Activity of sparfloxacin against Mycobacterium leprae inoculated into footpads of nude mice.
The antileprosy activity of a new quinolone, sparfloxacin, was examined in the nude mouse footpad model. By serial dosing (once a day, 5 or 6 times per week, during the 3rd-5th months postinoculation), 10 mg/kg of sparfloxacin displayed bactericidal-type activity and bacteriostatic activity was present at daily doses of 5 and 2 mg/kg. By intermittent dosing (once a day, twice weekly at daily do...
متن کاملExperimental leprosy with nude mice.
In 1960, Shepard10) reported a model of experimental leprosy of mouse by means of footpad inoculation technic. This experimental leprosy has been widely utilized in the field of leprosy research, but grwoth of Mycobacterium leprae in normal mouse foot-pad is limited and maximum harvest of M. leprae from infected normal mouse foot-pad is about 106. Several studies were reported concerning immuno...
متن کاملMycobacterium leprae in Mouse Peritoneal Macrophages
Mycobacterium leprae synthesizes large quantities of a specific phthiocerol-containing phenolic glycolipid in vivo. We had shown earlier that viable M. leprae readily incorporates radiolabeled palmitic acid into phenolic glycolipid I when residing in cultured macrophages in vitro and that this process is inhibited by the antileprosy drug rifampin. In the present paper we report the application ...
متن کاملImpaired responses to Mycobacterium leprae antigens in rhesus monkeys experimentally inoculated with simian immunodeficiency virus and M. leprae.
Seven of eight rhesus monkeys (RM) coinfected with simian immunodeficiency virus (SIV) and Mycobacterium leprae harboured acid-fast bacilli (AFB) at sites of dermal inoculation and/or at disseminated sites at times of humane sacrifice (up to 270 days post-M. leprae inoculation) due to SIV-induced debilitation or, in one long term survivor's case, to date over 3 years post-M. leprae inoculation....
متن کاملDetection of IgA anti-PGL-I specific antigen to Mycobacterium leprae in mangabey monkeys inoculated with M. leprae.
Using sera from 4 pairs of mangabey monkeys inoculated with titrated doses of Mycobacterium leprae we demonstrated that IgA antibodies against M. leprae specific PGL-I antigen were present in 75% of inoculated monkey's sera. High IgA antibody was detected in 50% (3/6) of infected animals and all three developed lepromatous leprosy (LL). Antibody titers correlated with PGL-I antigen in serum. Th...
