Cold agglutinins in HIV-seropositive participants and diagnosis of respiratory disease due to Mycoplasma pneumoniae.

Objectives: Cold agglutinin (CA) titers are one among the first pathological indicators for diagnosing Mycoplasma pneumoniae disease. We prospectively studied the prevalence of CAs in 300 HIV-positive and 75 HIV-negative individuals with respiratory disease in Chennai, India.

Methods: The cold agglutination test was used and retrospectively compared with the results of a particle agglutination test.

Epidemiological studies on pulmonary pathogens in HIV-positive and -negative subjects with or without community-acquired pneumonia with special emphasis on Mycoplasma pneumoniae.

The prevalence of Mycoplasma pneumoniae among HIV-positive patients with community-acquired pneumonia (CAP) remains unclear. We investigated 300 HIV-positive adults (200 with CAP and 100 with no respiratory illness) and 75 HIV-negative adults with CAP for the prevalence of respiratory pathogens using culture and serology. A growth inhibition test was employed to confirm the isolates of M.

Prevalence of Campylobacter jejuni and enteric bacterial pathogens among hospitalized HIV infected versus non-HIV infected patients with diarrhoea in southern India.

A prevalence study on Campylobacter jejuni and other enteric bacterial pathogens was carried out in 200 HIV infected and 200 non-HIV infected subjects with diarrhoeal symptoms at an AIDS Hospital in southern India. Diarrhoeal specimens were inoculated onto standard culture media as well as onto Columbia and Campylobacter blood agar media for C. jejuni isolation.

Seroprevalence of Mycoplasma pneumoniae in HIV-infected patients using a microparticle agglutination test.

Mycoplasma pneumoniae is increasingly recognized as a common and important pathogen in community settings, and is responsible for various pulmonary and extrapulmonary conditions in the normal population. However, the seroepidemiology of acute M. pneumoniae infection in HIV-infected individuals is still unclear worldwide.
