“…In the state of Minas Gerais, parasite records have arisen in isolation, and new foci have been reported, thus indicating the possibility of emergence of new areas of transmission and spreading of fasciolosis (LIMA et al, 2009;DRACZ & LIMA, 2014).…”

“…In veterinary medicine, it constitutes a serious problem for domestic ruminant rearing and causes large losses and economic harm arising from condemnation of livers in slaughter houses, falls in milk, meat and wool productivity, growth retardation in young animals, decreased fertility, abortions, secondary bacterial infections, death of animals and high costs due to the medication that is used to control the parasitosis (DAEMON & SERRA-FREIRE, 1992;LIMA et al, 2009).…”

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 rural area of the municipality of Confins, Minas Gerais, fresh feces from capybaras were collected from the ground near a lagoon at the edge of the Ribeirão da Mata river. These were examined using the technique of four metal sieves. F. hepatica eggs were recovered. This trematode species was confirmed by observing morphological characteristics and measuring the eggs recovered from the capybara feces, and through experimental infection of Lymnaea columella (Say, 1817) by miracidia from these eggs and subsequent infection of C57/BL06 mice with metacercariae originating from these infected mollusks. The data suggest the occurrence of natural cycle of F. hepatica in this region and provide a warning that expansion of the geographical distribution of this parasite by means of this rodent is possible. It is therefore important to adopting measures for epidemiological control of this helminthiasis.

“…In Brazil, occurrences of this parasite have been reported in the southern, southeastern, central-western and northeastern regions, parasitizing cattle, sheep, buffaloes and wild animals such as coypus and capybaras (SILVA SANTOS et al, 1992;CUNHA et al, 2007;BELLATO et al, 2009;LIMA et al, 2009;CARNEIRO et al, 2010;BENNEMA et al, 2014). Human cases have also been reported in the southern, central-western, southeastern, northeastern and northern regions, with the largest number of cases in the southern and southeastern regions respectively (MAS-COMA et al, 1999;PILE et al, 2000;OLIVEIRA et al, 2007).…”

“…Among these favorable conditions is the presence of snails of the genus Lymnaea, which are intermediate hosts for F. hepatica. Thus, such conditions also include the climatic and environmental factors that provide a suitable habitat for these snails, such as high humidity and adequate temperature and rainfall (LIMA et al, 2009;ALVES et al, 2011;MARTINS et al, 2012).…”

Fasciola 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 samples, 176 from cattle and 74 from buffaloes, from the districts of São José da Lapa and Pedro Leopoldo, were examined. Also, 402 snails of the genus Lymnaea were collected on the same farms and the viability of the eggs from naturally infected buffaloes and cattle and the susceptibility of the snails to infection were tested. A total of 54 animals were found to be positive, 33 cattle (18.75%) and 21 buffaloes (28.37%), and two molluscs showed immature forms of F. hepatica. In experimental infection of specimens of Lymnaea, cercariae were obtained through spontaneous elimination from the 57 th day post-infection onwards. The importance of this first case report can be emphasized because it confirms that this parasite is being dispersed in municipalities in this state that had previously been considered to be unaffected.Keywords: Fasciola hepatica, buffaloes, epidemiology, cattle. ResumoFasciola hepatica é um trematódeo digenético que parasita os ductos hepáticos de diferentes espécies de hospedeiros vertebrados. No Brasil, essa parasitose encontra-se em expansão e a sua ocorrência tem sido descrita nas regiões Sul, Sudeste, Centro-oeste e Nordeste. Esse trabalho objetivou relatar o primeiro caso de búfalos naturalmente infectados no estado de Minas Gerais. Um total de 250 amostras de fezes, sendo 176 de bovinos e 74 de búfalos, provenientes dos municípios de São José da Lapa e Pedro Leopoldo foram examinadas. Também foram coletados 402 moluscos do gênero Lymnaea nas propriedades estudadas e a viabilidade dos ovos oriundos dos búfalos e bovinos naturalmente infectados e a susceptibilidade do molusco a infecção foi testada. Um total de 54 animais apresentavam-se positivos sendo 33 bovinos (18,75%) e 21 bubalinos (28,37%) e dois moluscos apresentaram formas imaturas de F. hepatica. Na infecção experimental dos exemplares de Lymanea, foram obtidas cercarias eliminadas espontaneamente a partir do 57º dia pós infecção. Ressalta-se a importância desse primeiro relato de caso, pois certifica a dispersão do parasito em municípios antes considerados indenes no Estado.

Biological control of Fasciola hepatica eggs with the Pochonia chlamydosporia fungus after passing through the cattle gastrointestinal tract

Fasciolosis is a disease caused by Fasciola hepatica responsible for causing significant losses in livestock. This study aimed to evaluate the Pochonia chlamydosporia fungus (isolate VC1) on F. hepatica eggs after passing through the cattle gastrointestinal tract. For this evaluation, 1 g pellet was given in sodium alginate matrix per kilogram live weight containing 25% of fungal mycelium from isolate VC1 per animal. Twelve animals were used, six treated and six untreated (control). Some stool samples were collected from the groups of treated and control animals, at the times of 12, 18, 24, 48, 72, and 96 h after the pellets' administration. Then, from each stool sample of treated and control groups, 2 g was placed in a Petri dish of 9 cm in diameter, containing 2% water-agar and 1,000 eggs of F. hepatica. It was observed that the fungus was effective in preying upon the eggs in the samples recovered at all of the schedules starting at 12 h. Furthermore, differences were observed (p < 0.01) in the destruction of eggs in the Petri dishes in the treated group compared with the control group. The ovicidal effect was observed after 7 days of interaction. The ovicidal P. chlamydosporia fungus was effective in destroying F. hepatica eggs; therefore, it is suggested that this fungus could be employed as agent for the control of helminth eggs.
