Isolation of Pasteurellaceae from Bovine Abortions

Isolation and characterization of a bovine herpesvirus 3 From cases of calf pneumonia in Iran

Isolation of Yersinia spp. from bovine feces.

Yersinia spp. were sought in 618 fecal samples from cows. Four strains of Yersinia enterocolitica, serotype O:12,26 (one), O:13,7 (two), and O:18 (one); seven strains of Yersinia kristensenii, serotype O:11,24 (five) and O:12,26 (two); and one strain of Yersinia pseudotuberculosis serotype IIB, were isolated. This is the first time that Y. pseudotuberculosis has been isolated from cows in Japan...

Isolation of Cholesterol Sulfate from Bovine Adrenals

the spectra illustrated in Fig. 1 confirm the identity of the isolated material. The salt was hydrolyzed by dissolving the sample in 20 ml of tetrahydrofuran containing perchloric acid (5). After 3 hours at 50”, the solution was brought to neutrality with concentrated NH*OH and the tetrahydrofuran was evaporated under vacuum at 45”. The residue was then partitioned between water and ether, and ...

Isolation of Bovine Herpesvirus-1 (BoHV-1) From Latently Infected/Carrier Cattle in Ahvaz

Bovine herpesvirus 1 (BoHV-1) is one of the most important infectious viruses of cattle which is considered as the causative agent of several clinical conditions in this species. Hence, we tried to isolate a local strain of the virus from carrier cattle in Ahvaz based on a strategy for reactivation of the latent infection in hosts having antibodies against the virus. Thus, 20 cattle were examin...

Novel Chlamydia-like Organisms as Cause of Bovine Abortions, UK

To the Editor: Despite the worldwide economic impact of, and welfare issues associated with, infectious bovine abortifacients, as well as potential zoonotic threats to human health, accurate diagnosis of the causes of abortion is uncommon (1). This poor diagnosis could be explained in part by the lack of identifi cation of infectious abortifacient agents. Although Chlamydophila abortus is a kno...
