The use of metals as feed supplement has been recognized as a potential driver for co-selection of methicillin-resistant Staphylococcus aureus in pigs. However, the prevalence of these determinants in methicillin-resistant coagulase-negative staphylococci (MRCoNS) is largely unknown. In this study, a collection of 130 MRCoNS from pigs and veal calves were investigated for the presence of metal-resistance genes (czrC, copB, cadD, arsA) associated to SCCmec. Near half of the isolates carried metal resistance genes (czrC 5.4%, copB 38.5%, cadD 7.7%, arsA 26.2%) regardless of their SCCmec type. The increased use of metals in livestock animals, especially zinc in pigs in several European countries may co-select for methicillin-resistance in several staphylococcal species.

Comparison of the Staphylococcal Chromosome Cassette (SCC) mec in Methicillin-Resistant Staphylococcus aureus (MRSA) and Non-aureus Staphylococci (MRNAS) from Animals and Humans

Summary: This study identified and compared the SCCmec types of MRSA or MRNAS isolated from different countries in various animal species and humans. The results confirmed a high prevalence of SCCmec types IV and V in LA-MRS and CA-MRS in Belgium, highlighting the possible public health hazard and absence of SCCmec in some MRNAS.

Summary: Infections caused by Staphylococcus aureus are a leading cause of mortality. Resistance to traditional antibiotics, including beta-lactams, makes treating these infections difficult. Mutations in the gdpP gene have been found to increase antibiotic tolerance and promote the development of beta-lactam resistance in S. aureus.

The Endometrial Microbiota-16S rRNA Gene Sequence Signatures in Healthy, Pregnant and Endometritis Dairy Cows

Summary: In order to achieve a consistent diagnosis, treatment, and prevention of uterine diseases in dairy cattle, researchers have focused on identifying the bacteria present in the uterus, known as the uterine microbiota. A study analyzed the uterine microbiota from healthy, pregnant, and diseased cows and found that the bacterial composition was more similar in healthy and pregnant cows compared to diseased animals. Endometritis, a major cause of infertility in dairy cows, results in significant economic losses. The study explored the endometrial microbiota and found significant differences in species diversity between healthy and diseased cows.

Summary: Antimicrobial resistance is a global threat to human and animal health, with livestock potentially having a low contribution to the spread of resistance. Strategies targeting the reduction of all antimicrobials and implementation of the 'One Health' approach are recommended to effectively combat antimicrobial resistance.

Expression of sperm microRNAs related to bull fertility: A systematic review

Lucas Petitemberte de Souza, William Borges Domingues, Eduardo Bierhals Blodorn, Leandro da Silva Nunes, Hadassa Gabriela Ortiz, Eliza Rossi Komninou, Vinicius Farias Campos

Summary: This study performed a systematic review of the differential expression of sperm microRNAs in bulls related to fertility. A total of 182 unique differentially expressed miRNAs were identified, among which 49 miRNAs were found in common between at least two studies. The results suggest that miRNAs such as miR-10a, -10b, -103, -15b, -122, -125b, -126-5p, -151-5p, -193a-5p, -196a, -27a-5p, and -99b may serve as potential universal biomarkers for assessing the reproductive potential of males.

Prevalence and risk factors for hair loss in outdoor-wintered beef cattle under cold weather conditions

Wonhee Cha, Katinca Fungbrant, Giulio Grandi, Ylva Persson

Summary: This study investigated the prevalence and development of hair loss in outdoor cattle in Sweden. It found a relatively high hair loss rate, with the occurrence of hair loss increasing over time during winters, suggesting a contagious etiology. The study also identified preventative delousing before November, keeping animals clean, and maintaining small group sizes as effective measures to reduce the risk of hair loss, while older age and access to bedding materials increased the risk.

Summary: This study used infrared thermography (IRT) to identify mastitis in Sahiwal cows. The results showed significant differences in the mean values of udder and teat surface temperature between healthy, subclinical mastitis (SCM), and clinical mastitis (CM) cases during different seasons. IRT is an efficient tool for the early identification of subclinical mastitis.

Plasma disposition and faecal excretion of eprinomectin following subcutaneous administration in Saanen and Alpine goats

Zeynep Ozdemir Kutahya, Busra Aslan Akyol, Kubra Deliklitas, Cengiz Gokbulut

Summary: In this study, the pharmacokinetic behavior of Eprinomectin was studied in two different goat breeds. The results showed no significant differences in plasma concentration between the breeds, but the clearance from the body may vary. High concentration of Eprinomectin in feces is beneficial against gastrointestinal parasites but poses an ecotoxicological risk to the environment.

Impaired efficacy of fenbendazole and ivermectin against intestinal nematodes in adult horses in Iran

Mohammad Ashrafzadeh-Shiraz, Mousa Tavassoli, Bahram Dalir-Naghadeh, Alireza Sazmand

Summary: This study evaluated the efficacy of fenbendazole and ivermectin on strongyles and Parascaris sp. infecting adult riding horses in different regions of Iran. The results demonstrated varying degrees of resistance of these parasites to both anthelminthics. It emphasizes the urgency of educating horse owners about the importance of a test-and-treatment strategy and suggests evaluating the efficacy of different anthelminthics to choose the most effective treatment in each region.
