Therefore, for accurate antibiotic susceptibility profiles, both aerobic and anaerobic bacteria
should have been taken into account and separate culture media should have been used for their isolation.
were detected in 5 (14%), monomicrobial infection in 34 (94%), and polymicrobial infection in 2 (6%) patients.
Development of antibiotic resistance among anaerobic bacteria
has tremendous impact on the selection of antimicrobial agents for empirical therapy.

In this study we found wide range of gram positive, gram negative, aerobic and anaerobic bacteria
as shown in table (3) the most bacteria we found was the aerobic bacteria (10 strains) including Bacillus sp.
Dr Harold Katz, a dentist specialising in bacteriology, says: "Almost all bad breath odours are caused by anaerobic bacteria
living in the back of the tongue, throat and tonsils, which break down the proteins in our food as part of their daily job.
Bad breath occurs when excess anaerobic bacteria
, which lurk in places that oxygen cannot easily reach, release foul-smelling gases.
can also lead to painful and potentially serious conditions such as gingivitis and periodontitis, so it's best to attack the problem at the root.
The Bacteroides fragilis group consists of species of obligate anaerobic bacteria
that inhabit the human gut.
After one year, however, the prevalence and amount of 12 types of anaerobic bacteria
were lower among circumcised men than among uncircumcised men.
Levels of 12 kinds of anaerobic bacteria
, which need an environment devoid of oxygen, had decreased.

(anaerobes) are the predominant flora on human skin and mucous membranes and are a common cause of endogenous infections.
