RESUMEN

A 40-year old female chimpanzee (Pan troglodytes) developed hyporexia, weight loss, followed by progressive and complete blindness. Tomography demonstrated an intracranial mass in the rostroventral brain involving the optic chiasm, with a presumptive diagnosis of neoplasm. However, histopathology revealed a granulomatous meningoencephalitis, and tissue samples tested positive for Mycobacterium tuberculosis.

RESUMEN

BACKGROUND: Marmosets (Callithrix sp.), including black-tuffed marmosets (C. penicillata), are neotropical primates that can be highly adapted to urban environments, especially parks and forested areas near cities. Staphylococcus spp. are part of the microbiota of many different hosts and lead to opportunistic severe infection. Isolates from wild animals can be resistant to antimicrobial drugs. However, there are a few studies that evaluated Staphylococcus spp. in neotropical primates. The goal of this study was to evaluate Staphylococcus spp. isolated from free-ranging black-tuffed marmosets. METHODS: Marmosets were captured in six urban parks. After sedation, skin and rectal swabs and feces were sampled. Staphylococcus spp. isolates were identified by MALDI-ToF and their antimicrobial susceptibility was determined. RESULTS: Over 30% of captured individuals were positive for Staphylococcus spp., and S. aureus was the most isolated species followed by Mammaliicoccus (Staphylococcus) sciuri. With the exception of the marmoset subjected to necropsy, none of the other had lesions, which supports that notion that Staphylococcus spp. are members of the microbiota, but also opportunistic pathogens. Most isolates were susceptible to all antimicrobials tested; however, one isolate of S. epidermidis was resistant to multiple antimicrobials (penicillin, cefoxitin, ciprofloxacin, clindamycin, and erythromycin). We considered S. aureus as the main staphylococci to colonize black-tuffed marmosets. CONCLUSIONS: Black-tuffed marmosets can be colonized by several Staphylococcus species, most frequently by S. aureus, and the majority of isolates were sensible to the antimicrobials tested. One S. epidermidis isolate was considered multidrug resistant.

RESUMEN

Chylothorax is the accumulation of lymph in the thoracic cavity, and it has never been reported in neotropical primates. An emperor tamarin died and at necropsy chylothorax associated with pulmonary compressive atelectasis was diagnosed. Idiopathic chylothorax can be a cause of respiratory insufficiency and death in tamarins.

RESUMEN

The epidemiology of Staphylococcus spp. has become a major concern among humans and animals due to increasing antimicrobial resistance and frequent reports of infection. Despite the importance of animals as reservoirs for staphylococci, little is known about the epidemiology of Staphylococcus spp. in most nondomestic species, including canids and felids. This study evaluated the frequency, distribution, and patterns of antimicrobial resistance of staphylococcal species isolated from captive felids and canids from Belo Horizonte Zoo, Brazil. Rectal, oral, and nasal swabs from apparently healthy maned wolves (Chrysocyon brachyurus, n= 7), a lion (Panthera leo, n = 1), jaguars (Panthera onca, n = 3), and one swab of a cougar (Puma concolor) with an ear infection were streaked onto mannitol salt agar. Colonies identified by matrix-assisted laser desorption/ionization-time of flight mass spectrometry, polymerase chain reaction for the Staphylococcus intermedius group (SIG), and 16S rRNA gene sequencing. Isolates were subjected to antimicrobial susceptibility tests and Staphylococcus pseudintermedius strains were subjected to multilocus sequence typing. Staphylococcus species were isolated from 24 of the 34 samples (70.6%). Among the isolated strains, S. pseudintermedius and Staphylococcus felis were the most frequent species (41.7 and 25%, respectively). Five novel sequence types were identified among the S. pseudintermedius isolates. Resistance to tetracycline (7/24, 29.2%) or penicillin (6/23, 26.1%) was significantly higher than the other antimicrobial agents tested (P < 0.05). One isolate, Staphylococcus nepalensis, was positive for mecA and resistant to five antimicrobials, and was thus classified as multidrug-resistant. The present work suggests that maned wolves are natural hosts of SIG and also reports the isolation of S. felis in sick and healthy, captive, nondomestic carnivores. The isolated staphylococci were susceptible to most classes of antimicrobials tested. However, the multidrug-resistance capability of an S. nepalensis strain reinforces the hypothesis that felids and canids act as reservoirs of pathogens with antimicrobial resistance.

RESUMEN

Streptococcus pasteurianus is associated with endocarditis and sepsis in humans. A puerperal emperor tamarin died, and necropsy showed a bacterial endocarditis with sepsis. DNA sequencing from the paraffinized heart tissue was compatible with S. pasteurianus. S. pasteurianus could be an important agent associated with sepsis in tamarins.

RESUMEN

Mammaliicoccus (Staphylococcus) sciuri has been rarely associated with infections and sepsis in humans. A 3-month-old male western lowland gorilla (Gorilla gorilla gorilla), born under human care, died after a traumatic event. Histologic, microbiologic, and molecular findings in postmortem demonstrated a suppurative meningoencephalitis and bacteremia associated with M. sciuri infection.

RESUMEN

Some wild species of mammals and birds are prone to excessive iron accumulation, especially when maintained in human care. Hemosiderosis is the process of intracellular accumulation of iron without evidence of toxicity, whereas hemochromatosis is characterized by severe iron accumulation with accompanying organ damage. Iron storage disease (ISD) occurs when organ damage is severe and causing clinical signs. This retrospective study investigated the occurrence of hemosiderosis and ISD across a variety of avian taxa, including captive and free-ranging birds. Archived paraffin-embedded hepatic samples from 103 birds from Belo Horizonte Zoo that died naturally in the period of 2008 to 2018 were re-evaluated with histologic and morphometric techniques, focusing on the identification and scoring of iron deposits in hepatocytes and the quantification of total affected hepatic area. The birds represented 13 orders, 22 families, and 52 genera, and 66 (64.0%) had some degree of iron accumulation in their liver. Importantly, no statistical difference was observed in the occurrence of iron accumulation between families, orders, or origin (free-ranging or captive). Direct and positive correlation was observed between the total area affected by the iron deposits and the histologic score. In this study, there were two cases with severe iron accumulation and clinical signs compatible with ISD: a barefaced curassow (Crax fasciolata) and a channel-billed toucan (Ramphastos vitellinus). This study indicates that iron accumulation may occur in a wide range of avian species, with frequencies and intensities that are similar between free-ranging birds and those in human care. It describes for the first time the occurrence of ISD in a Galliform species.

RESUMEN

BACKGROUND: Osteosarcoma is a malignant mesenchymal bone tumor. Although it is a common tumor in the appendicular skeleton of dogs and cats, it is rarely reported in birds. Retroviruses are usually associated with solid tumor development in different avian species. CASE PRESENTATION: This report aims to describe a case of osteosarcoma associated with the avian leukosis virus in a captive bare-faced curassow (Crax fasciolata). A captive adult female bare-faced curassow presented with lameness, hyporexia, and a non-ulcerative and firm tumor in the right femur. The bird was euthanized due to the poor prognosis. Histopathology revealed an infiltrative mesenchymal neoplasm consisting of spindle cells with moderate cell pleomorphism, organized in bundles and interspersed by marked deposition of the osteoid matrix, which was compatible with osteosarcoma affecting both femur and tibiotarsus, with renal metastasis. Immunohistochemistry of the primary and metastatic tumor demonstrated vimentin expression by neoplastic cells. Samples of the neoplasm, bone marrow, and spleen were processed for PCR, which enabled the demonstration of proviral avian leukosis virus (ALV) DNA. CONCLUSIONS: To the best of our knowledge, this is the first report of an osteosarcoma in a bare-faced curassow with an unusual polyostotic manifestation and associated with ALV infection.

RESUMEN

Cardiac disease is of importance in captive chimpanzee (Pan troglodytes) health. Here we report an eosinophilic and necrotizing myocarditis in a 17-y-old chimpanzee with no previous history of cardiac disease that progressed to death within 48 h. Toxic and infectious causes were ruled out. The chimpanzee had eosinophilia at different occasions in previous years. The animal had a severe, diffuse, and acute monophasic necrotizing myocarditis, with a moderate lymphoplasmacytic infiltrate that was rich in eosinophils. Ante- and postmortem investigations are compatible with an unusual eosinophilic myocarditis with clinical evolution and morphology comparable with human eosinophilic myocarditis secondary to hypereosinophilic syndrome.

RESUMEN

BACKGROUND: Toxoplasmosis is an important disease affecting captive non-human primates. The goal of this study was to assess the seroprevalence and pathological findings of toxoplasmosis in different species of captive primates. METHODS: Six captive neotropical primates died naturally due to Toxoplasma gondii infection and were necropsied. Tissue samples were evaluated by histopathology and immunohistochemistry. Serum samples from 57 captive neotropical and Old-world primates housed at the Belo Horizonte zoological garden were analyzed by indirect fluorescent antibody test (IFAT), enzyme-linked immunosorbent assay (ELISA), and indirect hemagglutination assay (IHA). RESULTS: Neotropical primates had lesions compatible with toxoplasmosis with immunolabeled intralesional T gondii. All Old-World primates (10/10), but only three neotropical primates (3/47), all belonging to the Sapajus apella species (3/6), were serologically positive. CONCLUSIONS: Our results suggest a higher susceptibility of neotropical primates to toxoplasmosis. However, this study also supports the hypothesis that Sapajus apella may be naturally resistant.

RESUMEN

Sloths are xenarthrans from Central and South America with a highly adapted morphophysiology. Five of the six known species of sloths are found in Brazil, among which Bradypus torquatus (maned three-toed sloth) is considered a vulnerable species by International Union for Conservation of Nature. Nevertheless, knowledge on health and disease of sloths is very scarce, thus this study aimed to describe macroscopic and microscopic findings in 36 Brazilian sloths. The most common findings included iron storage disorder, probable bacterial pneumonia, gastric and intestinal nematode parasitism, and a presumptive diagnosis of systemic mastocytosis.

RESUMEN

A 37-yr-old captive common hippopotamus (Hippopotamus amphibius) developed lethargy and decline in mobility that progressed to death, despite supportive therapy. Histopathologic examination revealed severe, diffuse, intravascular and interstitial infiltration of neoplastic histiocytes in the spleen, liver, lymph nodes, lungs, large intestine, kidneys, and thyroid gland. Neoplastic cells were pleomorphic with marked anisocytosis and anisokaryosis, scattered multinucleated giant cells, numerous bizarre mitotic figures, and marked erythrophagocytosis. Immunohistochemistry demonstrated that neoplastic cells were positive for ionized calcium-binding adapter molecule 1 (a histiocytic marker) and negative for CD3 (a T-cell marker) and myeloperoxidase, confirming the diagnosis of systemic histiocytic sarcoma.

RESUMEN

Bluetongue Virus (BTV) and Epizootic Hemorrhagic Disease Virus (EHDV) are Orbiviruses primarily transmitted by their biological vector, Culicoides spp. Latreille, 1809 (Diptera: Ceratopogonidae). These viruses can infect a diverse range of vertebrate hosts, leading to disease outbreaks in domestic and wild ruminants worldwide. This study, conducted at the Belo Horizonte Municipal Parks and Zoobotany Foundation (FPMZB-BH), Minas Gerais, Brazil, focused on Orbivirus and its vectors. Collections of Culicoides spp. were carried out at the FPMZB-BH from 9 December 2021 to 18 November 2022. A higher prevalence of these insects was observed during the summer months, especially in February. Factors such as elevated temperatures, high humidity, fecal accumulation, and proximity to large animals, like camels and elephants, were associated with increased Culicoides capture. Among the identified Culicoides spp. species, Culicoides insignis Lutz, 1913, constituted 75%, and Culicoides pusillus Lutz, 1913, 6% of the collected midges, both described as competent vectors for Orbivirus transmission. Additionally, a previously unreported species in Minas Gerais, Culicoides debilipalpis Lutz, 1913, was identified, also suspected of being a transmitter of these Orbiviruses. The feeding preferences of some Culicoides species were analyzed, revealing that C. insignis feeds on deer, Red deer (Cervus elaphus) and European fallow deer (Dama dama). Different Culicoides spp. were also identified feeding on humans, raising concerns about the potential transmission of arboviruses at the site. In parallel, 72 serum samples from 14 susceptible species, including various Cervids, collected between 2012 and 2022 from the FPMZB-BH serum bank, underwent Agar Gel Immunodiffusion (AGID) testing for BTV and EHDV. The results showed 75% seropositivity for BTV and 19% for EHDV. Post-testing analysis revealed variations in antibody presence against BTV in a tapir and a fallow deer and against EHDV in a gemsbok across different years. These studies confirm the presence of BTV and EHDV vectors, along with potential virus circulation in the zoo. Consequently, implementing control measures is essential to prevent susceptible species from becoming infected and developing clinical diseases.

RESUMEN

Cururu toad (Rhinella marina group) is widely distributed in Brazil. Lesser grison (Galitic cuja) is a South American mustelid. This is the first report of natural poisoning in a free-ranging lesser grison by Rhinella toad parotoid gland secretion (PGS). Five minutes after biting a toad, the lesser grison developed convulsion, dying within 1.5 h. Mass spectrometry analysis of a milky-whitish secretion found in the lesser grison oral cavity allowed identification of a bufotoxin and a new bufonid peptide.

RESUMEN

Visceral leishmaniasis (VL) is a zoonosis and the dog is considered the most important urban reservoir. Cases in cats have been reported, but little is known about Leishmania infection and disease in wild felids and canids kept in captivity in endemic areas. Thus, the serological pattern of wild felids and canids kept in captivity at the Belo Horizonte Zoological Garden was investigated using two primary antigens for conventional ELISA: k39 and rKDDR, as well as three serological rapid kits: Dual Path Platform (DPP®) immunochromatographic test, rKDDR Immunochromatographic assay and ELISA SNAP Leishmania IDEXX®. A total of 21 serum samples, 13 of wild felids and 8 wild canids of varying age and sex were evaluated. The results obtained in the tests were analyzed by agreement using Kappa coefficient, and between ELISA antigens all the analysis performed had showed significant agreement among both of them, as well between the three immunochromatographic tests. The results demonstrated that there is serological evidence of wild animals seropositive for Leishmania antibodies at the Belo Horizonte Zoological Garden, and that all the antigens and rapid tests used can be employed in serological screening for VL in wild felids and canids.

RESUMEN

ABSTRACT: Aerococcus viridans is an emerging pathogen for humans and livestock animals, mainly associated with genitourinary infections cases. Its occurrence in wild mammals has never been reported. The aim of this study was to determine the etiological agent associated with clinical a case of a genital infection in a female African elephant (Loxodonta africana). Phylogenetic analysis and antimicrobial susceptibility profile of the isolate were also addressed. The animal presented frequent cases of genital infection with intermittent white secretion. Purulent secretion was sampled and submitted to bacteriological exam. The isolate obtained was thus identified by phenotypic and molecular methods as A. viridans and was found to be similar to human pathogenic isolates in BLASTn and phylogenetic analysis. The isolate was sensitive to almost all antimicrobials evaluated, presenting resistance to ciprofloxacin and norfloxacin. This is the first report of occurrence of A. viridans infection in the genital tract of an African elephant.


RESUMO: Aerococcus viridans é um patógeno emergente para seres humanos e animais de produção, principalmente associado a casos de infecções geniturinárias. Sua ocorrência em mamíferos selvagens nunca foi relatada. O objetivo deste estudo foi determinar o agente etiológico associado a um caso clínico de infecção genital em uma fêmea de elefante africano (Loxodonta africana). Análises filogenéticas e perfil de susceptibilidade antimicrobiana do isolado também foram avaliados. O animal apresentou casos frequentes de infecção genital com eliminação de secreção branca intermitente. A secreção purulenta foi coletada e submetida a exame bacteriológico. O isolado obtido foi identificado por métodos fenotípicos e moleculares como A. viridans e apresentou alta similaridade a isolados humanos patogênicos nas análises de BLASTn e filogenética. O isolado foi sensível a quase todos os antimicrobianos avaliados, apresentando resistência à ciprofloxacina e norfloxacina. Este é o primeiro relato de ocorrência de infecção por A. viridans no trato genital de elefante africano.
