Howler monkey capture is an arduous and expensive task requiring trained specialized professionals. We compared strategies methods to most efficiently Alouatta guariba clamitans in remnants of the Atlantic Forest Rio de Janeiro its bordering states Minas Gerais São Paulo. tested whether or not success expeditions forest with anesthetic darts, nets, baited traps differed without support information network, a contact chain built key institutions inhabitants continuously monitor howler...
There is a growing concern about the participation of wild hosts and reservoirs in epidemiology several pathogens, particularly within context environmental changes expansion One Health concept. The aim this study was to investigate presence hemoplasmas opossums rescued from metropolitan region Rio de Janeiro state, Brazil. Blood samples were collected 15 Didelphis aurita subjected DNA extraction PCR using primers for 16S rRNA 23S genes. Physical examination hematological analysis also...
Abstract Erlichiosis affects humans and animals worldwide. Its distribution prevalence depends on the presence of tick vectors hosts in one geographic area. The aim present study was to investigate occurrence Ehrlichia spp. Anaplasma opossums (Didelphis sp.) from State Rio de Janeiro, southeast Brazil. Blood samples 37 were tested for these two pathogens using molecular methods. One animal (2.7%) positive sp. by 16S rRNA-based nested PCR. In a phylogenetic analysis based rRNA gene maximum...
Magellanic penguins (Spheniscus magellanicus) routinely migrate from their breeding colonies to Southern Brazil often contracting diseases during this migration, notably avian malaria, which has been already reported in and throughout the world. Detection of Plasmodium spp. blood smears is routine diagnostic method however it a low sensitivity rate when compared molecular methods. Considering negative impact malaria on penguins, aim study was detect presence using Polymerase Chain Reaction...
Abstract Didelphis aurita is an abundant South American didelphid. Chromatic disorders are rare and scarcely known in marsupials. We report describe the occurrence of xanthochromism (yellowish coloration) D. , being first record this anomaly for opossums. The emergence correlated with anthropogenic stress urban-sylvatic interface suggests that chromatic may serve as useful bioindicators health wildlife disturbed environments.
In January 2018, a young male of Didelphis aurita (Wied-Neuwied, 1826), the Brazilian common opossum, was admitted for veterinary evaluation at Recovery Clinic Wild Animals Estácio de Sá University, CRAS, in Rio Janeiro, Brazil, due to presence partially duplicated right hind limb. After x-ray evaluation, polymelia associated with syndactyly diagnosed. The images revealed following alterations on limb: single femur increased diameter, two tibiae, fibulae and absence hallux. observed...
Many emerging infectious diseases are zoonotic and transmitted by an arthropod vector; thus, the Global One Health perspective is necessary for a better understanding of these diseases. Bartonellosis, one those diseases, caused bacteria genus Bartonella, can have different clinical manifestations in humans animals. Opossums their ectoparasites been linked to human-wildlife conflicts. Knowing this, we aimed evaluate infection Bartonella spp. free-living opossums seized or rescued from...
Birds of prey at higher trophic levels are particularly vulnerable to mercury pollution and can serve as indicators trace elements in different ecosystems. Thus, the aim this study was evaluate presence feathers livers some birds that occur State Rio de Janeiro, Brazil. Eleven were collected from pray during routine necropsies performed Janeiro Zoological Garden, animals rehabilitation/release process. The results showed concentrations ranged 0.5 mg / kg 1.3074 0.3376 3.000 feathers. Liver...
Hemoparasitism is known to vary according the presence of vectors and hosts, hematological examination can be a useful tool for early diagnosis in avian medicine, contributing monitoring conservation bird populations. In this context, we aimed analyze clinical aspects free-ranging owls seized or rescued from Atlantic Forest biome Rio de Janeiro, Brazil. The animals, with without signs diseases, were studied regardless their age, sex, physical status. Blood samples collected complete blood...
The genus Fregata includes 5 species, with 3 recorded in Brazil, magnificens being the most abundant. However, its ectoparasitic fauna is still little known. This study aimed to evaluate incidence of ectoparasites F. residing along coast Rio de Janeiro and São Paulo collected by 2 animal rehabilitation centers. Samples were from frigatebirds Instituto Argonauta 10 Centro Recuperação Animais Selvagens (CRAS) Janeiro. Species lice identified using both morphological molecular methods. Scanning...
The brown booby (Sula leucogaster Boddaert, 1783) has a wide geographic distribution, being found throughout the intertropical range except for west coast of South America. Chewing lice (Phthiraptera: Amblycera and Ischnocera) are ectoparasites commonly in association with variety bird species, extensive infestations can lead to severe itching irritation that causes skin lesions, damage plumage, abandonment nests. Sula have an atypical not fully following distribution their host. In years...
Histological studies in wild birds are still incipient, taking into account the great diversity of species and difficulty to obtain material for analysis. Due this scarcity, we aimed describe microscopic lung morphology two terrestrial birds. To do this, used a specimen Ardea alba – Linnaeus, 1758 (great egret) Caracara plancus Miller, 1777 (southern caracara) –, which were taken Center Rehabilitation Wild Animals (CRAS) Universidade Estácio de Sá (UNESA), Vargem Pequena, Rio Janeiro,...
Escherichia coli, an Enterobacterales member, is a normal representative of the microbiota warm-blooded animals. Most strains are commensal, but several pathotypes can cause disease, and numerous antimicrobial resistance factors have been identified. These bacteria spread rapidly in recent years, highlighting importance screening environment non-human reservoirs for virulent and/or those presenting factors, addition to other microorganisms public health importance. In this context, study...
