor and outdor of Sulaymani city-Iraq. The isolated S. enterica exihibited same charecterstics as the type strain and L-S. enterica except for ONPG production. Serological examination reveled that all L+, L- and standered strain possesed the antigenic formula as S. enterica. The apperence of all L+S. enterica colonies on different media was similar to that of E. coli. The L+S. enterica isolates were 100% resist to Ampicillin, Cefalosporin, Chloramphenicol, Gentamycin, Tetracyclin and Trimethoprim antibiotics, While L-were sensitive to Amikacin, Cefalosporin, Cefotaxim, Ciprofloxacin, Chloramphenicol and Gentamycin. However 43.3% of L+S. enterica isolates were resist to all tested antibiotics, 6.7% were resist to 10 antibiotics out of eleven, 30% resist to nine antibiotics, 6.7% resist to 8 antibiotics, while 13.3 were resist to seven antibiotics.
