Survey of Salmonella serovars in broilers and laying breeding reproducers in east of Algeria

Abstract

Background: Avian salmonellosis affects the poultry industry in underdeveloped and in developed countries. The aim of this study was to identify the most common Salmonella serovars in broilers and laying breeding reproducers in Eastern Algeria according to the ISO 6579 method. Methodology: A total of 294 samples were obtained from two flocks of 10,000 broilers and laying breeding reproducers. Samples included livers and spleens, drag swabs of bottom boxes of young chickens, cloacal swabs, and faecal samples of chickens. Additional samples were also taken from water, feed and dusty surfaces. Results and conclusions: Only the cloacal swabs, poultry faeces and samples from dusty surfaces were positive for Salmonella Typhimurium and Salmonella Livingstone with a detection rate of 12% and 1.6% respectively. The results showed evidence of legislative failure regarding biosafety within the poultry industry in the area of Batna, Eastern Algeria.

Survey of Salmonella Contamination in Chicken Layer Farms in Three Caribbean Countries

“…The overall frequency of isolation of Salmonella from the cloacae of laying birds was relatively low (0.9%) in these three countries, which was considerably lower than the range (4 to 12%) reported for other countries (3,16).…”

“…Therefore, the increase in horizontal transmission of Salmonella in in Trinidad and Tobago appears to be real. Reports elsewhere have documented contamination rates of eggshells at 0 to 34% (3,6,28).…”

“…The frequency of isolation of Salmonella reported elsewhere has ranged from 4 to 12% in layer birds (3,16), from 0.95 to 33.3% for layer farm environments or litters (6,34), from 12.6 to 19.2% for imported day-old chicks (6,31), from 0.35 to 1.24% for hatching eggs (6), and from 13 to 29% for hatcheries (13,35). Rodents also have been documented as a potential source of Salmonella in layer farm environments (22,23,38).…”

Prevalence and Antimicrobial Resistance of Salmonella Isolated from Meat and Meat Products in Algiers (Algeria)

“…In Algeria, Salmonella Enteritidis was the most frequently isolated from various poultry farm samples (Aboun et al, 2003) and particularly from laying-hen samples (Bouzidi et al, 2012). In poultry feces and litter, only two serovars were identified: Salmonella Typhimurium and Salmonella Livingstone, with a detection rate of 12% and 1.6%, respectively, while no Salmonella was found in spleen or liver (Ammar et al, 2010).…”

“…The few works undertaken providing data on Salmonella focused on the isolates from clinical or animal sources, particularly from broiler and/or laying-hen flocks (Boudilmi and Chalabi, 1997;Aboun et al, 2003;Elgroud et al, 2009;Ammar et al, 2010;Bouzidi et al, 2012). In other African countries, the prevalence and antimicrobial resistance of Salmonella in various foodstuffs are well documented (Guellouz and Ben Aissa, 1995;Nyeleti et al, 2000;Molla and Mesfin, 2003;Ejeta et al, 2004;Van Nierop et al, 2005;Bada-Alambedji et al, 2006;Stevens et al, 2006;Ben Aissa et al, 2007).…”
