Cattle-to-cattle transmission of Mycobacterium bovis
Tuberculosis, 2001This review, illustrated with data on the characteristics of herds infected with Mycobacterium bovis (TB) in Great Britain (GB), attempts to identify the role of cattle-to-cattle transmission (CCT) of TB. CCT plays a part in the entry of infection into herds, through purchased infected animals or contiguous spread, although CCT can have a relatively ...

Just as the knowledge gleaned from the human genome-sequencing project has made an enormous contribution to human medicine, genomic tools developed as a result of sequencing the bovine genome and a novel methodology to use this information, called genomic selection, are becoming standard practice for dairy cattle selection in the developed world.

Osteochondrosis is a poorly understood condition that affects many species, including cattle. Its incidence is not fully appreciated in the cattle industry for many reasons. Most of the reports show a male, purebred predilection, but this may simply be a result of the typical population for which medical attention is sought.

SUMMARY Some factors influencing the causation of stillbirths in cattle were studied in 105,122 progeny of 100 bulls of eight breeds over a period of 8 years. The breed of dam was not considered. The calves of Friesian bulls were studied in greater detail than those of seven other breeds, in view of the greater numbers available.

Paratuberculosis remains one of the most important diseases of cattle worldwide. In cattle, the disease is debilitating and is characterized by weight loss and chronic diarrhea in the later stages of infection. However, cattle in the subclinical stages of the disease often show decreased milk production and are at higher risk for development of other ...

SUMMARY Blood biochemical studies were performed on 21 azotemic cattle with various disease conditions. The cattle were ≽ 4 months old. Blood urea nitrogen concentrations ranged from 41 to 346 mg/dl. The azotemia was determined to be of prerenal origin in 10 cattle and of renal or postrenal origin in 11 cattle.

Neospora caninum is a coccidian parasite of animals. It is a major cause of abortion in cattle in many countries. Domestic dogs and coyotes are the only known definitive hosts for N caninum. It is one of the most efficiently transmitted infections of cattle, and up to 90% of cattle in some herds are infected.

Abstract Extract The clinical condition of “Kopziekte” or “grass tetany” in cows was recognized in the Netherlands for many years before Sjollema (1928, 1932) and his colleague (Sjollema and Seekles, 1929) first reported its association with low serum magnesium values in distinction to the low calcium of “milk fever”.

SUMMARY Cataracts were detected in 16 cattle of different breeds. On the basis of etiopathogenesis, bovine cataracts were classified into 4 groups: cataracts of congenital origin, cataracts of inflammatory origin, cataracts associated with ocular anomalies, and cataracts of undetermined cause.
