South America presents the greatest Psittacidae diversity in the world, but also has the highest numbers of threatened parrot species. Recently, exotic viruses have been detected in captive native psittacine birds in Brazil, however, their impacts on the health of wild parrots are still unknown. We evaluated the presence of Chlamydia psittaci, Psittacid alphaherpesvirus 1 (PsHV-1), avipoxvirus and beak and feather disease virus (BFDV) in wild Amazona aestiva, A. brasiliensis and A. pretrei nestlings and in wild caught A. aestiva nestlings seized from illegal trade. Samples were collected from 205 wild nestlings and 90 nestlings from illegal trade and pathogen-specific PCR was performed for each sample. Chlamydia DNA prevalence was 4.7% in A. aestiva and 2.5% in A. brasiliensis sampled from the wild. Sequencing revealed that the C. psittaci sample belonged to the genotype A. PsHV-1, avipoxvirus and BFDV DNA was not detected. These results have conservation implications since they suggest that wild parrot populations have a low prevalence of the selected pathogens and, apparently, they were not reached by the exotic BFDV. Stricter health protocols should be established as condition to reintroduction of birds to the wild to guarantee the protection of Neotropical parrots.

Psittaciform orthobornaviruses are currently considered to be a major threat to the psittacine bird population worldwide. Parrot bornavirus (PaBV) was identified recently in Brazil and, since then, few studies have been conducted to understand the epidemiology of PaBV in captive psittacine birds. In the present study, natural infections by PaBV in South American parrots were investigated in two breeding facilities: commercial (A) and conservationist (B). Thirty-eight psittacine of 21 different species were presented for postmortem examination. Tissue samples were collected and investigated for the presence of PaBV-RNA using RT-PCR. In addition, clinical information about these birds was used when available. PaBV infection was detected in 73.7% of all birds investigated, indicating a wide dissemination of this virus in both facilities. From birds investigated in aviary A, 66.7% showed clinical signs, 100% had typical lesions of proventricular dilatation disease (PDD), 100% had mild to severe proventricular dilatation and 88.9% were PaBV-positive. In birds from aviary B, 27.6% showed clinical signs, 65.5% had typical lesions of PDD, 62% had mild to severe proventricular dilatation and 69% were PaBV-positive. Neurological disease was observed more frequently than gastrointestinal disease. Sequencing analysis of the matrix gene fragment revealed the occurrence of genotype 4 (PaBV-4) in both places. About 15.8% of birds in this study are threatened species. We discussed the difficulties and challenges for controlling viral spread in these aviaries and implications for South American psittacine conservation. These results emphasize the urgent need to develop a national regulatory and health standard for breeding psittacine birds in the country.

CTX‐M‐type extended‐spectrum β‐lactamase (ESBL)‐producing Escherichia coli clones have been increasingly reported worldwide. In this regard, although discussions of transmission routes of these bacteria are in evidence, molecular data are lacking to elucidate the epidemiological impacts of ESBL producers in wild animals. In this study, we have screened 90 wild animals living in a surrounding area of São Paulo, the largest metropolitan city in South America, to monitor the presence of multidrug‐resistant (MDR) Gram‐negative bacteria. Using a genomic approach, we have analyzed eight ceftriaxone‐resistant E. coli. Resistome analyses revealed that all E. coli strains carried blaCTX‐M‐type genes, prevalent in human infections, besides other clinically relevant resistance genes to aminoglycosides, β‐lactams, phenicols, tetracyclines, sulfonamides, trimethoprim, fosfomycin, and quinolones. Additionally, E. coli strains belonged to international sequence types (STs) ST38, ST58, ST212, ST744, ST1158 and ST1251, and carried several virulence‐associated genes. Our findings suggest spread and adaptation of international clones of CTX‐M‐producing E. coli beyond urban settings, including wildlife from shared environments.

Little is known about the diversity of adenoviruses in wild birds and how they have evolved and are maintained in complex ecosystems. In this study, 409 samples were collected from woodland birds caught for banding (droppings), birds submitted to a wildlife hospital (droppings and tissues), silver gulls (droppings or tissues), and feral pigeons (Columbia livia; oral, cloacal swabs, or tissues) from the Greater Sydney area in NSW, Australia. Additional samples were from native pigeons and doves (swabs) presented to the Healesville Sanctuary, VIC, Australia. Samples were screened for adenovirus DNA using degenerate primers and polymerase chain reaction. Adenovirus sequences were detected in eighty-three samples representing thirty-five novel amino acid sequences. Fourteen novel sequences were atadenoviruses, seven were aviadenoviruses, twelve were siadenoviruses, and one was a mastadenovirus. Sequences from passerine birds were predominately found to form a single lineage within the atadenoviruses, a second lineage in the siadenoviruses, and a third smaller aviadenovirus lineage. These viruses appeared to have co-evolved with a diverse group of woodland birds that share similar habitat. Evidence for host/virus co-evolution in some viruses and a wide host range in others was observed. A high prevalence of adenovirus infection was found in rainbow lorikeets (Trichoglossus haematodus), galahs (Eolophus roseicapilla), and sulphur-crested cockatoos (Cacatua galerita). Sequences were either identical to or mapped to already established lineages in the Aviadenovirus, Siadenovirus, and Atadenovirus genera, suggesting a possible origin of the psittacine adenoviruses in ancestral Australian psittacine birds. The sequences of passerine and psittacine origin provided insight into diversity and structure of the Atadenovirus genus and demonstrated for the first-time viruses of passerine origin in the Aviadenovirus genus. Four unrelated adenovirus sequences were found in silver gull samples (Chroicocephalus novaehollandiae), including one of pigeon origin, suggesting environmental virus exposure. Three pigeon adenovirus types were detected in feral pigeons and infection prevalence was high. Evidence for host switching between invasive species and native species and native species and invasive species was documented. A variant of a murine adenovirus was detected in kidney tissue from two bird species suggesting mouse to bird transmission.

The present study analyzed gastrointestinal helminth communities in 265 wild pigeons (Columba livia) living in the municipalities of São Paulo and Tatuí, state of São Paulo, Brazil, over a one-year period. The birds were caught next to grain storage warehouses and were necropsied. A total of 790 parasites comprising one nematode species and one cestode genus were recovered from 110 pigeons, thus yielding an overall prevalence of 41.5%, mean intensity of infection of 7.2 ± 1.6 (range 1-144) and discrepancy index of 0.855. Only 15 pigeons (5.7%) presented mixed infection. The helminths isolated from the birds were Ascaridia columbae (Ascaridiidae) and Raillietina sp. (Davaineidae). The birds’ weights differed according to sex but this did not influence the intensity of infection. The overall prevalence and intensity of infection did not differ between the sexes, but the prevalence was higher among the birds from Tatuí (47.8%). The gastrointestinal helminth community of C. livia was characterized in the two areas studied and parasite homogeneity was observed over the 12 months analyzed at both locations. These results make contributions to the current literature on health aspects of wild C. livia populations.

The Black vulture (Coragyps atratus) is the most common species of vulture and is widespread in all America. The species feeds on rotting carcasses, and large groups are frequently seen in urban areas, concentrating especially on rubbish dumps. Although C atratus is a very common species in some areas, little is known about its health in the wild. The aim of this study was to determine hematologic RIs of wild adult Black vultures. Blood samples were obtained from 70 wild Black vultures captured in São Paulo, Brazil. Hematologic values were determined using conventional techniques applicable to birds. Reference intervals were determined using an Excel program with Reference Value Adviser (version 2.0). After statistical analysis, the following RIs were determined: HGB 8.5–12.5 g/dL, PCV 42.3–54.5%, MCV 203.2–402.6 fL, MCHC 17.4–26.2 g/dL, total solids 2.4–4.8 g/dL, RBC count 1.16–2.48 × 106/μL, WBC count 5.93–27.14 × 103/μL, heterophils 3.40–21.58 × 103/μL, lymphocytes 0.19–5.16 × 103/μL, eosinophils 0.0–3.07 × 103/μL, monocytes 0.0–1.49 × 103/μL, basophils 0.0–0.25 × 103/μL, and heterophil:lymphocyte ratio 1.3–36.9. Thrombocyte mean was 14.14 × 103/μL. Baseline hematologic data obtained in this study provide RIs that will be useful given that few studies have been carried out on the health of New World vultures.

The red-tailed Amazon parrot (Amazona brasiliensis) is a threatened species of psittacine bird that inhabit coastal regions of Brazil. In view of the threat of this species, the aim of this study was to perform a health evaluation in wild nestlings in Rasa Island, determining the prevalence of enterobacteria and infectious agents according to type of nest. Blood samples were collected from 64 birds and evaluated for antibodies of Chlamydia psittaci by commercial dot-blot ELISA. Cloacal and oropharyngeal swabs samples were collected from 23 birds from artificial wooden nests, 15 birds from PVC nests and 2 birds from natural nests for microbiological analysis. Swab samples were collected from 58 parrots for C. psittaci detection by PCR and from 50 nestlings for Avian Influenza, Newcastle Disease and West Nile viruses’ detection analysis by real-time RT-PCR. Ten bacterial genera and 17 species were identified, and the most prevalent were Escherichia coli and Klebsiella oxytoca. There was no influence of the type of nest in the nestlings’ microbiota. All samples tested by ELISA and PCR were negative. There is currently insufficient information available about the health of A. brasiliensis and data of this study provide a reference point for future evaluations and aid in conservation plans.

SUMMARYZoonotic diseases are a significant health threat for humans and animals. To better understand the epidemiology, etiology, and pathology of infectious agents affecting humans and animals combined approaches are needed. Here we describe an epidemiological investigation conducted by physicians and veterinarians after a reported case of psittacosis. Upon admission suffering from respiratory distress syndrome in a hospital and with a history of bird contact, a female patient was serologically diagnosed with psittacosis. After the case notification, veterinarians were able to investigate the source of infection by detecting Chlamydia psittaci in her pet cockatiel. The bird was hospitalized and successfully treated. In addition, the establishment where the pet bird was purchased was traced and through molecular techniques other birds intended to be sold as pets tested positive for C. psittaci. As a result, sanitary measures were applied and the establishment then was closed down. The birds intended for the pet commerce were treated and retested with negative molecular results for C. psittaci, thus avoiding disease propagation. Reliable data about zoonotic diseases can only be generated through the application of multidisciplinary approaches which take into account the epidemiological factors and interactions of humans, animals and their environments as an integrated system.

Pathogens of veterinary and medical importance were investigated in 240 feral pigeons (Columba livia) captured in warehouses in São Paulo State, Brazil for one year. Rapid serum agglutination test (RST) was performed for the detection of antibodies against Mycoplasma synoviae, Mycoplasma gallisepticum and Salmonella Pullorum/Gallinarum. Positive samples were submitted to hemagglutination inhibition (HI) and tube seroagglutination tests, respectively. Molecular techniques (RT-PCR and PCR) were performed for Newcastle Diseases Virus (NDV) and Chlamydia psittaci diagnosis. Additionally, HI test was applied to detect antibodies against NDV. Serological results by RST were 3.3% positive for M. synoviae, 2.5% for M. gallisepticum, and 0.4% for S. Pullorum/Gallinarum, all negative on the confirmatory tests performed. NDV RNA or antibodies were not detected. C. psittaci DNA was detected in 13% of the samples. Further research on pigeon health status should be conducted because this species is highly adaptable and their numbers are rapidly rising around the world, posing risks for animals and human beings.

Cryptococcus spp. are responsible for around one million cases of meningitis every year. Fluconazole (FLU) is commonly used in the treatment of cryptococcosis, mainly in immunocompromised patients and the resistance is usually reported after long periods of treatment. In this study, the morphological characterization and virulence profile of FLU-susceptible and FLU-resistant clinical and environmental isolates of C. neoformans and C. gattii were performed both in vitro and in vivo using the Galleria mellonella model. FLU-susceptible isolates from C. neoformans were significantly more virulent than the FLU-resistant isolates. FLU-susceptible C. gattii isolates showed a different virulence profile from C. neoformans isolates where only the environmental isolate, CL, was more virulent compared with the resistant isolates. Cell morphology and capsule size were analyzed and the FLU-resistant isolates did not change significantly compared with the most sensitive isolates. Growth at 37°C was also evaluated and in both species, the resistant isolates showed a reduced growth at this temperature, indicating that FLU resistance can affect their growth. Based on the results obtained is possible suggest that FLU resistance can influence the morphology of the isolates and consequently changed the virulence profiles. The most evident results were observed for C. neoformans showing that the adaptation of isolates to antifungal selective pressure influenced the loss of virulence.

A existência de populações numerosas de pombos (Columba livia) em centros urbanos, em quase todo o mundo, tem se tornado um risco à saúde pública em vista das zoonoses que podem transmitir. A infecção por Chlamydophila psittaci foi avaliada em pombos que frequentam áreas públicas, como praças, ruas e pontos turísticos na cidade de Salvador, Bahia, por meio da PCR em amostras de fezes frescas, suabes cloacais e orofaríngeos. O estudo revelou uma frequência de infecção por C. psittaci de 11,7% (16/137) dos pombos, e oito dos 10 locais pesquisados apresentavam aves infectadas. A detecção de C. psittaci em amostras de cloaca e orofaringe foi maior (15,8% - 3/19) que em amostras de fezes frescas (11% - 13/118). Os resultados demonstram a ocorrência de infecção por C. psittaci em pombos que habitam as áreas públicas da cidade de Salvador e apontam para a necessária elaboração de medidas de controle e monitoramento das populações de pombos urbanos, bem como de ações voltadas à conscientização da sociedade sobre os riscos à saúde pública.

Chlamydia psittaci is the causative agent of psittacosis. The illness varies from a mild disease to a fatal systemic illness. In recent years the role of C. psittaci causing atypical pneumonia has become more appreciated. Here we present a severe psittacosis case resulting in acute respiratory distress syndrome (ARDS) in a woman which had contact with a pet cockatiel. Chest computed tomography scan demonstrated extensive air-space disease interspersed by airbronchograms in the dependend portions of both lower lobes. Focal areas of consolidation were also observed in the middle and superior lobes. The diagnosis was suggested on the basis of epidemiologic criteria of exposure to birds and confirmed by a serological test revealing high titers of IgG by MIF assay. In these cases psittacosis should be considered in the differential diagnosis.

Chlamydia psittaci is the aetiological agent of chlamydiosis in birds, especially Psittaciformes. The objective of the present study was to detect C. psittaci by means of semi-nested PCR among psittacine birds sold at pet markets and kept as pet birds in Salvador, Bahia, Brazil. Questionnaires were used to identify risk factors involved in the epidemiology of the disease. In addition, the management of birds and cages was observed at each location studied. The frequency of C. psittaci infection was 10.6 % (33/311) in the psittacine birds studied. Birds kept in households were less frequently positive (3.4 %; 5/148) than those at pet markets (17.2 %; 28/163). Among the several factors analysed in the epidemiology of the disease, only population density (P = 0.001) and cage hygiene (P = 0.041) in birds at pet markets were significantly associated with C. psittaci infection. These results demonstrate the presence of C. psittaci infection in Psittaciformes kept as pets and held at pet markets in Salvador, Bahia, showing that this micro-organism is a public health concern. Control measures should be encouraged to prevent the spread of the agent among birds, as well as among employees and customers.

Birds of the Cracidae family (curassows, guans, and chachalacas) are endemic of the Neotropics and 50 species are currently classified. Brazil has 22 species, seven of which are considered threatened. The Alagoas Curassow (Pauxi mitu) species is considered extinct in the wild; but about 120 birds are alive in captivity. Conservation of this species depends entirely on correct management. Health reports of both wildlife and captive curassows are rare. In this study the presence of Escherichia coli was evaluated in 23 healthy Alagoas Curassows from two private breeding centres. E. coli was isolated from cloacal swabs, and the presence of genes encoding cytotoxic necrotising factor 1 (cnf1), alpha-haemolysin (hly), aerobactin (iuc), serum resistance (iss) and the following adhesions: S fimbriae (sfa), pili associated with pyelonephritis (pap) and temperature-sensitive haemagglutinin (tsh) were investigated. E. coli was isolated from 78.3% (18/23) of the birds, and the percentage of curassows colonized by E. coli was similar between the two facilities. From the 22 E. coli isolates, 15 (68.2%) were positive for at least one virulence factor by PCR, and the most frequently found gene was iss (50%). No curassows had clinical signs of disease. Nevertheless, the presence of some E. coli strains may be a concern to the wildlife in captivity. Additional health surveillance studies are essential to guarantee successful conservation programmes for threatened cracids in Brazil.

The hyacinth macaw (Anodorhynchus hyacinthinus) is the largest species of psittacine birds. It is considered endangered and illegal trade is one of the main factors involved in its decline. In this study, 26 hyacinth macaws maintained under poor husbandry conditions and destined for the illegal trade were confiscated in São Paulo State, Brazil. These birds were evaluated for the presence of antibodies against Chlamydophila psittaci by complement fixation test and C. psittaci DNA by seminested polymerase chain reaction. Results showed that 65.4% of the macaws were positive for at least one test. Birds with subclinical infections can shed chlamydiae intermittently over long periods, contributing to the dissemination of the agent. Global trade is one of the most important drivers of disease emergence. The high percentage of positive samples in this study emphasizes the potential risk that the illegal trade of wild birds represents for both human and animal health.
