Ex situ population of the Harpy Eagle and its potential for integrated conservation.

A main priority in conservation is the protection of species in their natural habitat. However, ex situ management of threatened species is a recognised strategy of conservation. Harpy Eagles () are removed from the wild due to illegal capture, nest tree destruction, or other conflict sources.

Canine distemper virus and canine adenovirus type-2 infections in neotropical otters (Lontra longicaudis) from Southern Brazil.

All descriptions of infectious diseases affecting otters were published in the Northern Hemisphere, with no occurrence identified in neotropical otters (Lontra longicaudis). Consequently, a retrospective histopathological study using archival tissue samples from six free-living neotropical otters was done to investigate the possible occurrence of disease patterns associated with common viral infectious disease agents of the domestic dogs. Immunohistochemical (IHC) assays were designed to identify intralesional tissue antigens of canine distemper virus (CDV), and canine adenovirus-1 (CAdV-1) and canine adenovirus-2 (CAdV-2).

Immunohistochemical evidence of canine morbillivirus (canine distemper) infection in coatis (Nasua nasua) from Southern Brazil.

The pathological and immunohistochemical (IHC) findings associated with infection due to canine morbilivírus (canine distemper virus, CDV) are described in coatis (Nasua nasua). Tissue fragments of coatis (n = 13) that died at the Bela Vista Sanctuary, Paraná, Southern Brazil, were routinely processed for histopathology to identify the main histopathologic patterns as compared to that of the domestic dog. Selected formalin-fixed paraffin-embedded (FFPE) tissue fragments of the lungs, liver, urinary bladder and small intestine were used in IHC assays designed to identify the antigens of CDV, canine adenovirus (CAdV-1 and CAdV-2) and canine parvovirus type 2 (CPV-2).

Immunohistochemical identification of antigens of canine distemper virus in neotropical felids from Southern Brazil.

The pathologic and immunohistochemical findings associated with infections due to canine distemper virus (CDV) are described in the cougar (Puma concolor), margay (Leopardus wiedii) and jaguarundi (Herpailurus yagouaroundi) from Southern Brazil. Tissue sections of the neotropical felids (n = 3) that died at the Bela Vista Sanctuary, Paraná, Southern Brazil were routinely processed for histopathology to identify possible histopathologic patterns associated with infections due to CDV. Selected formalin-fixed paraffin embedded tissue sections of the lungs and urinary bladder were used in immunohistochemical assays designed to identify the antigens of CDV.

Multiple bluetongue virus serotypes causing death in Brazilian dwarf brocket deer (Mazama nana) in Brazil, 2015-2016.

Bela Vista Biological Sanctuary (RBV) is a protected area of Itaipu Binacional, a hydroelectric power company located on the border of Brazil and Paraguay. A captive population of Brazilian dwarf brocket deer (Mazama nana, Cervidae, Artiodactyla) is maintained for conservation purposes. Despite the reproductive success of the animals, outbreaks of a fatal hemorrhagic disease have been registered over the years, compromising conservation efforts.

IMMUNOHISTOCHEMICAL AND MOLECULAR EVIDENCE OF PUTATIVE NEORICKETTSIA INFECTION IN COATIS ( NASUA NASUA) FROM SOUTHERN BRAZIL.

The pathologic, molecular, and immunohistochemical findings associated with Neorickettsia helminthoeca are described in coatis ( Nasua nasua). Tissue sections (small intestine, lungs, kidney, liver, and spleen) of coatis ( n = 3) that died at the Bela Vista Biological Refuge, Foz do Iguaçu, Paraná, southern Brazil were routinely processed from histopathology. Selected formalin-fixed paraffin-embedded (FFPE) tissue sections of the small intestine, lungs, and spleen were used in an immunohistochemical (IHC) assay designed to identify the antigens of N.

Microscopic and molecular identification of hemotropic mycoplasmas in South American coatis (Nasua nasua).

Hemoplasmas were detected in two apparently healthy captive South American coatis (Nasua nasua) from southern Brazil during an investigation for vector-borne pathogens. Blood was subjected to packed cell volume (PCV) determination, a commercial real-time PCR panel for the detection of Anaplasma spp., Babesia spp.

Occurrence of hemotropic mycoplasmas in non-human primates (Alouatta caraya, Sapajus nigritus and Callithrix jacchus) of southern Brazil.

Hemoplasmas, the erythrocyte-associated mycoplasmas, have been detected in several primates, causing mostly subclinical infection. This study aimed to determine the prevalence of hemoplasma infection in captive and free-ranging monkeys from southern Brazil, as well as factors and hematological abnormalities associated with infection. Blood samples from 40 non-human primates (NHP) were tested for hemoplasmas and coinfections.

Doppler ultrasonography of the artery in harpy eagles ().

Twenty harpy eagles () without systemic or ocular diseases were examined to measure blood velocity parameters of the artery using Doppler ultrasonography. Pectinate artery resistive index (RI) and pulsatility index (PI) were investigated using ocular Doppler ultrasonography. The mean RI and PI values across all eyes were 0.

Chemical Restraint of Free-ranging South American Coatis ( Nasua nasua ) with a Combination of Tiletamine and Zolazepam.

Occurrence of antibodies anti -Toxoplasma gondii, Neospora caninum and Leptospira interrogans in a captive deer herd in Southern Brazil.

A large number of Brazilian zoos keep many endangered species of deer, however, very few disease surveillance studies have been conducted among captive cervids. Blood samples from 32 Brazilian deer (Blastocerus dichotomus, Mazama nana and Mazama americana) kept in captivity at Bela Vista Biological Sanctuary (Foz do Iguaçu, Brazil) were investigated for 10 ruminant pathogens, with the aims of monitoring deer health status and evaluating any potential zoonotic risk. Deer serum samples were tested for Brucella abortus, Leptospira (23 serovars), Toxoplasma gondii, Neospora caninum, bovine viral diarrhea virus, infectious bovine rhinotracheitis virus, foot-and-mouth disease virus, western equine encephalitis virus, eastern equine encephalitis virus and Venezuelan equine encephalitis virus.

The use of altrenogest to avoid hyperestrogenism after eCG-hCG ovulation induction in southern tigrina (Leopardus guttulus).

The goal of this study was to optimize an ovulation induction protocol for use with artificial insemination in the southern tigrina (Leopardus guttulus). The specific aims were to report the efficacy of using altrenogest, an oral progestin (Regumate, MSD Animal Health, Merck Animal Health), to suppress ovarian activity and prevent follicular hyperstimulation and hyperestrogenism after the administration of exogenous eCG and hCG. To monitor ovarian responses, fecal estrogen and progestogen metabolites were quantified by enzyme immunoassay in females before and after intramuscular administration of 200-IU eCG and 150-IU hCG in two trials, 4 months apart.

Hemotropic mycoplasma in a free-ranging black howler monkey (Alouatta caraya) in Brazil.

Hemotropic mycoplasmas are bacteria that infect erythrocytes and cause subclinical infections to life-threatening disease. We describe hemotropic mycoplasma infection in a free-ranging black howler monkey (Alouatta caraya). This is the first molecular detection of a hemotropic mycoplasma in a nonhuman primate from Brazil.

Serologic survey for Leptospira spp. in captive neotropical felids in Foz do Iguaçu, Paraná, Brazil.

Leptospirosis is a bacterial zoonosis of worldwide distribution and is endemic in tropical countries, where rodents and other wild mammals are abundant and may act as reservoirs. Leptospirosis has become a concern in captive wild animals, due mostly to their exposure to contaminated urine or environment. Although domestic cats (Felis catus) have been reported refractory to leptospirosis, serology and disease in captive wild felids is still unclear.

Mycoplasma ovis in captive cervids: prevalence, molecular characterization and phylogeny.

Hemotrophic mycoplasmas (hemoplasmas) are bacteria that attach to red blood cells of mammals, leading to acute and/or subclinical disease in infected animals. It has been suggested that Mycoplasma ovis, a hemoplasma that infects sheep and goats worldwide, may also infect deer. The aim of this study was to evaluate whether South American deer are infected with M.

Serological survey of Toxoplasma gondii in captive Neotropical felids from Southern Brazil.

Toxoplasma gondii is the causative intracellular protozoan of toxoplasmosis in human being and animals. Members of the Felidae family are considered the single definitive host for the infection; both wild and domestic cats are able to excrete oocysts in the environment. Wild cats maintained in captivity may serve as source of infection for other clinically susceptible animals in the same environment.
