1. ANTICORPOS POLICLONAIS PARA O IMUNODIAGNÓSTICO DE VÍRUS BOVINO
Resumo O objetivo do estudo foi produzir anticorpos policlonais para vírus bovino e testar a reatividade em imunoensaios como imunofluorescência, imunoperoxidase e slot blot. Como imunógeno utilizou-se cepas e/ou isolados dos herpesvírus bovino tipo 1, 2 e 5 (BoHV-1, BoHV-2 e BoHV-5), vírus da diarreia viral bovina (BVDV), vírus respiratório sincicial

2. Isolation of recombinant antibodies directed against surface proteins of Clostridium difficile
Abstract Clostridium difficile has emerged as an increasingly important nosocomial pathogen and the prime causative agent of antibiotic-associated diarrhoea and pseudomembranous colitis in humans. In addition to toxins A and B, immunological studies using antisera from patients infected with C. difficile have shown that a number of other bacterial factors co

3. Sequence analysis of the 5′ third of glycoprotein C gene of South American bovine herpesviruses 1 and 5
Bovine herpesviruses 1 (BoHV-1) and 5 (BoHV-5) share high genetic and antigenic similarities, but exhibit marked differences in tissue tropism and neurovirulence. The amino-terminal region of glycoprotein C (gC), which is markedly different in each of the viruses, is involved in virus binding to cellular receptors and in interactions with the immune system.

4. Effect of mouse antisera targeting the Phlebotomus papatasi midgut chitinase PpChit1 on sandfly physiology and fitness
In sandflies, the absence of the peritrophic matrix (PM) affects the rate of blood digestion. Also, the kinetics of PM secretion varies according to species. We previously characterised PpChit1, a midgut-specific chitinase secreted in Phlebotomus papatasi (PPIS) that is involved in the maturation of the PM and showed that antibodies against PpChit1 reduce th

5. Phlebotomine fauna, natural infection rate and feeding habits of Lutzomyia cruzi in Jaciara, state of Mato Grosso, Brazil
Visceral leishmaniasis (VL) in Brazil is transmitted by the phlebotomine Lutzomyia longipalpis and in some midwestern regions by Lutzomyia cruzi. Studies of the phlebotomine fauna, feeding habits and natural infection rate by Leishmania contribute to increased understanding of the epidemiological chain of leishmaniases and their vectorial capacity.

6. A CssA, CssB and LTB chimeric protein induces protection against Enterotoxigenic Escherichia coli
OBJECTIVES: Enterotoxigenic Escherichia coli (ETEC), a major cause of diarrhea in children under 5, is an important agent for traveler's diarrhea. Heat-labile enterotoxin (LT) and colonization factors (CFs) are two main virulence mechanisms in ETEC. CS6 is one of the most prevalent CFs consisting of two structural subunits viz., CssA, CssB, necessary for a

7. Production of polyclonal antiserum against Cowpea mild mottle virus coat protein and its application in virus detection
Cowpea mild mottle virus (CpMMV), the causal agent of stem necrosis disease, has drawn attention of soybean producers in recent years due to yield losses in the main producing regions of Brazil. Serological methods for viral detection require the use of an antiserum of good quality to achieve specificity and sensitivity. The entire coat protein gene of a Bra

8. Immunologic cross-reactivity between Muscovy duck parvovirus and goose parvovirus on the basis of epitope prediction
Through bioinformatic prediction, between Muscovy duck parvovirus (MDPV) and goose parvovirus (GPV), there were one epitope AA503-509 (RANEPKE) on non-structural protein and three epitopes AA426-430 (SQDLD), 540-544 (DPYRS), 685-691 (KENSKRW) on structural protein might cross-react with each other. Furthermore, the four epitops were expressed in Escherichia

9. Genotypic and phenotypic detection of capsular polysaccharides in Staphylococcus aureus isolated from bovine intramammary infections in Argentina
Staphylococcus aureus (n=157) isolated from intramammary infections in Argentine dairy areas were evaluated for presence of cap5 and cap8 loci. Isolates carrying cap5 and cap8 were serotyped using specific antisera. Sixty four percent of the isolates were genotyped as cap5 or cap8 and 50% of them expressed CP5 or 8.

10. Comparação dos caldos selenito cistina, tetrationato Muller-Kauffmann e Rappaport-Vassiliadis no isolamento de Salmonella Typhimurium
Three selective enrichment broths - selenite cystine (SC), Muller-Kauffmann tetrathionate (MKT) and Rappaport-Vassiliadis (RV) - were compared, for Salmonella Typhimurium isolation from rectal swabs of a calf experimentally infected. The bacteriological procedure involved pre-enrichment in Hajna-GN broth (only for the samples inoculated in RV broth), selecti

11. INVESTIGAÇÃODE Salmonella sp. EM PSITTACIFORMES MANTIDOS EM CRIATÓRIOS COMERCIAIS E CONSERVACIONISTAS DA REGIÃO METROPOLITANA DE FORTALEZA-CEARÁ / RESEARCH Salmonella sp. MAINTAINED IN Psittaciformes in commercial houses and conservationists THE METROPOLITAN REGION OF FORTRESS-CEARÁ
Psittaciformes are the most popular pet birds in the world. Direct contact between humans and Psittaciformes is very comprehensive and the analysis of the bacterial flora of these birds is poorly known, and it can be highly pathogenic. Bacterial infections represent a major cause of enteric diseases in poultry, being the Salmonella one of the main agents inv

12. Tratamento com taurina e interferon beta influencia a expressão do complexo de histocompatibilidade principal de classe I (MHC I) e a formação de sinapses em células PC12 / Interferon beta and taurine treatment induce major histocompatibility complex class I (MHC I) upregulation and synapse plasticity in PC12 cells
It has been demonstrated that MHC I up regulation by exogenous treatment with interferon beta (IFN beta) influences the glial reaction and the synaptic elimination process. Also, the amino acid taurine has been shown to positively influence neuronal survival and plasticity. Nevertheless, the establishment of an in vitro model for studying the synaptic format
