[Giardiasis and cryptosporidiosis in children institutionalized at daycare centers in the state of São Paulo].

Two cross-sectional studies were conducted, in 2002 (N=379) and 2003 (N=397), to estimate the prevalence of intestinal parasites among children at five municipal daycare centers in Botucatu, State of São Paulo. Socioeconomic, sanitary and educational data were collected and parasitological tests were performed on feces. Giardia duodenalis presented prevalence of 23.

Occurrence of enteroparasites in day care centers in Botucatu (São Paulo State, Brazil) with emphasis on Cryptosporidium sp., Giardia duodenalis and Enterobius vermicularis.

The occurrence of the enteroparasites was verified in 279 children (0 to 6 years) of four municipal day cares of Botucatu/SP. Three samples of each child's feces were collected and processed by the methods of Hoffman-Pons-Janner, Faust and Ritchie and subsequent coloration of the fecal smear by the methods of Auramina-O and Ziehl-Neelsen modified for diagnosis of Cryptosporidium sp. and Graham method for diagnosis of Enterobius vermicularis.

[Phlebotominae (Diptera: Psychodidae) in area of transmission of american tegumentar leishmaniasis in the north coast of the State of São Paulo, Brazil].

Fourteen, 30 and 104 cases of American tegumentary leishmaniasis were recorded respectively, in 1993, 1994 and 1995, in the coast region of São Paulo State. Aiming to characterize the fauna and seasonal and hourly distributions of the phlebotominic species, adult specimens were captured fortnightly between November/95 and December/96. CDC light traps were used as of dusk intradomiciliarly, peridomiciliarly and in the forest for 12 hours.

Occurrence of Cryptosporidium (Apicomplexa, Cryptosporidiidae) in Crotalus durissus terrificus (Serpentes, Viperidae) in Brazil.

The objective of the present study was to investigate the prevalence of Cryptosporidium (Apicomplexa, Cryptosporidiidae) in the snake Crotalus durissus terrificus (Serpentes, Viperidae). Fifty animals were evaluated for the presence of oocysts of Cryptosporidium sp. at the time of arrival and 30 and 60 days later.

Thermal constant of an experimental population of Muscina stabulans (Fallén 1817) (Diptera:Muscidae) in the laboratory.

A study was conducted to investigate the thermal constant in an experimental population of Muscina stabulans (Fallén 1817). A natural population was obtained from a livestock and their F1 generations were maintained at four constant temperatures (16 degrees C, 20 degrees C, 26 degrees C and 31 degrees C). The thermal constant was calculated by the hyperbole method using the base temperature, tb = 4.
