Background: Ureaplasma species (Usp) are the most prevalent genital Mycoplasma isolated from the urogenital tract of both men and women. Usp may be commensals in the genital tract but may also be contributors to a number of pathological conditions of the genital tract. Because they can also just colonize the genital tract of healthy people, their pathogenic role can be difficult to prove.

Objectives: The aim of the study was to evaluate the efficacy of a quantitative polymerase chain reaction (qPCR) method for the discrimination between infection and colonization by measuring prevalence of Usp in asymptomatic versus symptomatic patients.

Methods: Urine samples were tested for U. parvum and U. urealyticum using a semi-quantitative multiplex PCR technique for sexually transmitted diseases (Anyplex™ STI-7 Detection Kit, Seegene, South Korea). A total of 250 symptomatic and 250 asymptomatic controls were included.

Results: A strong positive result for U. parvum was significantly more prevalent in symptomatic compared to asymptomatic patients. This finding was observed especially in women and in the young group (15–35 years of age). No significant differences were observed between the prevalence in symptomatic and asymptomatic patients of U. parvum with low strength of positivity and for U. urealyticum in all groups by age, gender, and strength of positivity.

Conclusions: The significant difference between the symptomatic and asymptomatic group in the highest positivity group for U. parvum using the Anyplex™ STI-7 detection kit in urine may indicate a high probability of infection rather than colonization, especially in women and young patients.

Background: Israel, as a country of immigration, has a heterogeneous distribution of risk for human immunodeficiency virus. Therefore, general population-based surveys of sexual behaviors among young adults may be useful for guiding prevention policy. To the best of our knowledge, the present survey is the first one among Israeli adults ever published.

Objectives: To survey knowledge, attitudes and practices regarding sexually transmitted infections in Israeli adults in order to target the future AIDS public campaigns for the general population.

Methods: A national sample of 800 individuals, aged 18–45, was interviewed telephonically in September 2000.

Results: The average number of sexual partners reported in the previous 3 months was 1.3. Accurate knowledge on HIV[1] transmission modes was expressed by 99% of respondents for unprotected sexual intercourse, 97% for re-use of needles and syringes, and 85% for mother-to-child infection. However, incorrect notions on transmission were also prevalent (34% for insect bites, 29% for kissing and 21% for public toilets). Prevention of STIs[2] and prevention of pregnancy were the most common reasons for using condoms (72–73%); HIV prevention was the motivation for 39%. Fifty percent of single individuals without steady partners always/usually used condoms. It was decided that women need empowerment to negotiate condom use.

Conclusions: Gaps were found between knowledge (at high level), attitudes (perceiving greater risk for others than themselves) and behavioral practices (combining low level of partner exchange with widespread disregard for safe sex). Promptly implemented, these findings will serve as a baseline for further surveys.
