Paul and the Mosquitos

30 July 2021 by Vincent Racaniello

From the authors of Paul Has Measles and Paul Stays Home comes Paul and the Mosquitos, an illustrated book for children about mosquito-borne diseases.

In his camp, Paul and his friends discuss which is the most dangerous animal of all. They would never have imagined it would be the mosquito. Why are they dangerous and what can we do to prevent the diseases transmitted by them?

Paul and the Mosquitoes is written by Susana López, Selene Zárate, and Martha Yocupicio, with illustrations by Eva Lobatón.

A pdf of Paul and the Mosquitos can be downloaded free of charge here.

Inter-kingdom interactions in the mosquito gut

7 February 2019 by Vincent Racaniello

Biting mosquitoThe gut tracts of many animals are inhabited by a microbial community composed of bacteria, archaea, fungi, and viruses. The interplay among these inhabitants can have an impact on health and disease. Mosquitoes are no exception – replication of dengue virus in the gut tract is modulated by a fungus and a bacterium.

Mosquito blood feeding is not a free lunch

15 March 2018 by Vincent Racaniello

Wyeomyia smithiiImagine that we could change all the mosquitoes in the world so that they would no longer take a blood meal, and then consider the impact on transmission of viruses and parasites. Before you say impossible, you should know that Nature has already done it – not all mosquitoes take blood meals.
