Article Synopsis
- - Infectious Bronchitis Virus (IBV) poses a significant economic threat to the poultry industry globally, with this study focusing on identifying new strains in Bolivia, which were previously uncharacterized.
- - Using real-time RT-PCR, researchers analyzed 12 tissue samples from infected broilers, finding 10 positive for IBV, though only four had enough genetic material for sequencing to assess their lineage.
- - The results identified two lineages (GI-1 and GI-23) of IBV, with GI-1 closely related to vaccine strains, while GI-23 showed distinct genetic differences; mutations in key regions could compromise vaccine efficacy, underlining the need for ongoing monitoring and improved vaccination strategies.
Genome sequencing of highly virulent subsp. enterica serovar Javiana strain FARPER-220 (ST-1674) isolated from broiler chickens in Peru revealed multiple virulence factors, antibiotic resistance genes, and invasion-related subcategories. The results provide insights into the potential importance of this strain in causing infections in various animals.

However, the emergence of new variants of the virus lead to the generation of new alternatives to improve the current sub-unit vaccines in development. In the present report, the immunogenicity of the Spike RBD of SARS-CoV-2 formulated with an oil-in-water emulsion and a water-in-oil emulsion with squalene was evaluated in mice and hamsters.

While mitigation and control strategies provide short term solutions, vaccines play critical roles in long term control of the disease. Recent emergence of potentially vaccine-resistant and novel variants necessitated testing and deployment of novel technologies that are safe, effective, stable, easy to administer, and inexpensive to produce.

- Infectious coryza (IC), caused by Avibacterium paragallinarum, affects growing chickens and layers, necessitating rapid detection tools to prevent economic losses in poultry.* -
- The developed monoclonal antibody 1G7G8 successfully detects TBDT in Av. paragallinarum cultures via methods like Western blot and ELISA, leading to the creation of a lateral flow test (LFT) with a detection limit of 1 × 10 CFU/mL.* -
- The self-pairing prototype LFT demonstrated high sensitivity and specificity when tested on nasal mucus samples from infected chickens, making it a viable option for quick diagnosis in the field.*
