According to the novel grading system, high-grade MCTs were significantly associated with shorter time to metastasis or new tumor development, and with shorter survival time.

Both IHC and AgELISA are accurate at detecting BVDV-infected calves, but veterinarians and producers should be advised that both tests detect some calves acutely infected with BVDv in addition to PI animals.

Although all colostrum and milk samples from infected ewes were strongly PCR positive, the appearance of detectable SA-MCFV DNA in lambs was correlated generally with antibody patterns, which suggests that the natural infection event in sheep may not occur during the perinatal period but occurs sometime later in life.
Chronic and recovered cases of sheep-associated malignant catarrhal fever in cattle

Observations indicate that recovery and chronic disease are a significant part of the clinical spectrum of MCF and that such cases occur with some frequency in the area studied.

This review focuses on recent efforts to understand the pathogenesis of MCF, particularly the sheep-associated form of the disease, with the goal of developing rational control methods, including vaccination.
Malignant Catarrhal Fever in a Bison (Bison Bison) Feedlot, 1993–2000

A fatal enteric syndrome was identified in American bison (Bison bison) at a large feedlot in the American Midwest in early 1998, and a prospective study was undertaken to establish the importance of MCF relative to other fatal diseases at the feedlot.
Transmission of Ovine Herpesvirus 2 in Lambs

The study showed that OHV-2 infection does not commonly occur in perinatal lambs and that OHv-2-free sheep can be established by separation of lambs at the proper time, which has important implications for potential control measures.
Experimental aerosol infection of cattle (Bos taurus) with ovine herpesvirus 2 using nasal secretions from infected sheep.

Questions of technique, analysis, and evaluation should be put through formal scrutiny in rigorous clinical studies in the near future so that more definitive guidelines can be derived.
