Fatal traumatic injuries in free-living wild Passeriformes and Psittaciformes birds in Central Brazil, 2006-2018 / Injúrias traumáticas fatais em aves Passeriformes e Psittaciformes no Brasil Central, 2006-2018

Traumatic injuries are a significant cause of death for birds worldwide, as they are at an increased risk of collisions and other injuries due to man-made environments. This study examined the frequency and morphological characteristics of fatal traumatic injuries in endemic and migratory Passeriformes and Psittaciformes from the Cerrado Biome, a biodiverse but threatened area in Brazil. Results showed that fatal traumatic injuries were found in 21.8% of birds (285/1305), mainly in spring and summer, during the birds' reproductive period. The yellow-chevroned parakeet (Brotogeris chiriri) and Passeriformes from the Thraupidae family were the most affected. Nearly 70% of the fatal injuries observed were to the thoracic, pelvic limbs, and skull, and types of fractures and affected bones were thoroughly evaluated. Blunt traumas were one of the most frequent causes of injuries. Injuries affecting the appendicular skeleton and head represented significant causes of traumatic death for Passeriformes and Psittaciformes. The frequency of these fatal injuries has been increasing in recent years, which may be related to the remarkable environmental changes in the Cerrado Biome and jeopardize the survival of many bird species.

As lesões traumáticas são uma causa significativa de morte nas aves em todo o mundo, pois apresentam um risco maior de colisões e outras lesões devido aos ambientes degradados e criados pelo homem. Este estudo examinou a frequência e as características morfológicas das lesões traumáticas fatais em Passeriformes e Psittaciformes endêmicos e migratórios do Bioma Cerrado, uma área com rica biodiversidade, mas ameaçada no Brasil. Os resultados demostraram que as lesões traumáticas fatais foram observadas em 21,8% das aves (285/1305), principalmente na primavera e verão, durante a época reprodutiva das aves. O periquito-do-encontro-amarelo (Brotogeris chiriri) e Passeriformes da família Thraupidae foram as aves mais frequentemente acometidas. Por volta de 70% das lesões fatais observadas foram nos membros torácicos e pélvicos, e crânio, e os tipos de fraturas e ossos afetados foram minuciosamente avaliados. Os traumas contudentes foram as principais causas das lesões. As injúrias que afetaram o esqueleto apendicular e a cabeça representaram as mais importantes causas de morte traumática para Passeriformes e Psittaciformes. A frequência dessas lesões fatais vem aumentando nos últimos anos, o que pode estar relacionado às mudanças ambientais marcantes no Bioma Cerrado e colocar em risco a sobrevivência de muitas espécies de aves.

Use of MALDI-TOF for identification and surveillance of gram-negative bacteria in captive wild psittacines

Abstract Microbiological studies of the sanitary and health status of psittacine birds that will be reintroduced is important in evaluating whether these animals act as carriers of pathogenic agents to other animals and humans. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) is a faster and more accurate method to identify bacteria than conventional microbiology methods. The aim of this study was to evaluate the health status of psittacines housed in captivity, by assessment of Gram-negative bacteria from fecal microbiota through MALDI- TOF MS identification. The results indicate high frequency of Gram-negative bacteria in feces (96.5%), especially from the Enterobacteriaceae family (88.7%). The most prevalent bacteria were Escherichia coli (39.0%), Proteus vulgaris (12.2%), Klebsiella spp. (12.1%) and Raoultella ornithinolytica (8.7%). Proteus hauseri, Citrobacter spp., Morganella morgannii, Providencia rettgeri, Enterobacter spp. and Escherichia hermannii were isolated with lower frequency. . All these agents are potentially pathogenic for parrots and can cause systemic infections in other animals and humans. These findings reinforce that MALDI- TOF MS proved to be a rapid and accurate method of identification of the microorganism and evaluation of the health status of psittacines, providing relevant data to assist decision-making regarding the sanitary protocols in wildlife centers, and possible future reintroduction of wild birds.

Resumo Estudos microbiológicos da sanidade de psitacídeos que serão reintroduzidos são importantes para avaliar se esses animais atuam como portadores de agentes patogênicos para outros animais e humanos. A espectrometria de massa por ionização/dessorção de matriz assistida por laser/tempo de vôo (MALDI-TOF MS) é um método mais rápido e preciso para identificar bactérias na comparação com métodos convencionais de microbiologia. O objetivo deste estudo foi avaliar o estado de saúde de psitacídeos cativos, identificando bactérias Gram-negativas da microbiota fecal por MALDI -TOF MS. Os resultados indicaram alta frequência de bactérias Gram-negativas nas fezes (96,5%), principalmente da família Enterobacteriaceae (88,7%). As mais prevalentes foram Escherichia coli (39,0%), Proteus vulgaris (12,2%), Klebsiella spp. (12,1%) e Raoultella ornithinolytica (8,7%). Proteus hauseri, Citrobacter spp., Morganella morgannii, Providencia rettgeri, Enterobacter spp. e Escherichia hermannii foram isolados com menor frequência. Todos esses agentes são potencialmente patogênicos para os papagaios e podem causar infecções sistêmicas em outros animais e seres humanos. Esses achados reforçam que o MALDI- TOF MS é um método rápido e preciso de identificação do microrganismo e avaliação do estado de saúde dos psitacídeos, fornecendo dados relevantes para auxiliar na tomada de decisões sobre os protocolos sanitários em centros de triagem de animais selvagens e sobre a possibilidade de reintrodução futura.

Pathological and mycological characterization of pulmonary Aspergillus fumigatus infection producing gliotoxin in a captive African grey parrot (Psittacus erithacus)

Aspergillosis, the main causative agent of which is Aspergillus fumigatus, causes mortality in all types of birds. Gliotoxin (GT), one of the multiple virulence factors of A. fumigatus, has a variety of immunosuppressive effects. The corpse of an African grey parrot (Psittacus erithacus) was sent for necropsy and diagnostic rule-out. The lungs were enlarged, firm, and had dark-red coloration, on the parietal faces of both lungs, some semi-circular caseous necrosis areas were observed. The caudal thoracic and abdominal air sacs were thickened and contained a fibrin-heterophilic exudate. Histopathologically, a necrotic and granulomatous bronchopneumonia was observed with intralesional hyphae with characteristics compatible with Aspergillus sp. that were positive with Grocott´s staining. Fibrinous and heterophilic airsacculitis was found in the air sacs. A. fumigatus was isolated from lungs, characterized using serial microcultures, and confirmed using polymerase chain reaction. In addition, GT production was detected in vitro from the culture filtrate in which the isolate was grown; the organic extract was analysed via thin-layer chromatography. This is the first detection of GT in a case of pulmonary aspergillosis in a parrot, which could help to understand the pathogenesis of the disease in psittacines.(AU)

Peritonitis and necrotizing hepatitis in Ara ararauna caused by a foreign body

Background: The ingestion of foreign bodies in parrots has already been described and associated with the curious behaviorof the birds or with stressful conditions. Foreign bodies in the gastrointestinal tract are usually diagnosed through clinicalsigns, laboratory tests, and radiographic findings in the historical data. Foreign bodies are usually metallic and can lodgein any segment of the gastrointestinal tract, commonly found in the proventricle and gizzard. This study investigated acase of necrotizing hepatitis due to a foreign body in Ara ararauna (Linnaeus, 1758).Case: An approximately 9-month-old specimen of caninde macaw, had sudden death and was referred for autopsy. Themacroscopic examination revealed a fibrous, thick, reddish membrane involving the left hepatic lobe and partially the gizzard in continuity with the peritoneum. Inside the capsule, the liver had a friable and necrotic appearance and the gizzardhad a focal perforation area containing a foreign body (gavage tube feeding). We performed the histopathological examination of the liver and gizzard and observed that the membrane surrounding the liver and partially the gizzard had a chronicinflammatory process with a marked proliferation of fibrous tissue and fibrin deposition. The hepatic parenchyma of theleft lobe showed diffuse and marked necrosis, with signs of ischemic necrosis. In the region of transmural perforation ofthe gizzard, the mucosa showed a focal area of extensive necrosis accompanied by the presence of intralesional bacteria.The lesions observed are attributed to the perforation of the organs by the foreign body. It is not known whether the birdingested the object accidently during food handling as a young or due to the curious behavior of the bird or even the stressit may have been exposed to. The post mortem examination revealed localized peritonitis...

Prevalence of endo and enctoparasites in psittaciformes raised in the state of Espirito Santo / Prevalência de endo e ectoparasitos em psittaciformes criados no estado do Espírito Santo

Birds are affected by many parasites, and at wildlife animals are less vulnerable to the changes caused by parasitism, nevertheless in captivity their vulnerability may increase by different factors, including precarious hygiene and management. Birds of the order Psittaciformes frequently live together with people, and it may causes health and environment threats. Then, the objective of the current study was to accomplish parasitological exams in captive Psittaciformes birds aiming to know their parasitological fauna, and evaluate the results with the type of management and the environment where they are, to adopt appropriate prophylaxis measures. This work was authorized by the Ethics Commission in the Use of Animals at UFES from Alegre, and by the Biodiversity Information and Authorization System (SISBIO) of ICMBio. There were analyzed 200 birds of four breedings in Espírito Santo state, being that 63 couple of cockatiels are from domestic breedings in the county of Alegre and 74 individuals of parrots from the Zoo Park da Montanha Zoo, in Marechal Floriano. The fecal samples were collected and processed by the Simple Fluctuation Centrifugal technique in parasitology lab of HOVET-UFES, and the parrots and cockatiels’ feathers were analyzed in the stereomicroscope. The environment and heath aspects where the birds were living were analyzed. The obtained data were summarized by descriptive statistics. The parasites found were Eimeria sp., with a frequency of 9,52% and the lice Neopsittaconirmus sp., with frequency of 4,76% in cockatiels; Capillaria sp. and Ascaridia sp. with a frequency of 75,6 % and 39%, respectively, in parrots, which 36,5% are mixed infection (Capillaria sp. e Ascaridia sp.). It was also found the mite Neorthydelasma sp. with a frequency of 73,3% in mutualism with parrots.
