1. Detecção do virus da diarréia bovina em carrapatos Rhipicephalus (boophilus) microplus alimentados em bovino persistentemente infectado
Background: Bovine viral diarrhea virus (BVDV) is one of the main agents that cause economical losses in cattle worldwide. Congenitally infected calves that are born persistently infected (PI) to BVDV are the main sources of infection to susceptible cattle. Direct contact is the most important form of transmission, but indirect contact can also spread BVDV,

3. Emprego de estirpes de leptospiras isoladas no Brasil, na microtécnica de soroaglutinação microscópica aplicada ao diagnóstico da leptospirose em rebanhos bovinos de oito estados brasileiros / Use of strains of leptospires isolated in Brazil, for the microscopic agglutination test applied to the diagnosis of leptospirosis in bovine herds of eight Brazilian states
Bovine leptospirosis is one of the main reproductive diseases which interferes economically on the livestock and thus it is needed the amelioration of the laboratory diagnostic procedures. The aim of this work is to investigate the adequacy to use autochthonous strains of leptospires isolated in Brazil, added into the antigen collection applied for the micro

4. Origin and distribution of the axillary nerves in zebu-crossed bovine fetuses / Origem e distribuição dos nervos axilares em fetos de bovinos azebuados
In this study, the origin and distribution of the axillary nerve in 30 fetuses of zebu-crossed bovines, 20 males and 10 females, were analyzed through dissection after fixation in an aqueous solution of 10% formaldehyde. The axillary nerve was found to originate in 13.33% of the antimeres of the ventral branch of the 6th cervical (C6) spinal nerve, in 100% o

5. AvaliaÃÃo de aberraÃÃes cromossÃmicas em bovinos (Bos taurus taurus) infectados pelo papilomavÃrus bovino
Bovine papillomavirus (BPV) is represented by 10 papillomavirus subtypes, epiteliotropic or mucosotropic, which are transmitted among bovines through contaminated blood and ephitelial contact. This virus may be in a latent form on host lymphocytes, triggering chromosomal instabilities. In this context, this study aimed to evaluate chromosomal aberrations whi

6. Behavior characteristics of Rhea americana in captivity submitted to different photoperiods and relations male:female / Características comportamentais de emas em cativeiro submetidas a diferentes fotoperíodos e relações macho:fêmea
Researches has revealed that animal welfare is determinant on economic and technical viability of animal production systems. In this way the understanding of animal behavior will be a useful tool for detection of problems that interferes in the animal confort and promove damages to the producer. The animals behave according determined standards. Those standa

10. Antiluteolytic activity in the uterine microenvironment during the critic period to pregnancy establishment in bovines / Atividade antiluteolítica no microambiente uterino durante o período crítico para o estabelecimento da gestação em bovinos
The inhibition of pulsatile secretion of PGF2α mediated by interferon-tau (IFN) is fundamental on the maternal recognition of pregnancy, maintaining the progesterone secretion by corpus luteum. Therefore the measurement of interferon activity in the uterine microenvironment was studied. Due to a lack of assays those measure specific antiluteolytic capa
