Evaluation of Kato-Katz and spontaneous sedimentation methods for the diagnosis...
Mati,Vitor Luís Tenório; Pinto,Hudson Alves; Melo,Alan Lane dePlatynosomiasis is a parasitic infection reported in non-human primates, including marmosets, and is frequently difficult to diagnose. In this study, the Kato-Katz method and the spontaneous sedimentation method were evaluated for their usefulness in identifying Platynosomum eggs in fecal samples from Callithrix penicillata that naturally harbor Platynosomum illiciens. Spontaneous sedimentation allowed the diag...
Toxocara cati (Nematoda: Ascarididae) in Didelphis albiventris (Marsupialia: Di...
Pinto,Hudson Alves; Mati,Vitor Luís Tenório; Melo,Alan Lane deEggs of Toxocara cati were found in the feces of Didelphis albiventris from a peridomestic urban environment in Brazil. Negative fecal tests following short-term captivity of the opossums, as well as the absence of ascaridids during necropsy, suggest the occurrence of pseudoparasitism. Implications of the findings for the epidemiology of toxocariasis are discussed.
The Pampulha reservoir remains a potential urban focus of schistosomiasis manso...
Pinto,Hudson Alves; Mati,Vitor Luis Tenorio; Melo,Alan Lane deIntroduction The Pampulha reservoir has long been a focus of schistosomiasis transmission in Belo Horizonte, State of Minas Gerais, Brazil. The last malacological study conducted in this urban reservoir was more than two decades ago, and thus, an update on the distribution of the species of Biomphalaria as well as new data on the presence of Schistosoma mansoni in this water body are required. Methods The curre...
Petasiger Dietz, 1909 (Trematoda: Echinostomatidae) in Birds and Mollusks from ...
Pinto,Hudson Alves; Mahecha,Germán Arturo Bohórquez; Melo,Alan Lane deSpecies of Petasiger Dietz, 1909 are intestinal trematodes of aquatic birds. Despite the diversity of described species in Europe and North America, only two South American species are known and no species have been previously reported in birds from Brazil. During a study of helminths recovered from the Least Grebe, Tachybaptus dominicus(Linnaeus, 1766), from the state of Minas Gerais, Brazil, adult trematodes ...
Trypanoxyuris (Paraoxyuronema)lagothricis (Nematoda: Oxyuridae) in Lagothrix ca...
Pinto,Hudson Alves; Ferreira Junior,Francisco Carlos; Mati,Vitor Luís Tenório; Melo,Alan Lane deDuring necropsy of a specimen of Lagothrix cana (É. Geoffroy, 1812) (Primates: Atelidae) from the Brazilian Amazon, pinworms were found in the large intestine. The intensity of infection was 64 parasites (17 males and 47 females) and there were no gross pathological changes related to parasitism. After morphological analysis the parasites were identified asTrypanoxyuris (Paraoxyuronema)lagothricis (Buckley, 193...
Metacercariae of Centrocestus formosanus (Trematoda: Heterophyidae) in Australo...
Pinto,Hudson Alves; Melo,Alan Lane deHeterophyid metacercariae were found in the gills of Australoheros facetus (Jenyns, 1842) collected from the Pampulha reservoir, Belo Horizonte, Minas Gerais, Brazil, between February and April 2010. The cysts were counted and used to perform experimental studies (artificial excystment and infection of mice). Fifty specimens of A. facetus were analyzed and it was found that the prevalence of infection was 100% ...

Braga,Fabio Ribeiro; Araujo,Juliana Milani; Silva,André Ricardo e; Araújo,Jackson Victor de; Carvalho,Rogério Oliva; Tavela,Alexandre de OliveiraINTRODUÇÃO: Strongyloides venezuelensis tem sido utilizado como um modelo para estudo da estrongiloidose humana. MÉTODOS: O objetivo deste trabalho foi comparar a capacidade predatória dos fungos nematófagos Duddingtonia flagrans (AC001), Arthrobotrys robusta (I-31) e Monacrosporium sinense (SF53) sobre larvas infectantes (L3) de Strongyloides venezuelensis em condições laboratoriais no meio ágar-água 2%.

Suscetibilidade de larvas de Culex quinquefasciatus a diferentes inseticidas
Alves,Stênio Nunes; Tibúrcio,Jacqueline Domingues; Melo,Alan Lane deINTRODUÇÃO: O presente estudo teve como objetivo avaliar a suscetibilidade de larvas de Culex quinquefasciatus a dois piretróides (Cipermetrina e Deltametrina), dois derivados da Avermectina (ivermectina e abamectina) e a um organofosforado (Temefós). MÉTODOS: Larvas de 3º e 4º instares de C. quinquefasciatus foram expostas a diferentes concentrações destes (onze repetições) seguindo o protocolo da Organização ...
Metacestodes of Glossocercus auritus (Cyclophyllidea, Gryporhynchidae) in Poeci...
Pinto,Hudson Alves; Melo,Alan Lane deStudies on fish parasites in Pampulha dam, Belo Horizonte, Minas Gerais, Brazil, found specimens of Poecilia reticulata Peters, 1859 harboring natural infection by larval stages of tapeworms. A total of 250 specimens of P. reticulata were collected and analyzed between February and August 2010, of which 23 were found infected (prevalence 9.2%) with one metacestode each (mean intensity 1, mean abundance 0.09). T...

Pereira,Domingos L. V.; Melo,Alan Lane deA list of aquatic and semiaquatic Heteroptera from a collecting trip to Pitinga, a village in a mining area in the County of Presidente Figueiredo in the Central Amazon is presented. Identified were fifty five species of Heteroptera, distributed in 13 families.
