    Brucellosis

    Brucellosis is a long known zoonotic disease in humans and animals which is caused by gram-negative bacteria of the Brucella genus. Brucella is classified as risk group III by the WHO. Various species of Brucella were isolated from bovines, with Brucella abortus being identified as the most frequent cause of bovine brucellosis. If cattle are held in direct vicinity of small ruminants such as sheep or goat, infections with Brucella melitensis may also occur. Dogs and cats can also be vectors of Brucella. Bovine brucellosis should generally be considered as a herd problem. Transmission of the pathogen can be oral, but also venereal, congenital or perinatal.

    Brucellosis

    Brucellosis is a zoonotic disease which is caused by gram-negative bacteria from the Brucella genus. Brucella is classified as risk group III by the WHO. The species Brucella abortus and Brucella melitensis were identified in camels. The disease was first described in 1931. Even though clinical symptoms are generally mild in camels, Brucella can be transmitted to humans via fresh milk or raw meat and turn into a serious health problem in the affected regions.

    MERS coronavirus

    Middle East respiratory syndrome (MERS) is caused by a previously unknown coronavirus (MERS-CoV). So far, all human MERS-CoV infections have originated in the Middle East. About 40 % of known cases were fatal. The incubation time ranges from less than a week in the majority of cases to up to 12 days in individual cases. Transmission between humans takes place via aerosols and smear infections. Respiratory secretions of the upper respiratory tract of infected persons play a particularly important role as they can be passed on by sneezing, coughing, and via contaminated hands.

    Toxoplasmosis

    The pathogen of toxoplasmosis is the sporozoon Toxoplasma gondii. The only final hosts are the domestic cat and other felidae, in which the parasite lives in the intestine and forms oocysts in the sexual developmental stage. In general, infection occurs perorally by ingestion of water or food contaminated with oocysts (through the faeces of infected cats) or from meat products (the raw flesh of infected animals contains cysts with viable trophozoites).

    Anaplasmosis

    Anaplasma (A.) phagocytophilum is the causative agent of anaplasmosis, a bacterial disease which is transmitted through bites from ticks of the genus Ixodes. A. phagocytophilum is a gram-negative, obligate intra-cellular bacterium which attacks mostly neutrophilic granulocytes, but also, in rare cases, eosinophilic granulocytes. Anaplasmosis occurs worldwide, its prevalence depending on the distribution area of the transmitting vectors.

    Lyme borreliosis

    Borrelia is the causative agent of Lyme borreliosis, a bacterial disease which is transmitted through bites from ticks of the genus Ixodes. The gram-negative bacteria are collectively referred to as Borrelia burgdorferi sensu lato. In this group, the genospecies Borrelia burgdorferi sensu stricto, Borrelia garinii and Borrelia afzelii are pathogenic for dogs and horses. Whereas in the U.S. only B. burgdorferi sensu stricto is relevant, more than 80 % of Borrelia in European ticks belong to the pathogenic genospecies B. garinii or B. afzelii. Dogs and horses have a significantly increased risk of infection because of their higher frequency of contact with ticks. Most of the infections, however, proceed asymptomatically. Infection does not confer strong immunity. Reinfection is therefore possible. Antibodies against B. burgdorferi can be found in the serum of specifically infected or vaccinated animals. An infection with B. burgdorferi is associated with a variety of clinical symptoms, which generally occur weeks or months after infection.

    Ehrlichiosis

    Ehrlichiosis is a disease which is transmitted to animals and humans by ticks. In canine ehrlichiosis, especially the pathogen Ehrlichia (E.) canis plays a role, which is mainly transmitted by the brown dog tick (Rhipicephalus sanguineus) and may lead to canine monocytic ehrlichiosis (CME). E. canis is a gram-negative, obligatory intracellular bacterium which mainly affects the mononuclear cells of the blood. CME occurs in tropical and moderate climates worldwide. The geographical distribution of E. canis increases with the further distribution of the vector tick which is accelerating due to climate change.

    Leishmaniasis

    Leishmaniasis is a zoonotic infection that is caused by protozoa of the Leishmania genus. Leishmania infantum, Leishmania chagasi and Leishmania donovani, which belong to the Leishmania donovani complex, are of particular importance. These monocellular parasites are transmitted to humans or animals via the bite of female sandflies of the genera Phlebotomus (Africa, Asia, Europe) or Lutzomyia (Central and South America). Dogs are considered as the most important reservoir. Due to the zoonotic potential, infected dogs are a major problem in veterinary and human medicine. It is assumed that 50 % to 80 % of dogs in endemic areas are infected with Leishmania. However, Leishmania infection is not synonymous with canine leishmaniasis. Less than 10 % of infected dogs show clinical symptoms. Certain dog breeds and the age of the dog are associated with a predisposition for the development of leishmaniasis. The immune response of the dog is also crucial for manifestation.

    Tick-Borne Profile

    The distribution area of ticks is continuously increasing due to global warming. Consequently, tick‑borne diseases such as anaplasmosis, borreliosis and tick‑borne encephalitis (TBE) occur more frequently in dogs and horses as well.

    Toxoplasmosis

    Toxoplasmosis is a zoonosis which occurs worldwide and is caused by the sporozoon Toxoplasma gondii. All warm-blooded animals can become infected with Toxoplasma (T.) gondii. The asexual reproduction of T. gondii can take place in the most diverse tissues of the warm-blooded intermediate hosts. The only final hosts are cats or other felidae, in whose intestine the sexual reproduction takes place. This leads to the formation of oocysts which are secreted into the environment with the cat’s faeces.

    Autoantibodies against cell nuclei

    The detection of anti‑nuclear antibodies (ANA) is an important diagnostic indicator in many autoimmune diseases. ANA are directed against various cell nuclear components. These encompass nucleic acids, cell nuclear proteins and ribonucleoproteins.

    West Nile virus

    West Nile virus (WNV) is an enveloped single-stranded RNA virus of the Flaviviridae family. It is transmitted by a variety of mosquitoes and has so far been discovered in more than 40 different mosquito species and in several tick species. Birds represent the vertebrate reservoir. Acting as incidental hosts, mammals can also become infected when bitten by an infected mosquito.

    Mouse monitoring

    The microbiological status of laboratory animals is not only decisive for their own well-being but it also affects the validity and reproducibility of research data. For this reason regular health monitoring in experimental animals is of major importance. For the monitoring of the microbiological status of laboratory animals the guidelines of the Federation of European Laboratory Animal Science Associations (FELASA), for instance, recommend regular tests for various bacteria, viruses and parasites. Certain parameters should be investigated every three or twelve months at random.
