Evaluation of Lactobacillus reuteri DSM17938 as starter in cheese production

The probiotic bacteria Lactobacillus reuteri DSM17938 was evaluated as a starter culture in cheese production, with the intention to produce a new interesting product within the functional food market. Growth and acidification rate in milk subjected to different heat treatments, as well as supplementation with growth promoting factors or support cultures was measured during controlled fermentations. The results showed that the weak proteolytic activity of L. reuteri could be compensated for by supplementation with 1% casamino acids or 5% MRS broth. Furthermore, a decrease in growth and acidification rate could be seen when using yoghurt culture or Lactobacillus delbrueckii as adjunct cultures.

Infektionssjukdomen kolibacillos hos värphöns : orsaker till uppkomst och åtgärder för reducerad utbrottsrisk

Förekomsten av sjukdomen kolibacillos har ökat inom besättningar med värphöns. Utbrott av sjukdomen orsakar ekonomiska förluster inom alla produktionsgrenar av fjäderfä. Ett samband kan ses mellan ökningen av antalet kolibacillos-utbrott och den ökade andelen frigående besättningar. Flertalet parametrar i hönsens omgivande stallmiljö inverkar på känsligheten för infektion. Producenten bör lägga vikt vid att kontrollera ventilationen i stallet för att hålla kontroll på ammoniak, damm, luftflöden, luftfuktighet och temperatur, vilka samtliga inverkar på spridningen och infektionspotentialen hos sjukdomsframkallande sk.

Hälsa i ämnet idrott och hälsa- En kvalitativ undersökning om lärares syn på hälsa.

Hälsa är ett begrepp som har avsaknad av en bestämd definition. Det finns flertalet erkända definitioner såsom WHO:s men det finns även de definitioner som skapats av den enskilda individen. De flesta definitioner som finns kring och om hälsa har sitt ursprung i den fysiska aktivitetens värld, än dock menar flera personer att om hälsa enbart skall ses som god utifrån den fysiska aktiviteten så blir begreppet hälsa inte särskilt innehållsrikt. Syftet med studien var att undersöka hur lärarna ser på begreppet hälsa. Enligt bakgrund och tidigare forskning så är hälsa ett personligt och svårdefinierat begrepp, vilket de sex lärare som intervjuades i denna kvalitativa studie bekräftade.

Porcine viruses in Uganda : a study of TTSuV and PPV4 in wild and domestic pigs

Uganda has the largest pig population in east Africa, and most of the animals are owned by smallholders. Infectious diseases among pigs have a devastating impact on the livelihood of these farmers, which are dependent on the proceeds from pig rearing. In a metagenomics study of the wild pig species bushpig (Potamochoerus larvatus), the porcine viruses Torque teno sus virus (TTSuV) 1and 2 and Porcine parvovirus 4 (PPV4) were detected. TTSuV1 and 2 are ubiquitous in the world?s swine population, and PPV4 has been found in USA and China, but neither of them has been studied in Africa previously.

Hydrofob interaktion : en resurs för att reducera antibiotikaanvändningen

It is important to know what is normal in the wound healing process in order to determine what happens when a wound does not heal as expected. If the amount of bacteria in the wound gets too large the body will not be able to defend itself and it becomes an infection. Colonization and infection are common elements in wound management and it is often the veterinary nurse role to deal with wounds in a proper manner. Antibiotics are drugs that either kill or inhibit the multiplication of bacteria or fungi, and have been in veterinary medicine for approximately 60 years. Very few new antibiotics are introduced and increased resistance is a major problem that requires everyone to take responsibility to reduce the use of it.

Isolating microorganisms from marine and marine-associated samples : a targeted search for novel natural antibiotics

The search for antibiotic compounds from the natural environment has been going on for seven decades, ever since penicillin entered the market and antibiotic treatments became routine. The evolutionary pressure put on the Pathogenic microorganisms induced a rapid spreading of naturally occurring resistance genes, leaving only the option of finding new antibiotics to treat the resistant pathogens. Microorganisms have been extensively mined for their biosynthetic abilities to produce biologically active compounds. To date, more than 23 000 microbial natural products have been discovered. The Actinomycetales are ubiquitous bacteria that have been used for antibiotic discovery for more than half a century, and over 10 000 natural products have been identified from the order.

Konst och kultur : Möjligheter och hinder att använda konst och kultur som rehabiliterande metod inom primärvården

Background:There are future challenges for public health and health care in meeting the needs of a growing and ageing population. Today there are evidence of how arts can contribute to health development and of the connections between arts, health, treating and rehabilitating measures. To be able to meet the future challenges there is a need for new methods, perspectives and views about how to stay healthy, enjoy our existence and for wellbeing. Health care has an important role in rehabilitation through the broad contact with the population. The background of the essay is the pilot project Arts on Prescription that was carried out in order to try a new way of rehabilitation with arts as a factor.

Livsmedelssäkerhet för skolor, förskolor och äldreomsorg i Varbergs kommun; HACCP för tillagnings- och mottagningskök

One of the main objectives of all food production is to produce foods that can safely beconsumed without fear of being sick. Despite this hundreds of people are affected in Sweden offood poisoning almost every day. Most cases are caused by a small group of so-called Pathogenicmicroorganisms. The most frequently affected are the small children, the elderly, persons withreduced resistance and pregnant. The reasons behind the food poisoning are often ignorance andlack of food hygiene.

Compost and its effects on soilborne plant pathogens

Certain microbial residents from composts are known to possess the ability to suppress soilborne plant pathogens. Trichoderma spp. and Gliocladium spp. are commonly found in composts and are perhaps the most wellknown hyperparasites of fungal pathogens, which may also be naturally present in compost. Trials have many times proven them to be effective against plant diseases caused by soilborne pathogens such as Pythium spp., Phytophthora spp.

Klövhälsa hos får : ur ett nationellt och internationellt perspektiv

Lameness causes suffering and poor performance in sheep, as in other species. The cause of lameness often originates in problems of the claws. Many claw diseases of sheep are described in British and Australian research, but this field has previously not been of special concern in Sweden. This graduate thesis contains the first claw health survey made on Swedish sheep. The chief objective was to give an overview of sheep claw diseases and to assess claw health in adult sheep.

Institutionens betydelse för människors hälsa : en livsberättelsestudie om äldres uppfattningar om hur det är att bo på äldreboende

Antalet äldre blir idag allt fler och behovet av vård flyttas upp i åldrarna. Det kräver att insatser inom äldrevård och omsorg håller hög kvalité och placerar människan i centrum för att skapa förutsättningar för äldre att leva ett värdigt, meningsfullt liv och känna välbefinnande. Frågan om mat, trygghet, identitet, social interaktion, anpassning och KASAM är faktorer som påverkar äldres tillvaro på äldreboende. Syftet med studien var att få djupare kunskap och förståelse i äldres livsvärld på äldreboende, hur man som boende upplever sin vardag och vilken betydelse äldreboendet som institution har för deras hälsa. Två livsberättelseintervjuer genomfördes under en timme var med två äldre, en man och en kvinna boende på ett äldreboende i Mellansverige.

Interactions between some plant-parasitic nematodes and Rhizoctonia solani in potato fields

The Pathogenic fungus Rhizoctonia solani causes major economic losses for potato producers in Sweden. The producers, as well as advisors, have reported possible increases in severity of R. solani when free-living plant parasitic nematodes are present and active. There are several examples in the literature of interactions between pathogens where one, or both species, support or increase the damage made by the other organism. These complexes are important to investigate and to be able to forecast, since even low incidences of fungi or nematodes may result in an interaction of significance.

Vaselin som kontroll vid försök med 1 % väteperoxidkräm i färska hudsår på häst

Wounds on horses are common and sometimes difficult to treat. The wounds are often big and could be discovered too late for primary sutures, which have to be applied within 8 hours from time of accident, before bacteria has been able to infiltrate the surrounding tissue. The healing is often complicated by delayed healing and wound infection with consequences like phlegmone, fistulation and proud flesh formation.To avoid these consequences, the traditional practice has been to administer systemic antibiotics alone, systemic antibiotics in combination with topical antibiotics or topical antibiotics alone. Because few antibiotics can be used in horses, is it important to household with the few substances that are available. In veterinary medicine today, the increasing resistance amongst Pathogenic microbes such as MRSA presents a growing problem.

Potentiella virala zoonoser hos apor på svenska djurparker år 2008

This paper is a compilation of some of the important viral zoonosis that can be passed from apes and simians (simian and prosimian) to man. Viral zoonoses are viral diseases that can be passed from animals to humans. The paper will also provide a better insight of the risks workers and visitors to the zoo can be exposed to. The viruses that this paper is focused on is herpes Bvirus, simian T-lymphotropic virus type 1 (STLV), simian immunodeficiency virus (SIV), Ebola virus, Marburg virus, yellowfever virus, monkeypoxvirus and hepatitis B virus. The choice of viruses is based on how infectious they are and how Pathogenic they are.

Optimerad hygienisering vid kompostering av avloppsslam

The aim of this study was to in laboratory experiments investigate how addition of urea, ECOX and structural materials can optimize sanitization during composting of sewage sludge. Today we strive for a sustainable society and the importance of closing the nutrient loop increases. It has therefore become even more important to safely reuse plant nutrients from human excreta to agricultural land. Partly because it increases the sustainability of society as the world's supply of many nutrients are finite, partly because it promotes human health, both by reducing disease transmission and by increasing Agricultural production. An untapped resource such as sewage sludge that is rich in nutrients and humus-forming materials could replace parts of the commercial fertilizers used in Sweden today. owever, sewage sludge contains undesirable substances such as heavy metals and drug residues, and Pathogenic microorganisms.
