25. Synchronization of ovulation in crossbred dairy heifers using gonadotrophin-releasing hormone agonist, prostaglandin F2a and human chorionic gonadotrophin or estradiol benzoate
Girolando (Gir x Holstein) is a very common dairy breed in Brazil because it combines the rusticity of Gir (Bos indicus) with the high milk yield of Holstein (Bos taurus). The ovarian follicular dynamics and hormonal treatments for synchronization of ovulation and timed artificial insemination were studied in Girolando heifers. The injection of a gonadotroph

This work had as score toevaluate the losses in milk due to the subclinical mastitis (SCM) troughthe Kirk s (1984) linear score. The sensivity of the direct evaluation of the somatic cells in the milk was also studied as an indirect diagnostic of the SCM in cattle. Four cattle herds of EPAMIG (Empresa Pesquisa Agropecuária de Minas Gerais) were worked out T

27. Conservation of Babesia bovis Small Heat Shock Protein (Hsp20) among Strains and Definition of T Helper Cell Epitopes Recognized by Cattle with Diverse Major Histocompatibility Complex Class II Haplotypes
Babesia bovis small heat shock protein (Hsp20) is recognized by CD4+ T lymphocytes from cattle that have recovered from infection and are immune to challenge. This candidate vaccine antigen is related to a protective antigen of Toxoplasma gondii, Hsp30/bag1, and both are members of the α-crystallin family of proteins that can serve as molecular chaperones.

28. Induction of CD18-Mediated Passage of Neutrophils by Pasteurella haemolytica in Pulmonary Bronchi and Bronchioles
Pasteurella haemolytica is an important respiratory pathogen of cattle that incites extensive infiltrates of neutrophils into the lung. In addition to the parenchymal damage caused by factors released by P. haemolytica, neutrophils contribute to the pathologic changes in the lungs. Molecules which mediate neutrophil infiltration into the lungs during P. haem
