“…In previous studies, S. arizonae has been isolated mainly in turkeys where it is associated with acute septicaemia of poults (Crespo et al, 2004), but may cause infections in chickens (Silva et al, 1980) that are possibly reared closely together with infected turkeys. Although turkey production is common especially in areas where RFR and SSC chicken farming is practiced, Data presented as n (%).…”

A study was carried out to determine the distribution and antimicrobial susceptibility profiles of Salmonella serovars from chickens from large-scale commercial (LSC), small-scale commercial (SSC), and rural freerange (RFR) farms of Zimbabwe. Pooled cloacal swabs were collected for culture and isolation of Salmonella spp. A chi-square test was used to assess distribution differences of salmonellas among the farming sectors. Approximately 10% (283/2833) of the swabs were positive for Salmonella enterica, with only subspecies enterica (98.6%) and arizonae (1.4%) being detected. The prevalence of S. enterica varied significantly (PB0.05) among areas, with Harare (27.8%) and Buhera (1.3%) recording the highest and the least prevalence, respectively. S. enterica was only isolated from LSC and SSC farms, with the former having a significantly (PB0.001; x 2 0155.3) higher prevalence than the latter. S. arizonae was only isolated from the SSC farms while none were obtained from the RFR farms. The serovars isolated were Salmonella Enteritidis (72.8%), Group C (20.1%), Group B (4.2%), Salmonella Typhimurium (1.1%) and Salmonella Gallinarum (0.4%). S. Enteritidis predominated in the urban/periurban areas. Approximately 26% (53/206) of S. Enteritidis isolates were resistant to one or more antimicrobial agents. Resistance to tetracycline was the most common, while no resistance was detected for furazolidone, neomycin and trimethoprimsulfamethoxazole. There were 12.1% multi-drug-resistant S. Enteritidis isolates, and the resistance to ampicillin/kanamycin was predominant. The identification of multi-drug-resistant S. Enteritidis is of public health concern. Thus, stringent control of S. Enteritidis will reduce the public health risk of human salmonellosis.

“…S. enterica subsp. arizonae is associated with acute septicaemia (arizonosis) in turkeys (Crespo et al, 2004) and occasionally in chickens (Silva et al, 1980) but it is widely distributed in reptilian and mammalian species (Oros et al, 1998;Ramsay et al, 2002).…”

“…For instance, Salmonella enterica subsp. arizonae was associated with disease in broilers (Silva, Hipolito, & Grecchi, ). Added to this, this pathogen has been reported associated with disease in people suffering immune system alterations (Noskin & Clarke, ) but also in children due to the contact with reptiles kept as pets (Kolker, Itsekzon, Yinnon, & Lachish, ).…”

Scavenger birds exploiting rubbish dumps: Pathogens at the gates

Different bacteria are present in rubbish dumps used as food resources by various bird species. Birds may be good indicators of the presence of zoonotic diseases in these sites since they can be infected with zoonotic pathogens by foraging on organic waste, and can also act as carriers. We studied if foraging in rubbish dumps increases the occurrence of Salmonella spp. and Chlamydia psittaci in American black vultures (Coragyps atratus, hereafter black vultures) from northwest Patagonia. We compared these pathogens isolated from or detected in cloacae and oropharynx swabs in two different groups of black vultures: individuals trapped in (a) the Patagonian wild steppe and (b) in a rubbish dump. We found that black vultures are colonized by Salmonella spp. (particularly Salmonella enterica serotypes Typhi, Paratyphi A, Salmonella enterica subsp. arizonae) and Chlamydia psittaci. Interestingly, there were differences in the prevalence of Salmonella spp., especially Salmonella Typhi, between individuals foraging in the rubbish dump and the steppe, but not in the prevalence of Chlamydia psittaci. The pathogens isolated from black vultures may impact their health status but could also have health impacts in other bird species and even humans. In fact, Salmonella Typhi can cause severe disease in humans leading to death. Our results are globally relevant given that bacterial infections from rubbish dumps may affect different species exploiting these sites around the world. There is a need to better control pathogens in rubbish dumps to avoid the risk of infecting wildlife, which could act as potential dispersers and reservoirs of these pathogens.

“…It has been described in association with Marek's disease (Smith et al, 1974), avian encephalomyelitis or Salmonella arizonae infection (Silva et al, 1980). Cataracts have also been associated with vitamin E deficiency in turkeys (Ferguson et al, 1956) or as a result of light-induced oxidative stress (Lauber & McGinnis, 1966).…”

“…In domesticated birds, cataracts may develop as a secondary ocular lesion in infectious disease (Ferguson et al, 1956;Smith et al, 1974;Silva et al, 1980). In ducks, ocular lesions are rarely reported and concern only acquired disease (Gilger et al, 1995;Gordus et al, 2002).…”

Ocular opacity, associated with reluctance to move and inability to feed properly, was observed in approximately 1% of all newly hatched females from several related flocks of Mulard ducks. A 5-week follow-up study of 10 1-day-old affected females was performed, and they were compared with 10 control animals. Clinical, ocular and ultrasonographic examinations, and a complete necropsy of two animals per group with histological examination of the eye, were performed weekly. A bilateral immature cortical anterior cataract was diagnosed at ocular examination and confirmed by ultrasonography in affected ducks. Dyscoria was occasionally observed in affected animals. Severe cataract, with Morgagnian globules, severe anterior fibre liquefaction and disorganization were observed by photonic microscopy. No retinal or choroidal lesions were observed. No progression or repair of ultrasonographic and microscopic lesions could be detected during the 5 weeks of examination. The female predisposition for the ocular lesions suggests a congenital sex-linked recessive cataract.
