Integrative taxonomy: combining molecular and morphological characteristics to ...
Ferreira,Ana Paula Pereira Neves; Costa,Andréia Luiza Oliveira; Becattini,Raphael Meira; Ferreira,Mônica Alves Neves Diniz; Paixão,Hugo Pinto Rezende daAbstract Despite the epidemiological importance of the Lymnaeidae family regarding transmission of Fasciola hepatica, knowledge about the diversity and distribution of these molluscs and the role of each species in the expansion of fasciolosis remains sparse. Classical morphological (n=10) identification was performed in lymneids from Lagoa Santa, a municipality in the state of Minas Gerais, Brazil, along with ...
Angiostrongylus minasensis n. sp.: new species found parasitizing coatis (Nasua...
Almeida,Lara Ribeiro de; Souza,Joyce Gonçalves Rosário de; Santos,Hudson Andrade; Torres,Eduardo José Lopes; Vilela,Roberto do ValAbstract Currently, there are 21 species of Angiostrongylus that parasitize the pulmonary or mesenteric arteries of wild and domestic rodents, felids, canids and human. Species of Angiostrongylus have cosmopolitan distribution covering tropical, subtropical and temperate regions. The procyonid Nasua nasua (coati) is a reservoir host for a wide variety of parasites that may be harmful to its populations or may c...
New approaches to studying morphological details of intramolluscan stages of An...
Pereira,Cíntia Aparecida de Jesus; Coaglio,Aytube Lucas; Capettini,Luciano Santos; Becattini,Raphael; Ferreira,Ana Paula Pereira Neves; Costa,AndreiaAbstract Angiostrongylus vasorum is a pulmonary artery parasite of domestic and wild canid. On molluscs, intermediate host, first stage larvae (L1) are found after the first day of infection, in the 8th L2 and in the 30 th L3. It was evaluated L1, L2 and L3 recovered by Baermann technique from Achatina fulica infected with 1000 L1. Fifty larvae/stage were incubated with antibodies anti-β-tubulin, anti-α-tubulin...
Nodular and sclerosing gastritis caused by Cylicospirura felineus in a puma (Pu...
Almeida,Lara Ribeiro de; D’Elia,Mirella Lauria; Sousa,Dyeime Ribeiro de; Joaquim,Jéssica de Souza; Santos,Hudson Andrade; Campos,Bruna HermineAbstract An adult male puma (Puma concolor), hit by a car in an urban area, died three days later despite the therapeutic support provided. At necropsy, multiple firm nodules were identified in the gastric mucosa. The nodules were coated by an intact mucosa with a central opening from which reddish and cylindrical nematodes protruded into the lumen. Twenty-seven nematodes were retrieved for morphological and mo...
Dynamics of haemocytes from Pseudosuccinea columella circulating infected by Fa...
Ribeiro,Vinicius Marques Antunes; Coaglio,Aytube Lucas; Oliveira,Fernando Luiz Pereira; Pereira,Cíntia Aparecida de Jesus; Lima,Walter dos SantosAbstract The lymnaeids are important in the epidemiology of Fasciola hepatica, a neglected and endemic zoonosis. The interaction between the internal defense system of Pseudosuccinea columella and F. hepatica has been little studied. In the present study the effect of infection by F. hepatica on P. columella circulating haemocytes was investigated. Changes in the average number of total circulating haemocytes h...
Occurrence of Fasciola hepatica (Linnaeus, 1758) in capybara (Hydrochoerus hydr...
Dracz,Ruth Massote; Ribeiro,Vinicius Marques Antunes; Pereira,Cintia Aparecida de Jesus; Lima,Walter dos SantosAbstract Fasciola hepatica is a parasite that affects the hepatic ducts of several species of domestic and wild vertebrates, causing huge economic losses to livestock rearing worldwide. Reports on occurrences of F. hepatica in capybaras are an important epidemiological aspect of this disease, since these rodents can be a source of contamination for other animals and humans. In the present study, conducted in a ...
Producción de conidios y clamidosporas de los hongos Duddingtonia flagrans y Mo...
Silva,Manoel Eduardo da; Braga,Fábio Ribeiro; Borges,Luana Alcântara; Oliveira,Paulo de; Lima,Walter dos Santos; Araújo,Jackson Victor deRESUMEN Las especies Duddingtonia flagrans y Monacrosporium thaumasium son micro-hongos considerados promisorios agentes del control biológico de parásitos. Bajo condiciones adversas como la falta de nutrientes, estos hongos producen esporas capaces de sobrevivieren después de pasar por el tracto gastrointestinal de los animales. La formación de estas estructuras es una característica deseable ya que promueve l...
Pathological and parasitological characterization of infection by trematodes (P...
Avelar,Isabela de Oliveira; Silva,Ana Patrícia Carvalho; Gardiner,Chris; Santos,Renato de Lima; Lima,Walter dos Santos; Ecco,RoseleneGross and histological lesions caused by an intestinal parasite were described in three capybaras. The parasites presented a mean length of 14 mm and width of 7 mm, were round to oval or piriform, reddish and pedunculated, and adhered strongly to the mucosa of the large intestine. The intestinal mucosa at the parasite attachment site presented loss of surface epithelium and most glands, with replacement by fibr...
Sicarius uncinipenis and Deletrocephalus cesarpintoi in captive greater rheas o...
Avelar,Isabela de Oliveira; Almeida,Lara Ribeiro de; Santos,Hudson Andrade dos; Lima,Walter dos Santos; Lara,Leonardo Bôscoli; Ecco,RoseleneThe present study details the pathological and parasitological findings of parasitic ventriculitis and nematode infections in the large intestines of two female Rhea americana americana birds. The birds were housed in captivity, and both exhibited poor body condition and lethargy. The rheas were sent to the Veterinary Hospital of the Veterinary School, Universidade Federal de Minas Gerais (UFMG) and, despite me...
Autochthonous infection of buffaloes and cattle by Fasciola hepatica in Minas G...
Dracz,Ruth Massote; Lima,Walter dos SantosFasciola hepatica is a digenetic trematode that parasitizes the bile ducts of different species of vertebrate hosts. In Brazil, this parasitosis is expanding and occurrences have been reported in the southern, southeastern, central-western and northeastern regions. This study aimed to report the first case of naturally infection of buffaloes by this parasite in the state of Minas Gerais. A total of 250 stool sa...
