The detection of antibodies to hookworm larva in patients by immunofluorescence: a preliminary report

Abstract

Using the fluorescent antibody technique 84% of patients with severe hookworm infection and 74% of Nigerian blood donors have detecable antibodies that react with surface antigen of hookworm larvae. On the other hand only 24% of Nigerian medical students and 20% of Caucasians (Canadians) have such antibodies in their sera. It is suggested that while the results of tests on students may be due to the relatively infrequent contact with hookworm the antibody positivity in the Caucasians may be due to cross reaction with other related helminths. The titre of antibody produced in the hookworm infected patients was similar to that of the blood donors but differed from other groups. Lower positivity rates were observed with further dilution of sera in the hookworm infected patients. This may be due to their relative incapacity to produce potent hookworm antibody. Further work on this aspect is required as well as improvement of the specificity of the technique.

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.
