The spread of drug-resistant Plasmodium falciparum (PF) has made essen
tial the research of new effective therapies like antibiotics. Tetracy
clines have been used in South-East Asia in combination with quinine a
s a curative therapy or alone as a chemoprophylaxis in PF malaria; its
tolerance seems to be acceptable. In PF malaria, clindamycin appears
to be well effective in the cure of semi-immune subjects, and increase
s quinine activity; diarrhea could occur less frequently than expected
. Because of a low intaerythrocytic concentration, fluoroquinolone ant
ibiotics don't have a sufficient activity. Azithromycine may be more e
ffective than other macrolides. Howether, wider use of antibiotics in
malaria is hindered by studies difficulties and possible consequences
for bacterial diseases.
