- This report presents the prevalence of Palestinian isolates of methicillin-resistant Staphylococcus aureus (MRSA) in nosocomial infections and their antibiotic resistant pattern. A total of 321 clinical isolates of S. aureus were identified from different patients. The prevalence of methicillin resistance among S. aureus isolates was 8.7% (28 isolates). Resistance rates of MRSA to other antibiotics were as follows: 82.1% resistant to erythromycin, 67.9% to clindamycin, 64.3% to gentamicin, and 32.1% to ciprofloxacin. No co-trimoxazole- and vancomycin-resistant isolates were identified in this study. The proportion of methicillin resistance was highest among S. aureus isolates associated with upper respiratory specimens (42.8%); the proportion of methicillin resistance was 39.3% among skin ulcer isolates, 10.7% among urinary tract infection isolates, and lowest among isolates associated with blood and prostate discharge (3.6% each).

- Thirty-five methicillin-resistant Staphylococcus aureus (MRSA) clinical isolates were collected from 3 hospitals in the northern and southern parts of Palestine between February and May 1998. These isolates were typed by ribosome spacer PCR (RSPCR) and arbitrarily primed PCR (AP-PCR). RS-PCR generated 9 different genotypes. The use of APÐPCR provided a high resolution typing method and allowed us to define 11 different clusters. Three major clusters, however, based on the combination of both typing methods, spread throughout the neonatal and intensive care units of Rafidya Hospital during the entire period.

- Shiga toxigenic Escherichia coli (STEC) isolates from symptomatic and asymptomatic patients in northern Palestine in 1999 were screened for serotype O157 and characterised for virulence genes by multiplex PCR assay. Of the 176 STEC isolates, 124 (70.5%) were of serotype O157. All these isolates carried the gene for Shiga toxin type 1 (stx1) and 112 (90.3%) carried s tx2. The intimin encoding gene locus eae was detected in 16 isolates (12.9%) and the enterohaemolysin encoding gene, hlyA, in 18 (14.5%). Statistical analysis showed a significant association between the presence of eaeA and hlyA, either alone or combined with stx1 and stx2 genes in O157 isolates from symptomatic infection. ERIC-PCR analysis of DNA from 80 serotype O157 isolates revealed three major clonal populations.

- The surgical incidence of cystic echinococcosis (CE) due to Echinococcus granulosus was investigated in hospitals of the West Bank, Palestinian Authority between January 1990 and December 1997. Serum samples from school-children in Yata town, which showed the highest surgical incidence, were tested for anti-hydatid antibodies. A total of 390 surgically confirmed cases were recorded throughout the 8-year period, with an overall mean annual surgical incidence (MASI) of 3.1 per 100,000. A high MASI of 4.9, 5.0 and 5.1 per 100,000 was found in Hebron, Jericho and Bethlehem Governorates, respectively. Yata town, Hebron governorate, showed the highest MASI, at 16.8 per 100,000. The highest incidence was found in age groups 11-20 and 21-30 years, at 27.4% and 21.5% of the total number of cases. While there was no significant gender difference in the number of cases in the age groups of 20 years or less, the male to female case ratio was 1:3.2-4.1 in the older age groups. The liver was the most common site of hydatid

- One hundred and thirteen consecutive isolates of Streptococcus pneumoniae were collected in Nablus, Palestine between March and Aug. 1997 from children,vith acute lower respiratory tract infections. Resistance rates were: penicillin 88%, cefuroxime 85%, erythromycin 63%, tetracycline 45%, chloramphenicol 27% and ofloxacin 2%. Resistances to erythromycin and cefuroxime were significantly associated with penicillin resistance. Ofloxacin may be useful against pneumococci resistant to traditional antimicrobial agents. Factors associated with penicillin resistance included hospitalisation and previous use of beta-lactam antibiotics.
