Serological assays were used to estimate the proportion of Acalymma vittata (F.) that harbored Erwinia tracheiphila (E. F. Smith) Holland, the causal agent of bacterial wilt in cucurbits. Theseproportionswere related to theproportionofA. vittata that transmitteddisease in singlebeetle caged bioassays. The serological assays classiÞed beetles as harboring the bacteria when the titer was above '1...
In recent years, viral epidemics such as the coronavirus disease (COVID-19) have spread, and this outbreak is thought to be the result of animal-to-human transmission. Hence, accurate diagnostic tests to detect COVID-19 and antiviral antibodies in infected individuals are of utmost importance. This report describes the structure, history, taxonomy, and molecular and immunological techniques for...
BACKGROUND: Sporadic outbreaks of bovine trypanosomiasis have been reported in Bolivia since 1996 when T. vivax and T. evansi were identified for the first time by parasitological means. However, comprehensive epidemiological information concerning T. vivax and T. evansi in the country is lacking. Current parasitological and serological diagnostic methods for trypanosomiasis have important limi...
Isolated islands provide valuable opportunities to study the persistence of viruses in wildlife populations, including population size thresholds such as the critical community size. The straw-coloured fruit bat, Eidolon helvum, has been identified as a reservoir for henipaviruses (serological evidence) and Lagos bat virus (LBV; virus isolation and serological evidence) in continental Africa. H...
BACKGROUND Two important challenges to the use of serological assays for influenza surveillance include the substantial amount of experimental effort involved and the inherent noisiness of serological data. RESULTS I show that log-transformed serological data exist in an effectively one-dimensional space. I use this result, together with new mechanistic insights into serological assays, to de...
