Arbovirus isolations from mosquitoes in South Slovakia

Area of Science:

• * Medical entomology and virology.
• * Arbovirus surveillance and public health.

Background:

• * Mosquitoes and other Diptera are known vectors of various viruses.
• * Previous studies have identified Tahyna virus and Calovo virus in insect populations.

Purpose of the Study:

• * To investigate the presence of viruses in mosquito and other Diptera populations in 1973 and 1975.
• * To identify specific virus strains and their mosquito vectors.

Main Methods:

• * Collection and processing of mosquitoes, horseflies, blackflies, and sheep keds for virus isolation.
• * Virus isolation and identification techniques were employed.

Main Results:

• * In 1973, five strains of Tahyna virus were isolated from Aedes vexans mosquitoes.
• * In 1975, twelve strains of Calovo virus were isolated from Anopheles maculipennis, and one strain of Tahyna virus was obtained from Aedes vexans.

Conclusions:

• * Aedes vexans mosquitoes are confirmed vectors of Tahyna virus.
• * Anopheles maculipennis mosquitoes are identified as vectors of Calovo virus.
• * The findings contribute to understanding arbovirus circulation in the studied region.
