| [the absence of yersinia enterocolitica in foods and animal reservoirs in areas of the state of pernambuco, brazil]. | a search for the presence of enteropathogenic bacteria in fresh vegetables obtained in 5 restaurants from the city of recife, revealed neither yersinia enterocolitica nor other pathogenic bacteria in 96 samples analyzed. furthermore, y. enterocolitica was not found in the oral and rectal swabs taken from 15 apparently healthy pigs at an abattoir in the municipality of bonito in the pernambuco state. another search in which twenty one rodents from four species and one marsupial specimen were exam ... | 1997 | 9273565 |
| detection of lawsonia intracellularis in faeces of swine from the main producing regions in brazil. | swine proliferative enteropathy is an enteric disease caused by lawsonia intracellularis which affects animals between 6 and 20 weeks of age, causing diarrhea, anorexia, and poor growth. the presence of l. intracellularis was evaluated in the faecal samples of 636 swine from 75 randomly chosen herds in the main swine-producing regions of brazil. the pathogen was detected by the polymerase chain reaction method (pcr) using l. intracellularis specific primers. a 319-bp dna fragment specific for l. ... | 1999 | 10408095 |
| description of males of parabronema pecariae ivaschkin, 1960 (nematoda, habronematoidea) parasitizing peccaries (mammalia, tayassuidae) in brazil. | nematodes studied herein and identified as parabronema pecariae were collected in 1936 in the states of rio de janeiro and pará and in 1940 in the state of mato grosso do sul, brazil. this species was proposed, with basis on female specimens that had been described earlier as parabronema sp. although the presence of males of p. pecariae was previously reported in brazil, their description was not provided. the present paper deals with the first complete morphometric data on male specimens of p. ... | 2000 | 11080772 |
| g and p genotypes of group a rotavirus strains circulating in calves in brazil, 1996-1999. | fifty fecal samples from calves with diarrhea, positive for group a rotavirus by enzyme immunoassay (eia) and polyacrylamide gel electrophoresis (page) were analyzed by a nested multiplex reverse transcription/polymerase chain reaction (nested multiplex/rt-pcr) for identification of p and g genotypes. samples were collected between 1996 and 1999 from eight dairy and/or beef cattle herds located in the mato grosso do sul, são paulo, goiás and paraná states, brazil. complete genotyping was possibl ... | 2004 | 15066719 |
| seroprevalence of toxoplasma gondii infection in swine matrices in nova mutum and diamantino, mato grosso, brazil. | this report aimed to assess the seroprevalence of toxoplasma gondii infection in 708 swine matrices in nova mutum and diamantino in the state of mato grosso, central-west brazil. serum samples were examined by indirect fluorescent antibody test (ifat). it was found a seroprevalence of 12.8%, considering titers ≥ 64. therefore, the data reinforce the need for appropriate management of swine raising to minimize the risk of infection of pigs with t. gondii. | 2010 | 21184704 |
| prevalence of enterotoxigenic and shiga toxin-producing escherichia coli in pigs slaughtered in mato grosso, brazil. | this study aimed to estimate the prevalence of enterotoxigenic escherichia coli (etec) and shiga toxin-producing escherichia coli (stec) strains in pigs slaughtered in abattoirs located in the state of mato grosso, brazil. | 2011 | 21389592 |
| epidemiological factors related to the transmission risk of trypanosoma cruzi in a quilombola community, state of mato grosso do sul, brazil. | this work was an epidemiological investigation of the risk of trypanosoma cruzi transmission in the rural quilombola community of furnas do dionízio, state of mato grosso do sul, brazil. | 2011 | 22031072 |
| genetic characterisation of porcine circovirus type 2 (pcv2) strains from feral pigs in the brazilian pantanal: an opportunity to reconstruct the history of pcv2 evolution. | since its discovery, porcine circovirus type 2 has emerged as one of the most relevant swine infectious diseases, causing relevant economic losses for the pig industry. while four genotypes were identified, only three (pcv2a, pcv2b and pcv2d) are currently circulating and display a worldwide distribution. another genotype, pcv2c, has been described only once in danish archive samples collected between 1980 and 1990. in addition to commercial pigs, pcv2 has been demonstrated to infect wild boars ... | 2015 | 25975522 |
| serological and molecular investigation of the prevalence of aujeszky's disease in feral swine (sus scrofa) in the subregions of the pantanal wetland, brazil. | the feral swine (fs) originated from the domestic pig and is present throughout the brazilian wetland plain (the pantanal). aujeszky's disease (ad) was first serologically confirmed in the state of mato grosso do sul (ms) in 2001; however, there was no viral confirmation. the aim of this study was to investigate antibodies against-suhv-1 in the sera of feral swine in the studied areas, detect suhv-1 through pcr and classify the viral genome. among the 218 animals sampled, 186 were analyzed by el ... | 2013 | 23639473 |
| ochratoxin a in serum of swine from different brazilian states. | the aims of the current study were to monitor the presence of ochratoxin a (ota) in the serum of slaughtered swine and to investigate its distribution in 4 major geographical regions of brazil. a total of 400 samples of serum were collected from 4 major states of brazil (100 samples each). ochratoxin a concentrations were determined by high-performance liquid chromatography. in santa catarina state, 60% of the samples had ota concentrations ranging from 4.01 to 75.4 mg/l. in mato grosso state, 7 ... | 2010 | 20807935 |
| animal cysticercosis in indigenous brazilian villages. | sanitary inspection of beef and pork meat has been the major tool for diagnosing animal cysticercosis and for preventing taeniasis in brazil. the indigenous villages jaguapiru and bororo are located close to the urban area of the municipality of dourados in the state of mato grosso do sul, brazil, where precarious basic sanitation conditions are observed. both cattle and pigs are raised for self-consumption of meat and milk as well as for sale on the external market, generally without official s ... | 2010 | 20624354 |
| observations on the feeding habits of lutzomyia longipalpis (lutz & neiva, 1912) (diptera: psychodidae: phlebotominae) in campo grande, an endemic area of visceral leishmaniasis in mato grosso do sul, brazil. | sand flies were captured weekly with cdc light traps from december 2003 to november 2005 in three areas of campo grande, in the brazilian state of mato grosso do sul. these areas incorporated two patches of remnant forest and five houses. the blood meals of engorged female sand flies were identified using the avidin-biotin system of immunoenzymatic elisa capture. most (327/355) of the females analysed were lutzomyia longipalpis, of which 66.4% reacted with human blood, 64.8% with that of birds a ... | 2008 | 18611387 |

| detection of pneumocystis spp. in lung samples from pigs in brazil. | the genus pneumocystis is composed of opportunistic fungi currently considered as specific pulmonary pathogens in humans and other mammals. in pigs, pneumocystis pneumonia (pcp) could create significant economical losses due to its detrimental effects on growth, food conversion, and carcass/viscera condemnation. this study revealed that pneumocystis organisms could be detected by grocott's staining or immunohistochemistry in 36.9% of 564 slaughtered pigs from two geographic regions of brazil. th ... | 2007 | 17654265 |
| naturally acquired infections with leishmania enriettii muniz and medina 1948 in guinea-pigs from são paulo, brazil. | two domestic guinea-pigs (cavia porcellus), bought in pinheros, são paulo state, brazil, were taken by their owners to a farm in the rural district of capão bonito, close to the atlantic forest, são paulo, where they both developed tumour-like and ulcerating lesions on the ears. the causative agent was identified as leishmania (l.) enriettii, based on biological characters and isoenzyme profiles. sources of the parasite in wild mammals, and the possible sandfly vector species are discussed. | 1994 | 8084659 |
