Impact of In-Feed versus In-Water Chlortetracycline and Tiamulin Administrations on Fecal Prevalence and Antimicrobial Susceptibilities of Campylobacter in a Population of Nursery Pigs

Microorganisms, 2023
Antimicrobial resistance (AMR) in bacteria is a major public health concern in the US and around the world. Campylobacter is an important foodborne pathogen that resides in the gut of pigs and is shed in feces, with the potential to be transmitted to ...

Chlortetracycline Residues in Eggs from Hens on Chlortetracycline-Supplemented Diets

Journal of AOAC INTERNATIONAL, 1972
Abstract Chlortetracycline was fed continuously to laying hens at levels of 0, 50, 100, 150, and 200 g/ton for a period of 4 months. Eggs from hens on the hasal ration showed a miniscule rate of positives, 2.1%; eggs from hens fed 50, 100, and 150 g/ton showed a positive presumptive rate of 58.3, 11.8, and 3.5% and a measurable residue ...
