Respiratory Microbiome

Elucidating the complex microbial interactions in biological environments requires the identification and characterization of not only the bacterial component but also the eukaryotic viruses, bacteriophage, and fungi. In a proof of concept experiment, next generation sequencing approaches, accompanied by the development of novel computational and bioinformatics tools, were utilized to examine the evolution of the microbial ecology of the avian trachea during the growth of a healthy commercial broiler flock. The flock was sampled weekly, beginning at placement and concluding at 49 days, the day before processing. Metagenomic sequencing of DNA and RNA was utilized to examine the bacteria, virus, bacteriophage, and fungal components during flock growth. The utility of using a metagenomic approach to study the avian respiratory virome was confirmed by detecting the dysbiosis in the avian respiratory virome of broiler chickens diagnosed with infection with infectious laryngotracheitis virus. This study provides the first comprehensive analysis of the ecology of the avian respiratory microbiome and demonstrates the feasibility for the use of this approach in future investigations of avian respiratory diseases.

Laryngotracheitis Virus

Infectious laryngotracheitis (ILT) is a viral disease of poultry species caused by infectious laryngotracheitis virus (ILTV) that shows high morbidity and mortality. The present study was under taken for ILTV prevalence in broiler and layer chickens from four different geographical areas including Bogura, Gazipur, Chattogram and Dhaka districts during 2017 to 2018. Total 350 tracheal swabs were collected and were evaluated by real time RT-PCR (rRT-PCR). The overall 5.14% (18/350) ILTV prevalence was found that included 6.5% (13/200) in layer and 3.33% (5/150) in broiler chickens. The prevalence of ILTV was highest (10%) in layer chickens under age below 20 weeks and broiler chicks showed ILTV (1. 42%) infection when they were 7-14 days old. Winter season showed highest 6.6% prevalence whereas 5% and 3% prevalence were noticed at summer and rainy seasons, respectively. Bang. J. Livs. Res. Vol. 27 (1&2), 2020: P. 113-117
