  • Identification of mature/immature stages of helminths and arthropods (gross specimens or in histological sections) from any host species. Gross specimens/samples should be submitted in 70% alcohol.

John McGarry has 30 years’ experience in a broad range of diagnostic work, with special interests in dog lungworms, ticks and tick-borne diseases, forensic entomology and wildlife parasitology.
