BACKGROUND Pseudomonas aeruginosa rarely affects the epithelium in healthy persons except for the external ear canal, raising the possibility that P aeruginosa in otitis externa is a specific variety that displays particular characteristics. DESIGN A cohort study was designed to outline distinct characteristics of P aeruginosa in otitis externa compared with P aeruginosa in other infections. The study period was October 1, 1994, to March 27, 1995. PATIENTS Isolates of P aeruginosa from… Expand
Pseudomonas aeruginosa adherence to external auditory canal epithelium.
The significantly increased ability of P aeruginosa, isolated from external otitis, to adhere to external auditory canal epithelium was combined with a significant production of pathogenic factors. Expand
Microbiological Profile and Antibiotic Sensitivity of 100 Cases of Otitis Externa
Otitis externa is a common condition encountered in the ENT outdoors. For long, it was thought to be of fungal etiology but after World War II, bacterial pathogens were found to be most commonlyExpand
Microbiology of otitis externa in the secondary care in United Kingdom and antimicrobial sensitivity.
Polymixin B, gentamicin or ciprofloxacin topical preparations should be used as first line treatment of otitis externa and resistance to penicillin and amoxicillin is observed. Expand
Antibiotic susceptibilities of bacteria isolated from chronic suppurative otitis media
Low resistance to aminoglycosides and quinolones, which are frequently used in the treatment of chronic suppurative otitis media is detected, which will contribute to successfully treating this disease. Expand
External otitis caused by infection with Pseudomonas aeruginosa or Candida albicans cured by use of a topical group III steroid, without any antibiotics
Conclusions Irrespective of the microbial agent, group III steroid solution cured external otitis efficiently in a rat model. The addition of antibiotic components to steroid solutions for theExpand
ReviewCutaneous manifestations due to Pseudomonas infection
The cutaneous manifestations of PA infection represent a wide spectrum of pathologic entities, ranging from minor skin lesions in healthy patients involving the external auditory canals, nails, and toeweb spaces to formidable skin signs of potentially life-threatening Pseudomonas septicemia in immunocompromised patients.

Declining Susceptibility to Neomycin and Polymyxin B of Pathogens Recovered in Otitis Externa Clinical Trials
The organisms most often causing otitis externa appear to be developing resistance to neomycin and polymyxin B but not to ofloxacin, which could hamper bacterial eradication and clinical efficacy of this drug. Expand
A Study on Otitis Externa in A Rural Based Medical College and Hospital
Objectives : To analyze the demographic and clinical aspects of otitis external. Materials and Methods: Retrospective study over a period of 2 years (January, 2014 to December, 2015 ), 3258 patientsExpand
Malignant external otitis in Spain.
Malignant external otitis is seen mostly among male elderly and diabetic patients in Spain, and the incidence and mortality rate are low in Spain. Expand
A topical steroid without an antibiotic cures external otitis efficiently: a study in an animal model
It is inferred that the group III steroid betamethasone dipropionate alone heals experimentally induced external otitis more rapidly than hydrocortisone with oxytetracycline, with or without polymyxin B. Expand


Otitis externa: clinical comparison of local ciprofloxacin versus local oxytetracycline, polymyxin B, hydrocortisone combination treatment.
Ciprofloxacin appears to be a useful and effective agent in the local therapy of otitis externa and microbiological evaluation showed rapid eradication of all bacterial pathogens in the cipro Floxinacin group with 1 persistence of Candida albicans but eradication in the same ear with marked clinical improvement.

Preise typing helps in the identification of environmental sources as well as indicating whether transmission of strains has ocurred between patients, and reveals whether resistant strains which emerge after antibiotic therapy are variants of the original or are newly acquired strains. Expand
Effect of water on the bacterial flora of swimmers' ears.
A bacteriological study of microbial flora in the ear canal of divers and swimmers revealed a direct correlation between degree of exposure of ears to water and type of bacterial flora resident inExpand
