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. Species tested for susceptibility to cerumen were Staphylococcus aureus, Staphylococcus epidermidis. Streptococcus pyogenes, Propionibacterium acnes, Corynebacterium spp, Escherichia coli, and Serratia marcescens. The reduction depended upon the species of bacterium and the age of the culture. Pathogenic species appeared to be more susceptible… 

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.

The activity against yeasts of human cerumen

This study examines the activity of normal human cerumen against two common Candida spp.

Study of common aerobic flora of human cerumen

The organisms isolated as common bacterial components of human cerumen in the experience were similar to those found by other authors, however, the mean count was much higher and could be related to climatic conditions and to the length of time the cerumen had remained in the external auditory canal.

Antibacterial and antifungal properties of human cerumen.

Cerumen was demonstrated to have potential antimicrobial effects on strains of Staphylococcus aureus, Pseudomonas aeruginosa and Candida albicans.

A study of antibacterial and antifungal A study of antibacterial and antifungal properties of human cerumen properties of human cerumen

Human cerumen has antibacterial and antifungal properties against the commonest bacterial and fungal pathogens and routine wax removal/ear cleaning is not mandatory unless impacted wax is leading to earache or conductive hearing loss.

Lipolytic, Proteolytic, and Cholesterol-Degrading Bacteria from the Human Cerumen

The isolation of multiple bacterial species from human cerumen is described showing that many of these bacteria harbor biochemical traits enabling them to utilize different cerumen components for their growth.

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.

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.

Studies of the microenvironment and microflora of the canine external ear canal

Marked variation was found in the distribution of sebaceous and apocrine glands in the aural integument in healthy ears and those with otitis, and the numbers of microorganisms found in cerumen cytological smears appear to be correlated to the growth density of microbial colonies on culture plates.



Bactericidal activity of cerumen.

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

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

Micro-Chemical Studies on Normal Cerumen

The study herein reported was undertaken to measure any difference between the composition of casualf cerumen that has remained in the ear for a period of weeks or months may not be the same as that of fresh cerumen.

Management of the ear canal seborrhea with cerumen

For the past 20 years, the author has been treating recurrent chronic seborrheic dermatitis with a suspension of human cerumen in glycerine. The cerumen is obtained from healthy children and young

Ether-soluble substances on the skin of the human external auditory canal.

A study of the ether-soluble substances found on the skin surface of the auditory canal found micromethods were developed and applied for measuring the samples of secretion.
