Summary: Eperythrozoonosis in pigs is the most frequent latent
infection caused by the rickettisia Eperythrozoon suis. It is a
conditionally infectious disease triggered by such stress factors as birth,
weaning, transport, inadequate zoohigienic and nutritional conditions, as
well as by the development of some other infectious diseases, especially
these of the respiratory and digestive tracts. Depending on the age
categories, eperythrozoonosis in pigs manifests itself by various symptoms,
of which, in the acute phase of the disease, the most pronounced ones are
the increased temperature, anemia, and generalized icterus. The disease was
diagnosed for the first time in the US (Kinsley, 1932; Doyle, 1932;
Splitter and Williamson, 1950) and then in other parts of the world. In
Croatia it was first found in 1986 in Sisak (Modrić et al., Vet. glasnik
41, 233, 1987).
Research goals: Through publications and lectures about porcine
eperythrozoonosis we should inform veterinarians and swine breeders with
the disease. Besides, in experimentally infected splenectomized or
nonsplenectomized pigs with E. suis we have studied: clinical symptoms,
hematological, biochemical and immunological parameters as well as
pathomorphological and histopathological alterations. Futhermore, in the
latent phase of the disease we have evaluated hygiene and quality of swine
meat, developed serological diagnosis of the distribution of the disease
among our swine producers, and started with prophylaxis. This research will
add to our understanding of the disease in Croatia and will contribute to
implement prophylactic measures in swine production with diagnosed
eperythrozoonosis in order to decrease economic losses. Other information about the project.
