Mikroorganismer och antibiotikaresistens vid otitis externa hos hund. :
Canine otitis externa is a common reason for a visit to the vet. Predisposing
factors often complicate treatment and may result in a chronic disease
progression. All otic preparation for topical use in Fass Vet contain antibiotics,
corticosteroids and a fungicide. Sixty cerumen samples from dogs with external
otitis, sent to the Department of Bacteriology at SVA, were categorised according
to their profile of isolated microorganisms. Staphylococcus intermedius alone or
together with Malassezia pachydermatis were the most common organisms found.
Fifteen percent of the samples contained M.
Jämförelse mellan subjektiv och objektiv bedömning av hälta hos häst på böjt spår.
The female dog has a unique reproductive endocrinology, with high levels of progesterone throughout the 70-day long luteal phase. In this project, markers of glucose metabolism were studied and compared from the aspects of breed group and time in oestral cycle. The parameters studied were: glucose, insulin, progesterone, fructosamine and the newly introduced analysis of HbA1c. Hba1c was also further evaluated and discussed as a diagnostic tool in canine medicine.No differences in terms of glucose markers were found between a group of purebreed dogs of various breeds compared to a group of dogs with high risk of dioestrus diabetes, namely the Norwegian and Swedish elkhounds.No differences were found between the two sample occasions, anoestrus and dioestrus, concluding that there is no need for relating test results to the time of the oestrous cycle in middle-aged intact female dogs.There were statistically significant higher values of all glucose markers in diabetic dogs than in non-diabetic dogs. When it came to HbA1c, however, there was a larger overlap between the two groups, compared to fructosamine.

Use of feline TK1 as a biomarker in disease monitoring
Serum thymidine kinase 1 (TK1) activity is used as a tumor marker in disease monitoring in veterinary and human medicine. TK1, an intracellular enzyme, is involved in a salvage pathway of DNA precursor synthesis.
TK1 is used in DNA precursor production by catalyzing the transfer of the gamma-phosphate-group from a phosphate-donor to the 5?- hydroxyl-group of thymidine forming thymidine-monophosphate. Nucleoside monophosphosphates are finally converted into thymidine-triphosphates. TK1 activity significantly rises in the G1 and the S phase of the cell cycle.

Effekter av skendräktighet och kastration på tikens beteende
Pseudopregnancy is a condition that is estimated to affect 40 % of all female dogs. Common symptoms are decreased activity level, weight gain, mammary enlargement, milk production, nesting behavior, anorexia and maternal behavior. The symptoms are displayed during metoestrus. Prolactin is one of the causes behind pseudopregnancy, but the full process is not yet known. Due to the fact that the condition affects that many bitches and often is recurrent, it is relevant to examine how the condition affects the bitch?s behavior and performance.
Aortic Body Tumors in Dogs
The purpose of this essay was to review the literature and describe the patophysiology, diagnosis, microscopic and macroscopic appearance of aortic body tumors in dogs. The tumors originate from the chemoreceptor organs situated at the base of the heart. The chemoreceptor organs are neuroendocrine cells responsible for surveillance of changes in e.g. the blood pH. Aortic body tumors are rare and represent 7 % of the total cases of primary cardiac tumors in canines.
Livslängden hos kyllagrade spermier vid artificiell insemination hos häst - kan den förlängas?
Över 90 % av betäckningarna inom Avelsföreningen för svenska varmblodiga hästen (ASVH) skedde med artificiell insemination (AI) år 2011. AI har många fördelar i avelsarbetet då hingsten inte behöver vara på plats när stoet brunstar, möjligheten att välja bland både nationella och internationella hingstar ger en stor valmöjlighet för stoägaren. I Sverige samlas sperma från hingstarna normalt sett tre gånger i veckan genom upphopp på en fantomhäst där ejakulatet samlas i en artificiell vagina. Trots mycket forskning är det fortfarande ca 20 % av hingstarna som lämnar spermier som inte lämpar sig för frysning.
Innan nedkylning centrifugeras seminalplasman bort eller späds ut för att reducera inverkan på spermierna. Seminalplasman har positiv inverkan på spermierna vid naturlig betäckning men kan ha negativ inverkan på spermierna under lagring.
Jämförande studie av normal ERG-svar hos tre olika hundraser :
The purpose of this study was to compare normal electroretinographies (ERGs) from three different canine breeds in order to evaluate if there were any marked similarities or differences between these breeds as to ERG responses. It is known that healthy dogs from different breeds but also dogs within the same breed but in different age categories may have different appearances of their ERG responses. This may be a problem when evaluating if an ERG is normal or not from a dog within a breed not previously examined. Because of this it is important to obtain normal values for each breed and age group in order to be able to use these for later comparisons of ERGs obtained from individuals affected with various retinal diseases.
In this study we have chosen to examine dogs within the three breeds: Labrador Retriever (LR), English Springer Spaniel (ESS) and Chinese Crested Dog (CCD). All of these breeds may be affected with hereditary retinal diseases such as Progressive Retinal Atrophy (PRA).
It is possible that ERG-responses vary due to a number of different factors.
Kons fertilitet : kostnader och åtgärder
To get a good economy on the dairy farms the fertility control of heifers and cows is a crucial
factor. It is also important to know which key parameters that should be tracked.
In this work well established routines for heat detection have to be applied. When the dairy
farmers use technical aid in estrus control it is important not to forget that technical aids can
not replace the human eye. Approximately 50 % of all opportunities to inseminate are missed
because clear signs of estrus have not been displayed and/or recorded.
The cattle fertility has been declining over recent years. During the same time the cow?s
proceeds have increased, consequently applying a higher pressure on the cow and the
manager.
Progesteronrelaterad diabetes mellitus hos älghund :
Diabetes mellitus (DM) is a relatively common endocrine disease in dogs and is more common in certain breeds than others, e.g. Nordic spitz breeds. Within the Swedish and Norwegian Elkhound population, female dogs are almost exclusively affected. The hypothesis in this study is that Swedish- and Norwegian Elkhounds develop DM during the progesterone phase of estrous (diestrous or pregnancy).
Medical records from 51 female dogs of the breeds Swedish and Norwegian Elkhound were studied.
Prevalence of selected infectious diseases in Samoan dogs
SCA is the largest private owned forest owner in Sweden, with an ownership of 2 million hectares of productive forestland. To manage the planning of such large areas and to fit the traditional organization structure of a Swedish forest company, the planning approach is subdivided into three stages; strategic, tactical and operational.
The strategic part, based on a statistic sample of stands, returns a harvest level estimate which should then be implemented at actual sites in the tactical part. This procedure can lead to incompatible solutions as the strategic solution is not necessarily possible to translate into actual sites in the tactical plan. The geographic aspect is important in tactical planning due to the large costs for moving equipment and maintenance of a large number of forest roads.
Lymfocytär tyroidit hos hund (clt) : genetik, patogenes, histologi
Hypotyreoidism är en vanlig endokrin sjukdom hos hundar. Den orsakar nedsatt livskvalitet i form av utbredda symptom från flera olika organsystem och sjukdomen kräver livslång medicinering. En orsak till hypotyreoidism är Canine Lymphocytic Thyroiditis (CLT), en autoimmun sjukdom som står för ett stort antal av sjukdomsfallen hos hund. Mycket talar för att utvecklandet av sjukdomen har en ärftlighetskomponent eftersom den uppträder i mycket hög frekvens inom vissa raser medan det är en tämligen ovanlig åkomma inom andra raser. Studier av hundpopulationer har visat på en genetisk koppling mellan CLT och gener för Dog Leukocyte Antigen II (DLA II) hos vissa raser.

Jämförelse mellan hundskolans och Svenska Brukshundklubbens kursdeltagare i Skaraborg :
The aim with the present study was to investigate whether there is a difference between the course participants who find their way to the dog-school respective the Swedish Working Dog Association. The study have focused on four issues; why the course participants have chosen the dog-school respectively the Swedish Working Dog Association, why the participants bought their dog, if the participants are satisfied with their dogs and if it is more likely that they turn to the dog-school?s than to the Swedish Working Dog Association with their first dog?
Course participants from two dog-schools and from two of the local clubs belonging to the Swedish Working Dog Association in Skaraborg, Sweden, answered a questionnaire. In total 85 answers were collected, including 60 from the course participants from Swedish Working Dog Associations and 25 from the dog school?s course.
