Published: August 2022

The antigenic heterogeneity of Orientia in India is still unknown in many disease endemic areas. The present study aims to characterize the strains of O. tsutsugamushi circulating in Nagaland, Northeast India. Two patients clinically diagnosed with ST and hospitalized in Mon district hospital, Nagaland were identified from whom eschar tissues were collected. Both patients demonstrated antibodies against O. tsutsugamushi along with positive PCR amplification for 56 ​kDa gene. The prototype strain TA763 shared 90.4% homology with the sequences. Both the sequences formed a distinctive cluster demonstrating 100% similarity with strains identified from Thailand, Vietnam, China and southern parts of India.

Article Synopsis
  • - The study explores cases of Chikungunya virus (CHIKV) and Dengue virus (DENV) co-circulating in Punjab, India, highlighting the challenges clinicians face due to overlapping symptoms and similar mosquito vectors in tropical environments.
  • - A total of 370 suspected arboviral cases were analyzed, revealing that 38.3% were confirmed as Chikungunya, predominantly affecting young males, with symptoms like polyarthralgia and headache, alongside a significant occurrence of co-detection of both viruses.
  • - The findings underscore the necessity for improved differential diagnosis techniques for arboviruses, particularly as many patients initially diagnosed with Dengue were discovered to have Chikungunya, indicating a need

Lumpy skin disease (LSD) is a disease of cattle that is also known to cause mild infection in buffaloes. To date, there have been no reports of LSD in mithun (Bos frontalis), a bovine species distributed in Northeast India, Bangladesh, Myanmar, and parts of China. In the present study, the presence of typical clinical signs, virus isolation, PCR amplification, sequence analysis, and the demonstration of antibodies in serum by indirect enzyme-linked immunosorbent assay and serum neutralization test, confirmed the occurrence of LSD in mithun for the first time in India.
