An Infectious Ophthalmia of Cattle

Infectious Ophthalmia of Cattle

Cows from a midwestern state suffering with acute ophthalmia had been introduced into the herd early in September, 1922. A considerable number of cases occurred in cows in two adjoining barns during September and October. With the onset of cold weather the epidemic subsided but sporadic cases occurred during the colder months. The disease again became epidemic during the months of July, August,...

Detection of antibody against infectious bovine rhinotracheitis glycoprotein gE in aborted cattle in Mashhad, Iran

Infectious Bovine Rhinotracheitis is a highly contagious disease caused by the bovine herpes virus-1 (BoHV-1), resulting in significant losses to livestock around the world. BoHV-1 is a major pathogen of cattle, primarily associated with respiratory/genital tract infections and abortion. In the present study, we determined the presence of antibodies in 120 serum samples of cattle with the histo...

Elemental analysis of melanins from bovine hair, iris, choroid, and retinal pigment epithelium.

According to recent theory on the structure of melanin, the sulfur content of melanin is a reflection of the amount of cysteine used in its manufacture. We compared the sulfur contents of melanins from hair, choroid, iris, and retinal pigment epithelium from black-haired cattle and separately from red-haired cattle. In black-haired cattle, sulfur contents of hair and ocular melanins were all be...

A mathematical model for treatment of bovine brucellosis in cattle population

Brucellosis is an infectious bacterial zoonosis of public health and economic significance. In this paper, a mathematical model describing the propagation of bovine brucellosis within cattle population is formulated. Model analysis is carried out to obtain and establish the stability of the equilibrium points. A threshold parameter referred to as the basic reproduction number $mathcal{R}_{0}$ i...
