Multidrug Resistant Salmonella Species Isolated from Dam Water from Parts of Kaduna State, Nigeria

Abstract

Dam water from parts of Kaduna was investigated for the presence of multidrug resistant Salmonella spp. A total of four hundred and fifty water samples) were sampled from (Galma, Shika and Kubanni Dams. The samples were collected over a period of Ten months (October 2016– July 2017). The isolates were enriched in Selenite broth and streaked on Salmonella Shigella agar (SSA). From these samples, 27 isolates were confirmed to be Salmonella arizonae, 14 were Salmonella pullorum while 2 were Salmonella cholearesuis. They were all selected for antibiotic susceptibility testing using the Kirby-Bauer method. The isolates were tested for resistance to ten antibiotics. The highest resistance observed was to Ampicillin, Nalidixic acid and Amoxiclav 43(100%) while all the isolates showed susceptibility to Imipenem and Ceftriaxone 43(100%). Multidrug resistance were observed in 24(55.8%) of the isolates which showed resistance to six of the antibiotics while the least was 3(7.0%) showing resistance to four antibiotics. The isolates that were resistant to the highest number of antibiotics were obtained from Shika dam and Galma water samples.. The isolation of antibiotic resistant bacteria in reservoir water is of public health concern due to the possibility of transferring multiple antibiotic resistances in the environment
