Malaria is endemic to Lombok Island, Indonesia. One approach to suppress malaria spread is to eliminate anopheline larvae in their habitat and the environmentally safe agent is bacteria, that is,Bacillus sphaericus. However, there is no information regarding local isolate ofB. sphaericusthat is toxic to mosquito larvae from Lombok. The aims of the study were to isolateB. sphaericusfrom soil in areas close to beach surrounding Lombok Island and to test their toxicity against 3rd instarAnopheles aconituslarvae. Soil samples were collected from 20 different sampling locations from Lombok Island and homogenized with sterile physiological salt solution. Suspension was heat-shocked at 80°C for 30 minutes and then spread onto antibiotic-supplemented NYSM solid medium. Colonies grown were characterized and subjected to initial toxicity test against anopheline larvae. Isolates with more than 50% killing percentage were subjected to bioassay testing against anopheline larvae. From 20 locations, 1 isolate showed mild toxicity (namely, isolate MNT) and 2 isolates showed high toxicity (namely, isolates SLG and TJL2) againstAn. aconitus. Those 3 isolates were potentially useful isolates, as they killed almost all larvae in 24 hours. The discovery of toxic indigenous isolates ofB. sphaericusfrom Lombok Island opens opportunity to develop a biopesticide from local resources.

ABSTRACT The ermG gene was first found in the soil bacterium Bacillus sphaericus. More recently, it was found in several human intestinal Bacteroides species. We report here the first finding of ermG genes in gram-positive bacteria isolated from porcine feces and from under-barn manure pits used to store porcine wastes. The porcine ermG sequences were identical to the sequence of the B. sphaericus ermG gene except that six of the seven ermG-containing strains contained an insertion sequence element insertion in the C-terminal end of the gene. The porcine ermG genes were found in three different gram-positive genera, an indication that it is possible that the gene is being spread by horizontal gene transfer. A segment of a Bacteroides conjugative transposon that carries an ermG gene cross-hybridized with DNA from six of the seven porcine isolates, but the restriction patterns in the porcine strains were different from that of the Bacteroides conjugative transposon.
