Article Abstract
is one of the most common causes of mastitis worldwide. This study aimed to determine the prevalence and antimicrobial resistance (AMR) patterns of in mastitic milk samples collected from camel farms in Matrouh Governorate, Egypt. A total of 200 mastitic camel milk samples were evaluated for using both conventional culture-based and molecular-based methods. Antibiotic susceptibility testing of isolates was conducted using disc diffusion and agar dilution methods, with antibiotic resistance genes identified through polymerase chain reaction with specific primers. Out of samples tested, 60 (30.00%) were positive for . The isolates displayed the highest of resistance against piperacillin-tazobactam (55.00%) followed by trimethoprim- sulfamethoxazole (45.00%) and amoxicillin (40.00%). Half of the isolates were multidrug-resistant (MDR). The AMR genes included methicillin-resistant gene (), β-lactamase gene (), tetracycline resistance gene (), erythromycin resistance gene () and vancomycin resistant gene () were detected in 100%, 100%, 95.00%, 90.00% and 20.00% of the isolates, respectively. In conclusion, the presence of MDR as a cause of clinical camel mastitis is a significant veterinary and public health concern. These findings highlight the importance of proper antibiotic use in Egyptian camel farms and the need for molecular techniques to fully understand the genetic profile of antimicrobial-resistant isolates.

Background: Acinetobacter seifertii, a recently identified member of the Acinetobacter calcoaceticus-Acinetobacter baumannii (Acb) complex, has emerged as a cause of severe human infections. It is closely related to Acinetobacter nosocomialis, a major pathogen of the Acb complex. Here, we aimed to explore the clinical and molecular differences between these two species.

Potato early blight is a prevalent disease that significantly impacts potato cultivation. Pydiflumetofen, a new succinate dehydrogenase inhibitor developed by Syngenta, has been registered for use on multiple crops in China. However, its resistance risk and mechanisms in Alternaria tenuissima and Alternaria alternata are still poorly understood.

Essential oils (EOs) are a promising alternative to conventional pesticides, but some challenges like high volatility, poor water solubility, and rapid degradation limit their use in Integrated Pest Management (IPM). To overcome these limitations, this study aimed to develop garlic, eucalyptus, and clove EO-based nano-emulsions (EO-NEs) in a bait treatment format through the high-pressure microfluidization technique and investigated the biological activities against Ceratitis capitata. In addition, the adverse effects of the most promising nano-emulsion were evaluated towards a non-target parasitoid Anagaspis daci.

Sensitivity assessment of 300 Cercospora beticola isolates collected from North Greece revealed that 38 % of the population was highly resistant to at least one of the demethylase inhibitors (DMIs) difenoconazole, epoxiconazole and flutriafol. Resistance factors greater than 50, 100 and 100 were calculated for the most resistant C. beticola isolates to flutriafol, epoxiconazole and difenoconazole, respectively.
