DETAILS OF RESEARCH INTERESTS:
Prior to my appointment
as an assistant professor at Texas
State University, I served as a microbiologist
and molecular epidemiologist for the Texas Department of State Health Services
(DSHS, formerly TDH)-Bureau of Laboratories
Control Division (ZCD) for 10 years. It was at this institution
that I developed an interest in zoonotic disease, especially with respect
to rabies. I spent much of my time performing antigenic and molecular
typing of the different variants of rabies virus. The epidemiologic
evidence gathered from this testing provided information for the Oral Rabies
Vaccination Program (ORVP)conducted by the ZCD. I still
volunteer for the ORVP team each January and I have continued to collaborate
with the DSHS and the Centers for Disease Control (CDC) in rabies efforts.
While at DSHS, I helped initiate the Regional
Reference Laboratory for Rabies Virus Variant Typing in collaboration
with the CDC. As a faculty
member at Texas State, I bring my experience from the DSHS laboratory and
ORVP efforts with respect to public health into the various courses that
I teach: clinical microbiology, clinical immunology, molecular diagnostics,
parasitology, clinical research, and seminars.

Recently, I have become interested in
antimicrobial resistance, specifically Methicillin Resistant Staphylococcus
aureus (MRSA). I have conducted collaborative projects with DSHS
in respect to the prevalence of MRSA in a Texas prison population.
I plan to continue with these research endeavors at Texas State University
while investigating other issues with respect to clinical diagnosis of infectious

Rabies virus causes an acute encephalitis in all warm-blooded hosts, including humans, and the outcome is almost always fatal. Although all species of mammals are susceptible to rabies virus infection, only a few species are important as reservoirs for the disease. In the United States, several distinct rabies virus variants have been identified in terrestrial mammals, including raccoons, skunks, foxes, and coyotes. In addition to these terrestrial reservoirs, several species of insectivorous bats are also reservoirs for rabies.
Rabies virus belongs to the order Mononegavirales, viruses with a nonsegmented, negative-stranded RNA genome. Within this group, viruses with a distinct "bullet" shape are classified in the Rhabdoviridae family, which includes at least three genera of animal viruses, Lyssavirus, Ephemerovirus, and Vesiculovirus. The genus Lyssavirus includes rabies virus, Lagos bat, Mokola virus, Duvenhage virus, European bat virus 1 & 2 and a newly discovered Australian bat virus.
Rabies is a preventable viral disease of mammals most often transmitted through the bite of a rabid animal. The vast majority of rabies cases reported to the CDC each year occur in wild animals like raccoons, skunks, bats, and foxes. Domestic animals account for less than 10% of the reported rabies cases, with cats, cattle, and dogs most often reported rabid.
Rabies virus infects the central nervous system, causing encephalopathy and ultimately death. Early symptoms of rabies in humans are nonspecific, consisting of fever, headache, and general malaise. As the disease progresses, neurological symptoms appear and may include insomnia, anxiety, confusion, slight or partial paralysis, excitation, hallucinations, agitation, hypersalivation, difficulty swallowing, and hydrophobia (fear of water). Death usually occurs within days of the onset of symptoms.
Most of the recent
human rabies cases in the United States have been caused by rabies
virus from bats. Awareness of the facts
about bats and rabies can help people protect themselves, their families,
and their pets. When people think about bats, they often imagine
things that are not true. Bats are not blind. They are neither rodents nor
birds. They will not suck your blood -- and most do not have rabies. Bats
play key roles in ecosystems around the globe, from rain forests to deserts,
especially by eating insects, including agricultural pests. The best protection
we can offer these unique mammals is to learn more about their habits and
recognize the value of living safely with them.
