“…This occurrence of a high frequency of multidrug resistance reported in this study, in addition to the occurence of a total of 18 multi-resistance patterns, demonstrate a potential for the likelihood of chemotherapeutic failure that may be connected with the use of these antimicrobials in the area. These findings corroborate the report on Salmonella isolates from poultry by other researchers (Ahmed et al, 2017, Adesiyun et al, 2014a, Oluwasile et al, 2014, Elmadiena et al, 2013, Mir et al, 2010.…”

“…The study was conducted on selected poultry farms in Kwara State, Nigeria during the period of November, 2015 to March, 2016. Kwara state is located between latitudes (8° 30′N) and longitudes (5° 00′E) and it is the transit state that connects southern and northern parts of Nigeria (Ahmed et al, 2017). Local Government areas where poultry farms are concentrated within the state were purposefully selected for the study ( Table 1).…”

Salmonellosis is a major public health hazard globally. This study was designed to determine the antimicrobial resistance among Salmonella serovars isolated from selected poultry farms in Kwara State, Nigeria between 2015 and 2016 using a cross sectional approach. A total of 58 Salmonella isolates were serotyped, 13 different serovars were identified and subjected to antibiotic susceptibility test using disc diffusion method. All the isolates (100%) exhibited resistance to at least one antimicrobial agent. All of the isolates exhibited 100% resistance to ampicillin, 65.5% of the isolates showed resistance to cefotaxime while 63.8% of the isolates were resistant to either of ciprofloxacin and nalidixic acid. Low level of resistance was observed for neomycin (22.4%) compare to other antimicrobials. S. enterica ser. 4, 12, 27: z:-exhibited resistance to all antimicrobial agents. Considering the types of samples that were positive for Salmonella across different local government areas, frequencies of resistance were statistically significant only to gentamicin (P =0.016) in Ilorin west local government area, only nalidixic acid (P =0.014) in Irepodun local government area, only compound sulfonamide (P =0.002) in Asa local government area and streptomycin (P =0.025) in Ilorin-South local government area. The results indicated the relatively high resistance to the antimicrobial agents tested and the multi-drug-resistance among the Salmonella serovars. These observations pose therapeutic concerns on poultry farms in the study area and may serve as potential sources of multi-drug-resistant Salmonella transmission to the humans.

“…Salmonellosis in poultry is endemic worldwide, causing morbidity and mortality and, thus, economic losses (Abiodun et al 2014; Ahmed et al 2017; Akter et al 2007; Kwon et al 2010). The disease is very significant by virtue of the fact that Salmonella can be transmitted vertically from parent to offspring.…”

Salmonellosis is a major threat facing the poultry industry globally. This study was conducted to investigate the level of Salmonella contaminations and determine the resistance pattern of isolates obtained from selected poultry farms in Kwara State, a transition state between southern and northern regions of Nigeria. A total of 900 samples were collected between January and August 2017, from the poultry environment, apparently including healthy and dead birds. Salmonella was isolated and identified using standard bacteriological methods. All presumptive Salmonella isolates were serotyped and tested for antimicrobial susceptibility using 11 different antimicrobials. A total of 58 (6.4%) Salmonella isolates were obtained, and the isolation rate was only statistically significant ( p < 0.05) in live birds. The isolates comprised of 13 serovars. The three predominant serovars, Salmonella enterica ser. 6.7:d:- (29.0%), Salmonella Agama (28.0%) and Salmonella Typhimurium (16.0%), were isolated from all three sample types. Rare serovars like Salmonella Albany, Salmonella Colindale, Salmonella Istanbul, Salmonella Larochelle, Salmonella Nigeria and Salmonella Orion were also isolated in this study. A high frequency of resistance was generally observed with all the isolates exhibiting a total of (100%) resistance to ampicillin, cefotaxime and ceftazidime. This study documents the first predominant isolation of S. enterica ser. 6.7:d:- and S. Agama from chickens. It also documents the high frequency of fluoroquinolone and cephalosporins resistance of the isolates indicating the presence of selective pressure in the environment. Controls and targeted interventions against Salmonella and the frequent occurrence of antimicrobial resistance in chickens should be initiated to prevent the spread of this organism.

Therefore, this study was conducted to throw light over the isolation, identification and characterization of Salmonella species in duckling farms at Kaliobia Governorate, which may provide beneficial information for the development of the duck industry and public health.…”

This study was conducted on 21 commercial duckling farms (1-20 days old) inspected to show Salmonella infection in different localities at Kaliobia Governorate. Samples were taken from diseased ducklings and freshly dead for bacteriological examination which resulted in, 94 samples were positive from 630 isolates, where 28 isolates from 33 diseased ducklings and 66 isolates from 72 freshly dead ducklings. Three serogroups of Salmonella were obtained by serological identification (Salmonella Typhimurium, Salmonella Enteritidis and Salmonella Blegdam). The antibiotic sensitivity tests for the isolated strains showed multiple antibiotic resistances (oxytetracycline; amoxicillin; ampicillin; streptomycin; erythromycin and trimethoprim/ sulphamethoxazol) but gentamycin, norfloxacin and ciprofloxacin are the most effective antibiotic on the isolated Salmonella and can be used for treatment of Salmonellosis in duck farms. PCR results appeared that, invA and stn genes were detected in all studied Salmonella isolates; pefA gene was detected in four out of five studied isolates but sefC gene was detected in two isolates only. Finally, isolated Salmonellae are virulant pathogens responsible for disease in ducklings resulting in high mortality and morbidity, gentamycin, norfloxacin and ciprofloxacin are the most proper antibiotics used for treatment of Salmonellosis in duck farms.
