Tick burden in neonatal roe deer (Capreolus capreolus): the role of age, weight, hind foot length, and vegetation and habitat on bed sites

This thesis deal with tick burden on roe deer (Capreolus capreolus) fawns, in relation to age, weight, hind foot length, and as well as to vegetation and habitat on bed sites. Roe deer fawns (N = 25) were captured from May 27 to June 27. Samples of Ticks were collected and tick burden were estimated. Of all sampled Ticks the nymphs and adults were Ixodes ricinus, while the larvae were not identified. 4.4 % of the sampled Ticks were larvae, 55.0 % nymphs, 26.8 % adult females, and 13.8 % adult males.

Prevalens och genetisk karaktärisering av afrikansk svinpestvirus i vektorer och tamsvin i Uganda

African swine fever, ASF, was first described 1921, in Kenya. The virus has thereafter spread through many African countries as well as in Europe, Asia, South- and Central America. The virus is spread via three different cycles, of which one is sylvatic and includes warthogs and soft Ticks. The other two are between domestic pigs and the one most common one is caused by humans, who not always realize the seriousness of precautions. The infection manifests as hemorrhagic fever, but can also be more or less unnoticed. The aim of this study was to use molecular tools to detect and partly genetically characterize ASFV both in soft Ticks and in serum from domestic pigs in Uganda. Comparing viruses detected in Ticks with those detected in domestic pigs I also wanted to investigate possible links between the sylvatic and domestic cycle.

Seroprevalence of Rift Valley fever in sheep and goats in Zambezia, Mozambique and preparations for a metagenomic study of arboviruses in ticks

The virus-mediated disease Rift Valley fever (RVF) was discovered during an outbreak in Kenya in the 1930s. Since then it has spread to most parts of Sub-Saharan Africa, and in the last decades several outbreaks have caused economic and health issues in Africa, Yemen and Saudi-Arabia. The disease mainly affects domestic livestock, causing abortions, but is also a zoonosis. To be able to control the spread of the disease it is important with surveillance for better knowledge about the distribution and virus circulation even in inter-epidemic/epizootic periods. The human population is growing, and people and their livestock constantly move closer to areas with wild animals which act as reservoirs for different viruses. Also, humans and their animals often get within reach for arthropod vectors, hosting or carrying viruses.

Emerging infectious diseases : a model of disease transmission dynamics at the wildlife-livestock interface in Uganda

Emerging infectious diseases are a recurring threat to both human and animal health. Understanding the multiple causes behind the emergence of new diseases is key to the prevention of new and potentially devastating outbreaks. The list of underlying causes is long, including a variety of anthropogenic, environmental, molecular and climatic changes that promote the emergence and spread of disease. Two of these factors are central to the emergence of new diseases and receive special attention in this study. The spread of disease from wildlife to livestock and diseases that spread from animals to humans (zoonoses) are of importance as they implicated in the majority of EID events.

Cross-sectional study of the prevalence of Babesia bigemina in Uganda : wildlife-livestock interface at and around LMNP

Ticks and the diseases they transmit are of major importance throughout the world. In Uganda, cattle are the most important livestock from an economic point of view. Livestock keepers fear bi-directional transmission of tick-borne pathogens between their livestock and wild animals. This cross-sectional study was conducted to establish and compare the sero-prevalence of the tick-borne pathogen Babesia bigemina among randomly selected Ankole Long-horned cattle and European crossbred cattle on 30 farms in Kiruhura district, in two sub-counties near Lake Mburo National Park in South-western Uganda. Half of the farms were situated in close proximity to the park and thereby housed cattle with more frequent wildlife-livestock interface (Sanga), whereas the other half had less frequent contact (Kikatsi).

Mastcellens funktion vid försvar mot infektioner

The complexity of the mast cell is becoming more prominent. From being the cell recognized just to contribute to allergic inflammation it is now also associated with wound healing, protection against tumor growth and in recognition and defense against a wide range of pathogens. The location of the mast cell in the barrier between the external and internal environment of the body enables the cell to quickly respond to invading bacteria, virus and parasites. Diarrhea due to Escherichia coli infection, listeriosis, toxoplasmosis, Newcastle disease and bovine respiratory syncytial virus are examples of mast cell activating diseases that can affect animals in, as well as outside, the agricultural sector. Additionally, Ticks and tick-borne diseases are of concern.

Babesios : en fallbeskrivning samt diskussion av fästingburna sjukdomar hos nöt i Sverige

Many farms in the counties in the south of Sweden have difficulties with diseases spread by Ticks; mainly babesiosis and tick-borne fever (TBF) but there are indications that borreliosis ought to be included. All of the tick-borne diseases radically decrease farm profit if the herd is affected. The production of the vaccine used against babesiosis since the 1920´s, will be discontinued in the near future and in addition to economical reasons it is therefore important to learn more about the diseases above. During the summer and fall of 2002 and 2003, a farm in the island of Gotland was burdened with unusually many cases of bovine babesiosis. In total 43 animals fell ill and one died.

Teaching Maths in Primary School - Something more than adding up and ticks and crosses?

Syftet med det här utvecklingsarbetet är att ge ett förslag på hur man som lärare kan engagera och motivera fler elever till att sträva efter att nå målen i ämnena svenska och historia på högstadiet. Utifrån tidigare forskning, olika teoretiker, läroplanen för grundskola 2011 och de nya kursplanerna för svenska och historia utformas ett utvecklingsarbete som utgår från ett tematiskt arbetssätt där skönlitteratur har en central roll i temat och där läromedel ersätts med olika varierade moment som film, museum besök, gästföreläsare etc. Temat kallas revolutionernas tidevarv och behandlar 1700-1800 talet med fokus på Franska revolutionen, ideologier och de samhällströmningar som följer av detta. Eleverna jobbar både i grupp och med tre stycken individuella uppgifter. Temaarbetet sträcker sig över sex veckor och totalt 30 timmar.

Prevalens av Sarcoptes scabiei hos thailändska gatuhundar :

The aim of present study was to evaluate the prevalences of Sarcoptes scabiei in Thai stray dogs. The study was performed in Pattaya, Thailand, and included 62 stray dogs, all cross-breeds. Degree and type of skin lesions, and presence of macroscopic ectoparasites were recorded for each individual. Blood samples were collected to determine the seroprevalences of IgG-antibodies against S. scabiei with ELISA.

Cross-sectional study of bovine anaplamosis in South-western Uganda : the impact of wildlife-livestock interface

The tick-borne disease bovine anaplasmosis is primarily caused by Anaplasma marginale. A variety of wild animals act as reservoirs for A. marginale, but the understanding of their role in the epidemiology of A. marginale is yet poor. This cross-sectional study was conducted to establish if proximity of wildlife affect the prevalence of bovine anaplasmosis in cattle.

Retorik på scen - En studie om scenisk kommunikation

I have made an inquiry about stage communication, small talk and on-stage rhetoric. The essay is divided into different parts. There is a background part that gives a short overview about other research and literature that has been made on the subject. A background has been put together to help you as a reader to understand the complex science can be. Here you will find work written by Dorothy Irving and Åke Lundberg among others.
