Resumo: BACKGROUND In Brazil, the Yellow Fever virus (YFV) is endemic in the Amazon, from where it eventually expands into epidemic waves. Coastal south-eastern (SE) Brazil, which has been a YFV-free region for eight decades, has reported a severe sylvatic outbreak since 2016. The virus spread from the north toward the south of the Rio de Janeiro (RJ) state, causing 307 human cases with 105 deaths during the 2016-2017 and 2017-2018 transmission seasons. It is unclear, however, whether the YFV would persist in the coastal Atlantic Forest of RJ during subsequent transmission seasons. OBJECTIVES To conduct a real-time surveillance and assess the potential persistence of YFV in the coastal Atlantic Forest of RJ during the 2018-2019 transmission season. METHODS We combined epizootic surveillance with fast diagnostic and molecular, phylogenetic, and evolutionary analyses. FINDINGS Using this integrative strategy, we detected the first evidence of YFV re-emergence in the third transmission season (2018-2019) in a dying howler monkey from the central region of the RJ state. The YFV detected in 2019 has the molecular signature associated with the current SE YFV outbreak and exhibited a close phylogenetic relationship with the YFV lineage that circulated in the same Atlantic Forest fragment during the past seasons. This lineage circulated along the coastal side of the Serra do Mar mountain chain, and its evolution seems to be mainly driven by genetic drift. The potential bridge vector Aedes albopictus was found probing on the recently dead howler monkey in the forest edge, very close to urban areas. MAIN CONCLUSIONS Collectively, our data revealed that YFV transmission persisted at the same Atlantic Forest area for at least three consecutive transmission seasons without the need of new introductions. Our real-time surveillance strategy permitted health authorities to take preventive actions within 48 h after the detection of the sick non-human primate. The local virus persistence and the proximity of the epizootic forest to urban areas reinforces the concern with regards to the risk of re-urbanisation and seasonal re-emergence of YFV, stressing the need for continuous effective surveillance and high vaccination coverage in the SE region, particularly in RJ, an important tourist location.

Idioma: pt.
Resumo: Este estudo teve como objetivo geral descrever os aspectos ultrassonográficos normais das estruturas do bulbo ocular de primatas da espécie Alouatta fusca, determinando ainda os valores da biometria ocular, e os parâmetros da dopplerfluxometria ocular das artérias oftálmica interna e central da retina. Vinte exames ultrassonográficos oculares foram realizados em dez primatas da espécie Alouatta fusca clinicamente saudáveis, sem sinais de doença ocular ao exame oftalmológico. Procedeu-se a descrição ultrassonográfica das estruturas oculares e posteriormente a biometria foi obtida em quatro distâncias distintas: (D1) correspondentes à câmara anterior, (D2) espessura da lente, (D3) profundidade da câmara vítrea e (D4) comprimento axial do bulbo ocular. Na dopplerfluxometria foram avaliadas as artérias oftálmica interna e central da retina quanto ao índice de resistividade (IR), de pulsatilidade (IP), e as velocidades do pico sistólico (VPS) ediastólica final (VDF). Os valores de biometria foram submetidos a teste de comparação quanto ao gênero dos animais e cortes ultrassonográficos, utilizando o teste t de Student. O mesmo teste foi realizado para comparação dos resultados de dopplerfluxometria entre fêmeas e machos. A descrição ultrassonográfica das estruturas oculares e vascularização do bugio ruivo mostraram-se semelhantes a espécies como o cão, o gato e o homem. Os valores biométricos médios encontrados foram de 2,1±0,38 mm para D1, 3,7±0,30mm para D2, 10,4±0,78mm para D3 e 19,3±1,64mm para D4. Os valores de dopplerfluxometria da artéria oftálmica e da artéria central da retina foram respectivamente: VPS de 25,6cm/s e 14,6cm/s; VDF de 15,8cm/s e 10,7cm/s; IR de 0,7 e 0,5; IP de 1,4 e 0,8.(AU)

This study aimed to describe the sonographic features of normal ocular structures, the ocular biometry and Doppler parameters of the internal ophthalmic artery and central retinal artery of the Alouatta fusca. Twenty ocular ultrasonographic examinations were perform in ten primate species of the Alouatta fusca. Proceeded to the sonographic description of the ocular structures and later biometrics was obtained in four distances: (D1) corresponding to the anterior chamber (D2) lens thickness (D3) vitreous chamber and (D4) axial length of the eyeball. Doppler ultrasound evaluated internal ophthalmic artery and central retinal artery as for the resistivity Index (RI), pulsatility index (PI), peak systolic velocity (PSV) and end diastolic velocity (EDV). The values of biometrics and flowmetry underwent comparison test between genders and sonographic views, by Student t test. The anatomical sonographic description of the ocular structures and vasculature of the red howler were similar to species such as dog, cat and man. The biometric average values found were 2.1±0.38mm for D1, 3.7±0.30mm for D2, 10.4±0.78mm for D3 and 19.3±1.64mm for D4. The Doppler values of the ophthalmic artery and central retinal artery found were: PSV of 25.6cm/s and 14.6cm/s; VDF 15.8cm/s and 10.7cm/s; IR 0.7 and 0.5; IP 1.4 and 0.8.(AU)

Idioma: pt.
Resumo: Os bloqueios regionais vêm sendo explorados e difundidos no dia a dia da medicina veterinária. O presente trabalho relata a execução do bloqueio de plexo braquial em um bugio-ruivo (Alouatta guariba) submetido à amputação de três dígitos. Foi utilizada ropivacaína para o bloqueio, com o paciente sob anestesia geral, com auxílio de neuroestimulador periférico. Quatro horas após a cirurgia e cinco horas após o bloqueio, o paciente não apresentava desconforto ou evitava a manipulação do membro operado e não foram observadas complicações. O bloqueio do plexo braquial é mais comumente utilizado quando se pretende promover analgesia e relaxamento muscular do membro torácico em procedimentos cirúrgicos distais à articulação escápulo-umeral. Há carência em estudos anatômicos sobre diversos primatas, incluindo o bugio-ruivo (Alouatta guariba). Apesar da crescente expansão da clínica de animais silvestres, ainda há lacunas no que diz respeito à execução de técnicas anestésicas em diversas espécies.(AU)

The regional blocks are being exploited and disseminated on a daily basis of veterinary medicine. This study describes the implementation of the brachial plexus block in a red howler-monkey (Alouatta guariba) that underwent amputation of three digits. Ropivacaine was employed for blocking, with the patient under general anesthesia, with the aid of a peripheral nerve stimulator. Four hours after surgery, and five hours after the blockade, the patient had no discomfort nor avoided manipulation of the operated limb and no complications were observed. The brachial plexus block is most commonly used when you want to promote analgesia and muscle relaxation of the forelimb in distal surgical procedures to the scapular-humeral joint. There is a lack of anatomical studies on various primates, including the red howler-monkey (Alouatta guariba). Despite the growing expansion of clinic of wild animals, there are still shortcomings with regards to the implementation of anesthetic techniques in many species.(AU)

Resumo: The capture and quarantine of non-human primates could be necessary in some circumstances including those required under environmental permit. Mortality is undesirable for wildlife management programs and could be related to opportunistic pathogens, for example, deaths due to intestinal protozoa infection outbreaks as described here. Parasitological, necroscopic, microbiological, and molecular tests were used in the diagnosis of severe necrotic enteritis leading to death of three female and two male black howler monkeys (Alouatta caraya) captured and held in quarantine prior to translocation. Parasitological tests showed the presence of cysts of Entamoeba histolytica/dispar (5/5), Entamoeba coli (5/5) and Giardia duodenalis (1/5). Necroscopic assessment revealed areas of severe multifocal necrosis in the intestinal mucosa and submucosa. Histopathological examination revealed the presence of structures morphologically compatible to Entamoeba spp. in all individuals examined. Furthermore, G. duodenalis (1/5) was demonstrated by the nested PCR technique. During temporary captivity of non-human primates in management programs, proper handling protocols, including fast or immediate destination, are suggested in order to mitigate the negative effects of stress and decrease the risk of infections.(AU)

Óbitos por infecções causadas por protozoários intestinais são indesejáveis para programas de manejo de fauna, exigidos no âmbito do licenciamento ambiental e que demandam a captura e quarentena de primatas não humanos. Exames coproparasitológicos, necroscópicos, microbiológicos e moleculares foram utilizados para a confirmação do diagnóstico de uma severa enterite necrótica que levou a óbito três fêmeas e dois machos de Alouatta (A.) caraya capturados e mantidos em quarentena prévia à translocação. Exames coproparasitológicos revelaram a presença de cistos de Entamoeba (E.) histolytica/dispar (5/5), Entamoeba (E.) coli (5/5) e Giardia (G.) duodenalis (1/5). A avaliação necroscópica revelou áreas de necrose multifocal severa na mucosa e submucosa intestinal. A análise microscópica revelou a presença de estruturas morfologicamente compatíveis com trofozoítos do gênero Entamoeba spp. em todos os indivíduos examinados. Além disso, G. duodenalis (1/5) foi demonstrada pela técnica de Nested PCR. Sugere-se que quando for necessário o cativeiro temporário de primatas, deverão ser adotados protocolos de manejo adequados buscando a destinação imediata dos animais, de moto a mitigar os efeitos negativos do estresse e reduzir o risco da ocorrência de infecções.(AU)

Título: Detection of Plasmodium in faeces of the New World primate Alouatta clamitans
Fonte: Mem. Inst. Oswaldo Cruz;111(9):570-576, Sept. 2016. tab, graf.
Idioma: en.
Resumo: Abstract Plasmodium falciparum and Plasmodium vivax have evolved with host switches between non-human primates (NHPs) and humans. Studies on the infection dynamics of Plasmodium species in NHPs will improve our understanding of the evolution of these parasites; however, such studies are hampered by the difficulty of handling animals in the field. The aim of this study was to detect genomic DNA of Plasmodium species from the faeces of New World monkeys. Faecal samples from 23 Alouatta clamitans from the Centre for Biological Research of Indaial (Santa Catarina, Brazil) were collected. Extracted DNA from faecal samples was used for molecular diagnosis of malaria by nested polymerase chain reaction. One natural infection with Plasmodium simium was identified by amplification of DNA extracted from the faeces of A. clamitans. Extracted DNA from a captive NHP was also used for parasite genotyping. The detection limit of the technique was evaluated in vitro using an artificial mixture of cultured P. falciparum in NHP faeces and determined to be 6.5 parasites/µL. Faecal samples of New World primates can be used to detect malaria infections in field surveys and also to monitor the genetic variability of parasites and dynamics of infection.

Idioma: es.
Resumo: Introducción. Colombia es un país con gran diversidad de primates no humanos, entre los cuales se destaca el mono aullador rojo ( Alouatta seniculus ) por su distribución y el papel que desempeña en la presentación de la fiebre amarilla. Objetivo. Describir la coincidencia geográfica del hábitat del mono aullador rojo y la presencia de fiebre amarilla. Materiales y métodos. Se hizo un estudio de carácter descriptivo. Los antecedentes de la fiebre amarilla en Colombia se obtuvieron de los informes y boletines del Instituto Nacional de Salud y del estudio de 2013 de Segura, et al. La presencia de A. seniculus se determinó con base en la plataforma Global Biodiversity Information Facility y el Sistema de Información sobre Biodiversidad de Colombia; los mapas se elaboraron con el programa Diva-Gis, y el modelo de nicho ecológico bajo las condiciones actuales, con el programa Maxent. Resultados. Los departamentos con mayor presencia de A. seniculus fueron Antioquia, Meta y Casanare; en 69,5 % de los departamentos con antecedentes de notificación de fiebre amarilla también había A. seniculus. El modelo de nicho ecológico evidenció que Antioquia, Bolívar, La Guajira, Magdalena, Meta, Santander, Norte de Santander y Vichada tenían porciones de territorio con un índice de probabilidad cercano a 0,9 (90 %). Conclusiones. En 69,5 % de los departamentos con antecedentes de fiebre amarilla se registró la presencia de A. seniculus , lo cual resulta relevante por el papel que los primates no humanos desempeñan como reservorio natural del virus y por su contribución en la presentación de la fiebre amarilla, lo cual les confiere gran utilidad como centinelas.

Introduction: Colombia is a country with an important diversity of non-human primates, of which the red howler monkey ( Alouatta seniculus ) stands out because of its distribution and the role it plays in the occurrence of yellow fever. Objective: To describe the geographic co-occurrence of Alouatta seniculus and the reported presence of yellow fever. Materials and methods: We conducted a descriptive study. The reported presence of yellow fever in Colombia was obtained from the reports and bulletins issued by the Instituto Nacional de Salud , and the study by Segura, et al . (2013). The occurrence of A. seniculus was determined based on the data from the Global Biodiversity Information Facility and the Colombian Biodiversity Information System. A map of the occurrence was developed using the DIVA-GIS program, and the ecological niche model under current conditions was created with the Maxent program. Results: The departments with the highest occurrence of A. seniculus were Antioquia, Meta and Casanare; 69.5% of the departments with reported history of yellow fever had co-occurrence with A. seniculus . The ecological niche model showed that Antioquia, Bolívar, La Guajira, Magdalena, Meta, Santander, Norte de Santander and Vichada had geographical portions with a probability rate nearing to 0.9 (90%). Conclusions: In 69.5% of the departments with a history of yellow fever there was co-occurrence with A. seniculus , which is relevant because non-human primates play a well-known role as natural reservoirs of the virus, and they might contribute to the occurrence of the yellow fever, which makes them very useful as sentinels.

Título: Yellow fever impact on brown howler monkeys (Alouatta guariba clamitans) in Argentina: a metamodelling approach based on population viability analysis and epidemiological dynamics
Fonte: Mem. Inst. Oswaldo Cruz;110(7):865-876, Nov. 2015. tab, graf.
Idioma: en.
Resumo: In South America, yellow fever (YF) is an established infectious disease that has been identified outside of its traditional endemic areas, affecting human and nonhuman primate (NHP) populations. In the epidemics that occurred in Argentina between 2007-2009, several outbreaks affecting humans and howler monkeys (Alouatta spp) were reported, highlighting the importance of this disease in the context of conservation medicine and public health policies. Considering the lack of information about YF dynamics in New World NHP, our main goal was to apply modelling tools to better understand YF transmission dynamics among endangered brown howler monkey (Alouatta guariba clamitans) populations in northeastern Argentina. Two complementary modelling tools were used to evaluate brown howler population dynamics in the presence of the disease: Vortex, a stochastic demographic simulation model, and Outbreak, a stochastic disease epidemiology simulation. The baseline model of YF disease epidemiology predicted a very high probability of population decline over the next 100 years. We believe the modelling approach discussed here is a reasonable description of the disease and its effects on the howler monkey population and can be useful to support evidence-based decision-making to guide actions at a regional level.

Resumo: INTRODUCTION: The aim of the present study was to evaluate the presence of arboviruses from the Flavivirus genus in asymptomatic free-living non-human primates (NHPs) living in close contact with humans and vectors in the States of Paraná and Mato Grosso do Sul, Brazil. METHODS: NHP sera samples (total n = 80, Alouatta spp. n = 07, Callithrix spp. n = 29 and Sapajus spp. n = 44) were screened for the presence of viral genomes using reverse transcription polymerase chain reaction and 10% polyacrylamide gel electrophoresis techniques. RESULTS: All of the samples were negative for the Flavivirus genome following the 10% polyacrylamide gel electrophoresis analysis. CONCLUSIONS: These negative results indicate that the analyzed animals were not infected with arboviruses from the Flavivirus genus and did not represent a risk for viral transmission through vectors during the period in which the samples were collected. .

Resumo: As glândulas adrenais possuem funções endócrinas relacionadas a múltiplas funções vitais, estando intimamente relacionadas à capacidade do animal em se adaptar ao estresse. O exame ultrassonográfico é o método diagnóstico de escolha para avaliação das glândulas em diferentes espécies. Considerando a escassa literatura, questiona-se se as doenças adrenais em primatas não humanos são incomuns ou subdiagnosticadas, havendo a hipótese desse fato ser determinado pela falta de parâmetros. Objetivou-se descrever as características ultrassonográficas das glândulas adrenais para três espécies de primatas não humanos mantidas em cativeiro: Saimiri sciureus (mico-de-cheiro), Aotus azarae infulatus (macaco-da-noite) e Alouatta guariba clamitans (bugio-ruivo). Conclui-se que é possível a identificação das glândulas adrenais por meio de exame ultrassonográfico, sendo que os padrões de referência foram estabelecidos com sucesso para as espécies em questão. Ressalta-se que a adequação de animais em ambientes estressantes é frequentemente acompanhada por uma hipertrofia das glândulas adrenais, portanto deve-se levar em consideração que as mensurações realizadas nesse estudo foram estabelecidas em animais de cativeiro...

The adrenal glands have endocrine functions related to multiple vital functions and are closely related to the animal's ability to adapt to stress. The ultrasound is the diagnostic method of choice for evaluation of glands in different species. Considering the scarce literature, one may question whether the adrenal disorders in nonhuman primates are uncommon or underdiagnosed, and a hypothesis exists that this fact is determined by the lack of parameters. The goal is to describe the sonographic features of the adrenal glands for three species of nonhuman primates kept in captivity: squirrel monkey (Saimiri sciureus), owl monkey (Aotus azarae infulatus) and howler monkey (Alouatta guariba clamitans). It is concluded that it is possible to identify the adrenal glands by ultrasound, and the reference standards have been established successfully for the species in question. It is noteworthy that the adaptation of animals in many stressful environments is often accompanied by a hypertrophy of the adrenal glands, so one should take into account that the measurements performed in this study were established in captive animals...

Título: Plasmodium simium/Plasmodium vivax infections in southern brown howler monkeys from the Atlantic Forest
Fonte: Mem. Inst. Oswaldo Cruz;109(5):641-653, 19/08/2014. tab, graf.
Idioma: en.
Resumo: Blood infection by the simian parasite, Plasmodium simium, was identified in captive (n = 45, 4.4%) and in wild Alouatta clamitans monkeys (n = 20, 35%) from the Atlantic Forest of southern Brazil. A single malaria infection was symptomatic and the monkey presented clinical and haematological alterations. A high frequency of Plasmodium vivax-specific antibodies was detected among these monkeys, with 87% of the monkeys testing positive against P. vivax antigens. These findings highlight the possibility of malaria as a zoonosis in the remaining Atlantic Forest and its impact on the epidemiology of the disease.
