Anaerobic bacteria associated with osteomyelitis in domestic animals.

This research article studies the type of anaerobic bacteria that are often found in cases of bone infection (osteomyelitis) in animals, their properties, and the percentage of cases in which such bacteria were found compared to other bacteria species.

Objective of the research

• The primary objective of this research was to identify the type and frequency of anaerobic bacteria (bacteria that can survive and grow in environments with no or very little oxygen) associated with osteomyelitis in domestic animals. The researchers examined bony or soft tissue from 19 animals suffering from this bone disease.

Research methodology

• In this study, samples from diseased animals were cultured under two distinct environments: aerobic (oxygen-rich) and anaerobic (low or no oxygen) to identify and compare the bacteria growing in these conditions.

Findings

• The research demonstrated that in 14 out of 19 specimens (74%), anaerobic bacteria were present, either on their own or coexisting with aerobic or facultative anaerobic bacteria. Facultative anaerobic bacteria are adaptable and can live either with or without oxygen.
• The predominantly found anaerobic genus was Bacteroides, a robust type of bacteria that thrives without oxygen (obligate anaerobe).
• Within the Bacteroides genus, Bacteroides asaccharolyticus was isolated five times, making it the most frequent type of Bacteroides.
• The most commonly isolated anaerobic bacterium overall was Peptostreptococcus anaerobius, isolated six times.
• Regarding aerobic bacteria, which thrive in oxygen-rich environments, the study found Staphylococcus aureus and Escherichia coli to be prevalent. They were isolated seven and six times, respectively.

Significance

• The findings of this study highlight the primary anaerobic bacteria associated with animal bone infection. Understanding the bacterial profile can provide crucial insights in diagnosing and treating osteomyelitis across different animal species.
