Petting zoos transmit Virulent drug-resistant bacteria to visitors

Human infectious diseases :  Petting zoos transmit Virulent drug-resistant bacteria to visitors Petting zoos are a popular attraction around the world, allowing direct and indirect exposure of both children and adults to a diverse range of animal species. They are different from regular zoos because rather than visitors just looking at the animals, petting zoos are interactive with children visiting, holding and petting the animals. Extended spectrum beta-lactamase (ESBL) and AmpC-producing Enterobacteriaceae (AmpC-E), which are resistant to a number of commonly used antibiotics, have become a matter of great concern in both human and veterinary medicine, so understanding the likelihood of them colonizing the animals is critical to evaluating the risk that may be posed to visitors. The researchers did a survey across randomly chosen petting zoos geographically distributed throughout the world, taking samples of faecal matter as well as from the body surface (skin, fur, or feat

Drug-Resistance in Farm Animals Threatens Human Health

Antimicrobial Drug : Drug-Resistance in Farm Animals Threatens Human Health https://antimicrobial.vaccineconferences.com/speaker-guidelines.php In high-economic countries, where antimicrobial  have been used on farms since the 1950s, should support the transition to sustainable animal production in low & middle income countries for e.g. through a global fund to subsidize improvements in farm-level bio-safety  and bio-security , the authors advocate in the study. The Netherlands and Denmark have made a tremendous effort to reduce antimicrobial use. But these required investments in clean infrastructure and training of farmers to follow good farming practices and practicing good hygiene on the farm can reduce drug resistance in farm animals. A survey report has been done from 2000 and 2018 focusing specifically on common food-borne  pathogens, including  Escherichia coli, Campylobacter spp., non-typhoidal Salmonella,  and  Staphylococcus aureus. Trends and maps develope

The Bacterial Protein promoting Cancer

Viral Oncology :  The Bacterial Protein promoting Cancer DNA K, a protein of the bacterium mycoplasma, interferes with the mycoplasma-infected cell's ability to respond to and repair DNA damage, a known origin of cancer.  Little or no mycoplasma DnaK DNA sequences were found associated with the tumor, which was fully developed, suggesting a hit-and-run or hide mechanism of transformation, indicating that the damage is done early, but the protein may not be needed once the cancer cells are formed.                   Mycoplasmas are a family of bacteria that are associated with cancers, especially in people with HIV. Researchers utilized immune-compromised mice as a model for analyzing the effect of mycoplasma infection on the development of lymphoma. They compared how quickly non-infected immune-compromised mice developed lymphoma compared to mycoplasma-infected immune-compromised mice. The mice were infected with a strain of mycoplasma from an HIV patient. The researche
