The study was aimed at evaluating the prevalence of enteropathogenic bacteria (i.e. Campylobacter spp., shigatoxin-producing Escherichia coli, Salmonella spp.) in common quail (Coturnix coturnix). To achieve this goal, 70 common quails were collected during the hunting season in the Campania region (southern Italy). From each bird, cloacal swab samples were collected and subjected to culture methods, polymerase chain reaction and serotyping. The results of the present study showed a prevalence of 21.4% and 5.7% for Campylobacter spp. and shigatoxin-producing E. coli, respectively. In contrast, no Salmonella spp. was isolated. These findings show that common quail, as migratory birds, may constitute an environmental carrier of these pathogens representing a source of infection for other birds, livestock and humans.

“…Another study conducted in Iran recorded 15.55% prevalence rate of Salmonella in pigeons (Akbarmehr, 2010). Higher prevalence rate of Salmonella recorded in this study might be the effects of bird density, increased success of fecal-oral transmission, strain differences of the birds, immune status of the flocks and geographical variation (Carraminana et al, 1997;McCrea et al, 2006). Salmonella is known to cause food-borne infection in humans and estimated to cause 1.3 billion cases of gastroenteritis and 3 million deaths worldwide (Bhunia, 2008).…”

“…This study recorded the highest prevalence of Salmonella at the live bird markets (40.28%) as compared to farms (20%) and villages (30%). McCrea et al (2006) reported the lowest prevalence rate of Salmonella in squabs on farm (1.3%) compared to post transport squabs (2.1%) and carcass swabs of squabs (23.8%) in processing plants. Lack of proper hygiene and sanitary practices, cross contamination with other species of birds and overcrowding might be responsible for the highest prevalence of Salmonella in pigeons at the live bird markets.…”

Prevalence and Antibiogram Profiles of Salmonella Isolated from Pigeons in Mymensingh, Bangladesh

A B S T R A C TThis study was undertaken to determine the prevalence of Salmonella spp. in apparently healthy pigeons at the live bird markets, farms and villages in the Mymensingh district of Bangladesh. Cloacal swabs (n = 36), foot pads (n = 36) and feces (n = 40) of pigeons were collected aseptically and inoculated onto various culture media for isolation of Salmonella. Identification of Salmonella from culture positive samples was performed by cultural characteristics, Gram's staining and biochemical tests. The prevalence of Salmonella in cloacal swabs, foot pads and feces was 22.22%, 58.33% and 27.50%, respectively. The overall prevalence of Salmonella in pigeons was 35.71%. Pigeons at live bird markets, farms and villages showed a 40.48%, 20% and 30% prevalence of Salmonella, respectively. Antibiotic sensitivity tests of the Salmonella was performed by the disc diffusion method against 10 randomly used antibiotics. The highest rate of resistance was found with amoxicillin (90%) followed by ampicillin (80%), erythromycin (80%) and tetracycline (60%). The highest rate of sensitivity was recorded to ciprofloxacin (80%) followed by sulphamethoxazole (70%), chloramphenicol (60%), kanamycin (60%), gentamicin (60%) and nalidixic acid (60%). Data from this study suggest that pigeons carry multi-drug resistant Salmonella which can be transferred to humans through direct contact or the food chain and could cause a potential public health hazard.

“…Enhanced biosecurity measures may be particularly important at specific times of the year. Seasonality was an observed risk factor or a confounder of risk in many of the publications reviewed (5,7,11,25,35,40,41,44,46,48,53,54,65,68,69,77). The seasonal risk peak generally occurs in late summer/ early autumn, but the timing, extent, and sharpness of this peak can vary between countries and may be related to the latitude of the country (22).…”

The prevention and control of Campylobacter colonization of poultry flocks are important public health strategies for the control of human campylobacteriosis. A critical review of the literature on interventions to control Campylobacter in poultry on farms was undertaken using a systematic approach. Although the focus of the review was on aspects appropriate to the United Kingdom poultry industry, the research reviewed was gathered from worldwide literature. Multiple electronic databases were employed to search the literature, in any language, from 1980 to September 2008. A primary set of 4,316 references was identified and scanned, using specific agreed-upon criteria, to select relevant references related to biosecurity-based interventions. The final library comprised 173 references. Identification of the sources of Campylobacter in poultry flocks was required to inform the development of targeted interventions to disrupt transmission routes. The approach used generally involved risk factor-based surveys related to culture-positive or -negative flocks, usually combined with a structured questionnaire. In addition, some studies, either in combination or independently, undertook intervention trials. Many of these studies were compromised by poor design, sampling, and statistical analysis. The evidence for each potential source and route of transmission on the poultry farm was reviewed critically, and the options for intervention were considered. The review concluded that, in most instances, biosecurity on conventional broiler farms can be enhanced and this should contribute to the reduction of flock colonization. However, complementary, non-biosecurity-based approaches will also be required in the future to maximize the reduction of Campylobacter-positive flocks at the farm level.
