Utveckling och applicering av en aviditets-ELISA för bovint respiratoriskt syncytialt virus :
Bovine Respiratory Syncytial Virus (BRSV) is a common cause of respiratory disease among young cattle. The virus causes severe losses; the herd mortality rate can sometimes be as high as 20 %. In this study the avidity (i.e the antigen binding force) of BRSV specific antibodies was measured to see if there was a difference between antibodies produced during an acute phase of infection and antibodies produced by earlier infected animals.
A commercially available ELISA-testkit against BRSV-specific antibodies was used and an incubation step with 6M urea was added. The effect of the urea is that it breaks the weak bonds between antibodies and antigen while the stronger bonds remain intact.
Four different groups of animals were included in this study; seven calves that were naturally infected, three acutely infected calves with known time of infection, five cows that were seropositive during several years and four experimentally infected calves that had been a part of a vaccine trial.
The results of this study showed that antibodies produced during the acute phase of an infection had a low avidity and that the avidity increased with time after infection.
Begomovirus prevalence and diversity in the TYLCV resistant tomato cultivar Shanty in Nicaragua
Every year begomovirus infections cause severe constraints to the tomato production in Nicaragua. Extensive yield losses are followed by large economical losses, both for the country and the single farmer. During recent years the use of begomovirus resistant or tolerant tomato cultivars has increased in Nicaragua as an effort to improve yields. Still, begomovirus infection is a large threat to the tomato production. Therefore, ongoing work in Nicaragua is focusing on finding new, better, begomovirus tolerant or resistant tomato cultivars.
Patientrelaterade riskfaktorer för postoperativ sårinfektion efter Coronary Artery Bypass Graft - CABG
Introduction Postoperative wound infections leads to increased patient suffering and cost society money because it leads to longer hospital stays. Previous research shows that patient related risk factors such as smoking, diabetes, Chronic Obstructive Pulmonary Disease (COPD), advanced age (>65 years) a low preoperative hemoglobin level (<140g/L) and a high BMI (> 30) increases the risk of suffering a postoperative wound infection. Aim To investigate whether patients that underwent surgery with Coronary artery Bypass Graft (CABG) in a university hospital in central Sweden in 2013 and had any of these risk factors more often suffer from post-operative wound infection.MethodThe study has a descriptive design and is based on an ongoing infection registration area of operations. The study included 148 patients out of 255 (58%) undergoing CABG in 2013. Possible risk factors were collected through medical record review.Results There was no significant correlation between surgical wound infection and patient-related risk factors such as smoking (not quit smoking four weeks before surgery), diabetes, COPD, advanced age (>65 years), low preoperative hemoglobin (<140g/L) or a high BMI (>30) and suffered a postoperative wound infection.Conclusion More research and a larger sample is needed in the field to produce a reliable result could be presented..
A literature study on Methicillin-resistant Staphylococcus pseudintermedius (MRSP) : classification, resistance mechanisms, risk factors and clonal distribution
The increased frequency of reported Methicillin-resistant Staphylococcus pseudintermedius (MRSP) is of great concern to small animal healthcare due to limited options of antimicrobial therapy. The aim of this literature study is to investigate 1) characteristics and classification of
S. pseudintermedius, 2) resistance mechanisms and emergence of MRSP, 3) risk factors for selection of MRSP, and 4) clonal distribution around the world. S. pseudintermedius is a skin and mucosal commensal in healthy dogs and cats, but can cause infections, including pyoderma.
Beta-lactam antibiotics inhibit bacterial growth by binding to the penicillin binding protein (PBP), a vital enzyme in the synthesis of the bacterial cell wall.
Användandet av samlingsprover för att bestämma besättningsstatus för smitta med Dictyocaulus viviparus hos förstagångsbetande nötkreatur :
Infection with the bovine lungworm - Dictyocaulus viviparus - is occasionally a problem in Swedish cattle herds. The infection could act in synergism with other infections such as Corona virus to create a poorer welfare and productivity in cattle. Studies have shown that a diagnosis can be made with both the Baermann method and with an ELISA. In Norway diagnosis of BVDV on a herd level is attained through pooled serum samples. The question was raised whether pooled serum samples could be used in a similar fashion to attain status on a herd level for lungworm.
Hållbarhetsstrategier: Är det ett hinder att vara mindre? ? En studie kring motiv bakom implementering av hållbarhetsstrategier i mindre svenska företag inom hudvårdsbranschen
Problem: Small companies dominate the skin care industry, and they also face moredifficulties, constraints and resistance in strategy implementation and sustainabilitywork than other operators. Still, the trend of sustainability strategies increasesignificantly precisely in this industry.Purpose: The purpose of the study is to contribute knowledge to the field ofsustainability strategies and motives for the implementation of them in smallercompanies who engage with skin care, in Sweden.Framing of a question: Why do some smaller Swedish companies in the skin careindustry choose to implement sustainability strategies in their business?Literature: The literature functions as a framework for the study and is considered toidentify the possible reasons why small companies choose to implement sustainabilitystrategies or not. The literature is collected before the empirical data.Method: This paper is constructed by a qualitative method approach. The empiricaldata were collected through interviews, by telephone, personal meetings and email,which were then transcribed and the interpreted by a model, which the authors havecreated.Conclusion: Smaller companies are often met by larger resistance and an until up tothe present slowly emerging industry with vague rules and controls as well as ancomparative knowledge of what is good and what is not.
Omvårdnad av nyförlöst kvinna som har infektion av Streptococcus pyogenes : En litteraturstudie
Bakground: Puerperal fever caused by group A Streptococcus is in a global context seen as a common cause of death in childbirth.Aim: To examine the consequences of group A streptococcus infections in women postpartum and to see what a nurse can do to stop the infection with adequate nursing interventions.Method: This is a review built on 15 articles. These articles were read in full and audited with a suitable template.Result: Women postpartum has 20 times higher risk to get group A stretococcus infection as compared to non pregnant. The consequences of Group A Streptococcus infection can lead to high fever, abscesses around the uterus, sepsis, acute respiratory distress syndrome (ARDS), hysterectomy and death. Patients who share room with infected patients carries an increased risk to be infected. Curtains between patient beds can be colonized by Group A Streptococcus.
Effekter av sedering med dexmedetomidin och butorfanol på hudreaktivitet vid intradermaltest på friska hundar
The effects of dexmedetomidine and butorphanol sedation on skin reactivity during intradermal testing in healthy dogs were evaluated. The effects of dexmedetomidine and butorphanol were compared to medetomidine, a sedative agent having scientific proof of not interfering with skin test reactivity, in a randomised, double blind, cross over study performed on 8 adult dogs. The dogs were sedated with medetomidine (Domitor vet.®, 0,01 ml kg-1) intravenously, or dexmedetomidine and butorphanol intramuscularly (Dexdomitor vet.®, 0,01 ml kg-1; Dolorex vet., 0,01 ml kg-1) after which they received intradermal injections of positive control solutions (histamine 0,1 mg ml-1, 0,05 mg ml-1, 0,025 mg ml-1), a negative control solution (0,9 % NaCl) and allergen extract (Dermatophagoides farinae, Cladosporium and Artemisia vulgaris). After a wash out period the trial was repeated with a reversed sedation protocol.Skin reactivity (wheal size, induration and erythema) and quality of sedation (immobilization, response to stimuli and injections as well as over all working conditions) were evaluated. The combination of dexmedetomidine and butorphanol provided reliable, good sedation and analgesia without adverse effects.
Bovin tuberkulos : smittvägar mellan människa och nötkreatur på den östafrikanska landsbygden
Tuberculosis is one of many infectious diseases in the world and is responsible for a large number of human deaths each year. The cause is Mycobacterium ssp included in the tuberculosis-complex, there among Mycobacterium bovis and Mycobacterium tuberculosis. Infection with M. bovis causes bovine tuberculosis in cattle which in 90 % has a pulmonary location. Humans are infected mainly by milk from infected cows but also by close contact with coughing animals or by eating raw meat.

Hästens hudproblem : en retrospektiv fallstudie
SUMMARYThis work consists of a review of the medical records of 142 horses that visited the Equine dermatology clinic, at the University Animal Hospital, UDS, at Ultuna, Uppsala, Sweden, between January 2007 and June 2010. The study answers certain main questions like clinical signs responsible for the visit, the most common diagnoses, their diagnostic procedures, treatment modalities and finally, the outcome of treatment.Among 50 diagnoses, four were predominant followed by additional 46 diagnoses, each presenting by few or, in many cases, only one horse. The most common dermatological problem diagnosed was Equine Sarcoid representing 18,3 % of the cases (26/142), which probably reflects the initiation of a Sarcoid treatment-trial in 2007, that resulted in an accumulation of sarcoid horses in the clinic .The second most common diagnosis was Atopy 12 % (17/142) followed by Allergy with skin affection 9,2 % (13/142) and Acute superficial pyodermia 4,9 % (7/142). If the horses were divided into diagnostic groups, the majority (34,5 %) belonged to HA5 group, (Immunological skin diseases), followed by group HA4, (Infectious and inflammatory conditions of the skin) (22,5 %) and HA6, (Neoplasia) (21,8 %). Traumatic skin injuries represented only 2,1 % of the cases, compared to 80 % of horses in the Agria insurance statistics for veterinary care.The most common clinical sign and reasons for veterinary consultation was pruritus (35,9 %), suspected sarcoids (17,6 %), alopecia (12,7 %), nodules (12 %), seborrea, scaling and crusts (9,2 %) and excoriations (5,6 %), respectively, followed by a scattered number of more uncommon symtoms.The diagnostic methods most frequently applied were cytology and biopsy, used in 41,5 % and 36,6 % of the cases, respectively.

Orsaker till låg följsamhet till handhygienföreskrifter : En litteraturöversikt
Background: Hand hygiene is the simplest and most fundamental means to prevent care related infections. It is of great importance that the guideline of hand hygiene is followed for the patient?s sake. Unfortunately, healthcare workers perform hand hygiene too seldom. If the patient comes down with a care related infection, the suffering will increase.
Rutiner och riktlinjer för förebyggande av smitta på svenska djursjukhus och kliniker
To be able to give optimal care to patients in small animal hospitals, we have to have knowledge about how to prevent the spread of infection. An important part in this is hand hygiene routines. We have to clean hands whenever they are visibly dirty, and disinfect them regularly in between. Another important part is the cleaning and disinfection of the environment in the clinic, and also the cleaning, disinfection and sterilization of medical instruments. Other important parts are isolation of patients with known infections, to wear clothes with short sleeves and to wash them at least once daily, to wear gloves, having short nails and not wearing jewelry when working.
Tidspress och ekonomiskt risktagande
Stress and time pressure is more present in todays labor markets. In financial markets a securities broker is forced to take decisions on investments under high cognitive load and under extreme time pressure. The research of decision under risk gained new ground with the development of the prospect theory and gave us new insights to the decision making of men. Prospect theory has shown that people are risk seekers when dealing with loss decisions and risk avert when dealing with profit decisions. The value function are defined over gains and losses.
