Protection Efficacy of Recombinant HVT-ND-LT and the Live Attenuated Tissue Culture Origin Vaccines Against Infectious Laryngotracheitis Virus When Administered Individually or in Combination.

Infectious laryngotracheitis (ILT) is a respiratory disease that causes significant economic losses to the poultry industry. Control of the disease is achieved by vaccination and implementation of biosecurity measures. The use of bivalent and trivalent recombinant herpesvirus of turkey (rHVT) vaccines expressing infectious laryngotracheitis virus (ILTV) genes has increased worldwide.

Comparative genomic analysis of genomes associated with spotty liver disease, Georgia, United States.

has re-emerged as an important cause of disease in egg laying birds worldwide, resulting in morbidity, mortality, and significant losses in eggs for the breeding and table egg laying industries. Although birds may appear asymptomatic, the disease is characterized by spots on the liver of birds and histopathological analysis reveals multifocal fibrogranulocytic necrotizing hepatitis microscopically. The re-emergence of may be linked with housing practices as the disease appears more prevalent in pasture raised birds with outside exposure.

in the Production Environment and Stagnant Water as a Potential Source of Causing Spotty Liver Disease in Free-Range Laying Hens in Georgia, United States.

Spotty liver disease (SLD) has emerged as an important cause of disease in egg-producing flocks in countries such as the United Kingdom and Australia and has emerged in the United States. The organisms implicated in SLD include and, more recently, . These organisms have been found to cause focal lesions on the livers of infected birds.

Complete Genome Sequence of Campylobacter hepaticus RBCL71delta, Associated with Spotty Liver Disease in Organic Pasture-Raised Laying Hens in Georgia, USA.

Spotty liver disease (SLD) is as an important cause of disease in egg-producing flocks. The organisms implicated include Campylobacter hepaticus and Campylobacter bilis. Here, we report the complete genome sequence of strain RBCL71delta and three additional strains, isolated from a layer flock in Georgia, USA.
