ABSTRACT
This study has been carried out to compare antimycobacterial activity of five selected Indonesian endogenous medicinal plants of Andrographis paniculata, Annona muricata, Centella asiatica, Pluchea indica, and Rhoeo spathacea against clinical isolate of multi-drug resistant (MDR) Mycobacterium tuberculosis. The aqueous extracts of leaves of Andrographis paniculata, Annona muricata, Centella asiatica, Pluchea indica, and Rhoeo spathacea were obtained by maceration, and the phytochemical constituents of each extract were screened. Antimycobacterial activity of aqueous plant extracts were determined by proportion methods using Lowenstein Jensen (L-J) medium. Our study exhibited that all extracts of five selected plants showed inhibited activity against Mycobacterium tuberculosis H37Rv strain and multi drug resistant (MDR) strain. The proportion inhibition of aqueous extract of Andrographis paniculata, Annona muricata, Centella asiatica, Pluchea indica, and Rhoeo spathacea, against Mycobacterium tuberculosis H37Rv strain were 100%, 82.1%, 78.5%, 100%, and 100% respectively, whereas against MDR strain were 93.7%, 50.0%, 50.0%, 100%, and 100% respectively. The phytochemical analysis showed that the extracts were predominantly contains flavonoids, alkaloids, saponins, tannins and glycosides. Pluchea indica, and Rhoeo spathacea showed good antimycobacterial activity against MDR strains and could be useful as complementary alternative therapy in combating the emergence of MDR strains of Mycobacterium tuberculosis.
ABSTRACT
The spread of drug resistant microbes is a global public health challenge which impairs the efficacy of antimicrobial agents and causes substantial increase in morbidity and mortality rates, including healthcare-associated costs. Monitoring of antimicrobial drug resistance from documented microbial epidemiology & resistance rate is useful in preventing the emergence of resistance. This study reports on the pattern of bacterial resistance against ceftriaxone in the past 4 years. The data were obtained from specimens examined in the Clinical Microbiology Laboratory, Department of Microbiology Faculty of Medicine, University of Indonesia from 2002 to 2005. Microbial species were determined from culture and identification tests. Disc diffusion method was used for sensitivity testing of ceftriaxone to 14 Gram-negative and 7 Gram-positive bacteria. Although resistance rates were increased from 2002 to 2005, resistance rates of ceftriaxone were found to be less than 50%. Low resistance rates (< 3%) were observed for Salmonella typhi, Salmonella paratyphi A, Shigella flexneri, Serratia marcescens, and Streptococcus pneumoniae. These results could be useful in developing guidelines on the use of ceftriaxone in Indonesia.
