Abstract

At Kowanyama, 104,006 adult female mosquitoes of a probable 47 species were collected on twelve occasions from April, 1972, to April, 1976. At Charleville, 71,791 adult females of 20 taxa were taken during thirteen periods from February, 1974, to February, 1976. Culex annulirostris was predominant at Kowanyama and especially at Charleville where it comprised up to 99% of dry season collections. Culex fatigans, Ae normanensis, An annulipes and, at Kowanyama only, An bancroftii were the other major species collected. Several bait trapping methods were suitable for monitoring densities of Cx annulirostris and other species but mammalian baits were best. Because Cx annulirostris activity continued throughout winter even at Charleville, continuous cycles of arbovirus transmission are possible, although the potential of dormant Aedes eggs also bears investigation as a method of arbovirus survival.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
