Antimicrobials in poultry
Antimicrobial agents are essential tools for treating and controlling bacterial infections in poultry production. Veterinarians have a huge responsibility when using antimicrobials in poultry producing meat and eggs for human consumption. The term ‘judicious use’ of antimicrobials implies the optimal selection of drug, dose and duration of antimicrobial treatment, along with a reduction in inappropriate and excessive use as a means of slowing the emergence of antimicrobial resistance. The proper use of antimicrobials depends on the knowledge of interrelationships between bacteria, antimicrobial, host and consumer. The antimicrobial groups most commonly used in poultry are the betalactams, polypeptides, aminoglycosides and aminocyclitols, macrolides and lincosamides, florfenicol, tetracyclines, sulphonamides, quinolones and fluoroquinolones and ionophores.
Introduction Infectious bronchitis, newcastle disease, infectious laryngotracheitis, avian influenza, and pneumovirus are the viruses that more frequently affect the respiratory tract of chickens. Because of the tendency to change its antigenic properties, viral diseases are predominantly present in most poultry producing areas of the world. New serotypes and variant strains of respiratory viruses are reported in several countries. Current commercially available vaccines do not...

Additional research has shown that using DHP in single stage incubators can achieve the same level of microbial reduction on eggshells as pre-fogging eggs with formaldehyde prior to set. The next step in the research process, and thus the purpose of this experiment, was to directly compare dry hydrogen peroxide to the traditional method of using formaldehyde for microbial reduction. The trial is set in a commercial broiler hatchery, where DHP units were installed throughout the egg room,...

We export veterinary APIs and vitamins and have followed the market trends of Chinese products for many years. Today I will briefly review the situation for florfenicol.
In 2022, florfenicol market prices fell from a high level, with ups and downs during the year and overall weakness throughout the year. From January to April, the florfenicol price fell off a cliff from the highest point of the year and then entered a phase of oscillation at low level. In December, the prices went...

INTRODUCTION Salmonella has been linked to numerous foodborne illnesses from consumption of poultry products. The FoodNet preliminary data for 2016-2019 identified 25,866 infections, 6,164 hospitalizations and 122 deaths due to foodborne illnesses in United States of which Salmonella contribute about 17.1% of total foodborne infections (Tack et al., 2020; Vaddu et al., 2020). They also reported 5 most common Salmonella serotypes in the US - Enteritidis, Typhimurium, Newport,...

A veterinarian’s perspective on AMR and sustainable animal agriculture One of the landmark scientific achievements of the 20th century has been the discovery of antibiotics. Antibiotics have revolutionized healthcare and have helped healthcare professionals save precious human and animal lives for centuries. However, antibiotics have now become victims of their own success. Due to their non-judicious and blind use, we now face a widespread...

INTRODUCTION Poultry and poultry products represent a popular choice of protein in the United States, with increasingly high consumption rates over the past years (Zhang et al., 2018). Poultry meat has surpassed both pork and beef in per capita consumption in the United States (USDA Economic Research Service, 2020). With this increased consumption of poultry and poultry products, there is a significant concern for contamination, thus impacting public health. Salmonella and...
