Kevin Macaluso from Louisiana State University to be featured speaker on April 10

By Doris Merrill

Kevin Macaluso, associate professor of pathobiological sciences in the School of Veterinary Medicine at Louisiana State University, is presenting a seminar co-sponsored by the entomology department, the Marty Vanier and Bob Krause Biosecurity Research Institute Research Fellows Program, and the Center of Excellence for Vector-Borne Diseases. 

Macaluso will present "Rickettsial Determinants for Arthropod Infection and Transmission" at 4 p.m. Tuesday, April 10, in the Lecture Hall at the Biosecurity Research Institute, Pat Roberts Hall. Refreshments will be served at 3:30 p.m.

Presentation abstract: The increase in reported rickettsial infections globally coincides with the discovery of unfamiliar arthropod vectors, newly recognized rickettsial pathogens, and documented transmission potential of what have been considered to be rickettsial symbionts. Thus, the transmissibility of rickettsiae, vectorial capacity, and the classification of rickettsial pathogens can be considered variables contributing to emerging rickettsial infections. Using multiple Rickettsia species, we are examining the rickettsial determinants of vector infection and transmission. For emerging and re-emerging flea- and tick-borne rickettsial agents, recent studies have identified novel aspects of transmission biology.
