Abstract

Mycobacterium ulcerans is a pathogen that causes Buruli ulcer a necrotic skin disease prevalent throughout Western Africa and studies indicate that aquatic insects could be transmitting this pathogen. Studies conducted show that crude extracts from the green algae added to BACTEC 7H12B culture medium, reduced to half.

Abstract

Research has been conducted on the role of water insects as Mycobacterium ulcerans host. Results indicate that M. ulcerans can be transmitted to the laboratory mice via the aquatic bug bite.

Abstract

A few aquatic snails that may transitorily harbor Mycobacterium ulcerans without offering favorable conditions for its growth and replication are reported. Results indicate that no mycobacterial growth was detected in aquatic snails and so they may be a passive host of M. ulcerans and other environmental mycobacteria.

6. Isolation of Three Mycobacterium ulceransStrains Resistant to Rifampin after Experimental Chemotherapy of Mice

Abstract

ABSTRACTBy use of a murine model for Buruli ulcer, Mycobacterium ulceranswas found to be susceptible to rifampin, with the MIC being 0.5 to 1 μg/ml. Three mutants were isolated after rifampin monotherapy. Two were resistant to rifampin at 8 μg/ml, and one was resistant to rifampin at 32 μg/ml. The mutants harbored Ser416Phe mutations and His420Tyr mutations in the rpoBgene, and these mutations have also been found to be responsible for rifampin resistance in the leprosy and tubercle bacilli. The results indicate that while rifampin may be active against M. ulcerans, it should never be used as monotherapy in humans.

Abstract

Accumulative indirect evidence of the epidemiology of Mycobacterium ulcerans infections causing chronic skin ulcers (i.e., Buruli ulcer disease) suggests that the development of this pathogen and its transmission to humans are related predominantly to aquatic environments. We report that snails could transitorily harbor M. ulcerans without offering favorable conditions for its growth and replication. A novel intermediate link in the transmission chain of M. ulcerans becomes likely with predator aquatic insects in addition to phytophage insects. Water bugs, such as Naucoris cimicoides, a potential vector of M. ulcerans, were shown to be infected specifically by this bacterium after feeding on snails experimentally exposed to M. ulcerans.
