“…However, our estimate is lower than findings reported from West Bengal in India (15%; n = 40, Samanta et al., 2014), and from Iran (5.8%; n = 85) following testing of 422 cloacal swab samples from 35 backyard flocks (Jafari et al., 2007). Our findings are in fact similar to those in Paraguay (3.5%; n = 400) of 50 backyard flocks (Leotta et al., 2010), and the central region of Saudi Arabia (2.2%) obtained from broiler parent flocks (Saad et al., 2007). Notwithstanding, the aforementioned comparisons should be regarded with caution given various differences in the techniques used for isolation, limited sampling areas (as seen in the study from Paraguay, which used a relatively small sample size, and the study from Iran), and differences in the population dynamics of dominant Salmonella serovars in each country.…”

Salmonella in native “village” chickens (Gallus domesticus): prevalence and risk factors from farms in South-Central Peninsular Malaysia

et al. 2019

Village chicken or Ayam Kampung, common to Southeast Asian countries, has always been regarded as superior in comparison to commercial broiler chicken in terms of wholesomeness and health benefits. The current study investigates the prevalence and risk factors of Salmonella among village chicken flocks from the central and southern states of Peninsular Malaysia. A total of 35 village flocks were sampled from Selangor (n = 19), Melaka (n = 10), Johor (n = 4), and Negeri Sembilan (n = 2). In total, 1,042 samples were collected; these included cloacal swabs (n = 675), eggs (n = 62), pooled drinking water (n = 175), pooled feeds (n = 70), and pooled flies (n = 60). Isolation of Salmonella from cloacal swabs, poultry drinking water, and feeds was carried out according to the protocols and recommendations of the World Organization for Animal Health (OIE) terrestrial manual. The prevalence of Salmonella at an individual bird-level was 2.5% (17/675, 95% CI: 1.6 to 4.0). All eggs screened were negative; in the case of environmental samples, however, Salmonella was detected in 5.14% (9/175), 7.14% (5/70), and 5.0% (3/60) for water, feed, and flies, respectively. A total of 34 isolates and 8 Salmonella serotypes were identified. Weltevreden (20.6%) was the most common, followed by Typhimurium and Agona (17.6%), Albany and Enteritidis (8.8%), Molade (5.9%), Corvallis and Schleissheim (2.9%), and others grouped as Salmonella spp. (11.8%). Multivariable logistic regression models revealed that Salmonella positivity among flocks could be strongly predicted by storage of feeds (uncovered feeds; OR = 10.38; 95% CI: 1.25 to 86.39; p = 0.030) and uncovered water tanks (uncovered tank; OR = 6.43; 95% CI: 1.02 to 40.60; p = 0.048). The presence of Salmonella in village chickens in the study area was lower than that of commercial chickens in Malaysia.

“…Xie et al [19] reported that 5.40% of Salmonella isolated from eggs in Guangdong, China. Previous workers, who found 2.98% [20] and 3.5% [21] Salmonella prevalence in Ethiopia and Paraguay, reported lower Salmonella isolation rates. In this study, Salmonella prevalence was recorded 8.33%, 13.33%, and 1.67% in farms, whole sellers and retailers, respectively that agreed with Singh et al [22].…”

Salmonella is one of the most common zoonotic bacteria that cause foodborne illness in humans. An investigation was conducted to determine the prevalence and antibiotic susceptibility patterns of Salmonella isolates from chicken eggs in the Naogaon district, Bangladesh. Salmonella was isolated from cultures on different selective-differential media and further identified by biochemical tests. Antibiogram study was done by the disk diffusion method. The overall prevalence of Salmonella was recorded as 7.78%, whereas 5.56% was on eggshell surfaces and 2.22% was in egg contents. The Salmonella prevalence was 8.33%, 13.33% and 1.67% in chicken eggs from layer farms, whole sellers and retailers, respectively. Salmonella isolates were found 50.0% to 85.71% sensitive to chloramphenicol, gentamycin, ciprofloxacin, and ceftriaxone. Resistance against gentamycin, chloramphenicol, and ampicillin was found significant ranging from 21.43% to 71.42%. The highest resistance was found in amoxicillin (92.86%). The present study proposes that chicken eggs are a potential reservoir of multidrug-resistant Salmonella. Antibiotic-resistant Salmonella will pose a problem to treat Salmonella infection in humans. Thus, the aim of this study is to assess the risk of Salmonella resistance in chicken eggs.

“…The seroprevalence rate of Salmonella in backyard chicken was moderate (16%) in Argentina (Xavier et al, 2011). However, a lower isolation rate was reported by (Jafari et al, 2007, Namata et al, 2009and Leotta et al, 2010 who found 5.8, 6, and 3.5% as Salmonella prevalence in backyard chicken flock in Iran, Belgium, and Paraguay, respectively. In a study in backyard birds (RIR breed) in India (West Bengal), the isolation rate of Salmonella was 15%.…”
