In the North-East Indian state of Mizoram, scrub typhus cases were first recorded only in 2012. However, in the last five years, the state has seen a substantial increase in the scrub typhus and other rickettsial infections. As part of the public health response, the Mizoram Government has integrated screening and line listing of scrub typhus and other rickettsial infections across all its health settings, a first in India. Here we detail the epidemiology of scrub typhus and other rickettsial infections from 2018– 2022, systematically recorded across the state of Mizoram. 2023-11-01T00:00:00Z http://pucir.inflibnet.ac.in:8080/jspui/handle/123456789/664 Title: Morphological and molecular characterization of entomopathogenic nematode, Heterorhabditis baujardi (Rhabditida, Heterorhabditidae) from Mizoram, northeastern India Authors: Vanramliana Abstract: Isolation of entomopathogenic nematodes from Mizoram, northeastern part of India includes a Heterorhabditis species never been recorded in India. The morphological and multigene (ITS rRNA, 28S rRNA and COI) sequences analysis had revealed that the isolated Heterorhabditis belongs to Heterorhabditis baujardi, originally described from Vietnam. The phylogenetic tree (both MP and ML) revealed that the H. baujardi belongs to H. indica clade, and further, forms a monophyletic clade (99/98% and 94/92% bootstrap support for ITS and 28S respectively) with H. amazonensis, H. floridensis, H. mexicana and H. taysearae forming H. baujardi sub clade. The multigene characterization revealed that both the ITS and 28S rRNA showed similar result in resolving the phylogenetic relationship of the genus Heterorhabditis, with the ITS rRNA being superior based on the strong bootstrap support, whereas, the cytochrome c oxidase I (M1–M6 partition) can be a good supportive tool for species delimitation. This is the first report of H. baujardi from India envisaging its future use as a biological control agent, and further incorporated into the IPM. 2018-01-01T00:00:00Z
