| treated-cured indeterminate leprosy: a search for predictive histopathological and immunohistochemical parameters in skin biopsies taken from patients at admission and at clinical discharge. | in a previous study an index (sigma 3) resulting from the summation of three parameters, i.e., presence of bacilli, even in small numbers, in various dermal structures, multiple positive antigen sites as detected by anti-bcg antiserum and dermal nerve involvement, identified 72.22% of cases of indeterminate leprosy which progressed to multibacillary leprosy. the present study was undertaken to investigate possible parameters which might be indicative of indeterminate leprosy which would persist ... | 1992 | 1293916 |

| prevalence of colonization factor antigens (cfas) and adherence to hela cells in enterotoxigenic escherichia coli isolated from feces of children in são paulo. | fifty-eight enterotoxigenic escherichia coli (etec) strains, isolated from children with and without diarrhea in são paulo, were examined for the presence of colonization factor antigens (cfas) and their ability to adhere to hela cells. antisera to cfa/i, the coli surface (cs) antigens cs1cs3, cs2cs3, and cs2 of cfa/ii, cfa/iii, and cs5cs6 and cs6 of cfa/iv were used. cfas were identified in 43% of the etec strains: 40% of the cfas strains with cfas harbored cfa/i, 24% carried cfa/ii (cs1cs3), 2 ... | 1994 | 7854210 |
| potentially pathogenic vibrios associated with mussels from a tropical region on the atlantic coast of brazil. | mussels (perna perna) harvested on the coast of ubatuba, in three different stations in the state of são paulo, brazil, were examined for vibrio spp. over a 1 year period. the ranges of most probable number (mpn 100 g-1) were: vibrio alginolyticus (< 3-24,000), v. parahaemolyticus (< 3-24,000), v. fluvialis (< 3-1100), v. cholerae non-o1 (< 3-23), v. furnissii (< 3-30), v. mimicus (< 3-9) and v. vulnificus (< 3-3). the highest incidence was observed for v. alginolyticus (92-100%), followed by v. ... | 1994 | 7989253 |
| biochemical, antigenic and allergenic characterization of crude extracts of drechslera (helminthosporium) monoceras. | in a previous study with airborne mould extracts we verified that drechslera (helminthosporium) monoceras presented stronger reactions than those presented by 42 other moulds isolated in são paulo city. in the present study, we evaluated the biochemical composition and the antigenicity of crude extracts obtained from vegetative and conidial stage of d. monoceras using czapeck broth (cb) modified and tris-hcl for extraction. the maximum values of total proteins and lipids were verified in the cru ... | 1995 | 8532058 |
| the acute toxicity of riedeliella graciflora in laboratory animals. | riedeliella graciflora is a plant mainly found in southeast south america and related to bovine mortality in sao paulo state, brazil. our laboratory showed that cattle intoxicated with 10 g r graciflora leaves/kg had organ congestion, edema and hemorrhage. the aim of this study was to determine which laboratory animal species would present the same lesions found in cattle. we also studied the effects of administering parts of the fruits or leaves po, sc, ip or im. all the laboratory species deve ... | 1995 | 8588292 |
| [analysis of human anti-rabies post exposure treatment in the great area of sao paulo, brazil]. | the treatment of human beings with risk of exposure to rabies virus infection still presents some cases of undesirable post treatment reactions. the knowledge resulting from the regular analysis of the epidemiological features associated with these practices would minimize the occurrence of these troubles. | 1999 | 10457003 |
| serobiotypes and virulence genes of escherichia coli strains isolated from diarrheic and healthy rabbits in brazil. | a total of 178 escherichia coli isolates from diarrheic and healthy rabbits in the são paulo state (brazil) were serobiotyped and investigated by pcr for the presence of virulence genes. among the 90 (50.6%) isolates which possessed the eae gene, 74 were from diarrheic animals and all but one encoded intimin beta. sixty five (72.2%) of the eae+ isolates had insertion of the locus of enterocyte effacement locus in the pheu locus, 11 (12.2%) in the selc and 14 (15.6%) did not insert in either of t ... | 2002 | 12223161 |
| analysis of the toxic potential of venom from loxosceles adelaida, a brazilian brown spider from karstic areas. | loxosceles adelaida spiders (araneae, sicariidae) are found near and inside the caves in the parque estadual turistico do alto ribeira (petar), sao paulo, brazil, which are visited by thousands of tourists every year. several loxosceles species are a public health problem in many regions of the world, by causing severe dermonecrosis and/or complement dependent haemolysis upon envenomation. the aim of this study was to characterize the biochemical and biological properties of l. adelaida venom an ... | 2005 | 15733566 |
