A 63-year-old, white, animal caretaker suffered intermittent abdominal pain and diarrhea of 3 weeks duration. Hematological findings included leukocytosis (18,600) with eosinophilia (73%). Fecal examination revealed Stongyloides rhabditiform larvae which on culture yielded a preponderance of filariform larvae and a few free-living adults. Thiabendazole therapy resulted in rapid recovery. Epidemiological investigation yielded no history of previous Strongyloides infection or exposure; his wife and pet dog were not infected, but about one-third of the dogs in the colony under his care were found to be discharging Stongyloides rhaditiform larvae in their feces. Strongyloides infection was successfully trasmitted to specific pathogen-free pups using filariform larvae derived both from the human case and from the dog colony. Specimens recovered from one pup infected with filariform larvae of human origin were identified as Strongyloides stercoralis.

Three hundred and thirty-two stool samples were examined for the presence of intestinal parasites including Strongyloides stercoralis. Each sample was processed and examined by direct smear, formalin-ether and Harada and Mori culture methods. Nine parasites were recovered from patients attending Basrah Teaching Hospital, southern Iraq during 1989. The prevalence rate of infection was 64.2%. It was higher in rural (74.2%) than in urban (57.5%) region (p < 0.01). Sex distribution was 120 (36.1%) males and 87 (26.2%) females (p > 0.05). The most common parasites were Blastocystis hominis, Giardia lamblia, Entamoeba histolytica, Hymenolepis nana and Strongyloides stercoralis. Formalin-ether concentration method was 3.75 times better than the direct smear method in the diagnosis of helminth rather than protozoan infections. The yield obtained by the usage of the Harada and Mori culture method (4.5%) was significantly higher than that obtained by formalin-ether (2.7%) or direct smear (0.3%) methods. Therefore, the Harada and Mori culture method is recommended in patients with undiagnosed diarrhea and where strongyloidiasis is endemic or suspected. Investigation of the relationship between age of the patients and prevalence showed that the prevalence of total intestinal parasites and of Strongyloides alone had essentially levelled off by age 11-20 and 21-30 years old, respectively. Clinical symptoms associated with S. stercoralis infection were diarrhea, anorexia and abdominal pain. Thiabendazole is still a drug of choice in the treatment of strongyloidiasis.
