Detection of the main bacterial causative agents associated with pneumonia cases of pigeons in al-Diwaniya province

الملخص EN

In this study, infected lung samples of pigeons at Al-Diwaniya province were tested for the presence of some aerobic bacteria.

The identification of bacteria were proved by swabs culturing and biochemical tests.

A total of 100 pigeons were examined at post-mortem, and 100 samples with pneumonia were collected.

All lungs were collected from different local pigeon’s market showing respiratory disorders.

Blood agar supplemented with 7% sheep blood was used for isolation of the agents.

Two methods were used for culturing the samples collecting from lung which include direct and indirect methods.

In both methods bacterial colonies were identified on blood agar and MacConkey agar after that differential media was used for bacterial purification; various biochemical tests were used to study the properties of each bacterium.

The aim of this work was to isolate and identify the aerobic bacteria associated with cases showing typical signs of respiratory infections.Bacteriological result showed (107) bacterial isolates which include Escherchia coli represent high percentage (29.9%) and ,Staphylococcus spp.(14.%) were considered the most predominant bacteria in comparison to other isolated bacteria which include Streptococcus pneumonia, K.

pneumonia, E.

aerogenense and P.

vulgaris.

This study showed that E.

coli is the most prevalent bacterial infection among pigeon population in Al-Diwaniya province.
