Abstract
The aim of this study was to report the occurrence of diarrhea outbreak by Cyclospora cayetanensis in General Salgado Municipality, SP, and the role of the Public Health Laboratory for its elucidation, and posterior monitoring of patients with diarrhea. At Regional Laboratory of Adolfo Lutz Institute in São José do Rio Preto - SP, during the period from August 1999 to December 2002, analyses of samples that came from General Salgado Municipality, SP were carried out. The following assays were performed: 103 water potability analyses, according to American Public Health Association guidelines; 130 coprocultures, including nine examinations for cholera, according to the technique described by Pessoa et al, 1983 and Cholera’s National Commission Manual, 1992; 132 faeces parasitological examinations, including opportunistic agents (by means of autofluorescence assay, alcohol - acid resistant staining by modified Kinyoun technique, formol - ether sedimentation, sporulation by 2.5% potassium dichromate, and Hoffman technique), and 85 virus detection by means of EIARA (m) - Bio Manguinhos/FIOCRUZ, Rio de Janeiro - RJ. Of coproculture examinations, nine (6.9%) were positive for: Shigella boydii, Shigella sonnei, Escherichia coli, O11 and O128, Salmonella Typhimurium, Salmonella Saintpaul, Salmonella Enteritidis, Salmonella Oranienburg, and Salmonella spp (non serotyped). From water samples analyses...
