Abstract

The authors of the article consider an avian disease -the respiratory mycoplasmosis of birds, its etiology, pathogenesis, description of clinical and pathoanatomical and pathohistological features of the course of the disease. In our country, despite the fact that there is a developed system against respiratory mycoplasmosis of birds, based on protection of farms from the introduction of infection from the outside, compliance with veterinary and sanitary rules, zoohygienic and technological standards, as well as measures aimed at timely detection of the disease, the problem of the spread of this disease is quite acute. Currently, the topic of respiratory mycoplasmosis does not lose its relevance precisely because of the high percentage of infection in poultry farms. For example, as a result of research conducted by the ARRIAH over the past 5 years, it was revealed that 218 out of 250 poultry farms in Russia were diagnosed with respiratory mycoplasmosis.

Highlights

Avian respiratory mycoplasmosis (Latin: Mycoplasmosisrespiratoria) is a chronic contagious infectious disease, the causative agent of which is Mycoplasma gallisepticum, characterized by respiratory damage, exhaustion and reduced productivity [3, 5, 7, 11, 12, 17].The causative agent of avian respiratory mycoplamosis is Mycoplasma gallisepticum
The causative agent belongs to Mycoplasmataceae family, Mycoplasma genus, Mycoplasma gallisepticum species
The main sign of respiratory mycoplasmosis is a disorder of the function of respiratory organs

Summary

Introduction

Avian respiratory mycoplasmosis (Latin: Mycoplasmosisrespiratoria) is a chronic contagious infectious disease, the causative agent of which is Mycoplasma gallisepticum, characterized by respiratory damage, exhaustion and reduced productivity [3, 5, 7, 11, 12, 17]. Mycoplasma gallisepticum enters the upper respiratory tract, but may not cause disease for a long time. The main sign of respiratory mycoplasmosis is a disorder of the function of respiratory organs There are symptoms such as shortness of breath, cough, tracheal wheezing, a bird breathes with its beak open. Mortality is most often associated with the pathogenic effect of another bacterial or viral infection that has joined, for example, E. coli, viral infectious bronchitis, laryngotracheitis This is the danger of respiratory mycoplasmosis. Ducklings lag behind in growth and development, during clinical examination we may note mucosal and mucosal-serous rhinitis, swelling of supraorbital sinuses, conjunctivitis Geese with this disease have a decrease in egg production during last 2 months of egg laying. Sick goslings have shortness of breath, rhinitis, lameness and lag in growth and development [4]
