Occurrence and Characterization ofSalmonellaHiduddify from Chickens and Poultry Meat in Nigeria

Abstract

The objective of this study was to determine the prevalence of Salmonella serovars and the antimicrobial susceptibility in chickens and poultry meat products in rural areas in Nigeria. The study was an observational cross-sectional investigation in which the target population included exotic and local chickens in Maiduguri main markets, chickens from farms, and free-range local chickens. A total of 865 samples were collected from feces, kidney, lungs, cecum, intestine, liver, heart, gizzard, and cloacal swabs from 525 different chickens. Salmonella was isolated from 130 of the samples. A stratified random sampling technique was used to select 41 isolates out of the 130 strains for serotyping, pulsed-field gel electrophoresis (PFGE), and antimicrobial susceptibility testing. Thirty-nine out of the 41 samples serotyped yielded Salmonella Hiduddify; two yielded a rough Salmonella serovar. The 39 Salmonella Hiduddify isolates and the two rough isolates were highly similar by PFGE typing, indicating that all of the isolates were of the same serovar. A low frequency of resistance was found among the isolates, except for resistance to ciprofloxacin for which 23 (56%) of the isolates tested exhibited resistance. This study documents for the first time the isolation of Salmonella Hiduddify in chickens and shows that this serovar is widespread in rural areas in Nigeria. It also documents a high frequency of fluoroquinone resistance in the isolates indicating the presence of selective pressure in the environment. Further studies should be conducted to reveal if the serovar is present in eggs and causes salmonellosis among the general population.

Antimicrobial Resistance in Food Animals and the Environment in Nigeria: A Review

“…This category included 42 studies, with the inclusive eligibility criteria in which diverse phenotypic or genotypic methods were utilized ([14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55], Tables S1–S3). These studies sought to detect the presence and extent of AMR in collected samples with a selected panel of antibiotics.…”

“…The 80 studies excluded did not directly relate to the objectives or yielded information that could be subjected to organized peer review and data analysis. The 59 included studies were sorted into three categories of 42 antimicrobial resistance studies [14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55], 16 antimicrobial residue studies [56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,71], and 1 antiseptic or disinfectants study [72]. The PRISMA-style flowchart was modified and used for this analytical review (Figure S1) [73].…”

Persistence of fluoroquinolone-resistant Salmonella enterica serovar Kentucky from poultry and poultry sources in Nigeria

“…Practices such as the intensive (deep litter) and semi-intensive systems practised by most poultry establishments coupled with the unhygienic environment and poor management practices probably contribute to the spread and emergence of the clone and its widespread distribution and cross contamination of litter, reptiles, water, rodents, and lizards [14,15].…”

“…Other serovars have also been reported in different parts of the world – S. Paratyphi B var. Java in the Netherlands [33], S. Hiduddify in Nigeria [34], S. Infantis in Hungary [35], S. Hadar, S. Heidelberg, S. Manhattan and S. Virchow in Algeria [36], indicating temporal increase of a particular serovar in a specific region.…”
