Summary
Dog endoparasite prevalence significantly decreased from 1981 to 1990, with notable declines in ascarids like Ancylostoma spp. However, Giardia spp. prevalence increased, indicating ongoing parasitic challenges in canine populations.
Area of Science:
- Veterinary Parasitology
- Canine Health
- Epidemiology
Background:
- Endoparasitic infections pose a significant threat to canine health and welfare.
- Understanding temporal trends in parasite prevalence is crucial for effective control strategies.
- Ascarid infections, including Toxocara spp. and Trichuris spp., are common in dogs.
Purpose of the Study:
- To determine the prevalence of endoparasites in dogs examined at a veterinary teaching hospital from 1981 to 1990.
- To analyze trends in the prevalence of specific endoparasitic species over a decade.
- To identify changes in the prevalence of common canine parasites, including ascarids and heartworms.
Main Methods:
- Fecal and blood examinations were conducted on approximately 1,250 fecal and 900 blood specimens annually.
- Data collection spanned from 1981 to 1990 at the Oklahoma State University veterinary medical teaching hospital.
- Prevalence rates for various endoparasitic species were calculated and compared across the study period.
Main Results:
- Overall endoparasite prevalence in dogs decreased from 55% in 1981 to 36% in 1990.
- Significant decreases were observed in Ancylostoma spp. (39% to 15%), Toxocara spp. (8% to 4%), and Trichuris spp. (12% to 9%).
- Giardia spp. prevalence increased, while Dirofilaria spp. showed fluctuating trends, and Dipetalonema spp. decreased.
Conclusions:
- Canine endoparasite prevalence, particularly ascarids, showed a downward trend during the study period.
- Despite decreasing prevalence, environmental contamination with parasite eggs remains a concern due to their longevity and fecundity.
- Increased Giardia spp. prevalence warrants further investigation and targeted interventions for canine gastrointestinal health.

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...
01:22Microbial Interactions: Parasitism
Parasitism is a form of microbial interaction in which parasitic microbes exploit a host organism for nutrients and shelter, often at the host's expense. Unlike mutualistic relationships, where both organisms benefit, parasitism benefits only the parasite and harms the host.Classification of ParasitesMicrobial parasites are broadly classified based on their location relative to the host.Ectoparasites remain on the host’s surface, such as the skin or outer tissues, drawing nutrients...
01:30Leishmaniasis
Leishmaniasis is a protozoal disease caused by species of the genus Leishmania and transmitted through the bite of infected female sandflies. The parasite exists in two principal morphological forms during its life cycle. A sandfly acquires intracellular amastigotes from an infected reservoir host, such as a dog. Within the sandfly, these forms differentiate into motile, flagellated promastigotes. During a subsequent blood meal, promastigotes are injected into the human host, where they...
01:28Toxoplasmosis
Toxoplasmosis, a zoonotic disease caused by the protozoan Toxoplasma gondii, poses significant public health challenges globally due to its high seroprevalence and varied clinical manifestations. As an obligate intracellular parasite, T. gondii can infect all warm-blooded vertebrates, but felids are its only definitive hosts, shedding unsporulated oocysts into the environment. Humans typically acquire the infection through ingestion of tissue cysts in undercooked meat or oocysts from...
01:12Giardiasis
Giardiasis is a globally prevalent intestinal infection caused by the protozoan parasite Giardia duodenalis (also known as G. lamblia or G. intestinalis). This flagellated protozoan is the most frequently identified intestinal parasite in the United States and worldwide. Transmission primarily occurs via the fecal-oral route, with infection arising from ingestion of water or food contaminated with cysts. Individuals in low-resource settings, international travelers, outdoor enthusiasts, daycare...
01:28Amebiasis
Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
