Sammanfattning : The crayfish plague refractory crayfish, Pacifastacus leniusculus, which can harbour the fungal parasite within melanotic sheath, are found to constitutively express the gene encoding for prophenoloxidase (proPO) after mimicking parasite attack. In contrast, the susceptible crayfish, Astacus astacus, responds to the parasite by increased levels of proPO transcript, particularly in the semigranular haemocytes. LÄS MER
Sammanfattning : This thesis focuses on the evolutionary interactions between birds and a parasite, the mosquito-borne Sindbis virus (Togaviridae, Alphavirus). In conclusion, the results show that the Sindbis virus is widespread among birds, and that the fitness of infected hosts may be reduced by the virus. LÄS MER

This parasite is not invasive and does not internalize into host cells but it rather attaches to the brush border surface of the small intestine disrupting the epithelial barrier. LÄS MER
4. Leishmaniasis in Sweden. Molecular, diagnostic and epidemiological studies of the parasite Leishmania in a non-endemic country
Sammanfattning : This doctoral thesis consists of four separate papers, in which we; investigate epidemiological and clinical aspects of leishmaniasis in Sweden in order to increase awareness of the disease, elucidate some aspects of the interaction of the parasite and the human immune system and validate serological tools as a complement for diagnosis of leishmaniasis..

From a quantitative point of view this statement is true: there were about ten thousand refugees in 1941, compared to almost two hundred thousand by the end of the war. LÄS MER
