Test Instruction

Further information

Anaplasma and ehrlichia are vector-borne (ticks), intracellular bacteria. Dirofilaria immitis and the dog's leishmaniasis are transmitted by blood-sucking mosquitoes.  


D. immitis (CHW): Infection with D. immitis can lead to a serious and even fatal disease in dogs. Adult heartworms can survive in dogs for 5-7 years. The antigen test is used to detect circulating D. immitis antigens in the blood; adult female heartworms are detected.


Anaplasmosis: In Europe, Anaplasma phagocytophilum is found in domestic dogs. The antibodies are detected using A. phagocytophilum antigens.


Ehrlichiosis: Dogs infected with Ehrlichia develop canine monocytic ehrlichiosis. The occurrence of infection is related to the spread of the vector R. sanguineus. The antibodies are detected using E. canis antigens.

Leismaniasis: In Europe, dog leishmaniasis is caused by the protozoon Leishmania infantum. The antibodies are detected by a specific antigen and can be used in diseased dogs about six to eight weeks after initial infection.


Remarks for the test result interpretation: Negative test results in antibody tests: they do not rule out an infection, as seronegative results can occur at any stage of infection. Positive test result for antibody tests: In the endemic area, positive antibody results can be due to a previous infection.

CanVecto 4 – rapid test systems to detect dog diseases

CanVecto 4 is a rapid test system developed by Fassisi. Within a very short time, this test system detects antibodies of very common dog diseases in order to react quickly with an optimal treatment plan. The rapid test CanVecto 4 reliably shows a possible infection with the following bacteria: Dirofilaria immitis, Anaplasma Phagocytophilum, Ehrlichia canis and Leishmania.


Fassisi rapid test systems are suited for the use in a veterinary practice or clinic as well as for an on-site use at the patient’s home. Within a few minutes, the results of the taken blood or plasma samples are available.

There is, as with any other medical test systems, the possibility of a false-negative result, since in every stage of an infection seronegative results cannot be excluded. Also, false-positive results are possible, since antibodies from former and overcome diseases can are indicated when in the taken sample. We recommend control tests, to exclude false-negative or false-positive results.


Our Fassisi test systems should be stored between +2 °C and +30 °C, otherwise the system’s functionality can be impaired.



Further information to CanVecto 4

Leishmaniasis and Dirofilaria immitis, also called dog heartworm, are both transmitted by blood-sucking mosquitoes and are foremostly endemic in warm temperate, tropical and subtropical climate zones.

Dirofilaria immitis: The heartworm can survive around 5 to 7 years in a dog and is highly pathogenic. An infestation with a heartworm potentially entails sever to lethal conditions. The Fassisi antigen-test serves as evidence to detect circulating antigens of Dirofilaria immitis antigens in a dog’s blood which are traced back to adult female heartworms.


Leishmaniasis: Leishmaniasis or more correctly the disease-causing protozoon Leishmania infantum is foremostly transferred by sandflies. Tricky about this disease is, that the incubation time normally is about two months, but an outbreak can also occur several years after the infection. A proof of antigens can be conducted not earlier than 6 weeks after the infection.


Pathogens of Anaplasmosis and Ehrlichiosis are transmitted through ticks, they therefore are vector-based, intracellular dog diseases. Often infected dogs show no or only mild symptoms. In some cases however, both diseases have severe or even lethal complications.

Anaplasmosis:In Europe the bacteria Anaplasma phagocytophilum are found in pet dogs. Antibodies to this bacterium are detected by Fassisi test systems using corresponding antigens.


Ehrlichiosis: dogs infected with Ehrlichias develop a canine monocytic Ehrlichiosis. The occurrence of Ehrlichia infections correlates with the spread of its vector, the brown dog tick, found in tropical, suptropical zones and the Mediterranean. Antibodies are detected by using E-Canis-antigens in our rapid test systems.
