Dr. Marks is a veterinary gastroenterologist and nutritionist who runs the Companion Animal Gastrointestinal Laboratory. His research group have been characterizing enteric bacteria (Clostridial species, Campylobacter, Salmonella) and protozoa (Giardia, Cryptosporidium, Tritrichomonas foetus) associated with diarrhea in dogs and cats, and evaluating diagnostic tests and therapeutic strategies to eradicate the organisms. His group has also studied antimicrobial susceptibilities of Clostridium isolates to commonly utilized antimicrobial drugs, and evaluated the incidence of antimicrobial resistance genes in canine Clostridium perfringens isolates. The GI laboratory is fully equipped for performing aerobic and anaerobic microbiology, parasitology examinations, DNA extraction and purification, PCR, gel electrophoresis, and immunoassays. The laboratory has several ongoing studies evaluating the protozoan, Tritrichomonas foetus, an important cause of bovine infertility and abortion, and a recently characterized cause of chronic diarrhea in cats.
If you are interested in being involved in the laboratory and are fascinated with research, learning new laboratory skills, and becoming more knowledgeable in the field of infectious diseases of the gastrointestinal tract, please contact Dr. Stanley Marks at slmarks@ucdavis.edu.
