Development of acceptable and effective HIV-prevention products depends on understanding the interaction between characteristics of the products and the characteristics and perceptions of women. Levels of sexual risk and acceptability factors based on drug-use patterns, race and ethnicity, culture, age, and types and attitudes of male partners suggest that a "one size fits all" approach will not win broad acceptance among drug-involved women.

HIV transmission through heterosexual contact remains the greatest risk factor for women globally. Topical microbicides applied intravaginally may offer a female-initiated HIV prevention option for many who are unable or unwilling to use male condoms or who would want additional protection. This article presents results of focus groups in Bridgeport, Connecticut, Providence, Rhode Island, and San Juan, Puerto Rico, with women who use crack or heroin or have male partners who inject illegal drugs. Participants revealed motivation for and openness to using microbicides effective against HIV should they become available. Additional lubrication during intercourse was one of several expected positive features of microbicides; women saw lubrication as a means of enhancing pleasure and reducing condom irritation and breakage while also protecting them from infection. Conversely, some women feared that their male partners would interpret excessive lubrication as an indication of infection, improper hygiene, or evidence of sex with another man. Focus groups also provided insight into how aspects of different women's sexual lives, including partner type, might influence the issues that would concern them if and when they tried out new microbicidal products in the future.

As a subgroup of men who have sex with men (MSM), non-gay-identified (NGI) behaviorally bisexual Latino MSM are associated with heightened probabilities of HIV transmission, yet they have eluded HIV/AIDS interventionists. This exploratory study of Puerto Rican MSM drug users employed multi-session qualitative interviews to examine early life experiences related to gender identity and sexual orientation, and the place of risky drug and sexual behaviors in the process of sexual identity formation. NGI participants experienced sexual debut between ages 13 and 20, and most were recruited to prostitution as young teens by NGI age mates who were also members of drug use networks. Participants emphasized their role as insertive sexual partners and that they maintained relationships with pasivo biological males. It is feasible to recruit NGI MSM through primary male sexual partners and drug use networks. HIV/AIDS prevention based on awareness of developmental histories holds promise for intervening before NGI youth engage in male prostitution or injection drug use.

We tested serum samples collected in 1997 and 1998 from a cohort of 204 injection drug users (IDUs) recruited from Central and East Harlem, New York City, New York, for antibodies reactive with seven rickettsial or Bartonella spp. antigens. Rodent-associated Bartonella elizabethae and Rickettsia akari were the primary etiologic agents of interest. The testing panel also included Bartonella henselae, Bartonella quintana, Rickettsia prowazekii, Rickettsia rickettsii, and Rickettsia typhi. The highest prevalence of seroreactive serum samples (46%) was found with B. elizabethae antigens; 10% of the samples reacted with B. henselae antigens, while 2% reacted with B. quintana antigens. Reactivity to the latter two antigens was likely due to cross-reactivity with B. elizabethae antigens in most instances. Among the spotted fever group rickettsiae, 18 (9%) samples reacted with R. akari, including 10 samples (5%) that also reacted with R. rickettsii. Cross-adsorption studies demonstrated that most of the spotted fever group rickettsiae antibodies were due to R. akari infections. Among the typhus group rickettsiae, 5 samples reacted weakly to R. prowazekii antigens, and no samples reacted with R. typhi antigens. These findings suggest that Harlem IDUs are commonly exposed to two rodent-associated zoonotic agents. Further study of IDU populations may help elucidate transmission cycles of these agents in inner cities where higher levels of transmission occur.
