The Relationship Between Bacterial Species Isolated from otitis Media and Bacterial Species Isolated from The Environment of the Infected Patients

Abstract

Otitis media (OM) is a widespread disease of the middle ear cavity associated with bacterial or viral pathogens. The current study included a pathological list and diagnosis of some types of bacteria that cause otitis media from the extended period 1/11/2021 to 30/4/2022. This study included 115 swabs of patients for the medical clinic in AL- Tarmiyah General Hospital and of different ages. Bacterial isolates were diagnosed morphologically and culturally by using biochemical tests, using these bacteria to produce enzymes and being positive and negative for gram stain, tests have also been confirmed using Vitek. The Staphylococcus aureus bacteria were the most common among the bacterial species that cause infection at 28 (30.7%). Whereas Burkholdera cepacia group bacteria represented the lowest percentage that was at 1 (1.1%). As for the environmental samples, isolates were obtained from the water used for the areas affected by otitis media, Staph. aureus and E. coli were the most common at 8 (30.8%), While p.aeruginosa, Salmonella enterica represented the lowest rate at 1(3.8%). As for the soil, E.coli and p.aeruginos were in the first place at 5 (20%), were Proteus vulgaris, Proteus mirabilis represented the lowest at 1(4.0% ).
