“During the monsoon malaria-transmission season of 1978, infrequent feeding on humans coupled with reduced anopheline life expectancy contributed to low estimates of the malaria vectorial capacity for Anopheles culicifacie and…[Read more] -

1. What is the benefit of cell culture?
Cell culture is one of the techniques to study cell proliferation and understand their model system. This technique is widely used for investigating the cell under controlled conditions, generally outside of their neutral environment like when we needed to research virus biology, vaccine development, the…[Read more] -
Vanutsarin Khongsrisak replied to the topic TMEN 513-22 Vector and pathogen relationship in the forum TMEN 513 Medical Entomology (2022) 1 year, 11 months ago
Malaria is caused by Plasmodium parasites, which are transmitted through the bites of infected female Anopheles mosquitoes. On the other hand, culicine mosquitoes(Aedes, Culex, and Mansonia mosquito) can be important vectors for human pathogens and feed on humans like the Anopheles mosquito. For this reason, it raises the question of Why Aedes…[Read more]

Vanutsarin Khongsrisak replied to the topic TMEN 513-9 Mosquitoes II: factors influence disease transmission in the forum TMEN 513 Medical Entomology (2022) 1 year, 11 months ago
The transmission mechanism of pathogens by mosquitoes consists of three patterns. The first is eggs. Infected female mosquitoes can spread the pathogen through eggs. The pathogen emerges in the embryo or on the egg surface. Both male and female mosquitoes can become infected. We call this Vertical transmission. The second is a bite. An infected…[Read more]

Sand flies are small insects in Order Diptera, Suborder Nematocera, Family Psychodidae, and Subfamily Phlebotominae. They prefer to live in tropical, subtropics, and warm mainland regions. The sandfly’s life cycle begins with eggs, larvae, pupa, and adults. The general characteristics of the adult sand fly are small hairy flies. It has large dark…[Read more]

1. How the mosquito can transmit the pathogen?
The transmission of the pathogen by mosquito vectors can occur in 3 ways during the activity or life cycle of the mosquito such as lay eggs, biting, and mating. The first one is Vertical Transmission, which occurs when the female mosquito passes the pathogen to its embryo. And made the next…[Read more]
