“…The isolation rate of Salmonella serovars in this study correlates with earlier study by Muhammad et al (2010) which reported isolation rate of 9.0 % from farms in Jos, Plateau state, Nigeria. It is however higher than 2.8 % reported in Caribbean countries (Adesiyun et al, 2014) Salmonella Typhimurium was the most frequent isolated serovar and this agree with previous work which also reported this serovar as one of the common serovars isolated from poultry in Nigeria (Orji et al, 2005). The isolation of invasive Salmonella such as serotype Typhimurium and other pathogenic salmonellae in this study highlights the risk of health hazards to consumers as contaminated poultry and poultry products may serve as source of infection to human food chain (Doaa, 2013).…”

“…In the current study, size of farm was found to have a significant effect only on the frequency of resistance to kanamycin across the three countries and within Trinidad and Tobago; this may reflect differences in management systems and the use of antimicrobial agents, as reported elsewhere (4,32).…”

“…Standard methods were used to process the samples collected and to isolate Salmonella (4,6,23). Briefly, samples were preenriched in buffered peptone water (Oxoid, Ltd., Hampshire, England) for 18 to 24 h at 37°C and then were enriched in tetrathionate broth (Oxoid) and in Rappaport-Vassiliadis broth (Oxoid) incubated for 18 to 24 h at 37 and 42°C, respectively.…”

“…The procedures used to isolate Salmonella serovars from the samples were described earlier (4). Briefly, the selective broths (tetra thionate and Rappaport-Vassiliadis) were subcultured onto xyloselysine deoxycholate agar and brilliant green agar (Oxoid) and were incubated aerobically at 37°C for 24 h. All colonies suggestive of Salmonella serovars on the selective agar were purified on blood agar plates (Oxoid) at 37°C for 24 h and then were subjected to biochemical tests, including triple sugar iron agar, urea, citrate, methyl red, sulfide-indole-motility medium, o-nitrophenyl-p-Dgalactopyranoside, and lysine iron agar (Oxoid) (6,23).…”

This investigation determined the frequency of resistance of 84 isolates of Salmonella comprising 14 serotypes recovered from layer farms in three Caribbean countries (Trinidad and Tobago, Grenada, and St. Lucia) to eight antimicrobial agents, using the disc diffusion method. Resistance among isolates of Salmonella was related to the country of recovery, type of sample, size of layer farms, and isolate serotype. Overall, all (100.0%) of the isolates exhibited resistance to one or more of seven antimicrobial agents tested, and all were susceptible to chloramphenicol. The resistance detected ranged from 11.9% to sulphamethoxazole-trimethoprim (SXT) to 100.0% to erythromycin. The difference was, however, not statistically significant (P = 0.23). Across countries, for types of samples that yielded Salmonella, significant differences in frequency of resistance were detected only to SXT (P = 0.002) in Trinidad and Tobago and to gentamycin (P = 0.027) in St. Lucia. For the three countries, the frequency of resistance to antimicrobial agents was significantly different for ampicillin (P = 0.001) and SXT (P = 0.032). A total of 83 (98.8%) of the 84 isolates exhibited 39 multidrug resistance patterns. Farm size significantly (P = 0.032) affected the frequency of resistance to kanamycin across the countries. Overall, among the 14 serotypes of Salmonella tested, significant (P < 0.05) differences in frequency of resistance were detected to kanamycin, ampicillin, and SXT. Results suggest that the relatively high frequency of resistance to six of the antimicrobial agents (erythromycin, streptomycin, gentamycin, kanamycin, ampicillin, and tetracycline) tested and the multidrug resistance detected may pose prophylactic and therapeutic concerns for chicken layer farms in the three countries studied.

RÉSUMÉLa précarité des systèmes d'élevage avicole en Afrique de l'Ouest peut favoriser l'introduction de germes pathogènes dans les élevages. Or, les fumiers de volaille sont très utilisés dans le maraîchage au Bénin. Par conséquent, le transfert de germes des fumiers vers les produits maraîchers est à craindre. L'objectif de cette étude était d'explorer les pratiques d'élevage avicole dans le département de l'Atlantique (Sud-Bénin). Au total, 78 fermes avicoles ont été visitées. Un questionnaire a été administré aux producteurs. La plupart d'entre eux (82,1%) ont rapporté qu'ils se lavent toujours les mains avant d'entrer dans les poulaillers. Sur les fermes disposant de pédiluves, 15,4% des producteurs ont avoué ne pas toujours y passer avant d'accéder aux poulaillers. Un seul producteur a rapporté qu'il ne fait pas la décontamination terminale des bâtiments. L'analyse du fumier prélevé sur l'une des fermes a révélé la présence de quantités très élevées de germes aérobies mésophiles d'Escherichia coli, de Clostridium perfringens et de coliformes thermotolérants. Ces résultats microbiologiques montrent que les pratiques d'hygiène en aviculture sont encore peu satisfaisantes au Bénin. © 2015 International Formulae Group.

Poultry farming practices in South-Benin (West Africa) and impacts on the manures hygiene ABSTRACTIn general, the poultry farming systems in West Africa are less sophisticated. These systems can be sources of carrying out of pathogens to the farms. But, in Benin Republic, poultry manures are widely used in market gardening. So, the transfer of pathogens from manures to vegetables is worrisome. This research aimed M. A. BOKO et al. / Int. J. Biol. Chem. Sci. 9(6): 2740-2753, 2015 2741 at investigating the poultry farming practices in the Atlantic division (South-Benin). In total, 78 poultry farms were visited. A questionnaire was handed out to the producers. Most of them (82.1%) reported that they always wash their hands before entering poultry houses. On the farms where footbaths were present, 15.4% of producers declared that they do not always pass through it before entering poultry houses. Only one producer reported that he does not do the final decontamination of the houses. Analysis of the manure taken from one of the farms showed very high amounts of aerobic mesophile bacteria, of Escherichia coli, of Clostridium perfringens and thermotolerant coliforms. These microbiological results show that satisfying hygiene practices in poultry farming are still lacking in Benin.
