RESUMO

This study describes the pathologic findings of 24 humpback whales (Megaptera novaeangliae) found stranded along the Brazilian coast from 2004 to 2016. Eighteen (75%) animals evaluated were found stranded alive. From these, 13 died naturally on shore and five were euthanized. Six died at sea and were washed ashore. Of the 24, 19 (79.2%) were calves, four (16.7%) were juveniles, and one (4.2%) was an adult. The most probable cause of stranding and/or death (CSD) was determined in 23/24 (95.8%) individuals. In calves, CSD included neonatal respiratory distress (13/19; 68.4%), infectious disease (septicemia, omphaloarteritis and urachocystitis; 3/19; 15.8%), trauma of unknown origin (2/19; 10.5%), and vehicular trauma (vessel strike; 1/19; 5.3%). In juveniles and adult individuals, CSD was: emaciation (2/5; 40%), sunlight-thermal burn shock (1/5; 20%); and discospondylitis (1/5; 20%). In one juvenile, the CSD was undetermined (1/5; 20%). This study integrates novel findings and published case reports to delineate the pathology of a South-western Atlantic population of humpback whales. This foundation will aid in the assessment of the population health and establish a baseline for development of conservation policies.

RESUMO

Abstract Gastrointestinal parasites are important pathogens affecting animals, some of them are of medical and veterinary concern. Although the dynamic of parasitic infections is a complex phenomenon that has been studied under experimental conditions, it shows several gaps in knowledge, especially in insular regions where a confined population of animals and parasites co-exists. In this study was assessed the parasitism by endoparasite gastrointestinal in feral cats (n = 37) and rodents (n = 30) from the Fernando de Noronha Archipelago; in addition, the risk of human infection and ecological implications of these findings were discussed. Out of all samples analysed, 100% scored positive for the presence of gastrointestinal parasites in both feral cats and rodents. A total 17 genera and/or species of endoparasite gastrointestinal were identified, Ancylostoma sp., Strongyloides sp., Trichuris campanula and Toxocara cati were the parasites more frequently in feral cats. In rodents Eimeria sp., Strongyloides sp. and Trichuris muris were parasites more frequently herein detected. Human population living in this area are at risk of parasite infections due to the population of rodents and feral cats in the archipelago.


Resumo Parasitas gastrointestinais são importantes agentes patogênicos que afetam os animais, sendo alguns destes de interesse médico e veterinário. Embora a dinâmica das infecções parasitárias seja um fenômeno complexo que tem sido estudado sob condições experimentais, existem várias lacunas no conhecimento, especificamente em regiões insulares onde existem populações confinadas de animais e parasitas. Neste estudo foi avaliado o parasitismo por endoparasitas gastrointestinais em gatos ferais (n = 37) e roedores (n = 30) do Arquipélago de Fernando de Noronha. Além disso, discutiu-se o risco de infecção humana e implicações ecológicas desses achados. De todas as amostras analisadas, 100% obtiveram resultados positivos para a presença de parasitos gastrointestinais tanto em gatos ferais quanto em roedores. Um total de 17 gêneros e/ou espécies de endoparasitos gastrointestinais foram identificados, Ancylostoma sp., Strongyloides sp., Trichuris campanula e Toxocara cati foram os parasitos mais frequentes em gatos ferais. Em roedores Eimeria sp., Strongyloides sp. e Trichuris muris foram os mais detectados. A população humana que vive nesta área corre o risco de infecções parasitárias, devido à população de roedores e gatos ferais no arquipélago.

RESUMO

The aim of this study was to report the use of an oral combination of ivermectin plus praziquantel in the treatment of a Pulmonicola cochleotrema in an Antillean manatee ( Trichechus manatus manatus). A female manatee was found exhibiting respiratory changes and the presence of parasites in the nares. Based on clinical manifestations presented by the manatee, a symptomatic therapeutic protocol was employed, which included an anthelmintic treatment using a combination of ivermectin plus praziquantel. The parasites retrieved were identified as P. cochleotrema. The fourth day after the onset of the therapeutic protocol, the clinical signs declined and on the seventh day posttreatment no clinical signs were observed. This is the first time a therapeutic protocol of ivermectin plus praziquantel has been used in the treatment of P. cochleotrema in manatees.

RESUMO

The aim of this work was to analyze whether there are differences between the development pattern of Antillean manatee (Trichechus manatus) calves born in captivity and those rescued and kept under rehabilitation. Biometrics data were collected from 1990 to 2010 from 38 calves, 29 of which still had the remnants of the umbilical cord and had been rescued from the Brazilian northeastern coastline (Group I), and nine individuals that were born in captivity and remained with their mothers (Group II). Among the measures obtained through biometry, the total length and weight of the animal were recorded. Given that the breastfeeding of calves occurs approximately until the age of 2 yr, data obtained until the 24th month of life of each individual were evaluated. An average increase in weight of 53.50 +/- 38.54 kg (mean +/- standard deviation [SD]) was detected in Group I and a gain of 106.87 +/- 47.21 kg (mean +/- SD) in Group II. From months 13 to 24, no significant difference in the weight increment was observed. A similar pattern occurred with regard to the increase in the overall length during the first year, where animals from Group I grew 34.81 +/- 17.94 cm (mean +/- SD) and from Group II grew 83.83 +/- 28.21 cm, a statistically significant difference. The growth was not significantly different from 13 to 24 mo. The results found in this study identified the need for a review of the nutritional diet offered to orphaned calves rescued and kept in captivity. The results also support the need for a better adequacy of facilities for these animals as a way to encourage the management strategies adopted for manatee calves maintained in captivity.

RESUMO

Infections by Cryptosporidium spp. in aquatic mammals is a major concern due to the possibility of the waterborne transmission of oocysts. The aim of the present study was to report the occurrence of Cryptosporidium spp. in Antillean manatees (Trichechus manatus) and Amazonian manatees (Trichechus inunguis) from Brazil. Fecal samples were collected and processed using Kinyoun's method. Positive samples were also submitted to the direct immunofluorescence test. The results revealed the presence of Cryptosporidium spp. oocysts in 12.5% (17/136) of the material obtained from the Antillean manatees and in 4.3% (05/115) of the samples from the Amazonian manatees. Cryptosporidium spp. infection was more prevalent in captive animals than in free-ranging specimens.

RESUMO

This study represents the first survey of the parasitic fauna of cetaceans off the northeastern coast of Brazil. Parasites were collected from 82 animals rescued from the states of Ceará to Bahia, including the archipelago of Fernando de Noronha. A total of 14 species of cetaceans were evaluated: Sotalia guianensis, Stenella sp., Stenella clymene, Stenella longirostris, Stenella coeruleoalba, Stenella frontalis, Megaptera novaeangliae, Peponocephala electra, Steno bredanensis, Kogia breviceps, Kogia sima, Globicephala macrorhynchus, Tursiops truncatus, Physeter macrocephalus and Lagenodelphis hosei. The parasites were fixed and preserved in 70% ethanol or alcohol-formalin-acetic acid solution (AFA), clarified in phenol and mounted on slides for morphological identification. In total, 11 species and 8 genera of endo- and ectoparasites were identified: Halocercus brasiliensis, Halocercus kleinenbergi, Stenurus globicephalae, Halocercus sp., Anisakis sp., Crassicauda sp. (Nematoda), Phyllobothrium delphini, Monorygma grimaldii, Scolex pleuronectis, Strobicephalus triangularis, Tetrabothrius forsteri, Tetrabothrius sp., Trigonocotyle sp., Diphyllobothrium sp. (Cestoda), Campula sp. (Trematoda), Bolbosoma sp. (Acanthocephala), Cyamus boopis, Syncyamus pseudorcae and Xenobalanus globicipitis (Crustacea). The identification of some species represented novel records for the country and increased the occurrence of some parasites to new hosts. The use of standardized methodologies for collecting and evaluating a larger number of animals is essential for a better understanding of host-parasite relationships in cetaceans and their use as biological indicators in the region.

RESUMO

A criptosporidiose é uma doença parasitária emergente que vem sendo relatada em diversas espécies de mamíferos, incluindo os aquáticos. Esta revisão trata da epidemiologia da infecção por Cryptosporidium spp. em mamíferos aquáticos. A idade dos animais, dose infectante e o estado imunológico podem influenciar na apresentação clínica, e quando associados a outros patógenos pode levar o animal a óbito. A contaminação dos recursos hídricos constitui um dos principais meios de disseminação do parasito, que foi identificado por diferentes técnicas de análise. A adequação das estruturas de saneamento, utilização de métodos apropriados para a inativação dos oocistos e garantia das normas de higiene pessoal constituem algumas das maneiras recomendadas para minimizar a disseminação do Cryptosporidium entre os mamíferos aquáticos.


Cryptosporidiosis is an emerging parasitic disease that has been related in several mammal species, including the aquatic ones. This review covers the epidemiology infection by Cryptosporidium spp. in aquatic mammals. The age of the animal, infecting dose and immunological state can influence on the clinical presentation, and when associated with other pathogen, can lead the animal to death. The water supply contamination is water supply is one of the major ways of the pathogen dissemination, which was being identified by different techniques of laboratorial analysis. The adequacy of sanitation structures, the use of appropriate method to inactivate the oocysts and the assurance of personal hygiene norms are some of the recommended way to minimize the dissemination of Cryptosporidium among aquatic mammals.

RESUMO

O aumento do tráfego de embarcações motorizadas em áreas utilizadas para alimentação, descanso e reprodução pelos peixes-boi marinhos tem não só afugentado estes animais, mas resultado em potenciais casos de colisões. Este trabalho tem como objetivo relatar casos de interações entre embarcações motorizadas e peixes-boi marinhos (Trichechus manatus) no litoral Nordeste do Brasil. As interações ocorreram nos Estados do Ceará, Paraíba e Sergipe com três espécimes, sendo um destes com quatro registros. Foram observados transtornos clínicos como edema da região frontal, proptose ocular, emagrecimento e múltiplos cortes ao longo do corpo. Sendo assim, o aumento do tráfego de embarcações, e a falta de normativas e de fiscalização que assegurem a efetiva proteção de determinadas áreas, representam um risco direto para a conservação dos peixes-boi marinhos no litoral Nordeste do Brasil.


The increasing traffic of motorboats on feeding, resting and reproduction areas used by manatees causing serious problems for these animals, so scaring them away and leading to potential collisions. The purpose of this study was to describe cases interaction between boat and Antillean manatees (Trichechus manatus) living in the Northeastern coast of Brazil. These interactions took place in the State of Ceará, Paraíba and Sergipe, involving three specimens, one of them with four records. Clinical alterations were observed, such as edema in the frontal part of the body, ocular proptosis, weight loss and multiple cuts all over the body. Therefore, the increasing traffic of motorboats, allied to the lack of normative rules and effective law enforcement assuring the protection of specific areas, represent a direct risk to the conservation of Antillean manatees living in the Northeastern coast of Brazil.
