| A survey was carried out in a hospital of Nova Iguaçu, Rio de Janeiro, Brazil, in the period from July 1999 to March 2002, to determine the infection rate of Listeriamonocytogenes in HIV+ patients with diarrhea symptoms; 134 samples were processed by microbiological methods. The results demonstrated 12.68% of positive samples. However, no statistical differences were observed for age or sex in the studied group, suggesting that this microorganism should be regarded in the differential diagnosis of infectious processes in HIV+ patients in the area. |

| This study aimed to verify the relationship between acute diarrhea provoked by rotavirus and different indicators of craniofacial malformations. In the Hospital for Rehabilitation of Craniofacial Anomalies, 8,724 children with cleft lip and cleft palate were divided into the following groups: acute diarrhea and infection due to rotavirus (C1, n = 62), acute diarrhea (C2, n = 153) and without acute diarrhea (C3, n = 8,509). In C1, 29.03% of the cases consisted of hospital infections associated with the hospitalization period while 38.71% of the patients were aged less than six months. The percentage of children not having breastfed was significantly higher in acute diarrhea groups. Additionally, there was a seasonal prevalence of rotavirus infection between... |

| One hundred and twenty six piglets from a commercial genetic strain weaned at 21 days of age (6.11±0.42 kg) were used to evaluate the effects of supplementation levels of organic sources of trace minerals in the diets of weaned piglets on performance, occurrence of diarrhea, excretion of copper and zinc in the feces, and hematological parameters. A completely randomized block design was adopted, composed of six treatments (diets containing 100% of inorganic trace minerals premix at 3.00 kg/T; diets containing 0, 25, 50, 75 or 100% of organic trace minerals premix, equivalent to 0; 0.75; 1.50; 2.25 or 3.00 kg/T, respectively), seven replicates and three animals per plot. During the experimental period (from 21 to 63 days of age), the increasing levels of... |

| Two hundred pigs (1- 21 weeks old), from five piggeries in São Paulo State, Brazil, were divided in two groups of 100 animals each, G1 with diarrhea and G2 without diarrhea. Campylobacter was recovered from 43% of G1 and 34% of G2 specimens, and was more frequently recovered from 0-4 week old piglets. C. coli was the most common species (44.2% in G1 and 32.4% in G2), followed by C. jejuni/coli (16.3% in G1 and 23.5% in G2). Campylobacter counts were significantly higher in G1 (<FONT FACE="Symbol">£</FONT> 108 UFC/g) than in G2 (<FONT FACE="Symbol">£</FONT> 104 UFC/g) (p < 0.01), which suggests that the bacterium may play a role at least in the aggravation of the diarrheic process. |

| ABSTRACT Two experiments (E) were carried out to evaluate the effects of fumaric acid and an acidifier blend [composed by calcium formate, calcium lactate and medium-chain fatty acids (capric and caprylic)] in piglet diets containing colistin (40 ppm) or halquinol (120 ppm) on performance, diarrhea incidence (E1), organs relative weight, pH values, intestinal morphometry and microbiota (E2). In E1, 192 and E2, 24 piglets weaned at 21-day-old were randomly assigned to blocks with 2x2 factorial arrangement of treatments [absence or presence of fumaric acid x absence or presence of acidifier blend], six replicates of eight (E1) and one piglet per pen (E2). For E1, the treatments were control (CD): no acidifier product + 40 ppm of colistin, FA: fumaric acid in... |

| ABSTRACT The use of hypotonic electrolytic solutions in enteral fluid therapy is still understudied in calves. The objective of the present study was to evaluate the effects of maintenance enteral electrolytic solutions with different concentrations of sodium acetate and different osmolarities in calves. For this, 18 Holstein calves, six male and 12 female, 20 days old and weighing around 52kg, were used. The animals were randomly divided into three groups and each group received one of the treatments. The three electrolytic solutions contained the same components in different concentrations, resulting in a hyposmotic, an isosmotic and a hyperosmotic solution. Each animal was maintained in enteral fluid therapy for 12 hours with infusion rate of 15mL kg-1... |

| Relata-se a quantificação de PCV-2, por meio de PCR em tempo real, no trato gastrintestinal, linfonodo mesentérico, tonsilas e fezes de nove suínos refugo da fase de crescimento, provenientes de rebanhos com histórico de diarreia não responsiva ao tratamento com antibioticoterapia. Com base nos resultados histopatológicos e imunoistoquímicos, os animais foram classificados como afetados por PCV-2 (n=5) e não afetados (n=4). Foi observada diarreia em todos os animais do grupo afetado por PCV-2. Em todas as amostras testadas foi detectado PCV-2, no entanto, a carga viral observada nos tecidos, bem como a excreção nas fezes foi significantemente maior (P<0.01) nos animais com diarreia. A maior concentração de PCV-2 foi observada nos linfonodos... |

| A bacterin from enterotoxigenic Escherichia coli (ETEC), containing fimbriae K99 and F41, was produced and its capacity to induce anti-K99 and anti-F41 antibodies in colostrum of vaccinated cows and in calf serum, and the persistence of these antibodies in neonates were determined. Three experiments were performed on two commercial farms. In all experiments animals were allotted randomly to the blocks, each block consisting of two pregnant females (a vaccinated one and a control one) and their respective calves. In experiment A (farm 1), comprised of 18 blocks, the animals received a vaccine dose 30 days before delivery. In experiment B (farm 1), consisted of 26 blocks, the animals received two vaccine doses (60 and 30 days before delivery). In experiment... |

| One hundred seventy-three Escherichia coli strains isolated from calves from northwestern São Paulo State, having diarrhea were examined for the production of thermolabile (LT) and thermostable (ST) enterotoxins and for the presence of virulence factors associated with bovine colibacillosis. Eighty-five (49.1%) of the E.coli strains produced toxins; 53 isolates were detected as producing STa toxin, and 9 also produced LT toxin. By PCR, 23 isolates were shown to harbor only the LT-II gene. Nine (5.2%) isolates harbored Shiga toxin genes: four carried the stx2 gene, four the stx1 gene and one carried both. Three of the isolates showing stx1 also carried the eae gene. Among the E. coli isolates examined for susceptibility to 10 antimicrobial agents,... |

| The clinical conditions of healthy calves infected with 10(9) CFU of Salmonella Typhimurium were evaluated and the viability of the experimental model in disease induction was verified. Twelve male Holstein calves, 10 to 15-days old, were examined. They were allocated into two groups, control and experimentally infected. Animals were submitted to clinical examination after inoculation and at every 24 hours, during six days after infection. Samples of rectal swabs were collected for Salmonella Typhimurium isolation. Results showed that all animals had different degrees of diarrhea, with mucus and bleeding, 24 to 72 hours after experimental infection with Salmonella Typhimurium, accompanied by fever, but no signs of sepsis. The isolation of Salmonella... |

| ABSTRACT The aim of the present study was to isolate Clostridium perfringens and C. difficile in crab-eating fox (Cerdocyon thous) from Northeastern Brazil. Stool samples of 18 captive crab-eating foxes from four states of Northeastern Brazil (Alagoas, Bahia, Paraíba e Pernambuco) were collected and subjected to C. perfringens and C. difficile isolation. Suggestive colonies of C. perfringens were then analyzed for genes encoding the major C. perfringens toxins (alpha, beta, epsilon and iota), beta-2 toxin (cpb2), enterotoxin (cpe), and NetB- (netB) and NetF- (netF) encoding genes. C. difficile strains were analyzed by multiplex-PCR for a housekeeping gene (tpi), toxins A (tcdA) and B (tcdB) and a binary toxin gene (cdtB). Unthawed aliquots of stool samples... |

| Enteroaggregative Escherichia coli (EAEC) has been implicated in sporadic diarrhea in children and adults and has been identified as the cause of several outbreaks worldwide. The HEp-2 test remains the gold standard for identification of this pathotype. A 60-65 MDa plasmid encodes the aggregative adherence fimbriae (AAF/I and AAF/II), a transcriptional activator ( aggR gene), the enteroaggregative heat-stable enterotoxin EAST1 ( astA gene) and a cytotoxin (Pet). The standard assay for EAEC is performed only in research laboratories, because it is expensive, labor intensive and time-consuming. The Polymerase Chain Reaction (PCR) offers the possibility of rapid diagnosis. In the current study, a multiplex PCR assay which checks aggR and astA genes was... |

| Bovine coronavirus (BCoV) is a known cause of winter dysentery (WD) in adult cattle. The morbidity of the disease is high, that results in a significant decrease in milk production and consequently, economic losses. In the present study, we report on a classical outbreak of WD that affected a high-production Holstein dairy herd raised in a tropical country. The lactating batch included 154 cows, and 138 (90%) presented diarrhea in a short (nine days) period of time. Three (2%) cows died. The other batches of animals did not become ill. The evolution of the disease in the herd, including the clinical signs and epidemiological features, strongly suggested a WD case. Semi-nested PCR and RFLP confirmed that BCoV was the cause of the infection. Samples tested... |
