| microbiology of diarrhoea in young beef and dairy calves in argentina. | rotavirus, cryptosporidium sp, and salmonella spp. were investigated in the faeces of 452 diarrhoeic calves from 36 beef and 33 dairy herds. animals surveyed were from a few days of age up to approximately 1 month of life. enterotoxigenic escherichia coli (etec) was studied in 212 calves, aged 15 days or less. the animals were from the provinces of buenos aires (59% of the calves), córdoba (18%), santa fe (16%), entre ríos (5%) and la pampa (2%). a minimum of 4 calves were sampled on each farm. ... | 1990 | 2102011 |
| [salmonella in eviscerated chickens from processing plants of greater buenos aires]. | thirty-five samples of eviscerated poultry from processing plants in greater buenos aires were examined for the presence of salmonella. eighteen samples (51.2%) were found to be contaminated with salmonellae on testing with the non-destructive rinse method. out of 7 plants investigated, 6 exhibited the presence of salmonella in the product. a total of 6 confirmed species were found, s. infantis being the most frequently isolated. rappaport-vassiliadis and tetrathionate-brilliant green broths wer ... | 1983 | 6400768 |
| a new plasmidic cefotaximase from patients infected with salmonella typhimurium. | salmonella typhimurium strains resistant to most beta-lactams, co-trimoxazole, tobramycin and gentamicin were isolated from patients in two hospitals in buenos aires, argentina, beginning in august 1990. the patients were suffering from meningitis, septicaemia or enteritis. therapy including ampicillin, ceftriaxone and gentamicin failed. the strains produced a plasmidic (pmvp-4) extended broad-spectrum beta-lactamase which is more active against cefotaxime than against ceftazidime (vmax for cefo ... | 1992 | 1644493 |
| [serovars of salmonella enterica subspecies enterica and its antimicrobial resistance in slaughterhouse pigs]. | a study was carried out in order to determine the prevalence of salmonella and its serovars among porcine slaughterhouses, to evaluate the antimicrobial resistance profiles and to know the presence of class 1 integrons as possible reservoir of resistance. from a total of 386 samples from four porcine slaughterhouses of buenos aires and santa fe provinces (argentina), 93 (24.1%) salmonella enterica subspecies enterica strains were identified, 52 (55.9%) from cecal contents and 41 (44.1%) from ile ... | 2009 | 19831314 |
| [serotypes of salmonella isolated from the luján river, argentina]. | in this work, the serotypes of salmonella genus polluting the waters of lujan river, situated in the north east of the province of buenos aires, argentina, were studied. a total of 690 samples of water were collected and analysed from february 1988 through december 1989, at three different sites. they were obtained according to the moore technique and then preenriched in buffered peptone water and enriched in rappaport-vassiliadis soya peptone broth was carried out. the isolations were realised ... | 1999 | 10970212 |
| multiply resistant nontyphoidal salmonella gastroenteritis in children. | from january, 1990, to december 31, 1990, 75 children with multiply resistant salmonella gastroenteritis were studied at the children's hospital "ricardo gutierrez" of buenos aires. these children ranged from 1 month to 15 years of age. infection was community-acquired in 20 (26.6%), nosocomially acquired in 50 (66.7%) and undetermined in 5. thirty-nine (52%) had grossly bloody stools. fever occurred at some point in the clinical course in 61 children (81.3%) with a duration of 1 to 33 days (mea ... | 1993 | 8426772 |
