Due to the global decline of bacterial antimicrobial sensitivity, international organizations such as Word Health Organization, Food and Agriculture Organization, and World Organization for Animal Health consider it necessary to implement an integrative approach to the fight against antibiotic resistance in the light of the One Health concept. The purpose of the study was to investigate the degree of interchangeability of the antibiotic resistance of the isolated microbiome from wild boars and their living environment. The samples (n=24) were collected from two hunting funds in Covasna and Cluj counties. The identification of microorganisms was performed using the Vitek®2 System and, subsequently, their susceptibility was evaluated using the agar diffusion method. The isolated strains were identified as Pseudomonas spp., Pseudomonas aeruginosa, Pseudomonas luteola, Brevibacterium spp., Aerococcus viridans, Aeromonas sobria, Campylobacter coli, Campylobacter lari, Staphylococcus aureus, and Streptococcus suis. The highest multiple antibiotic resistance index (MAR 0.666) was identified in strains isolated from Cluj County, while the lowest (MAR 0.111) was obtained in strains isolated from Covasna County. The results of this study further acknowledge the bacterial resistance in wildlife.

Mastitis remains a major challenge for the global dairy industry, despite the widespread implementation of control strategies. Escherichia coli and Streptococcus uberis are the most common agents of mastitis in cattle and a significant problem for the dairy industry. The aim of this study was to establish the prevalence of bacteria involved in mastitis of dairy cows and to establish the antibiotic resistance profile, which frequently complicates the therapy. In order to achieve these objectives, samples (n=25) were collected from cattle diagnosed with clinical mastitis and subclinical mastitis detected by biochemical assays. The samples were processed by standard microbiological methods and the results indicated an increased prevalence of Staphylococcus spp. and of microorganisms of the Enterobacteriaceae family. Isolated bacterial strains have shown significant resistance to antibiotics, especially to amoxicillin, while ciprofloxacin has proven the most effective. Thus, the early detection and correct treatment of clinical and subclinical mastitis is an important challenge for the economy and for the public health.

Carcinomatous mastitis or the inflammatory mammary carcinoma is a malignant entity described in human, dog and cat clinical oncology; it is characterized by a sudden onset, edema, erythema, peau d’orange, hardening and increased local temperature of the mammary gland, with or without the presence of mammary nodules. Blockage of superficial lymphatics with neoplastic cells is the cause of severe edema in the region. This type of cancer is characterized by an extremely fast rate of growth, development and invasiveness. Tumor cells break the basement membrane and invade regional lymphatic vessels and satellites lymph nodes. Cutaneous T-cell lymphoma in the dog is a rare neoplastic condition with unknown etiology. The reaction at dermis level is characterized by infiltration of neoplastic T lymphocytes with a specific tropism for the epidermis and the ancillary structures. The abnormal division of lymphocytes present plaques or other lesions within the skin. It often involves enlarged satellite lymphnodes, edema, erythema and hardening of the malignant nodules. The link between the immune role of the T-cells and the fulminant inflammatory reaction of the carcinomatous mastitis, frameable in the category of autoimmune diseases, is just one of the puzzles researchers are trying to solve in order to prove the connections between the two neoplasias. One of the pieces is the role of cytokines, having value both in canine inflammatory mammary cancer and T-cell lymphoma. Their purpose of these small proteins that act as cell-to-cell messengers and play an important role within the immune system by stimulating or inhibiting cells in response to a range of stresses has been evaluated due to it's valuable contribution as diagnostic biomarker, biologic predictive marker and the therapeutic significance. The purpose of this study was to characterize the two malignant pathologies clinically, histopathologically and regarding response to treatment in order to identify common ground. Following the information obtained from the studies considered for this article, supplemented with personal case studies, the presence of a mixed neoplasm in the form of an undifferentiated carcinoma interspersed with T lymphoblasts is suspected.

A cross-breed female cat was presented with clinical signs of abdominal pain, paralysis of both hind limbs, tachycardia, tachypnea and bilateral absence of the femoral pulse. Necropsy confirmed an aortic thrombus at 2 cm above the adrenal glands, the heart with left atrial dilation and hypertrophied left ventricle, multiple bilateral kidney cysts and ectopic thyroid tissue. Histopathological examination reveals the kidney with multiple cysts, diffuse loss of renal structural details without inflammatory cells, hypertrophic cardiomyopathy, and no ectopic thyroid tissue changes. This communication describes a case of aortic thromboembolism associated with hypertrophic cardiomyopathy due to autosomal dominant polycystic kidney disease and ectopic thyroid tissue.

The aim of this systematic review is to examine the effects of different anesthetic drugs and protocols on hepatic functions. The liver is a very important organ since it is directly involved in biotransformation of the drugs used in anesthesia. Comprehensive understanding of anesthetic drugs and their effects on hepatic functions remains fundamental to a successful anesthesia. Understanding the connections that exist between anesthetic drugs and liver function remains essential for a safe anesthesia both during the surgery and in the post-operative period. Almost all anesthetic drugs depend on hepatic biotransformation into their metabolites that can be transported and excreted by the kidneys. If the liver enzymes are altered, the biotransformation of the drugs will be decreased and the recovery from the anesthesia prolonged.

In micro-farms or households where there are no veterinary health problems, it is recommended that the metabolic tests should be performed during periods when the metabolic strain is more intense, as they represent a method of monitoring the animals’ health, especially during critical periods. A total of 52 cattle were divided into 5 groups according to their physiological condition, age category and health status. Total serum protein showed significantly higher values (p<0.05) in adult animals compared to the other age groups. Calves with digestive disorders had moderate hypoproteinemia, as a result of consecutive protein depletion, malabsorption and maldigestion syndrome from gastroenteritis, especially in the case of chronic ones, accompanied by an intake and improper use of ration proteins, respectively by mass elimination following intestinal protein loss. The mean blood glucose values did not differ significantly (p>0.05), the unitary response of the studied cattle categories being remarked. In the case of the mineral profile, the variations that appeared are mainly due to the different nutritional support, specific to the two breeding systems, but also to the different pathological conditions detected.

As it is known, taxonomy is one of the most dynamic aspects of biology. Ever since Antiquity, throughout the linnaen and post-linnaen period and until the new cladistics era, all branches of the phylogenetic tree were subject to plenty of modifications. The Equus genus was no exception, one of the most important evolutionary transformations being the reduction of the number of fingers in this genus, criterion considered crucial for correctly placing a species. Numerical reduction is also accompanied by a reorganisation of vascular and nervous trajectories. Based on autopodial parts of 10 individuals, this study aims to identify details and potentially individual variants which may complete existing literature data and which will represent additional arguments to the taxonomic classification of the species. The main objectives of this study were represented by the description of individual variants and clarifying of data regarding anatomical terminology, hoping that once achieved the results will aid veterinary research and practice.

Otitis externa is a common condition in dog with a multifactorial etiopathogenesis including primary factors along with predisposing and perpetuating factors. Therefore, a successfull therapy of otitis externa should target the identification and correction of primary causes as possible as, not only the elimination of secondary infections. In practice, ear swab cytology is considered to be the best choice for the diagnosis and initial treatment of otitis, recommended to be repeated for the therapy evaluation or adjustment. Our study included 20 dogs exhibiting various clinical forms of otitis externa, from mild acute to severe chronic otitis with often associated pruritus and smelly discharge, came to be investigated at the Dermatology Service of Veterinary Medicine Faculty from Bucharest. Cytology showed variable proportion of desquamated keratinocytes, lipid droplets and debris of cerumen, leukocytes, especially degenerated neutrophils and free or phagocytized bacterial and yeast elements. The patients have been reevaluated at every 2-3 weeks after initiating therapy and finally, clinical signs resolution together with decreased cellularity in cytological preps were considered good indicators for patient recovery.

The essential conditions for a successful osseointegration of dental implants are bone support and the bone-implant contact area. The aim of this study was to evaluate an innovative treatment in sheep periimplantitis, carried out in three stages: preparation of the implant bed, fixation of the implants and induction of periimplantitis. In phase I was verified the process of osteogenesis following the premolars extraction. Ten sheep were prepared by putting them on a diet before surgery and by giving them antibiotics. Under inhalatory anesthesia, a total of 8 premolars/animal were extracted by dislocating each one, followed by rotational movements in the perpendicular axis and straight traction to the outside. A hemostatic sponge was inserted into the tooth alveoli and the gum was sutured. After extraction, the sheep received anti-inflammatory and antibiotic treatment. During the monitoring period, the local and general clinical conditions were monitored, and bone regeneration was assessed by Computer Tomography. Clinically, the evolution was favorable, with no signs of discomfort, with gum scarring in 7 days and weight gain of 24-41%. Imagistic, a degree of bone atrophy within physiological limits could be observed, and the density of the neoformation bone tissue showed an optimal regeneration. Through the approached technique we provided a favorable environment for performing the next stages of the study, the osteogenesis process being validated both clinically and paraclinical. We also propose this method for flocks of sheep with dental diseases.

The paper aimed to present the correlations between the freshness indicators (pH, TVB-N) and water content, phosphorus content and humidity, protein content and TVB-N (mg %) in wild Anglerfish/ Monkfish captured from the North Sea and Atlantic Ocean during naval expeditions aboard the research ship Walther Herwig IIIrd. It is based on the research data obtained at Max Rubner Institute Department of Safety and Quality of Milk and Fish Products Hamburg between 2013 and 2014. The processed data were the following indicators: pH, TVB-N, phosphates content, percent of water, salt, protein, fat and ashes. Correlations were made using chi square test. Angler- and Monkfish (Lophius spp.) samples analysed (n = 77), presented a reasonable positive correlation (R2 = 0.44) between the pH values and the percentage of water, a very weak positive correlation (R2 = 0.1) between TVB-N and protein, a high negative correlation (R2 = - 0.7018) between the phosphate and water content and a strong negative correlation (R2 = - 0.7961) between the protein and the water content.
