Abstract

Between 1971 and 1974 546 wild animals of 34 species were examined for trypanosomes; 79 infections (9 mixed) were diagnosed and 29 stocks were cryopreserved. Of 14 stocks of the subgenus Trypanozoon tested by the blood incubation infectivity test three (two from Kobus ellipsiprymnus and one from Phacochoerus aethiopicus) retained their infectivity to rodents. There are indications that the number of animals harbouring trypanosomes is far in excess of those showing detectable parasitaemias even when using a combination of diagnostic methods. The standard microhaematocrit method involving microscopic examination of the buffy layer from a microhaematocrit tube between a slide and coverslip, and the inoculation of experimental animals produced the most satisfactory results.

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.

Sexual Dimorphism in Neurodegeneration

There exist sex differences in neurodevelopmental and neurodegenerative disorders. For instance, multiple sclerosis is more common in women, whereas Parkinson’s disease is more common in men. Here is the latest research on sexual dimorphism in neurodegeneration
