Abstract
The present research work was carried out to characterize the antibiotic resistance of
Salmonella serovars associated with invasive salmonellosis in selected hospitals in Katsina
State. A total of 300 blood samples was collected from the patients at three General hospitals
[General hospital Katsina, Daura and Baure] and were processed according to standard
microbiological technique for isolation and identification ofSalmonella typhiand Salmonella
paratyphiA from 14 samples,the result of serotyping (slide agglutination) of the isolates
indicates that nine (9) serovars belonged to D group while five (5) of the serovars belonged to
A group. The antibiotic susceptibility test that was carried out among the isolates against
seven (7) antibiotics showed 88.9% resistance to ampicillin by Salmonella
entericaserovarTyphi only, 100% resistance to penicillin G by both serovars and 100%
sensitivity to ampicillin (by Salmonella paratyphi A only), Chloramphenicol, Gentamicin,
Cephalex, Ofloxacin and Trimethoprim – sulfomethoxazole. The PCR analysis detected the
presenceof blaTEM-1gene in eight (8) serovars of Salmonella entericaserovarTyphi only.This
study confirmed the presence of Salmonella entericaserovarTyphi and Salmonella
entericaserovarParatyphi A as the cause of invasive salmonellosis in the study, their
susceptibility and resistance to antimicrobial agents. The study emphasized the use of
antibiotics likeofloxacin, cephalex chloramphenicol and septrin for treating enteric fever.
