“…Only 1 P. aeruginosa isolate from mPA-C and 4 isolates from mPA-B were apyocyanogenic. All isolates from both mPA media which fluoresced were confirmed as P. aeruginosa; no unidentified fluorescent pseudomonads (10,11) were isolated.…”

A modified mPA medium, designated mPA-C, was shown to recover Pseudomonas aeruginosa from a variety of water sources with results comparable to those with mPA-B and within the confidence limits of a most-probable-number technique. Enumeration of P. aeruginosa on mPA-C was possible after only 24 h of incubation at 41.5°C, compared with 72 h of incubation required for mPA-B and 96 h of incubation for a presumptive most probable number.

“… 15–16 In immunocompetent individuals, the mean duration of untreated PF is 15 days, although in some cases PF may persist for many weeks. 1 The most frequent serotypes reported are 0 : 11 1–15 and, to a lesser extent, 0 : 4. 2 …”

“… 2 Water temperature, pH, and chlorine content are factors influencing skin infection by Pseudomonas aeruginosa as this microorganism is capable of surviving in alkaline, warm water, 9–10 and the effect of chlorine in such physicochemical conditions is decreased. 11–12 The correct free chlorine concentration to prevent Pseudomonas growth is 0.4–0.5 mg/L. 12–13 …”

Pseudomonas aeruginosa folliculitis after shower/bath exposure

Based on our experience, we suggest that shower/bath exposure should be definitively included amongst the possible pathogenic events causing PF. Pseudomonas aeruginosa is responsible for a number of clinical pictures, e.g. otitis externa, conjunctivitis, toe web intertrigo, green nail syndrome, infection of burns and wounds, and folliculitis. Pseudomonas aeruginosa folliculitis (PF) has been reported to develop as a consequence of exposure to contaminated water in heated swimming pools, whirlpools, and hot-tubes, or related to diving suits and leg waxing.1-4 We observed 14 cases of PF after shower/bath exposure. This is probably an underestimated pathogenic event; to our knowledge, only one case has been reported to date.5 In our patients, the clinical expression of dermatitis was constant, PF being a clinically well recognizable skin condition.

“…In particullar the recent outbreaks of skin infection which have occulrred in the United States as a result of the increasing popularity of heated whirlpool baths have highlighted the potential hazards of Pseudomonas aeruginosa in bath waters (AMeCausland & Cox, 1975;Jacobson, Hoadley & Farmer, 1976;Washburn, Jacobson & Narstib, 1976;Sausker et al 1978). P. aeruginosa can be isolated fronm swimming pool waters, particularly if there is a high bather load, inadequate chlorination or increased water temperatuire (Brodsky & Nixon, 1974;Hoadley, Ajello & Masterson, 1975;Schinidler, Metz & Hellwig, 1978;Kuish & Hoadley, 1980). Under certaiin conditions suich strains can become resistant to chlorine treatment (Black et al 1970;Seyfried & Fraser, 1980).…”

Pseudomonas aeruginosa was isolated from the ears of 18 of the 25 members of a team of competitive swimmers who complained of painful discharging ears. This group of swimmers trained twice daily in the pool, in the early morning and late afternoon. In contrast swabbing of the ears of a similar group of 54 competitive swimmers who used the pool only in the afternoon revealed only one swimmer with P. aeruginosa. Investigation of the swimming pool revealed that chlorination was often inadequate when the first group of swimmers were training in the early morning. Strains of P. aeruginosa were isolated from various sites around the pool and from the bag of a vacuum used to clean the pool. Pyocin typing, serotyping and phage typing were performed on all isolates. The dominant strain recovered from the swimmers' ears was found to be almost identical to that from the vacuum bag and belonged to serotype 0--11 which has been particularly associated with outbreaks of P. aeruginosa infection in whirlpools in the United States. These results support the hypothesis that there is a direct correlation between the development of otitis externa and swimming in water contaminated with P. aeruginosa.
