Background: The rate of infection with Clostridium difficile colitis and its associated mortality have been increasing in the last decade. The molecular epidemiology of C. difficile in Israel has as yet not been studied.

Objectives: To screen for the existence of the 027 and 078 ribotypes and determine the longitudinal molecular epidemiology of the circulating clinical C. difficile isolates in a large hospital in central Israel.

Methods: Polymerase chain reaction (PCR) ribotyping was performed on C. difficile isolates obtained from hospitalized patients from November 2003 to May 2004 (first study period) and September 2009 (second study period). Isolates with PCR[1] ribotype patterns, unlike those of the available reference strains (078 and 027), were labeled with letters. Forty-six isolates from the first study period and 20 from the second were analyzed.

Results: PCR strain typing of C. difficile isolates yielded approximately 26 unique ribotypes. During the first study period, ribotype A and B accounted for 30% and 28%, respectively, whereas ribotype E and K accounted for 6.5% for each. During the second study period, ribotypes A, E and K disappeared, and the incidence of ribotype B decreased from 28% to 15%. One isolate (1/20, 5%) emerged during the second period and was identified as ribotype 027. Moxifloxacin resistance was found in 93% of ribotype A isolates, 81% of the ribotype B group, and in 44% of other ribotypes.

Conclusions: The predominant ribotypes circulating in our institution were diverse and changing. This is the first report on the emergence of the 027 ribotype in Israel.

 Background: Perichondritis of the auricle is a serious disease that may lead to residual deformity. 

Objectives: To assess our experience with perichondritis in a large group of patients hospitalized with this entity.

Methods: We retrospectively studied 114 patients who were admitted with perichondritis during 1987–2004, including their demographic details, medical history, current illness, etiology, pathogens and treatments. 

Results: The patients’ mean age was 41.8 ± 20.7 years. In more than half of the patients the etiology could not be determined. Forty-seven patients (41%) were treated prior to hospitalization for an average of 2.5 ± 1.9 days. Eight patients (7%) required surgical intervention. Pseudomonas aeruginosa was found to be the predominant organism (69% of available isolates) and was associated with a more advanced clinical presentation and longer hospitalization (P = 0.008). 

Conclusions:  Perichondritis develops in many cases after apparent minor trauma. Since P. aeruginosa is probably the predominant pathogen, initial treatment should include anti-pseudomonal antibiotics.
