A cultivable bacterial community composed of Enterobacteriaceae, Enterococcaceae, and Bacillaceae was identified in the intestinal tract of B. dorsalis. Metabolites from B. cereus attracted the greatest number of B. dorsalis adults in the laboratory and field. These results provide useful information for the development of bacterial biocontrol agents or implementation as an insecticide.

Worldwide, M.tb infects more humans than any other single bacterial agent. The World Health Organization estimates there are 8-9 million new cases of clinical TB and 2 million deaths resulting from this disease every year (1). One third of the world's population is infected by M.tb but only about 10% of those infected develop clinical disease (2), which suggests that host genetic factors play a role in TB susceptibility. Therefore, it is important to identify and elucidate the genetic background and factors contributing to the development, clinical manifestations and outcome of TB (3). Polymorphisms in several cytokine genes have been described, and demonstrated to influence Correspondence Jun Yue,
