Dr. Kaplan is
an Associate Professor in the Department of
Infectious Diseases in the College of Veterinary
Medicine at the University of Georgia. Prior to
his position at University of Georgia, Dr.
Kaplan served in the Army Veterinary Corps at
the Walter Reed Army Institute of Research where
he was Chief of Parasite Biology in the Division
of Experimental Therapeutics. Dr. Kaplan
received his bachelor’s degree from Virginia
Tech and his DVM from Virginia-Maryland Regional
College of Veterinary Medicine. He worked as a
clinical veterinarian in a mixed-species private
practice in Pennsylvania for several years
before leaving practice for the University of
Florida where he earned a PhD in Veterinary
Parasitology. Since 1998 he has been in his
current position where he teaches and performs
research in veterinary and human medical
parasitology. Dr. Kaplan is principal
investigator and director of the Filariasis
Research Reagent Resource Center (FR3), and is
director of the Athens Parasitology Diagnostic
Laboratory.
The primary
research focus of his laboratory is to measure,
understand, and solve the problems presented by
drug-resistant parasites. Over the past forty
years, the availability of cheap and effective
anthelmintic drugs has led to an almost complete
reliance on these chemicals for parasite control
in animals. Chemical-based parasite control was
extremely effective for many years, but we now
know that this strategy has turned out to be
shortsighted and unsustainable. Parasite drug
resistance is now recognized globally as one of
the greatest health threats to grazing
livestock. Also, in recent years there has been
a dramatic increase in the use of mass drug
administration to reduce the morbidity
associated with helminth parasite infections of
humans, raising the likelihood that anthelmintic
resistance may become a public health concern in
the near future.
To address
these problems, Dr. Kaplan’s laboratory pursues
research projects with several different areas
of emphasis:
1. Measuring
the prevalence of drug resistance
2. Studying the molecular basis of anthelmintic
resistance
3. Developing molecular diagnostic assays to
detect emerging resistance in nematode
populations
4. Developing and optimizing in vitro diagnostic
assays to detect and measure clinically relevant
levels of anthelmintic resistance
5. Studying and developing novel and sustainable
approaches to parasite control that deemphasize
chemical control
6. Developing improved methods for evaluating
and understanding fecal egg count data,
especially as relating to diagnosing resistance
using the fecal egg count reduction test
