Bacteriological and serological investigation of Clostridium perfringens in lambs.

Clostridium perfringens is one of the most common and important pathogens in livestock due to its ability to produce a diverse arsenal of toxins. Owing to C. perfringens economic importance, this study aimed to determine the types and toxins of C.

Molecular epidemiology and genetic characterization of Clostridium perfringens infections in lambs.

Clostridium perfringens is gram positive bacterium, wide spread in environment causing various diseases in animals and human. The current study was conducted to indentify the genetic identity of C. perfringens isolates from lambs from Egypt.

Equine herpesvirus type 1 ORF51 encoding UL11 as an essential gene for replication in cultured cells.

Equine herpesvirus type 1 (EHV-1) UL11 is a 74-amino-acid tegument protein encoded by ORF51 of the EHV-1 genome. EHV-1 UL11 was previously reported by other researchers using the RacL22 and RacH strains to be nonessential for viral replication in cultured cells. Here, we constructed UL11 mutant viruses including a UL11 null mutant and three C-terminal truncated mutants, for further characterization of EHV-1 UL11 using bacterial artificial chromosome (BAC) technology based on the neuropathogenic strain Ab4p.
