Summary: In this study, the virucidal efficacy of sodium hypochlorite (NaOCl) and peracetic acid (PAA) against SARS-CoV-2 was investigated. The results showed that 50 ppm of NaOCl and PAA were effective in the absence of soil load, but 200 ppm were required in the presence of soil load. Furthermore, 200 ppm of NaOCl and PAA for 1 min were not effective against SARS-CoV-2 on stainless steel and high-density polyethylene surfaces, while 200 ppm PAA for 10 min was effective, and 1000 ppm NaOCl for 10 min was required.

Summary: The study found that antibiotic residues and antibiotic resistant bacteria are more prevalent in fattening calf slurry than in beef cattle farmyard manure used for agricultural field fertilization. Specifically, higher concentrations of antibiotics like oxytetracycline, ciprofloxacin, and enrofloxacin were detected in fattening calf slurry samples. Additionally, a greater percentage of E. coli isolates from fattening calf slurry were resistant to multiple antibiotics compared to those from beef cattle farmyard manure.

Summary: The semi-permeable membrane composting was effective in reducing the levels of mcr-1 and blaNDM-1 in copper-contaminated poultry manure. Although mcr-1 levels decreased significantly in the low copper treatment group, blaNDM-1 levels increased after composting, especially in the copper addition groups. The relative abundance of mcr-1 and blaNDM-1 varied significantly in different pile layers of copper treatment groups.

Summary: This study investigated the survival of Salmonella Typhimurium in broiler carcasses exposed to ozone, lactic acid, sodium hypochlorite, and levulinic acid. Results showed that all treatments were effective in inactivating S. Typhimurium, with 3% levulinic acid solution being the most effective. Ozone treatment showed a lower logarithmic decrease in S. Typhimurium numbers compared to other treatments.

Summary: This study aimed to evaluate the effects of 3 different ozone irrigation protocols on Enterococcus faecalis biofilm. The results showed that there was no significant difference in bacterial count among the different protocols, but all protocols resulted in a reduction of over 99% in Enterococcus faecalis count. The ozone protocols assessed were found to be similar in reducing the bacteria.

Summary: There is currently no perfect test for determining herd-level status for Salmonella Dublin in dairy cattle herds. This study evaluated different testing scenarios using repeated measurements to establish the S. Dublin herd status, and found that a diagnostic strategy consisting of two visits at a 6-month interval could confidently rule-out S. Dublin infection in herds with a low prevalence of disease.

Summary: This study evaluated a new approach called greenponics, using undecomposed plant biomass as both the growing substrate and fertilizer, for growing cherry tomatoes. The results showed that greenponics with grass clippings as the only source of fertilizer could be a potential alternative for growing cherry tomatoes in pots.

Summary: The study demonstrated the effectiveness of the plastic-wrapped composting system in disposing swine mortalities and confirmed its ability to eliminate the spread of airborne pathogens through aeration ducts. Different cover materials and aeration methods affected the system's performance, but after a 7-week composting period, all pathogens were inactivated.

Summary: This study evaluated the ameliorative effect of fucoidan on AFB(1)-induced hepatorenal toxicity in rats. The results suggest that fucoidan alleviates cell damage and oxidative stress induced by AFB(1), possibly due to its antioxidant and anti-apoptotic activities.

Summary: By using the CART data mining model, the seroprevalence of contagious caprine pleuropneumonia in goats and sheep was determined along with the associated risk factors. Older animals, flock size >= 200, and communal feeding and watering were identified as key factors for the disease. The CART model showed higher accuracy than traditional logistic regression, highlighting flock size as the most important risk factor.

Summary: This study investigated the environmental presence of SARS-CoV-2 in Midwestern meatpacking plants, finding 42 positive surface samples in employee common areas while no virus was detected in air samples. Case positive data showed that environmental sampling is a lagging indicator of community and plant infection.

Summary: A study conducted in the Nile Delta of Egypt found that horses older than 15 years, stallions, and horses of mixed breeds are more likely to be infected with West Nile virus. Intensive surveillance and effective control strategies are recommended for stallions, mixed-breed horses aged over 15 years.

Summary: Machine learning approaches were used to determine the seroprevalence of the contagious zoonotic disease, Brucellosis, and to assess the associated risk factors in densely populated cattle areas in Egypt. Logistic regression and Classification and Regression Tree (CART) data-mining analysis were compared, with CART showing higher accuracy in identifying risk factors. The study found that larger herd size, history of abortion, and poor post-calving hygiene were important risk factors for Brucella infection.

Summary: This study evaluated the ovulatory response of mares to deslorelin acetate during the fall and their response to PGF2 alpha 8 days post-ovulation. The results showed that mares displayed a highly efficacious response to deslorelin acetate and apparently normal luteal function during the fall, despite lower edema scores in late fall.

Summary: This study investigated the prevalence of B. vogeli in dogs from Egypt using PCR assay and evaluated the associated risk factors. The prevalence rate of B. vogeli was 5.1%, with tick infestation and the type of dog shelter floor identified as potential risk factors. Phylogenetic analysis revealed the Egyptian isolate to be grouped with isolates from Japan, Venezuela, and Paraguay. The findings contribute to the understanding of canine babesiosis epidemiology and disease control in companion dogs.

Summary: The objective of this study was to evaluate the diagnostic accuracy of three different tests for detecting Mycobacterium avium subsp. paratuberculosis (MAP) infections in sheep in Egypt. The study found that ELISA had the highest sensitivity among the tests and comparable specificity to the other two tests. ELISA could be a promising alternative for detecting MAP in sheep due to its high sensitivity, cost-effectiveness, and shorter laboratory processing time.

Summary: This study utilizes a simplified gravity model to understand the effects of standstill orders on individual states. The analysis determined that both the population size and location of the closure affected the observed trade patterns. These findings suggest that using a regional stop movement order may complicate disease introduction preparation.
