“…The most frequently isolated serotype was S. Kentucky. Other studies in the USA [33,34] have reported a lower prevalence (8/342, 2%, and 2/375, 0.5%) of Salmonella in free-living waterfowl. Furthermore, in Chile, a prevalence of 6% was reported by Fresno et al [35].…”

“…Al Faruq et al [11] recorded that the resistance rate of KF was 30-67% from Asian pied starling and house crows that were caught in Bangladesh. Grigar et al [34] isolated S. Thompson and Salmonella Braenderup, and both isolates were susceptible to all antimicrobial agents tested. Fasaei and Tamai [1] recorded that 42.8% of Salmonella isolated from wild animals in Iran were resistant to AML.…”

Background and Aim: Wild birds can carry a number of potential human and animal pathogens. These birds can intrude into human habitats giving the opportunity to transmission of such infection. Therefore, the current study was designed to investigate the role of crows and waterfowls as vectors of Salmonella and Listeria monocytogenes and to compare cultivation methods with direct polymerase chain reaction (PCR) for the detection of infection. Materials and Methods: A total of 200 fecal dropping samples were collected. Salmonella was cultivated by three step method (Universal Pre-enrichment Broth [UPB], Rappaport-Vassiliadis Broth, and Xylose Lysine Desoxycholate agar). The recovered isolates were characterized by biotyping, serotyping, and PCR detection of enterotoxin (stn) gene. The antibiogram pattern of isolates against a panel of 8 antibiotics was recorded. L. monocytogenes was cultivated on UPB, then on Listeria Oxford Agar and Listeria CHROMagar. The recovered isolates were characterized by biotyping and PCR detection of listeriolysin (hylA) gene. Results: The percentages of Salmonella infection in crows and waterfowls were 10 and 20, respectively. The most frequently recovered serovars were Typhimurium, Potengi, Enteritidis, and Kentucky. Antimicrobial susceptibility analysis of Salmonella isolates showed that the resistance rates for gentamicin were the highest (92%), followed by amoxicillin (88%) and cefixime (60%). Resistance to 8 antibiotics was recorded in 60% (15/25) of Salmonella isolates. The percentages of L. monocytogenes infection in crows and waterfowls were 1.3 and 2, respectively. Direct PCR applied to UPB revealed that 12% and 3% of samples were positive for Salmonella and L. monocytogenes, respectively, and there was no significant difference between direct PCR and cultivation method for the detection of infection. Conclusion: The present findings indicate that wild birds can harbor zoonotic enteric pathogens and this necessitates monitoring the epidemiologic status of these pathogens among wild birds and humans and applying the appropriate intervention measures to prevent the spread of infection.

“…Concomitant disease is discussed to increase the susceptibility to salmonellosis 6 . Infections with Salmonella have also been reported for various aquatic birds, 6, 15–18 including an outbreak in a heron colony involving six different heron species 19 . For both Salmonella positive passerine birds, a greenfinch and a house sparrow, no clinical history or age was noted.…”

Background Salmonella are bacteria of the family Enterobacteriaceae with a wide host range. Infection in birds causes subclinical disease to mass mortality events. Wild birds may act as healthy carriers posing a hazard to livestock and humans. The present study investigated the occurrence of Salmonella in wild birds admitted to a rehabilitation centre in order to assess the exposure of the staff to this zoonotic pathogen. Methods Faecal swabs of 552 avian patients (68 species) were collected over the course of 12 months. Each sample was propagated in enrichment broth and subsequently incubated on a RAPID' Salmonella plate. Salmonella isolates were serotyped, and antimicrobial susceptibility testing was performed. Results Six Salmonella enterica subsp. enterica serovar Typhimurium ( S . Typhimurium) and 1 S . Schleissheim were detected; all were pansusceptible to the antibiotics tested. Conclusion Despite the low positive rate in the tested population, the authors recommend applying protective equipment and hygiene measures when handling wild birds.

“…However, many reports on Salmonella in poultry mainly focused on chickens and turkeys ( Barrow et al., 2012 ). Recent studies have shown that waterfowl such as geese and ducks are also important sources of Salmonella ( Grigar et al., 2017 ). Salmonella infection in geese and ducks is a recessive infection, but sometimes it can also have serious clinical symptoms with high mortality, and become the hidden danger of human health ( Martelli et al., 2017 ).…”

This study investigated the prevalence of Salmonella and the molecular typing of all isolates in a goose production chain including hatchery, farm, slaughterhouse, and market. A total of 350 Salmonella isolates was detected from 1,030 samples, and 13 serotypes were recovered. The highest Salmonella contamination frequency was observed at the hatchery, which 51.8% (188/363) of samples were Salmonella positive. S . Potsdam and S . Typhimurium were the 2 most common serotypes. S . Potsdam was most frequently found in the hatchery, while S . Typhimurium was widely distributed in the goose production chain. In general, the antibiotic resistance of Salmonella isolates is low, which isolates from the market is comparatively higher than from other production links indicating a possibility of Salmonella cross-contamination in the market. By the multilocus sequence typing ( MLST ) analysis, 7 different ST types were identified. ST2039 was the most common ST type, which was mostly found from S . Potsdam isolates in hatchery indicating that S . Potsdam might have been long existed in hatchery. The pulsed-field gel electrophoresis ( PFGE ) analysis of S . Potsdam indicated that S . Potsdam could be transmitted along the production chain. The PFGE analysis of S . Typhimurium showed that PFGE pattern 29 (PF29) was distributed in hatchery, and also in farm and from humans indicating the risk of S . Typhimurium transmitting to humans by the food supply chain. Our study provided the evidence of Salmonella cross-contamination in the slaughterhouse and the retail market of goose production chain, and specific serotypes existed for a long time at a particular production link. The spread of Salmonella along the production chain, might cause harm to humans through cross-contamination. Further studies would be needed to control the Salmonella contamination in hatchery and prevent the transmission of the pathogen during the goose production.
