Abstract
Now-a-days, the poultry production in Bangladesh has become a sustainable and profitable industry. The poultry sectors are contributing to meet the national demand of proteins as well as implementing food security along with employment generation. The poultry industries are frequently affected by respiratory diseases. There are five viral respiratory diseases associated with respiratory systems such as Avian influenza (AI), Newcastle disease (ND), Infectious bronchitis (IB), Infectious laryngotracheitis (ILT), and Avian metapneumovirus (AE). Among them, AI outbreaks have been occurring regularly with changing genetic characters since 2007 and atotal of 556 AI outbreaks have been reported yet in Bangladesh that placed in most AI reporter countries. Bacterial diseases like Mycoplasmosis, Ornithobacterium rhinotracheale, Fowl cholera, and Infectious coryza are mostly prevalent respiratory diseases in Bangladesh. Mycoplasmosis is become a major threat for poultry industry especially Sonali (a cross-bred) type chickens due to poor biosecurity and breeding management. With respect to fungal diseases, Aspergillosis or brooder pneumonia is a highly prevalent respiratory disease in Bangladesh with causing pneumonia in young chickens. However, respiratory diseases are prevalent in higher rates and cause outbreaks frequently.

The avian respiratory system begins with nostril and ends with lungs and air sacs
Viral diseases like Avian influenza (AI), Newcastle disease (ND), Infectious bronchitis (IB), Infectious laryngotracheitis (ILT)and Avian metapneumovirus; bacterial diseases like Mycoplasmosis, Ornithobacterium rhinotracheale, Fowl cholera and Infectious coryza; and fungal disease like Aspergillosis are responsible for causing respiratory diseases
Infectious bronchitis is the most economic disease in poultry all over the world including Bangladesh caused by the Infectious bronchitis virus (IBV)
Summary
The avian respiratory system begins with nostril and ends with lungs and air sacs. It is divided into the upper and lower respiratory system (Tully, 1995). The most serious and paramount important economic diseases of poultry are respiratory diseases (Roussan et al, 2008). Every pathogen has unique trends regarding their infection pattern, transmission, clinical symptoms, control strategy and vaccination (Ali, 2018). Often, they show similar clinical signs and become difficult to differentiate based on their lesions. The study aimed to describe the prevalence, risk factors and distribution of common respiratory diseases of poultry in Bangladesh
