| [acute gastroenteritis due to vibrio parahaemolyticus in spain. presentation of 8 cases]. | eight cases of acute gastroenteritis caused by vibrio parahaemolyticus in humans are described; to our knowledge, they are the first such reported cases in spain. all cases appeared between august 20th and october 15th, with a frequency of 8.3% regarding the overall adult patients with acute gastroenteritis, and 11.5% regarding the overall patients with positive stool culture for any enteropathogenic organism. the eight strains were kanagawa positive and in three patients other enteropathogenic ... | 1989 | 2716372 |
| enterotoxigenic escherichia coli associated with infant diarrhoea in galicia, north-western spain. | to assess the role of enterotoxigenic escherichia coli (etec) in infantile diarrhoea, 482 children with diarrhoea and 103 healthy controls, from three localities of galicia, north-western spain, were investigated between 1985 and 1988. rotavirus (37.3%) and salmonella spp. (12.8%) were the most common causal agents, followed by etec (3.9%), campylobacter jejuni (2.3%), shigella spp. (0.9%) and yersinia enterocolitica (0.5%). etec were significantly more frequently isolated from children with dia ... | 1991 | 1895327 |
| phenotypic and genotypic characterization of salmonella enterica serotype paratyphi b isolates from environmental and human sources in galicia, spain. | salmonella serotype paratyphi b isolates obtained from shellfish and human infections in galicia (northwest spain) from 1998 were investigated by different phenotypic and genetic methods to evaluate their systemic or enteric nature. isolates were investigated for d-tartrate fermentation, presence of genes encoding the effector proteins sope1 and avra, pulsed-field gel electrophoresis profile, and antimicrobial susceptibility. systemic variant strains (dt-) were the dominant among the marine envi ... | 2006 | 16786846 |
| influence of environmental factors and human activity on the presence of salmonella serovars in a marine environment. | the temporal and spatial distribution of salmonella contamination in the coastal waters of galicia (northwestern spain) relative to contamination events with different environmental factors (temperature, wind, hours of sunlight, rainfall, and river flow) were investigated over a 4-year period. salmonellae were isolated from 127 of 5,384 samples of molluscs and seawater (2.4%), and no significant differences (p < 0.05) between isolates obtained in different years were observed. the incidence of s ... | 2004 | 15066800 |
| serotypes, virulence genes, and intimin types of shiga toxin (verotoxin)-producing escherichia coli isolates from human patients: prevalence in lugo, spain, from 1992 through 1999. | we have analyzed the prevalence of shiga toxin-producing escherichia coli (stec) in stool specimens of patients with diarrhea or other gastrointestinal alterations from the xeral-calde hospital of lugo city (spain). stec strains were detected in 126 (2.5%) of 5,054 cases investigated, with a progressive increase in the incidence from 0% in 1992 to 4.4% in 1999. stec o157:h7 was isolated in 24 cases (0.5%), whereas non-o157 stec strains were isolated from 87 patients (1.7%). stec strains were (af ... | 2004 | 14715771 |
| identification of salmonella serovars isolated from live molluscan shellfish and their significance in the marine environment. | a study on the presence of salmonella spp. in live molluscs was performed, which included a description of the different serovars isolated and their relationship to the marine environment. a total of 2,980 samples of shellfish from galicia (n.w. spain) were tested for the presence of salmonella spp. between september 1998 and august 2001. the overall incidence of salmonella was 1.8% and showed a slight rise during the 3 years of the study. mussels and oysters presented a higher incidence than cl ... | 2003 | 12597481 |
| [epidemiology of non-typhoid salmonellosis in a hospital in pontevedra (1994-1997)]. | since data on non-typhoidal salmonellosis in our health care area are scarce, we undertook an epidemiological study covering a four year period (1994-1997). | 2000 | 10905014 |
| [infection by salmonella typhi in the southern area of ponteverde]. | a retrospective study of patients infected by salmonella typhi (st) was conducted in the southern area of pontevedra during a 17-month period in order to assess the clinical and evolutive characteristics and the pattern of antibiotic susceptibility of the infection. st was isolated from samples of 30 patients: 25 hemocultures, 7 coprocultores, 1 urine and 1 aortic aneurysm. nineteen cases had consumed non-sanitary controlled water, 95% from rural areas. the clinical characteristics were similar ... | 1994 | 8193236 |
| [study of a typhoid fever outbreak in baiona (pontevedra)]. | despite of the fact of being a high endemic treat, the notification of a typhoid fever outbreak produces a very unusual epidemiological happening in our province. the uncommon of the sight and the importance of this process has made us focus on this study in order to understand its causes as well as to be able to establish some control according to them. | 1995 | 7497349 |
| [extraintestinal isolation of salmonella in chickens: epidemiologic study of 3 salmonellosis outbreaks after ingestion of raw eggs]. | a taxonomic analysis of the malolactic microflora present in nine grape samples from different zones of galicia, was carried out. nineteen strains were isolated and identified as lactobacillus plantarum (42%), l. brevis (10.6%), l. casei (5.25%), l. hilgardii (5.25%), streptococcus cremoris (5.25%), leuconostoc lactis (5.25%), l. oenos (10.6%), and pediococcus acidilactici (15.8%). | 1987 | 3077329 |
