The aim of this article is to acquire knowledge about the aspects of snakebite epidemiology in a central region of Brazil. From 1993 to 1995, 90 cases of Crotalinae (Bothrops and Crotalus genera) and two cases of Micrurus snakebite were attended to in a general hospital. Epidemiological information about 73 out of the 90 Crotalinae victims was prospectively(More)
The bushmaster (Lachesis muta) of Central and South America, the world's longest pit viper, is capable of injecting a large dose of potent venom when it bites. A 28-year-old man, bitten by a 1.82 m long L. m. muta in Brazil, developed pain and oedema at the bite site, nausea, vomiting, diarrhoea and sweating. There was peripheral neutrophil leucocytosis and(More)
Aeromonas hydrophila soft-tissue infection has been associated with fish and reptile bites. There have bee three recent cases from Brazil of abscesses complicating snake bites in which A. hydrophila was isolated from the purulent exudates. One of the snakes responsible for the bites was a specimen of Bothrops moojeni, and the others were most probably also(More)
The jararacuçu, one of the most dreaded snakes of Brazil, southern Bolivia, Paraguay and northeastern Argentina, is a heavily-built pit viper which may grow to a length of 2.2 m. Up to 1000 mg (dry weight) of highly-lethal venom may be milked from its venom glands on a single occasion. It has accounted for 0.8% to 10% of series of snake bites in São Paulo(More)
An earlier study in São Paulo state suggested that the dose for patients with mild or moderate envenoming by Bothrops snakes (mainly Bothrops jararaca) could be effectively decreased to 4 ampoules (40 mL) of Brazilian Brothrops polyspecific antivenom. The present 'blinded' study examined the lowest dose studied in the first trial (equivalent to 4 x 10 mL(More)
Less than 10 cases of bites by Philodryas olfersii (Colubridae) have been reported in the literature. In this study, 43 patients admitted to the Instituto Butantan, São Paulo, Brazil, with the diagnosis of P. olfersii bite from 1982 to 1990 were reviewed. The 32 male (74.4%) and 11 female (25.6%) patients presented mainly from November to February (65%).(More)

The accidents were more common in the afternoon, from January to April and from October to December. Ninety nine out of 100 snakes classified as subspecies were(More)

Forty patients with abscesses at the site of Bothrops bite were evaluated. Ten brought the snake responsible for the bite, Bothrops jararaca in all cases. On admission a sample was collected from each case for aerobic and anaerobic culture, and no abscesses drained spontaneously. None of the patients had received antibacterial therapy at this time. The(More)
Data obtained from 515 victims of bites of wolf spiders (family Lycosidae) who were attended in Vital Brazil Hospital, São Paulo City, Brazil, in a 5-year period (1979-1983) were analysed. Bites were more frequent in males (56%). All age groups were involved. Foot and hand were the preferential sites of bite (79%), and pain, generally mild, was the(More)
