Evaluation of the possible role of ants (Hymenoptera: Formicidae) as mechanical vectors of nematodes and protists BABT
Villani,Fabio; Morini,Maria Santina de Castro; Franco,Marco Antonio; Bueno,Odair Correa.
Nematodes and protists can be transmitted to humans in many ways and little concern has been given to the mechanical transmission by ants. This study aimed at analysing how the eggs of Ascaris lumbricoides and cysts of Entamoeba coli could be mechanically transmitted to the man by Formicidae. Through the experiments using nests of Tapinoma melanocephalum, Linepithema humile and Monomorium pharaonis reared in the laboratory allied to observations of some 17 ant species in an urban park area in Mogi das Cruzes (SP), it was found that L. humile was capable of carrying eggs of A. lumbricoides both in the field and laboratory conditions (1 worker), as well as was Camponotus rufipes (2), Solenopsis saevissima (1) and Acromyrmex niger (1). The cysts of...

Infecção natural por Entamoeba histolytica Schaudinn, 1903 em Euphractus sexcinctus (tatu) mantidos em cativeiro Arq. Bras. Med. Vet. Zootec.
Soares,C.A.; Oliveira,J.B.; Brito,M.D.C..
Fecal samples of two species of armadillos Euphractus sexcinctus (Xenarthra, Dasypodidae), kept in captivity were analysed by direct and sedimentation methods. Entamoeba histolytica Schaudinn, 1903 and E. coli Grassi, 1879 (Amoebida, Endamoebidae) cysts were observed, the former for the first time in armadillos. This parasitism is worthy of registration in the literature because of the possibility of transmission to the human being when these animals are kept in captivity.

Remoción de formas parasitarias intestinales en una laguna facultativa de estabilización en Lima, Perú Zoologia
Iannacone,José O..
The effectiveness of a waste stabilization pond, to remove intestinal helminth eggs and protozoan cysts was studied in San Martin de Porres, Lima, Peru. From September to October 2000 four collections of samples were performed from raw domestic wastewater and from contends of primary, secondary and tertiary ponds. A comparative study of performance of the concentrations methods of Ritchie and Faust was also done. The overall average removal of parasitic forms was as follow: 69.37% from raw water and primary pond; 48.34% from primary to secondary pond; 85.45% from secondary to tertiary pond and 97.69% from raw water to tertiary pond. There was no significant difference in the quantitative performance of Ritchic and Faust methods. Giardia duodenalis (Lambl,...
