1. Occurrence of Mycobacterium avium subsp. paratuberculosis in coalho cheese in the State of Pernambuco, Brazil
RESUMO Paratuberculose é uma enfermidade crônica e incurável que acomete ruminantes e outras espécies de animais domésticos. É causada pelo Mycobacterium avium subsp. paratuberculosis (MAP) e ainda há a suspeita do seu envolvimento em enfermidades nos humanos como a doença de Crohn, diabetes tipo 1, sarcoidose, esclerose múltipla e tireoidite de Has

2. Concentrations of acute-phase proteins and immunoglobulins in serum and synovial fluid in clinically healthy heifers and steers
RESUMO: O objetivo do estudo foi determinar o padrão de concentração de proteínas de fase aguda e de imunoglobulinas intra-articulares (APPs) em bovinos mestiços saudáveis. As amostras de fluido sinovial (SF) foram coletadas da articulação radiocárpica de 25 novilhas e 25 novilhos. As concentrações de APPs foram mensuradas por SDS-PAGE. Os resulta

3. Traceability of animal protein byproducts in ruminants by multivariate analysis of isotope ratio mass spectrometry to prevent transmission of prion diseases
Abstract Background: Ruminant feed containing animal byproduct proteins (ABPs) is prohibited in many countries due to its risk of transmitting prion diseases (PD). In most cases the entire herd is sacrificed, which causes great harm to the producer countries by preventing their exportation of ruminant derived-products. Methods: We used stable isotope ratio

4. Efficacy, toxicity, and lethality of plants with potential anthelmintic activity in small ruminants in Brazil
RESUMO A utilização de plantas medicinais como método terapêutico no controle de enfermidades tem sido crescente na produção animal. No caso de pequenos ruminantes, as verminoses representam uma grande preocupação, visto que são consideradas o maior problema sanitário, especialmente quando se considera o fenômeno da resistência dos parasitas aos

5. POLIOENCEFALOMALACIA EM RUMINANTES / POLIOENCEPHALOMALACIA IN RUMINANTS
In the first portion of this thesis, epidemiology, clinical signs and distribution of lesions in the brain of thirty one cases of polioencephalomalacia (PEM) in cattle from the Southern (13 cases) and Midwestern (18 cases) Brazil were studied. Morbidity (0.04%-6.66 %), mortality (0.04%-6.66 %), and lethality (50%-100%) rates were similar in both regions stud

6. Association between MUC1 gene polymorphism and expected progeny differences in Nelore cattle (Bos primigenius indicus)
MUC1 is a heavily glycosylated mammalian transmembrane protein expressed by mucosal secretory tissues for both protection against microbial infection and lubrication. An important characteristic of MUC1 is its variable number of tandem repeats (VNTR) containing several sites for O-glycosylation. VNTR length has been associated with many human diseases and wi

7. Mycoplasmosis in cattle dairy calves: underlying factors for the occurrence and manifestation of the syndrome granular vaginitis / Micoplasmose em bovinos de aptidão leiteira: fatores predisponentes para a ocorrência e manifestação da síndrome vulvovaginite granular
The reduction of reproductive rates is measured by the reduction in the number of calves born that immediately reflected in the reduction of milk production and profitability of commercial property. The effect is the increased administrative costs of maintenance with dry cows, higher rates of rejection and a higher number of doses of semen for conception. Pa

8. Isolamento de ureaplasma e micoplasma do trato reprodutivo de ovinos e caprinos e tipificação genotípica por meio da PFGE e seqüenciamento do gene 16S rRNA / Isolation of ureaplasma and mycoplasma from reproductive tract of sheep and goats and genotypic typification by PFGE and 16S rRNA gene sequencing
Mycoplasmas and or ureaplasmas have been isolated from small ruminants but are few studied. Mycoplasma ovine/caprine serotype 11, known as 2D strain, has not been classified yet as specie. However, it has been associated to vulvovaginitis and reproductive disorder in caprine and ovine. Ureaplasmas may cause genital tract diseases. Experimental infections wit

9. Recovery and Characterization of a Chimeric Rinderpest Virus with the Glycoproteins of Peste-des-Petits-Ruminants Virus: Homologous F and H Proteins Are Required for Virus Viability
Rinderpest (RP) and peste-des-petits-ruminants (PPR) are two important diseases of domestic ruminants. To improve on currently available vaccines against PPR, we have created cDNA copies of the RP virus genome in which either the fusion (F) or hemagglutinin (H) gene, or both, was replaced with the corresponding gene from PPR virus. It was necessary to develo

10. The tribe Ehrlichieae and ehrlichial diseases.
The tribe Ehrlichieae consists of gram-negative minute cocci that are obligate intracellular parasites classified in the family Rickettsiaceae. Although ehrlichial organisms have been observed in leukocytes for many years, only a few species have been cultured in quantities sufficient for biochemical and molecular analyses. Recents studies on 16S-rRNA sequen

11. Intestinal multiplication of Mycobacterium paratuberculosis in athymic nude gnotobiotic mice.
In this study gnotobiotic mice were inoculated with a human isolate of Mycobacterium paratuberculosis (strain Linda; ATCC 43015) in an attempt to investigate the pathogenesis of intestinal paratuberculosis. Mycobacterium paratuberculosis-monoassociated nu/+ mice developed a persistent low-level intestinal infection but did not support progressive bacillary m

12. Antigen Capture Competitive Enzyme-Linked Immunosorbent Assays Using Baculovirus-Expressed Antigens for Diagnosis of Bluetongue Virus and Epizootic Hemorrhagic Disease Virus
Bluetongue virus (BTV) and epizootic hemorrhagic disease virus (EHDV) are orbiviruses that infect both livestock and wild ruminants. Antigenic cross-reactivity between BTV and EHDV often results in serologic misdiagnosis. Competitive enzyme-linked immunosorbent assays (c-ELISAs) show increased sensitivity and specificity for the identification of these viral
