This paper evaluates the prospects for utilizing aquaculture effluents as a nutrient source in organic hydroponic, as is the case in aquaponics. The development of organic hydroponics is dependent on replacing synthetic fertilizers with organically derived nutrients, such as those found in aquaculture effluents. Also, in hydroponic cultivation the establishment of a plant pathogen suppressive micro flora is part of the plant protection strategy. Therefore, both nutritional and microbial qualities of aquaculture water and organic hydroponic nutri-ent solution were analyzed and compared. Results showed both aquaculture water and or-ganic hydroponic solution to be deficient in a number of essential elements, although or-ganic hydroponic solution was closer to recommendations.

Clostridium difficile is a pathogen for both humans and animals and is often associated with antibiotic-associated diarrhea. Recently, several human cases of C. difficile-infection with increased mortality and morbidity have been reported. In studies performed in different countries C. difficile has been found in meat.

Perch (Perca fluviatilis) is a very popular fish in Sweden and it is common in Swedish waters. In some areas along the Swedish coast the perch population has decreased. It is therefore important to get a view at the health status of perch. During April, July and August of 2008, a total of 346 perches were caught in the Gump Bay in the Botnian Sea. The fish were mainly caught by net but also by rod.

Background: Postoperative infections are a serious patient safety problem and affects about 3 % of all patients undergoing surgery. The consequences are prolonged hospital stays, high social costs, increased use of antibiotics and impaired quality of life for the patient. It has been shown that postoperative infections may be caused by contamination already in the operating room. Today we know that there is growth of microorganisms on the instrument table´s top, but there is a research gap about the instrument table's edges.Aim: To examine if the sterile drape on the instrument table´s edges are sterile after finished surgery.Method: Contact plates are printed on strategically selected areas on the sterile drapes top and edges. In the pilot study, a total of 51 cultures were taken at the end of three operations which lasted over three hours.Results: Growth on the top surface and the edges of the sterile drape were detected.

Acute Bacterial prostatitis is a common disease in older male dogs. It gives symptoms such as fever, pain, tiredness, infertility, unwillingness to mate and sometimes symptoms from the urinary tract. It is common that you do an ultrasound exam on dogs when you suspect prostatic changes. In this study 15 dogs diagnosed with acute prostatitis at the small animal clinic at SLU in Uppsala were examined. The clinical signs and the ultrasound pictures were put together in retrospect.

The genus Borrelia is a widespread, pathogenic pest and the causative of among others borreliosis or Lyme disease. The vector for the Bacteria is the hard tick, Ixodes ricinus and the infection is transferred through a bite. Untreated, Borrelia may cause arthritis, heart damage or neuroborreliosis. Infection is made possible through different strategies for avoiding the body?s complement system.

Pastern dermatitis is a common condition among horses. It is a symptom, a reaction in the skin of the pastern rather than a diagnose. There are a lot of homemade treatments when you ask horse owners how they handle pastern dermatitis, but what does the science say about how it should be treated? Today there is a growing problem with antibiotic resistance, but how good are the veterinarians on testing for resistance before they describe antibiotics? Bacteria and fungus is seldom the primary cause for pastern dermatitis, the reaction is often secondary to environmental factors. It?s difficult to diagnose the primary factor and it´s even more difficult when the horse has been treated in different ways before the veterinarian gets involved.

Pyometra, chronic purulent metritis in metoestrus, is a common disease in intact bitches. About 25% of all bitches in Sweden have contracted the disease before ten years of age. Clinical signs of the disease are varied, and the course may be either slow or acute. The diagnosis is most commonly made by radiographical or ultrasonographical examination of the abdomen in combination with blood biochemical and hematological analyses. The safest and most efficient treatment of pyometra is surgical ovariohysterectomy.There is room for improvement of both diagnostic tools and possible prognostic indicators for pyometra.Mast cells are large leucocytes, with granule that contain inflammatory mediators.

In Sweden, all milk needs to be pasteurized. Unpasteurized milk [ OPM ] may only be sold in a smaller scale directly from the farmer to the consumer. The law was introduced in 1939, to prevent tuberculosis, which poses no threat today. There are other reasons, such as keepability and risk of pathogenic Bacteria, why milk is pasteurized. Despite these risks, many consume OPM.

Osseointegrated titanium implants have become a commonly used method in edentulous jaws and today there are success rates in the magnitude of 82 % in the lower jaw and 98 % in the upper. During first year after implantation a fully normal marginal bone loss of 1-2 mm occurs. If the bone loss continues there is a risk of implant failure. High tensions in bone and inflammation caused by Bacteria are possible reasons for this problem. It has been shown that a leakage of Bacterias occurs between the parts of the implant and there are theories that this has effects on the marginal bone loss. The aim of this thesis has been to increase the knowledge about microbial leakage with help of in vitro tests and virtual simulations.

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.

Lawsonia intracellularis is an important pathogen in the intestine, causing diarrhea and retarded (or poor) growth in pigs. Diagnostics is based on sampling of small amounts of faeces. Several publicated scientific papers mention the use of faecal swabs as sampling material for diagnosis in experiments and in prevalence studies. Therefore the need of an evaluation of this sampling technique is urgent since, to our knowledge, this has not previously been done. Here reported work compare the use of rectal swabs for feacal sampling, with sampling and analysis of 0.1-0.2 gram of faeces. The studie included twelve herds with a case history of earlier or ongoing problems with diarrhoea where Lawsonia intracellularis could be suspected as the causative agent. A total of 120 growing pigs where examined.

This work is about silage contaminated with slugs (Arion lusitanicus). The hypothesis was: Do slugs affect the nutritional value and hygiene quality of silage? During the winter season 2007/2008 silages were discarded in big amounts due to the contamination of slugs. Both the Swedish Farmer Association (LRF) and the National Veterinary Institute (SVA) received phone calls from farmers and animal owners about contaminated silage. The Swedish University of Agricultural Sciences (SLU) and SVA decided to initiate this project as a master thesis.

Hemoglobin is built up from protein and heme groups which give the blood its red colour . Hemoglobin transports oxygen and carbon dioxide between the lungs and other tissues in the body. Normally, a piglet has a hemoglobin value of 130-150 gram per liter blood, and the lower limit before anaemia appears is 80 grams per liter blood. The immune defense is also dependent upon the presence of iron in hemoglobin, since iron participates in different enzyme systems. When the piglet develops anaemia, it becomes pale and thicker around the neck.
