Abstract Cerumen is the product of the secretion of the sebaceous, ceruminous or apocrine glands together with cells exfoliated from the cornified stratum of the epithelium of the external auditory canal (EAC). In the present study we identified and quantified common flora of human cerumen. The mean count obtained was 106 microorganisms per ml of cerumen suspension. In 24 pools of cerumen (33.3 per cent) the isolates were monomicrobial, Staphylococcus epidermidis (12), Corynebacterium spp (10… 

Microbiology of Cerumen Bacterial Flora of Acute Otitis Externa Patients

Isolated bacteria from cerumen of healthy subjects were different in comparison to those of acute otitis externa patients, and there was significant association between colony count and actue otitisExterna status.

Microbiologic Study of the Ear Canal in Koreans

Coagulase-negative staphylococcus (CNS) were found to be the predominant microorganism and, in particular, Staphylitis capitis was the most commonly isolatedmicroorganism from the normal external auditory canal in Koreans.

Microbiology of itchy ears

There need not be an underlying bacterial or fungal infection to cause itching as evidenced by a con-dition called asteatosis, which should be considered as one of the differential diagnosis for chronic and persistent itching when all other causes have been ruled out.

Comparing Cerumen Bacterial Flora in Acute Otitis Externa Patients and Healthy Controls

The effect of Mazandaran province's humid weather on the prevalence of pathogenic microorganisms and the bacterial flora of the ear in patients with acute otitis externa and its comparison with healthy subjects was determined.

Influence of human wet cerumen on the growth of common and pathogenic bacteria of the ear

In vitro, the most observable effect was in fact an increase in microbial growth, which does not support the conception of a decrease in bacterial growth produced by humen wet cerumen.

Microbiology of cerumen in patients with recurrent otitis externa and cases with open mastoidectomy cavities

In the process of investigating the microbial flora of cerumen in all the three groups, microbial growth was observed from all the samples from patients with an open cavity, unlike the other groups, and it was determined that the group with recurrent external otitis had the most abundant microbial flora.

Antimicrobial Effect of Ear Wax (Cerumen auris)on Some Animal Pathogens

The results have demonstrated that the antimicrobial impact of ear wax suspension revealed exceptionally huge against Bacillus followed by Salmonella and Klebsiella with similarly impact while there is no antimicrobial effect of the suspension on both Staph and Pseudomonas.

Antimicrobial resistance of Staphylococcus from otorrhea in chronic suppurative otitis media and comparison with results of all isolated Staphylococci

MRSA was the most frequently identified Staphylococcus in patients with otorrhea and annual isolation rates showed no tendencies to increase or decrease, and continuous and periodic surveillance of MRSA is necessary to reduce the spread of antibiotic-resistant pathogens and to guide appropriate antibacterial therapy.

Antimicrobial properties of human cerumen

Cerumen cleaning is not advisable unless it is causing symptoms such as otalgia or hearing loss, so a large percentage of people believe in self-cleaning of the ear canal with different objects, which is really harmful, so they should be counseled against the habit of self- cleaning of the external auditory canal.



Etiology and therapy of chronic suppurative otitis.

P. aeruginosa was the most commonly isolated and showed the highest percentages of resistance against antimicrobial agents tested, and S. aureus was highly sensitive to amoxicillin/clavulanate, trimethoprim-sulfamethoxazole, rifampin and teichoplanin.

Microbiological studies of the bacterial flora of the external auditory canal in children.

These findings demonstrate the polymicrobial bacterial flora of EAC in children where aerobic facultative and anaerobic bacteria are part of the normal flora.

Cerumen and its Micro-Chemical Analysis

It has been observed that cerumen is more frequent and voluminous in males than in females, and in adults than in children; its amount may vary, however, from one ear to another according to the relative vitality of the ceruminous glands.

Bactericidal Activity of Wet Cerumen

The viable populations of seven species of bacteria were reduced 17% to 99% by treatment with a 3% suspension of human cerumen of the soft or “wet” type and the bactericidal activity of wet cerumen was found to be quite similar to that of dry cerumen.

Aerobic and anaerobic microbiology of external otitis.

The polymicrobial nature of external otitis in one third of the patients and the role of anaerobic bacteria in one-quarter of them are illustrated to illustrate the poly microorganisms in this infection.

Bactericidal activity of cerumen

The results support the hypothesis that cerumen functions to kill certain foreign organisms which enter the ear canal.

Clinical and microbiological features of otitis externa.

It was found that previous usage of ear drops was more often associated with otomycosis in acute otitis externa and yet was not related to a higher frequency of otomyCosis in chronic otitisExterna.

Studies on the growth of bacteria in the human ear canal.

The relationship between bacteria and external otitis in man is vague and even though microorganisms can be cultured from the external auditory canal, they are found to be completely unrelated to the disease process.

[Bacteriologic findings in ear exudates from ambulatory care patients].

The results obtained in a microbiological survey carried out with 102 samples of otic effusions taken from 95 outdoor patients in a ORL surgery are shown. Sixty-eight of these patients had supurative

Otomycosis—A continuing problem

The incidence and pattern of fungi and the accompanying bacteria, in case of mixed infection, do not appear to have been affected by the widespread use of powerful topically-applied autibiotic/steroid preparations over more than two decades.
