1. MHC polymorphism and host-pathogen interactions: The case of Borrelia in its reservoir host, the bank vole Myodes glareolus
Sammanfattning : The major histocompatibility complex (MHC) class IIB genes exhibit extensive allelic polymorphism, most likely maintained by pathogen-mediated balancing selection (PMBS). PMBS may operate in the form of heterozygote advantage (HA), and/or through the interaction of pathogens and specific MHC alleles via fluctuating selection (FS) or negative frequency-dependent selection (NFDS).

2. Emerging tick-borne pathogens: on the ecology of multiple infections in ticks and reservoir hosts
Sammanfattning : Most animals will encounter several more or less severe infectious diseases during their lifetime, and simultaneous infections with more than one pathogen, or several different strains of the same pathogen, are common in natural populations. Ticks transmit a wide variety of different pathogens and can also be simultaneously infected with more than one pathogen. LÄS MER
Sammanfattning : The bank vole (Microtus arvalis) develops glucose intolerance both when kept in captivity and in the wild state. Glucose intolerant bank voles kept in captivity exhibited polydipsia, polyuria, hyperglycemia, hyperinsulinemia, islet autoantibodies and a markedly changed islet structure resembling so–called hydropic degeneration.

Sammanfattning : Land-use change is causing extinction of species globally, while also increasing the risk of disease exposure to humans through augmented interactions with wildlife, when humans live and work in manipulated ecosystems or when animals seek shelter/refuge in man-made infrastructure. Forestry is one such activity, which is continually altering forest structure worldwide, causing habitat loss for many specialized forest species. LÄS MER
Sammanfattning : Hantaviruses are the causative agents of hemorrhagic fever with renal syndrome (HFRS) in Eurasia, and of hantavirus cardiopulmonary syndrome (HCPS) in the Americas. Transmission to humans usually occurs by inhalation of aerosolized virus-contaminated rodent excreta. LÄS MER
