| vibrios among patients of good socioeconomic conditions during the cholera epidemic in recife, brazil. | between march and july, 1992, we screened for vibrio all fecal samples submitted for bacteriologic diagnosis at a private clinical laboratory in recife. of 1435 cultures examined only 1 (0.07%) was positive for v. cholerae 01, biovar eltor, serovar inaba, but 17 (1.2%) yielded non-cholera vibrio (v. cholerae non-01; v. fluvialis; v. furnissii, v. parahaemolyticus and vibrio spp). thus, v. cholerae 01, differently of other enteropathogenic vibrios, spared individuals of good socioeconomic conditi ... | 1993 | 8115794 |
| [isolation of vibrio cholerae o1 from aquatic environments and foods in pernambuco state, brazil]. | incidence of vibrio cholerae o1 was studied in 2,585 samples from different aquatic environments and 91 from foods in pernambuco state, northeastern brazil, from 1992 to 1994. a total of 193 (7.21%) samples of v. cholerae were isolated with a higher prevalence of the inaba serovar (183-94.8%) than the ogawa serotype (10-5.1%). all isolates were classified as biotype el tor, and resistance patterns to antibiotics showed that all strains were susceptible tetracycline. some 70 random samples of vib ... | 1998 | 9761599 |
| [aeromonas associated with an acute diarrhea outbreak in são bento do una, pernambuco]. | an acute diarrhea outbreak, with 2170 cases, was described during january to july, 2004, in são bento do una, pernambuco. 582 stools were examined and an enteric pathogen was recovered in 25% (145 patients). aeromonas species were the most frequent (114-19.5%) and the main isolates were aeromonas caviae (57-9.8%), aeromonas veronii biovar sobria (23-3.9%), aeromonas veronii biovar veronii (15-2.6%) and other species (19-3.2%). the other isolated enteropathogens were vibrio cholerae o1-ogawa toxi ... | 2006 | 16699653 |
| [the importance of circulating vibriocidal antibodies in a pos-epidemic region of diarrhea, são bento do una, state of pernambuco]. | the levels of vibriocidal antibodies were investigated among 41 adults without any past or present history of diarrhea due to vibrio cholerae o1 who were living in the municipality of são bento do una, pernambuco. a diarrhea outbreak occurred in this locality at the beginning of 2004, involving multiple bacterial agents, including vibrio cholerae. the microtitration test was used to investigate the presence of anti-ogawa and anti-inaba vibriocidal serum antibodies. vibriocidal titers e" 1:640 we ... | 2007 | 18200426 |
| characterization of vibrio cholerae isolated from the aquatic basins of the state of pernambuco, brazil. | through a continuous bacteriological monitoring programme carried out by the health secretariat of the state of pernambuco, brazil, two isolates of vibrio cholerae o1 el tor ogawa were discovered in an endemic area in 2001, during a cholera inactive period, along with six v. cholerae non-o1/non-o139 strains and two aeromonas veronii biovar sobria strains showing an unusual characteristic of agglutination with o1 antiserum. between that time and 2005, eight other o1 isolates were found. the virul ... | 2008 | 18258274 |
| the aquatic environment as a reservoir of vibrio cholerae o1 in hydrographic basins of the state of pernambuco, brazil. | after the worldwide cholera epidemic in 1993, permanent environmental monitoring of hydrographic basins was established in pernambuco, brazil, where cholera is endemic. after a quiescent period, 4 rfbn (serogroup o1) positive water samples that were culture negative were detected by multiplex single-tube nested pcr (mstnpcr); 2 of these were also ctxa (cholera toxin) positive. from may to june 2012, 30 v. cholerae o1 isolates were obtained by culturing samples. these isolates were analyzed for t ... | 2013 | 23533357 |
