Objectives:
We evaluated the correlation between the microbial content of chronic suppurative otitis media (CSOM) and regional climatic parameters.
Methods:
We assessed the interrelations between monthly mean records of temperature, maximum temperature, atmospheric pressure, and humidity and the aerobic microbial flora in CSOM.
Results:
Forty-three bacteria of Enterobacteriaceae, 67 staphylococcal spp, 51 Pseudomonas aeruginosa, 9 Streptococcus pneumoniae, 1 alpha-hemolytic Streptococcus, 1 Enterococcus sp, and 2 Edwardsiella tarda strains were recovered from 173 patients with CSOM. There was a good relationship between enteric bacteria and monthly mean temperature (r = 0.501) and significant colonization rates due to increasing monthly mean temperature (p = .040) and monthly mean maximum temperature values (p = .048).
Conclusions:
When the weather warmed, the frequency of isolation of enteric bacteria increased significantly. Temperature changes may affect the enteric bacterial colonization of CSOM.

Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...
