Leder ESBL-producerande bakterier till ökade samhällskostnader i Sverige?

Due to long time of overconsumption of Antibiotic, the possibility of an effective infection treatment is now threatened. Bacteria have begun develop resistant against Antibiotic, witch is most due to bacteria that do not normally develop resistant. These kinds of bacteria produce ESBL, and have made the healthcare costs increase around twice as much, as for bacteria that do not produce ESBL..

Prevalence and antibiotic resistance of Campylobacter spp. in poultry and raw meat in the Can Tho Province, Vietnam

The aims of the study were to investigate the prevalence and Antibiotic resistance of Campylobacter jejuni and Campylobacter coli in chicken and chicken products, and to investigate farmer awareness of Antibiotic resistance development. The study was conducted in the Can Tho province in Vietnam during six weeks in October to November 2008. Ninety-six samples from raw chickens were collected from twelve market places and analysed for the presence of Campylobacter. A total of 96 cloacal swabs from 20 farms were obtained and analysed for the presence of Campylobacter. Farmers were asked to answer eight questions concerning the housing of the chickens, modes of handling sick animals as well as use and knowledge of Antibiotics and resistance development to Antibiotics.

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.

Dose-related selection of Pradofloxacin resistant Escherichia coli

The study evaluated the Mutant Prevention Concentration (MPC) of Pradofloxacin on three Escherichia coli (E.coli) strains, 2 wildtypes and one first-step gyrA resistant mutant. We also measured the value of AUC (Under the Concentration)/MPC that prevents growth of resistant mutants. It is of importance to reach a concentration above MPC that prevent E.coli from developing resistance against the Antibiotic.We used an in vitro kinetic model where we added bacteria? and Antibiotic. The culture flask was attached to a pump with an adjustable pump-speed.

Cissus Quadrangularis Linn

The aims of the study were to investigate the prevalence and Antibiotic resistance of Campylobacter jejuni and Campylobacter coli in chicken and chicken products, and to investigate farmer awareness of Antibiotic resistance development.

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.

Cleaning process of abattoir wastewater with focus on bacterial pathogens

This study was conducted at the City Abattoir in Kampala, Uganda to evaluate the cleaning process, with focus on bacterial pathogens, in a pilot scale integrated bioprocess. This consisted of four steps: anaerobic sequencing batch reactors; aerobic/anoxic sequencing batch reactors; a high performance temperature controlled methanogenesis digester and a constructed wetland. The objective was to determine if this type of cleaning process could be used to clean wastewater from abattoirs in a satisfactory way. The indicator organisms for faecal contamination, Escherichia coli and Enterococcus spp. were used to investigate in what numbers bacteria could be found in the untreated wastewater and how much that was reduced in the different steps of the cleaning process. The water was analysed for Salmonella to see if human pathogens could be found and could survive the different steps of the treatment process.

Förskrivning av antibiotika till hund vid veterinärhögskolan i Nantes, Frankrike :

The purpose of this retrospective study was to investigate the prescription of Antibiotics to dogs at the small animal clinic at Ecole Nationale Vétérinaire, Nantes, France. The purpose was also to compare the possible prescription patterns in France with those seen in a similar study by Petersson (2003) at the small animal clinic at the Swedish University of Agricultural Sciences, Uppsala. Antibiotics are very important in veterinary medicine and are used both to treat infections and to prevent them. The use of Antibiotics however is not without complications and the risk of developing antimicrobial resistance is of most concern. Resistance has been shown to exist against all currently known Antibiotics and potentially all pathogenic bacteria could develop resistance to one or more Antibiotics. This study analysed the case records for all dogs presented to the small animal clinic at Ecole Nationale Vétérinaire, Nantes, France during October 2001 and March 2002 to identify patients which were treated with systemic Antibiotics. For these cases the Antibiotic used, classified according to the ATCvet system, and the indication for use was noted. A total of 292 cases (146 per month) resulted in administration of systemic Antibiotics.

Behandlingsresultat av kliniska mastiter : en studie av mastitbehandlingar utförda i mjölkkobesättningen på Jälla naturbruksgymnasium 1997-2008

Mastitis is an important disease in dairy cattle. It is very costly for the farmers and affects a large number of animals. Few studies have been made investigating the outcome of treatment for acute clinical mastitis under Swedish conditions, and it can be problematic to use the results in foreign studies since both the microbial flora as well as treatments may be different from the situation in Sweden. In this project we have investigated data on clinical mastitis and Antibiotic treatment in the dairy herd at Jällaskolan, Uppsala based on recordings during the last ten years. The material includes both Swedish Red (SRB) and Swedish Holstein (SLB) breeds, which have been kept at the farm under similar conditions.

Antibiotic resistance associated with bacteria in irrigation water : a case study of irrigation ponds in Southern Sweden

The focus of this project was to characterize the occurrence of ESBL-­?producing bacteria in two irrigation water ponds in Southern Sweden. Samples were taken from two ponds nearby each other, from which analyses were made based on levels of community and individual isolates. Community samples were used for attempts for characterization of resistance patterns in irrigation water using the Omnilog PM-­?plate system. The growth of community microbiota in the presence of the following Antibiotic substances was assessed; amikacin, gentamicin, kanamycin, penicillin G, ampicillin, piperacillin, trimethoprim, potassium tellurite and ciprofloxacin. Isolates were pure cultured using semi-­?selective media: LB, Rainbow Agar, mEnterococcus, 0.1 TSA and VRBD. A total of 177 isolates were isolated randomly. Each isolate was identified using the Omnilog GENIII-­?system of biochemical characterization. Further, the isolates were tested on Brilliance ESBL-­?agar for their ability to grow. Out of the total number of isolates, 30 were selected, preferably Enterobacteriaceae or Pseudomonas spp., based on their high similarity to library strain during the identification in the Omnilog-­?system. These were further characterized using Etest-­?sticks. Three selected strains were picked for further analyses using exogenous isolation for attempts to simulate horizontal gene transfer, and Omnilog PM-­?panels containing various Antibiotics of interest. Selections of samples were chosen for molecular tests targeting plasmid-­?borne resistance genes CTX-­?M1, CTX-­?M2 and SHV. The method for assessing community-­?resistance patterns showed ambiguous data that was difficult to interpret; further optimization is recommended. For all tested PM-­?plates, generally greatest differences between substances were found among wells with the strongest concentration of Antibiotic substance. A total of 175 isolates displayed ability to grow on ESBL-­?agar. Etests confirmed ability of isolates to resist many ?-­?lactam Antibiotics and many were clinically resistant to certain substances. No plasmids were transferred during exogenous isolation. During molecular tests, a few matches were found for the CTX-­?M1 gene. Isolates analyzed with Omnilog PM-­?plates showed resistance to most compounds tested. The isolates showed greatest resistance toward penicillin G, ampicillin, amikacin, kanamycin and trimethoprim. In the study, it was established that resistance among bacteria was frequently occurring in the irrigation water, and ?-­?lactamase producing bacteria was very common. Extended studies are needed to assess the frequency-­? and occurrence of horizontal gene transfer (HGF) in this environment. Although some potential corresponding data is found, it is at this point not possible to determine whether the resistances are due to Antibiotics used in veterinary medicine, human medicine or one additional reason is travel and trade. in irrigation water using the Omnilog PM-­?plate system.

Undersökning av potentiella probiotiska organismer i tarmmikroflora hos häst med speciell hänsyn till Lactobacillus spp. :

The aim of this study was to isolate and identify Lactobacillus species indigenous to the gastrointestinal microflora of Swedish horses. These lactobacilli are to be used as probiotic candidates in research concerning Antibiotic-associated diarrhoea in horses. Eight horses, age 6-10 years, were selected from a riding school for collection of faeces samples. Man Rogosa Sharp medium and gram staining were used for the selection of supposed lactobacilli. We could identify 33 isolates of supposed lactobacilli. With the use of API tests 22 of these 33 isolates could be identified.

Lactobacilli in the gastrointestinal tract of dog and wolf : isolation, identification and characterization of L. reuteri

Since the first wolf was taken as a companion animal a lot have happened with the biology of these animals. Is it possible that changes in the gut microbiota of the domestic dog are involved in the increasing numbers of animals with gastrointestinal disorders? Probiotics have been proven to promote the immune system of dogs by increasing concentrations of neutrophils and monocytes, decreasing the fragility of erythrocytes and increasing the serum IgG concentrations. Probiotics have also been shown to improve the fecal consistency, fecal dry matter and defecation frequency of dogs. The aim of this study was to find out if the bacterial counts in the gut of dogs differed from the gut of wolves, with the focus on lactobacilli.

Antibiotikaresistensgener: förekomst och spridning i akvatisk miljö

Antibiotikaresistens hos bakterier har de senaste årtionden ökat drastiskt och är idag en av de största medicinska utmaningarna samhället står inför. Resistensutvecklingen har ökat i takt med den oförsiktiga användning av antibiotika som präglat både sjukvård och djuruppfödning i många år. Via akvatisk miljö har antibiotikaresistensgener stora möjligheter att spridas och är svårkontrollerbara. Den här litteratursammanställningen undersöker vilka ursprung antibiotikaresistensgener i akvatisk miljö kan ha och om det kan ske en horisontell genöverföring mellan bakterier. Vidare undersöks olika risker med antibiotikaresistensgener i akvatisk miljö, vilken möjlig roll de kan ha i resistensutvecklingen och hur de kan spridas tillbaka till människor och landlevande djur. Antibiotikaresistensgener i akvatisk miljö kommer ifrån utsläpp av resistenta bakterier från djuruppfödningar, akvakultur, sjukhus och bostäder.

Såromvårdnad med antiseptiska medel hos häst

Clinicians in veterinary practice have responsibilities for the development of global Antibiotic resistance. In some cases, Antibiotics are contraindicated or even useless in wound treatments and therefore other options are needed. Antiseptics may be another option but their use are controversial and may be questioned by owners. As professionals, it may be very difficult to be able to motivate this choice of treatment. The aim of this paper is to gain knowledge about four antiseptics; iodine, silver, polyhexamethylene biguanide (PHMB) and honey to make it easier for veterinary nurses and other clinicians in veterinary practices to decide their potential use. The assessment will be made with consideration of the available evidence concerning the properties, usability and the animal?s experience. The results showed a lack of evidence in in-vivo studies in horses, particularly studies within the field of veterinary nursing.

When does the protein profile in milk normalize after antibiotic treatment against clinical mastitis?

Concentration of protein in bovine milk is one of the most significant milk quality parameters, to a large extent determining the price for milk to the producer. Mastitis is a common disease among dairy cows, negatively affecting not only milk yield but also milk protein composition. Milk from mastitic cows tends to have lower cheese yield, negatively affected processability properties and sensory quality, due to changed protein quality and composition. Poorer milk protein quality would have an economically negative impact on dairy industry. Only few studies have investigated the short term effects of mastitis on milk protein composition.
