This risk of infection can be influenced by various factors, including perioperative antibiotic prophylaxis. In terms of antibiotic stewardship, antibiotics should only be used if there is a proven benefit for the patient. However, this advantage has not yet been conclusively proven, especially for clean and clean-contaminated surgeries. The aim of our study was to document various relevant influencing factors on the infection rate after clean and clean-contaminated surgeries in dogs and cats. In particular, it was documented to what extent a reduced use of antibiotics affects the infection rate in the context of all influencing factors. Over a period of eleven months, 807 clean and clean-contaminated surgeries in dogs and cats were prospectively analyzed with possible influencing factors (gender, ASA classification, underlying endocrinological diseases, duration of anesthesia, duration of surgery, type of surgery, perioperative antibiotic prophylaxis (POA), duration of hospitalization) affecting the infection rate. After surgery all cases were followed up either 30 or 90 days, if implants were used. The effect of the various factors was evaluated using multivariable logistic regression analysis. SSI was detected in 25/664 clean and 10/143 clean-contaminated surgeries. Longer hospitalization, without antimicrobial prophylaxis, and male animals had a significantly higher risk of SSI. In clean surgeries, SSI occurred in 2,3 % of all cases with POA and 5,3 % without POA. The SSI in clean-contaminated was 3,6 % with POA and 9 % without. This difference resulted mainly from the results of osteosynthesis, gastrointestinal and skin surgeries. However, other types of surgeries, such as castrations, neurological interventions, abdominal and thoracic surgeries, and surgeries in the head and neck region, showed comparable infection rates with and without POA.</p>","PeriodicalId":21544,"journal":{"name":"Schweizer Archiv fur Tierheilkunde","volume":"165 4","pages":"250-0"},"PeriodicalIF":0.7,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9257019","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The survey was sent to equine veterinarians according to the member database of the Swiss Veterinary Association (GST, SVS). The demographic data of the respondents and their antibiotics usage were collected. In addition, six different case scenarios were presented with questions to their potential antibiotic usage, active substance/preparation and the dosing scheme. The dosage provided was compared with the dosage information approved by Swissmedic in the information for healthcare professionals and the recommendations of the antibiotic scout. A backward logistic regression analysis was performed to assess the association between different aspects of antibiotic use and demographic data. The response rate was 94/739 (13 %), 22 of the 94 (23 %) had also participated in the 2013 study. 47/94 (50 %) of the respondents obtained their information from the antibiotic scout. The respondents indicated that they used an antibiotic in 16 %-88 % depending on the case scenario. Neither 3rd nor 4th generation cephalosporins or fluoroquinolones were used in the case scenarios. Dihydrostreptomycin was indicated as a possible antibiotic in a case scenario by 14/94 (15 %) of the respondents.

Various studies have shown a similar pathogen spectrum as in dairy cows, which could not be confirmed in this study. To gather initial data from Switzerland, milk samples from 297 lactating beef cows from 31 herds from the Engadin Valley in the Canton of Grisons were examined bacteriologically. At least one major or minor mastitis pathogen was recovered from at least one individual-quarter or composite sample from 33 % of all cows. The most common major mastitis pathogens were Staphylococcus aureus (8,4 % of cows), Pasteurella multocida (4,1 %), Streptococcus uberis (2 %) and Streptococcus dysgalactiae (1,7 %). Sixteen percent of the cows had at least one blind quarter, but only 32 % of these had been previously detected by the owners. In the second part of the study, milk samples from beef cows with mastitis were examined bacteriologically; the cows originated from various parts of Switzerland and had been presented for veterinary treatment. Pasteurella multocida (22 %) and Staphylococcus aureus (21 %) were the most common pathogens isolated. Antibiograms using microtitration and disk diffusion testing were generated for the Staphylococcus aureus, Pasteurella multocida and Streptococcus uberis strains from both parts of the study. Fifty-six percent of the Staphylococcus aureus strains were resistant to penicillin G. Our results showed that bacteriological examination of a milk sample aids in the diagnosis and allows specific treatment of mastitis in beef cows; this may be further improved with antibacterial susceptibility testing. Our preliminary data for the resistance patterns of mastitis pathogens in beef cows will facilitate evidence-based treatment strategies.","PeriodicalId":21544,"journal":{"name":"Schweizer Archiv fur Tierheilkunde","volume":"165 1","pages":"39-51"},"PeriodicalIF":0.7,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10802341","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many adverse effects are associated with this medication, however most of them rarely occur. A 5-year-old, female intact French bulldog was presented with multiple, multifocally distributed, severe hyperkeratotic and papillomatous/verrucous plaques. The dog was on long-term immunosuppressive treatment with cyclosporine for meningoencephalitis of unknown origin (MUO). It had an history of atopic dermatitis and calcinosis cutis. A papillomavirus infection was excluded by polymerase chain reaction (PCR), and histopathologic analysis revealed a chronic lymphoplasmacytic non-specific dermatitis, perifolliculitis and periadnexitis and focal folliculitis with papillomatous epidermal hyperplasia and orthokeratotic hyperkeratosis. The diagnosis of \"cyclosporine-induced epidermal hyperplasia with secondary pyoderma\" was made. Cyclosporine was discontinued and as an alternative mycophenolate mofetil was started to control the MUO. An antimicrobial treatment was prescribed for three weeks. After four months, the skin lesions had healed completely. To date after 2 years, the dog is still in remission. The occurrence of hyperplastic lesions associated with cyclosporine therapy have already been described in previous reports. Most of them resemble those of psoriasiform lichenoid dermatitis, although papilloma virus may be detected in some instances. The dog of the present case showed some peculiarities in the histopathological findings, and a papillomavirus involvement was ruled out with PCR. Like observed in a previous report, there was no correlation between cyclosporine blood level and the severity of dermatological changes.

Furthermore, the population suffered of apathy, anorexia, severe weight loss and conjunctivitis, as well as abortions and stillbirths. At the same time, the owner experienced a SARS-CoV-2 infection with pneumonia, which was confirmed by taking a PCR test. Chlamydia caviae was detected from the conjunctiva and vagina/uterus in one juvenile animal together with an intestinal Cryptosporidium wrairi infection. Oocysts were found histologically in the small intestine, which was confirmed by PCR. C. wairi is a parasite adapted to guinea pigs with zoonotic potential, which causes diarrhoea with frequent deaths in larger guinea pig herds. C. caviae is also a zoonotic pathogen and often the cause of conjunctivitis, pneumonia and abortions in guinea pigs and can lead to upper respiratory tract disease, conjunctivitis but also severe pneumonia in humans. The increased death cases and the clinical signs could be traced back to an infection with Cryptosporidium wrairi, complicated by a co-infection of C. caviae. We suspect that the abortions were caused by C. caviae, but since the population was treated with various antibiotics effective against chlamydial infections, it was no longer possible to verify this by PCR testing. Unfortunately, more animals succumbed and finally only two animals of the originally 26 were left.
