There is an urgent need to refine the use of different antimicrobials to avoid the problem of antimicrobial resistance and optimize the control of this disease in ovine livestock. The first step in approaching this problem is gaining an insight into the antimicrobial susceptibility of ovine pathogens. This study evaluated the in vitro activity of tildipirosin, gamithromycin, oxytetracycline, and danofloxacin against Pasteurella multocida strains isolated from sheep with fibrinous pneumonia. The strains were incubated following Clinical and Laboratory Standards Institute (CLSI) standard conditions and also with a modified method by 25% supplementation with sheep serum. Minimum inhibitory concentrations (MIC) were determined using the broth microdilution technique. The lowest MIC90 under standard conditions and by supplementation with sheep serum was obtained with tildipirosin. Sheep serum significantly reduced tildipirosin, gamithromycin, and danofloxacin MIC values for Pasteurella multocida strains. In brief, the potency of tildipirosine, gamithromycin, and danofloxacin against Pasteurella multocida increases when sheep serum is added to the culture media.","PeriodicalId":55559,"journal":{"name":"Acta Veterinaria-Beograd","volume":"73 1","pages":"171 - 178"},"PeriodicalIF":0.6,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44172732","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}

Allergen-specific immunotherapy (ASIT) aims to reduce or eliminate symptoms associated with subsequent exposure to the causative allergen. The primary outcome of this study was to determine if the quality of life (QoL) of cats and owners improved as a result of ASIT. The secondary outcome was to determine whether the QoL improved in cats treated with ASIT compared with cats treated symptomatically. Eight cats were included in the ASIT group (AG) and 6 cats in the control group (CG). Validated quality of life questionnaires were retrospectively completed by cat owners for the period before and after treatment. The QoL of cats improved significantly with ASIT. Cats were significantly less lazy, nervous, aggressive, restrained, preened less while sleeping and hid less, were less disturbed by consultations, were more playful and interactive with their environment, and had better appetites than before treatment. Owners felt significantly less physically exhausted and less emotionally distressed compared to before ASIT treatment and their expenses were significantly lower. On the contrary various symptomatic treatments did not significantly improve the quality of life of the cats or their owners in any of the terms. No serious side effects were observed with ASIT. The quality of life of animals suffering from chronic diseases is important as it determines the decisions of owners and veterinarians on the modalities of lifelong treatment. Validated questionnaires are still rarely used in veterinary practice and research.","PeriodicalId":55559,"journal":{"name":"Acta Veterinaria-Beograd","volume":"73 1","pages":"205 - 217"},"PeriodicalIF":0.6,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42429926","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}

Since then, more than 1.3 million domestic pigs have been infected in more than 5600 backyard holdings and commercial farms all over Romania where stamping out procedures have been performed afterwards. The spread of the disease could not be contained despite the contingency plans developed by the authorities based on the current EU and Romanian legislation, and currently, the entire territory of Romania is considered to be affected, leading to a significant decline of the pig inventory and major damages in the commercial farming system. Consequently, the amounts of pork imported from other EU member states have increased yearly, pig meat becoming the main commodity on the list of agricultural goods purchased by Romania. 2021 has been by far the worst year for Romanian pig meat production, generating the highest financial losses mainly due to the inability of authorities and policymakers to implement effective and efficient disease control measures.","PeriodicalId":55559,"journal":{"name":"Acta Veterinaria-Beograd","volume":"73 1","pages":"1 - 12"},"PeriodicalIF":0.6,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42890085","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}

This study aimed to determine the prevalence of intestinal parasites in dogs and cats and proceed to infection comparisons between young and adult animals. The detection of parasites in fecal samples was determined using flotation and immunofluorescent methods across 320 dogs and 64 cats from the Kvarner region in Croatia. The prevalence was calculated for each detected parasite in its host. Differences in prevalence between young animals and adults were analyzed. Parasites were detected in 32 dogs and 34.4% of cats. In total, 12 different genera were detected; Giardia spp. was the most prevalent parasite in both species, infecting 24.7% and 18.8% of investigated dogs and cats, respectively. Cryptosporidium spp. and Toxocara cati had a prevalence of (18.4%) and (6.3%), respectively. Prevalences of Giardia spp., Cryptosporidium spp., and Cystoisospora spp. were significantly (P < 0.05) higher in puppies compared to adult dogs. Pentatrichomonas hominis (P. hominis) was detected in one puppy.

The lumbar vertebra morphometry test was performed by means of X-ray imageing obtained from 12 guinea pigs, with equal numbers of males and females. The results of investigations show that guinea pig lumbar vertebrae have an irregular trapezoid geometry and that the measured body lengths of L4 and L5 are the largest. The height parameters determined in the medial level showed that L4 had the most concave body. Moreover, L4 had the greatest depth of the spinal canal at the same measurement level. Consequently, in guinea pigs, the greatest load is in the L4 region, unlike in humans, where, due to the axial load of the spinal column, the highest pressure is exerted on the last lumbar vertebrae.","PeriodicalId":55559,"journal":{"name":"Acta Veterinaria-Beograd","volume":"73 1","pages":"55 - 70"},"PeriodicalIF":0.6,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46027753","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}

Treatment options include radiation therapy, chemotherapy, or a combination of both modalities. Radiation therapy (RT) in a combination with chemotherapy lead to median survival from 19 months to 955 days. The objective of this paper is to report a case of a large cell late stage invasive feline nasal lymphoma and to evaluate the results of orthovoltage radiation therapy and its side effects. A 12-year-old female mixed breed cat was presented with nasal discharge, sneezing and hyporexia. Definitive histopathology diagnosis was diffuse large cell lymphoma. Computed tomography revealed an advanced stage of the disease, an intranasal mass, bone lysis, invasion of the orbital space and central nervous system. A radical course of X-ray therapy was performed (SFD = 4 Gy, TSD = 40 Gy, 10 sessions, 3 times a week). Radiation side effects were well tolerated and resolved with supportive treatment. Lymphoma is a systemic process and requires a multidisciplinary approach. On most cases, the penetrating ability of radiation therapy of 3.5 cm in depth is enough for small domestic animals. A significant effect is noted in the middle of the treatment course. The fractionated regime did not cause early radiation damage. The relapse-free period was up to 8 months. The patient had a satisfying quality of life for 5 months. Orthovoltage X-ray therapy can be considered as a treatment choice for local nasal lymphoma. X-ray therapy is a widely used modality in veterinary medicine considering the price of machines and costs of treatment.","PeriodicalId":55559,"journal":{"name":"Acta Veterinaria-Beograd","volume":"73 1","pages":"143 - 154"},"PeriodicalIF":0.6,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43380011","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}

Most FCoV-infected cats remain asymp tomatic, but up to 10% develop fatal feline infectious peritonitis (FIP). This study aims to investigate the diagnostic utility of clinical and laboratory examinations including serum and effusion AGP levels in cats either with symptomatic effusive FIP or asymptomatic feline enteric coronavirus (FECV). The study included 40 cats with effusive FIP and 10 cats with FECV infection. The FIP group was divided into two subgroups: abdominal (AE; n=30) and thoracic effusion (TE; n=10). Clinical and laboratory examinations, including serum or effusion AGP measurement, were performed. Among all the groups, TE group had higher body temperature, heart and respiratory rates (P<0.000). Compared with the FECV group, the FIP group had lower pH and HCO3 levels and higher base excess and lactate levels (P<0.05). The leukocyte and lymphocyte counts were higher and the hematocrit was lower in the AE group among all the groups (P<0.023). MCV was lower in the FIP group compared to the FECV group (P<0.002). In the AE group, total protein level was the lowest and the AST, GGT, total bilirubin and cholesterol levels were the highest (P<0.032) among all the groups.

Although the serum AGP level was highest in the TE group among all groups (P<0.004), the AGP levels of cats with FECV were similar to the AE group (P>0.05). Since FECV-positive cats will likely develop FIP, differences in clinical and laboratory findings in FECV-positive cats were identified. Among them, pH, HCO3, base excess, lactate, MCV and magnesium were found to be important in the course of the disease, and AGP in the evaluation of the presence of an inflammatory state.

It is considered the leading cause of three syndromes: adenoviral gizzard erosions and ulcerations, inclusion body hepatitis, and hepatitis-hydropericardium syndrome. A critical feature of this virus is its immunosuppressive effect, via suppressing humoral and cellular immunity. In this study, we examined the humoral immune response after administration of the Newcastle disease vaccine in broiler flocks with previously confirmed seroconversion against Fowl adenovirus. The study was conducted on 5 farms. A total of 220 chickens, five weeks of age, showing no clinical signs of the disease, were included in this study. The control group consisted of 20 chickens from a negative farm. Chickens were vaccinated with commercially available live NDV vaccines between 11 and 13 days of life. ELISA determined the presence of specific antibodies against FAdV in a total of 130/200 (65%) blood sera. Depending on the farm, seroprevalence ranged from 30-100%. The presence of specific antibodies against NDV was determined three weeks after vaccination using the hemagglutination inhibition assay. A positive hemagglutination inhibition (HI) titer (≥ 16) was found in 41/200 (20.5%) sera, which was significantly less compared to the control farm, where a positive HI titer was found in 20/20 (100%) sera.
