Bovine respiratory disease (BRD) is the most common and economically devastating infectious disease affecting beef cattle in the world. [1] It is a complex, bacterial or viral infection that causes pneumonia in calves which can be fatal.
[3] [6] Cattle are believed to have been infected from being fed meat and bone meal that contained the remains of other cattle who spontaneously developed the disease or scrapie-infected sheep products. [3] The outbreak increased throughout the United Kingdom due to the practice of feeding meat-and-bone meal to young calves of dairy cows. [3] [8]
Contagious bovine pleuropneumonia (CBPP – also known as lung plague), is a contagious bacterial disease that afflicts the lungs of cattle, buffalo, zebu, and yaks. It is caused by the bacterium Mycoplasma mycoides, and the symptoms are pneumonia and inflammation of the lung membranes. [1] The incubation period is 20 to 123 days.
Parasitic bronchitis, also known as hoose, husk, or verminous bronchitis, [1] is a disease of sheep, cattle, goats, [2] and swine caused by the presence of various species of parasite, commonly known as lungworms, [3] in the bronchial tubes or in the lungs. It is marked by cough, dyspnea, anorexia and constipation.
This disease affects the upper respiratory tract as well as the reproductive tract of cattle, and is commonly found in feedlots across North America. [2] Clinical symptoms include fever, serous to mucopurulent nasal discharge, coughing, sneezing, difficulty breathing, conjunctivitis and loss of appetite. Ulcers commonly occur in the mouth and nose.
Fog fever is a refeeding syndrome in cattle, clinically named acute bovine pulmonary emphysema and edema (ABPEE) and bovine atypical interstitial pneumonia. [1] [2] This veterinary disease in adult cattle follows an abrupt move from feedlot (dried feed indoors) to 'foggage pasture' (fast growing, lush pasture, with high protein levels).
Eye Ring. Bovine malignant catarrhal fever (BMCF) is a fatal lymphoproliferative disease [1] caused by a group of ruminant gamma herpes viruses including Alcelaphine gammaherpesvirus 1 (AlHV-1) [2] and Ovine gammaherpesvirus 2 (OvHV-2) [1] [3] These viruses cause unapparent infection in their reservoir hosts (sheep with OvHV-2 and wildebeest with AlHV-1), but are usually fatal in cattle and ...
A more acute form of East Coast fever called corridor disease occurs when buffalo-derived T. parva is transmitted to cattle. [3] Another form, called January disease, only occurs over the winter months in Zimbabwe due to the tick lifecycle. [citation needed] Native cattle are often resistant to the parasite, but not without symptoms. They are ...
