In either case, the best strategies for preventing PID are: a) prevention of lower-genital-tract infection with Chlamydia trachomatis and Neisseria gonorrhoeae among both men and women, b) when this fails, early detection of lower-tract infection followed by prompt and effective treatment. (cdc.gov)

Following anti-TB treatment, alveolar macrophages, a type of immune cell located in the airways of mice and humans and the first cell to encounter Mtb upon infection, were compromised in their ability to kill Mtb . (rimuhc.ca)

They found that while all three drugs significantly altered the composition of the mice's gut microbiome, only mice treated with isoniazid combined with pyrazinamide showed an increase in susceptibility to Mtb infection. (rimuhc.ca)

In particular, it is unclear whether non-traditional routes of infection, such as those seen in this outbreak among MSM, lead to natural immunity that prevents re-infection. (medicaltrend.org)

Treating all sexual partners is essential to prevent re-infection. (medlineplus.gov)

The research also blows new holes in the idea of so-called 'herd immunity', the proponents of which believe everyone should contract the virus, hopefully beat it and therefore become immune to any subsequent infection. (rt.com)
Glatter added that extensive studies are needed to "evaluate the spectrum of illness and degree of immunity achieved due to the re-infection by the virus. (newslivetv.com)

ABSTRACT We selected 405 children aged 1-10 years with Giardia lamblia infection but without abdominal or gastrointestinal complaints for the previous month. (who.int)
