In the parasitology department of our Parasitology Laboratory, the diagnosis of the parasitic diseases of domestic animals are being made. By using accurate, cost-effective and fast techniques, veterinary clinicians and animal owners are made to gain favor to increase the health quality.
Some of the departmental services
1-In the stool;
-Qualitative and Quantitative analyses with the Concentration with Centrifugal Flotation
-Diagnosis with Antigen-capture ELISA (such as Cryptosporidium and Giardia)
-Direct fecal smears
2-In the serum;
-Dirofilaria Antigen test
-Feline Toxoplasma gondii IgG and IgM
– Leishmaniasis antibody
– Microfilarial Fitration Technique (MFT) in the Microfilaria diagnosis
– Skin parasites
The samples that can be sent for the diagnosis purpose: Stool, Blood, Urine, Tracheal lavage, duedonal aspirates, skin scrapings and necropsy samples.
Frequently diagnosed parasites in our laboratory
Toxora canis: It is a nematode living in the small intestines of the carnivore animals such as, especially dogs, fox, wolf and jackal. The eggs of the ovipar parasite are close to spherical shape, and sometimes oval. Since this parasite causes visceral larva migrans in humans, it is closely related with the human health as well as its importance in the veterinary medicine. Today, although a number of helminthes are known to cause the visceral larva migrans in various hosts, primarily parasite is T. canis is responsible for this syndrome.
Toxoplasma gondii: It is a unicellular species included in the Toxoplasma genus. Toxoplasmosis is caused by the parasitic protozoa Toxoplasma gondii. Cats are infected with this disease by ingestion of the Toxoplasma infected mice. Then, the factor starts to rapidly reproduce in the intestine of the cat and the cat excretes the oocysts in its stool. Infection also spreads to the human or other animals that ingest the Toxoplasmic organisms.
Toxoplasma infection might not always show a symptom. The major symptoms are anorexia, lethargy, weight loss, fever and neurological disorders. Since the disease mainly progresses subclinically and asymptomatically, the clinical diagnosis is difficult and the direct diagnosis of the factor is not practical. Thus, various easy, rapid and practical serological methods are generally used for the diagnosis. Indirect hemagglutination test (IHA), indirect immunofluorescence antibody test (IFAT), direct agglutination test (DAT), latex agglutination test (LAT) and enzyme-linked immunosorbent assay (ELISA) are also used for the diagnosis. In our laboratory, by using IFAT, which is the technique with the highest specificity and sensitivity, IgG and IgM antibodies are analyzed in cats.
Isospora sp.: The factor which commonly cause infection and is diagnosed in dogs in Isospora canis. Although the disease can be seen in the puppies in developmental stage, it can be seen in all ages. The factors can be found in the small intestine by showing no clinical signs. Since those dogs can be carrier, parasitary stool examination is beneficial for the early diagnosis. The factor which cause infection in cats and most commonly determined is Isospora felis. Although the disease can be seen in the puppies in developmental stage, it can be seen in all ages.
The specific symptom of the disease, which is structured by gaining pathogenicity of Isospora after reproduction, is diarrhea. Generally, soft and aqueous stool is seen. However, sometimes stool with mucus or bloody stool can also be seen. The signs that can be seen when the infection is severe are weakness, anorexia, vomiting, weight loss and increase in the body temperature.
The untreated, progressed cases can result with death. The death cause is the weakening of the body resistance, excess fluid loss or increase of the severity of the case due to development of another infection.
Taenia sp.: Tenia is an animal species from the invertebrates class, belonging to cestode family of the flat worms order, living in the small intestine, spreading from cattle meat and whose most common species in Turkey is Taenia saginata. It causes infection in the small intestine. It can cause stomach ache, problems in intestinal excretion and weight loss. The most common symptom is the salivation during the sleep since their movement in the esophagus stimulates the salivary glands.
