An outbreak of winter dysentery caused by bovine coronavirus in a high-production dairy cattle herd from a tropical country BABT
Takiuchi,Elisabete; Barry,Aline Fernandes; Alfieri,Alice Fernandes; Filippsen,Patrícia; Alfieri,Amauri Alcindo.
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...

Antibiotics for the empirical treatment of acute infectious diarrhea in children BJID
Diniz-Santos,Daniel R.; Silva,Luciana R.; Silva,Nanci.
While the routine use of antibiotics for infectious diarrhea in children must be avoided, because it brings little benefit in most cases and is associated with the risk of increasing antimicrobial resistance, selected cases may require antimicrobial therapy, and the choice of the antimicrobial agent often has to be made empirically. Physicians prescribing antimicrobials in such a setting have not only to be aware of the most likely pathogens, but also of their characteristic antimicrobial susceptibility pattern and the safety profile of the various drugs. We reviewed the literature on the use of ampicillin, beta-lactamase inhibitors, trimethoprim-sulfamethoxazole, chloramphenicol, tetracyclines, nalidixic acid, fluoroquinolones, third-generation...

Antimicrobial susceptibility of Campylobacter sp strains isolated from calves with and without diarrhea in Minas Gerais state, Brazil BJM
Miranda,Karina Leite; Lage,Andrey Pereira.
The antimicrobial susceptibility of 25 Campylobacter sp strains isolated from calves with and without diarrhea - 7 C. coli, 16 C. fetus and 2 C. jejuni was studied by the disk diffusion method. Eleven antimicrobial agents were tested amikacin, ampicillin, kanamycin, chloramphenicol, erythromycin, gentamicin, neomycin, nitrofurantoin, penicillin G, tetracycline and sulfamethoxazole-trimethoprim. All Campylobacter sp strains were susceptible to amikacin, ampicillin, chloramphenicol, erythromycin, gentamicin, neomycin and nitrofurantoin. Three strains were moderately susceptible to kanamycin (2 C. coli and 1 C. fetus). All the strains were resistant to penicillin G. Two C. fetus strains were moderately susceptible to sulfamethoxazole-trimethoprim and 1 C....

Antimicrobial susceptibility of Clostridium perfringens isolated from piglets with or without diarrhea in Brazil BJM
Salvarani,Felipe Masiero; Silva,Rodrigo Otávio Silveira; Pires,Prhiscylla Sadanã; Cruz Júnior,Eduardo Coulaud da Costa; Albefaro,Isabella Silva; Guedes,Roberto Maurício de Carvalho; Lobato,Francisco Carlos Faria.
The minimum inhibitory concentration (MIC) was determined for 13 antibiotics against Clostridium perfringens isolated from Brazilian piglets. The collection of isolates was performed in June to October 2010. All isolates were susceptible to amoxicillin and ceftiofur, whereas most were resistant to tetracycline and lincomycin. Avilamycin and narasin were more effective against isolates from non-diarrheic than from diarrheic piglets. The other antimicrobials were less active in need of high concentrations to inhibit the growth of the C. perfringens type A. These results suggest the need for further studies evaluating molecular factors related to the antimicrobial resistance of C. perfringens.

ApoE polymorphisms and diarrheal outcomes in Brazilian shanty town children. Repositório Alice
ORIÁ, R. B.; PATRICK, P. D.; ORIÁ, M. O. B.; LORNTZ, B.; THOMPSON, M. R.; AZEVEDO, O. G. R.; LOBO, R. N. B.; PINKERTON, R. F.; GUERRANT, R. L.; LIMA, A. A. M..
A series of studies have shown that the heavy burdens of diarrheal diseases in the first 2 formative years of life in children living in urban shanty towns have negative effects on physical and cognitive development lasting into later childhood. We have shown that APOE4 is relatively common in shanty town children living in Brazil (13.4%) and suggest that APOE4 has a protective role in cognitive development as well as weight-for-height in children with heavy burdens of diarrhea in early childhood (64/123; 52%), despite being a marker for cognitive decline with Alzheimer?s and cardiovascular diseases later in life. APOE2 frequency was higher among children with heaviest diarrhea burdens during the first 2 years of life, as detected by PCR using the...

Avaliação clínica da infecção experimental de bezerros com Salmonella Typhimurium Arq. Bras. Med. Vet. Zootec.
Ávila,L.G.; Silva,D.G.; Sato,R.A.; Fagliari,J.J..
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...

Bovine coronavirus detection in a collection of diarrheic stool samples positive for group a bovine rotavirus BABT
Barry,Aline Fernandes; Alfieri,Alice Fernandes; Stipp,Danilo Tancler; Alfieri,Amauri Alcindo.
Neonatal diarrhea is an important cause of economic losses for cattle farmers. The main viral etiologies of enteric diseases are group A rotaviruses (GARV) and the bovine coronavirus (BCoV). Although both viruses infect calves of the same age, the occurrence of mixed infections is still under studied. The present study describes the co-infection of BCoV and GARV in stool samples. Forty-four diarrheic fecal samples from calves up to 60 days old that had previously tested positive for GARV by SS-PAGE were analyzed using semi-nested PCR for BCoV. A product with 251 bp of the BCoV nucleoprotein gene was amplified in 15.9% (7/44) of the samples, demonstrating that co-infection is not an unusual event. These results reinforce the need for testing for both GARV...

Clostridium perfringens: a review of the disease in pigs, horses and broiler chickens Ciência Rural
Silva,Rodrigo Otávio Silveira; Oliveira Junior,Carlos Augusto; Guedes,Roberto Maurício Carvalho; Lobato,Francisco Carlos Faria.
Clostridium perfringens is a gram-positive, anaerobic, fermentative, spore-forming bacillus that may be found in the environment but is more commonly found as part of the microbiota of humans and animals. The bacterium is considered a common enteric pathogen; however, the pathogenesis and predisposing factors of the disease can differ among species. Therefore, specific studies are necessary for understanding the role of this pathogen, how to diagnose it and which control measures are applicable. The aim of this paper is to review the current knowledge regarding C. perfringens infections in pigs, horses and broiler chickens

Comparison of multiplex PCR with serogrouping and PCR-RFLP of fliC gene for the detection of enteropathogenic Escherichia coli (EPEC) BJID
Bouzari,Saeid; Aslani,Mohammad M; Oloomi,Mana; Jafari,Anis; Dashti,Amir.
Enteropathogenic Escherichia coli (EPEC) comprise one of the six categories of diarrhoeagenic E. coli (DEC). EPEC is subgrouped into typical (tEPEC) and atypical (aEPEC). The identification of DEC cannot be based only on cultural and biochemical criteria, since they are indistinguishable from the non-pathogenic E. coli commonly found in human feces. Several PCR methods, with both single and multiple target genes, have been reported for detecting the different DEC pathotypes. In the present study five hundred E. coli isolates from children with diarrhea were subjected into multiplex PCR. Furthermore the strains were typed serologically with O antisera and their fliC gene was characterized by PCR-RFLP. The results obtained revealed that overall 41 (8.2%)...

Cryptosporidium SP in HIV-infected individuals attending a Brazilian University Hospital J. Venom. Anim. Toxins incl. Trop. Dis.
Langoni-Júnior,G.; Souza,L. R..
The aim of the current work was to evaluate the occurrence of Cryptosporidium sp in AIDS patients in a region of São Paulo State, Brazil. Patients were divided into groups according to CD4+ T lymphocyte count and use of potent antiretroviral treatment. Two hundred and ten fecal samples from 105 patients were fixed in 10% formalin and subjected to centrifuge formol-ether sedimentation. Slides were stained with auramine and confirmed by modified Ziehl-Neelsen. Cryptosporidiosis occurrence was 10.5% with no relationship among gender, age or the presence of diarrhea. The number of oocysts in all samples was small, independent of CD4+ T lymphocyte count, HIV plasma viral load, and presence of diarrhea. These results may be due to the reduced prevalence of...
