This study aimed to illustrate the potential role of wild migratory quails in the epidemiology of some zoonotic pathogens in Egypt. Ninety four apparently healthy migratory quails were collected from public markets after being trapped during hunting season from the North Sinai. Oral, cloaca and organs (liver, lung and heart) swabs were collected for bacteriological and viral examination. Salmonella spp. isolates, revealed multi-drug resistance pattern and high sensitivity to enrofloxacin, nitrofuranation and ofloxacine. Parasitological examination revealed that 35 (37.2%) quails were infected with chewing lice (Phithiraptera spp.). Intestinal infection with Heterakis spp. and/or Ascarida spp. Was detected in 27 (28.7%) quails. All quails were negative for avian influenza virus by direct detection by Rt-PCR for oral and cloaca swabs followed by inoculation in embryonated chicken eggs. In conclusion, the migratory quails might play a potential role in dispersion of zoonosis in Egypt.

“…Although raptors (i.e., Falconiformes and Strigiformes) and birds from the orders Columbiformes or Passeriformes are the main bird species admitted in WRCs in Europe (25,(34)(35)(36)(37), seabirds (i.e., bird species with a life history linked to the marine environment) from the Anseriformes, Charadriiformes, Procellariformes, and Suliformes can also be taken into care, for instance, in connection with oil spills. In such disaster situations, seabirds can be admitted by hundreds or thousands (38)(39)(40), leading to overcrowding, close contact with the veterinary and/or nursing staff and an elevated risk of stressinduced chlamydial shedding.…”

“…In such disaster situations, seabirds can be admitted by hundreds or thousands (38)(39)(40), leading to overcrowding, close contact with the veterinary and/or nursing staff and an elevated risk of stressinduced chlamydial shedding. Until now, only a few studies about the shedding of Chlamydiaceae by seabirds admitted to WRCs have been published (25,34,35). Consequently, studying the epidemiology of chlamydial infections in seabirds represents a major challenge both in terms of biodiversity conservation and public health issues.…”

f Birds are the primary hosts of Chlamydia psittaci, a bacterium that can cause avian chlamydiosis in birds and psittacosis in humans. Wild seabirds are frequently admitted to wildlife rescue centers (WRC) at European Atlantic coasts, for example, in connection with oil spills. To investigate the extent of chlamydial shedding by these birds and the resulting risk for animals in care and the medical staff, seabirds from a French WRC were sampled from May 2011 to January 2014. By use of a quantitative PCR (qPCR), 195 seabirds belonging to 4 orders, 5 families and 13 species were examined, of which 18.5% proved to be Chlamydiaceae positive. The highest prevalence of shedders was found in northern gannets (Morus bassanus) (41%), followed by European herring gulls (Larus argentatus) (14%) and common murres (Uria aalge) (7%). Molecular characterization and phylogenetic analysis of qPCR-positive northern gannet samples revealed two variants of a strain closely related to C. psittaci. In European herring gulls and in one common murre, strains showing high sequence similarity to the atypical Chlamydiaceae-like C122 previously found in gulls were detected. Our study shows that seabirds from the northeastern Atlantic Ocean carry several chlamydial organisms, including C. psittaci-related strains. The staff in WRCs should take protective measures, particularly in the case of mass admissions of seabirds.

“…Wildlife, animals free to roam, may be a significant reservoir for zoonotic pathogens (4,16,18,35,37,39). Wild birds are known to carry and transmit over 40 diseases to humans and livestock (13,24,34,35,36,49). Recent studies have also highlighted wild birds as sources of pathogens associated with human disease (5,9,22,50).…”

“…Therefore, avian wildlife are a potential source for spreading infectious diseases to livestock year round. Escherichia coli O157:H7, Salmonella, Listeria, and Campylobacter are among pathogens that have been recognized as being carried by avian wildlife and are potentially pathogenic to humans and livestock (5,13,35,43,49,50).

Escherichia coli, Salmonella, and Mycobacterium avium subsp. paratuberculosis in Wild European Starlings at a Kansas Cattle Feedlot

The prevalence of Escherichia coli, Salmonella spp., and Mycobacterium avium subsp.paratuberculosis isolated from the feces of wild European starlings (Sturnus vulgaris) humanely trapped at a feedlot in central Kansas was assessed. All E. coli and Salmonellaisolates recovered were tested for antimicrobial susceptibility using National Antimicrobial Resistance Monitoring System panels and the E. coli isolates were classified as to their content of genes associated with pathogenic E. coli of birds and cattle, including cvaC, iroN2, ompTp, hlyF2, eitC, iss, iutA, ireA, papC, stxI, stxII, sta, K99, F41, and eae.Escherichia coli O157:H7 and Mycobacterium avium subsp. paratuberculosis were not detected and Salmonella was isolated from only three samples, two of which displayed antimicrobial resistance. Approximately half of the E. coli isolates were resistant to antimicrobial agents with 96% showing resistance to tetracycline. Only one isolate was positive for a single gene associated with bovine pathogenic E. coli. An interesting finding of this study was that 5% of the E. coli isolates tested met the criteria established for identification as avian pathogenic E. coli (APEC). Thus these findings suggest that starlings are not a significant source of Salmonella spp., Mycobacterium avium subsp.paratuberculosis, E. coli O157, or other shiga toxin-producing E. coli in this feedlot. However, they may have the potential to spread APEC, an important pathogen of poultry and a potential pathogen to human beings. SUMMARY.
