Complete genomic sequences of Venezuelan equine encephalitis virus subtype IIID isolates from mosquitoes.

Abstract: Venezuelan equine encephalitis virus (VEEV) is an important pathogen of medical and veterinary importance in the Americas. In this report, we present the complete genome sequences of five VEEV isolates obtained from pools of Culex (Melanoconion) gnomatos (4) or Culex (Melanoconion) pedroi (1) from Iquitos, Peru. Genetic and phylogenetic analyses showed that all five isolates grouped within the VEEV complex sister to VEEV IIIC and are members of subtype IIID. This is the first report of full-length genomic sequences of VEEV IIID.

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

This research reports the complete genomic sequences of five Venezuelan equine encephalitis virus (VEEV) isolates from mosquitoes in Iquitos, Peru, which fall into the subgroup IIID. This marks the first time the entire genome of VEEV IIID has been sequenced and analyzed.

Objective and Methodology

  • The primary purpose of the research was to acquire and analyze the complete genomic sequences of five Venezuelan equine encephalitis virus (VEEV) isolates. These isolates were all found in a species of mosquito in rural Peru. VEEV is a virus that can cause serious illness in both humans and animals.
  • The VEEV isolates analyzed for this study were obtained from pools of two types of Culex mosquitoes, Culex (Melanoconion) gnomatos and Culex (Melanoconion) pedroi. These mosquitoes commonly inhabit regions of the Americas, where the virus is prevalent.

Findings

  • The researchers performed genetic and phylogenetic analyses of all five isolates and found that they all grouped within the VEEV complex, indicating that they are closely related genetically.
  • The isolates were all found to be members of the subtype IIID, based on their genetic markers and sequences. This subtype is one among several that compose the larger grouping of VEEV viruses.

Significance

  • The report is of particular importance because it marks the first time that the complete genomic sequences of VEEV subtype IIID have been described and documented. Previous studies have not fully sequenced or analyzed this specific subtype.
  • The findings broaden our understanding of the genetic makeup, variability, and evolution of the VEEV virus, particularly within the IIID subtype. This detailed knowledge could aid in vaccine development, early detection, and treatment strategies.
