Ten sets of vertebral biomodels and the corresponding drilling guides were created to evaluate the implantation accuracy in the cervical (C5-C6) and lumbar (L4-L5) vertebrae of cats. Smooth pins were implanted using the guides on the right side of five randomly assigned biomodel sets and on the left side of the remaining sets, with the contralateral side undergoing freehand implantation. Subsequently, a new tomographic study was conducted to measure the implantation angles. The pre-implantation angles were compared with the post-implantation angles between the techniques and among the sets. The guide-assisted implantation exhibited a lower dispersion compared to the freehand technique, with coefficients of variation of -1.95 and 48.9 in the cervical vertebrae and 1.98 and 9.39 in the lumbar vertebrae, respectively. However, no statistical difference was observed between the pre- and post-implantation angles, nor when comparing the vertebral segments (P > 0.05). Under the study conditions, the use of the guide failed to result in more accurate implantations in the C5-C6 and L4-L5 vertebral biomodels of cats.

One of the disorders of the mammary gland in the queen is feline mammary fibroadenomatous hyperplasia (FMFH), caused by an increasing concentration of progesterone (P4) and some other local growth factors. It occurs mostly during puberty after the heat characterised by spontaneous or provoked ovulation, as a result of exogenous progesterone intake and sometimes during pregnancy. To diagnose a 14-month-old intact Maine Coon queen with extensive mammary gland hyperplasia, a clinical examination, analyses of the progesterone (P4) concentrations and ultrasound examination were performed. Feline mammary fibroadenomatous hyperplasia associated with a high P4 concentration after spontaneous ovulation was confirmed. After 24 days of therapy with a progesterone antagonist, aglepristone, the symptoms of FMFH resolved. After the next eight weeks, the queen was mated after the owner's decision. In the third week of pregnancy, a relapse was detected (mammary gland enlargement, pain, discomfort). At the same time, no abnormalities in the uterus or embryos were detected via ultrasound. The P4 concentrations were under regular control. For the next two weeks, only conservative treatment with NSAIDs was used. The queen spontaneously delivered six kittens without any difficulties or perinatal complications 67 days after the first mating. The cat previously treated with aglepristone for FMFH was successfully bred, but FMFH symptoms returned when progesterone concentrations increased during pregnancy.

Dental health has historically received little attention in veterinary medicine, but is becoming more common. This study aimed to report the prevalence of dental extractions in dogs in Seoul, Republic of Korea, describe the current status of dental health and determine any preventive methods. In total, 166 dogs participated in the study, presented to the veterinary hospital with an oral disorder or for a routine check-up were included in the study. Teeth were extracted from 130 dogs (78.32%). A single tooth was extracted from 18 dogs (13.85%), whereas multiple teeth (2-29 teeth) were extracted from 112 dogs (86.15%). Ten teeth were extracted in 31 dogs (27.67%). In descending order, the most extracted teeth were PM2, PM3, PM4, and PM1. The age at the first dental check-up, the average interval between dental check-ups, and the average interval between the previous two dental check-ups in the extraction group were significantly greater than those in the non-extraction group. In contrast, the number of dental check-ups was significantly lower. In conclusion, this study suggests regular dental check-ups to prevent dental extractions. The data provide useful information for veterinary dental health management and the prevention of tooth extractions.

The present study aimed to evaluate the biochemical and antioxidant responses of common carp after exposure to the antiepileptic and analgesic drug gabapentin at concentrations of 0.1, 1, 10, and 100 μg/l for 4 weeks. The exposure to the highest two concentrations resulted in significant changes in plasma indices such as glucose (only group 100 μg/l), alanine aminotransferase (ALT), lactate dehydrogenase (LDH), lipase, creatine kinase (CK), amylase as well as butyrylcholinesterase (BChE). Similar trends were found in both groups exposed to the environmentally relevant concentrations (i.e., 0.1 and 1 μg/l). In addition, a significant increase in the ferric-reducing power of the plasma was noted in all treated groups. Numerous changes in antioxidant enzymes, superoxide dismutase, catalase, glutathione-S-transferase, as well as lipid peroxidation, were observed especially in the caudal kidney in the group exposed to 100 μg/l. Significant findings were also confirmed in the group exposed to an environmentally relevant concentration (1 μg/l), with a decrease in superoxide dismutase in the gill and an increased lipoperoxidation in the caudal kidney. Our research shows that subchronic exposure to gabapentin may pose a significant risk to non-target aquatic organisms, such as disruption of metabolic pathways or induction of oxidative stress, even at environmentally relevant concentrations.

Bovine respiratory disease (BRD) develops from complex interactions among environmental, host and pathogenic factors. This study aimed to phenotypically identify Enterobacter hormaechei isolated from cattle with BRD and assess antimicrobial susceptibility and determining the molecular phylogeny of local E. hormaechei strains. Between November 2023 and March 2024, nasal swabs were collected from 93 cattle with BRD, before culturing for phenotypic analysis, and performing the polymerase chain reaction (PCR) for molecular characterisation. Of the 93 samples evaluated, 15.79% and 24.56% tested positive for E. hormaechei isolates on culture and PCR, respectively. The local isolates exhibited high resistance to amoxicillin, ampicillin, amikacin, nalidixic acid and ceftazidime; high susceptibility to azithromycin, levofloxacin, gentamicin, ofloxacin, cefepime, ceftriaxone, cefotaxime, nitrofurantoin, ceftazidime and ciprofloxacin; and moderate susceptibility to ciprofloxacin, colistin, imipenem and meropenem. Multiple sequence alignment, phylogenetic tree analysis and homology sequence identification, showed that the five positive isolates were similar to the reference isolate. To the best of our knowledge, this is the first time that E. hormaechei has been isolated in cattle with BRD in Iraq. Because phenotype-based assays show limited accuracy to identify species, we recommend molecular and phylogenetic analysis be included in all similar studies in the future.

Mycoplasma hyopneumoniae and Actinobacillus pleuropneumoniae are causative agents of the porcine respiratory disease complex. However, information on the prevalence of these pathogens in wild boars is scarce. This study aimed to investigate the presence of antibodies to Mycoplasma hyopneumoniae and Actinobacillus pleuropneumoniae in wild boars in Serbia. In this study 253 serum samples from wild boars were tested for antibodies to Mycoplasma hyopneumoniae and Actinobacillus pleuropneumonia using the ELISA assay. The overall seroprevalence rates of Mycoplasma hyopneumoniae and Actinobacillus pleuropneumoniae were 4.2% and 56.9%, respectively. Antibodies to both pathogens were detected in 20 sera samples (7.9%). The prevalence of wild boars that were seropositive for Mycoplasma hyopneumoniae differed with age and ranged from 10.7% to 33.3%, and for Actinobacillus pleuropneumoniae, it ranged from 51.8% to 83.3%. Wild boars are hard to control and are considered a high-risk infection source for outdoor and backyard pigs and eventually for commercial indoor farms as well. Thus, the result of this first serosurvey in Serbia should raise awareness of the importance of wild boars as potential reservoirs of bacterial pathogens such as Mycoplasma hyopneumoniae and Actinobacillus pleuropneumoniae. Our data revealed the circulation of both pathogens in wild boars in Serbia, drawing attention to the potential health risk they present for domestic swine health.

Tibial torsion assessment is crucial for understanding deformities and malalignments that can lead to joint pathologies in dogs. Different methods such as radiography, computed tomography (CT), and three-dimensional (3D) volume-rendering techniques have been employed to measure tibial torsion. This study compared the accuracy and reliability of tibial torsion angle (TTa) measurements obtained using radiography and ultrasound tilting techniques against those obtained using the 3D volume-rendering method in small-to-medium-sized non-chondrodystrophic dogs. Seven dogs with 11 hind limbs were included in this study. Descriptive statistics revealed mean TTa values for radiography (1.6° ± 5.14°), ultrasound (2.92° ± 3.98°), CT (4.57° ± 3.44°), and 3D volume-rendering method (5.29° ± 3.30°). Intraclass correlation coefficient (ICC) analysis indicated excellent intra- and interobserver agreement between the radiography and ultrasound methods. Correlation analysis showed positive correlations between all the methods. These findings demonstrate that radiography and the ultrasound tilting technique are reliable alternatives for measuring TTa. Although slightly lower ICC values were observed than those of the 3D volume-rendering technique, the radiography and ultrasound methods still exhibited good to excellent reliability, suggesting that these alternative methods could be effective diagnostic tools for assessing TTa in clinical settings with high accuracy and reliability.

The breed can influence the results of haematological and biochemical blood tests, with sighthounds traditionally mentioned. It may also affect certain urinary parameters. This study aimed to compare urinary protein and creatinine concentrations and their ratio (UPC, urine protein to creatinine ratio) between sighthounds and non-sighthounds and to evaluate these parameters in various sighthound breeds. Urine samples from clinically healthy dogs were collected via normal voiding, representing both sighthound and non-sighthound breeds. The protein and creatinine concentrations in the urine samples were determined, and their ratio was subsequently calculated. A total of 191 urine samples from sighthounds and 90 urine samples from non-sighthound breeds used as a control group were evaluated in the study. In sighthounds, significantly lower urinary protein concentration (248.8 mg/l and 299.8 mg/l, respectively; P = 0.045) and significantly higher urinary creatinine concentration (23.0 mmol/l and 17.5 mmol/l, respectively; P = 0.000) and lower UPC values (0.13 and 0.18, respectively; P = 0.000) were observed in comparison to the entire control group. The UPC values were found to be significantly lower in Greyhounds and Spanish Greyhounds compared with non-sighthounds. Although statistically significant changes were identified, they are unlikely to be of great clinical importance.

Dog. Specifically created to save its master's life. - (The dog is the ideal) Friend of man, (because it is his devoted slave) (source: Gustave Flaubert, Dictionnaire des Idées Reçues). But is man the best friend of the dog? This question is legitimate when we consider living situations to which modern domestic dogs are exposed. They often do not satisfy basic animal needs. In this narrative review, the author revisits the history of the dog's presence alongside humans, in the light of current knowledge. The modern dog (breed standards and their interests in canine research) and its breeding strategy, including extreme breeding, will then be given particular attention. Dysfunctional human psychological processes will be explored to make it possible to grasp why the breeding of the modern dog is undergoing such a transformation. Finally, based on these factual and conceptual insights, suggestions to improve canine welfare will be proposed. To be effective, all these must be assessed against real-world conditions.

This study aimed to measure the whole blood viscosity (WBV) in racehorses using a new viscometer and establish reference values, as well as to investigate the correlation between the WBV and the haematological parameters and serum chemistry. WBV measurements were conducted on 51 Thoroughbred horses using a novel U-shaped scanning capillary-tube viscometer. The reference values for the WBV were determined at various shear rates ranging from 1 s-1 to 1 000 s-1. Correlation analyses were performed to examine the correlation between the WBV and the haematological and serum chemistry parameters. The findings provide valuable reference data for the WBV in Thoroughbred horses and enhance understanding of the relationship between the WBV and routine blood tests in equine health assessment.
