“… 13 , 14 , 20 , 21 There has been but a single report of Campylobacter in parrots; during a disease outbreak in Peru. 22 We have investigated the normal gut microbiota of wild and captive scarlet macaws and failed to detect Campylobacter . 23 Likewise, Campylobacter has not been detected in the normal microbiota of the cockatiel.…”

Psittacine proventricular dilatation disease (PDD) is a neurological disease caused by parrot bornaviruses. A competing theory suggests that intestinal colonization by Campylobacter species may also be a potential cause of PDD or that their presence may be required for disease development. This theory proposes that PDD results from the activities of antiganglioside antibodies on enteric neurons in a manner similar to the pathogenesis of Guillain–Barré syndrome in humans. We therefore cultured feces from domestic chickens as well as from multiple parrot species to determine whether Campylobacter spp. could be detected in the latter. We failed to detect Campylobacter in a flock of cockatiels known to be highly susceptible to experimental parrot bornavirus-induced PDD. Even in naturally infected psittacines suffering from clinical PDD, no Campylobacter species were detected. Conversely, Campylobacter was readily cultured from domestic poultry samples and confirmed by using matrix-associated laser desorption ionization mass spectroscopy/real-time polymerase chain reaction. We conclude that not only are Campylobacter infections of psittacines uncommon, but also that infection by Campylobacter species is not related to the etiology of PDD.

The aim of this investigation was to study the frequency of visceral larva migrans (VLM) granulomas in autopsies at a Children's Reference Hospital in Vitoria, ES Brazil, where anti-Toxocara antibodies are frequently detected in the serum of children admitted at the hospital. Two liver fragments from 310 autopsies of children aged between 1 and 15 years were paraffin embedded, and sections were stained with hematoxylin and eosin and submitted to detection of Toxocara antigens using a rabbit anti-Toxocara serum. Among the 24 cases with granulomatous lesions, ten had eosinophil-rich granulomas positively stained with the anti-Toxocara serum. Some were typical epithelioid granulomas, with a positive reaction in multinucleated giant cells, epithelioid cells, or necrotic debris. The results showed that VLM granulomas are the most frequent granulomatous hepatitis in children in our county. This agrees with the high prevalence of anti-Toxocara antibodies in the serum of children admitted to the Children's Reference Hospital. The 3.2% frequency of liver VLM granulomas in autopsies is less than the 30-39% frequency of positive serology in these children, probably reflecting the low larval burden in infected children.
