Kanamycin, penicillin, and streptomycin were injected individually into air cells of newly set chicken and turkey hatching eggs, and assay was made throughout the incubation period to determine the location, potency, and duration of efficacy. By 24 hours, each antibiotic had diffused throughout the albumen. By six days, penicillin residues could not be detected, whereas kanamycin or streptomyci...

in poultry breeding, use of any antibiotics as a food additive that promotes growth, prevention or treatment of infectious diseases will increase the chance of drug residues in poultry meat products. in this study, the presence of different antibiotics in ten broiler flocks, which were later transported to mashhad poultry abattoir have been investigated, using four plate test (fpt) method. a to...

Antibiotics are used by the veterinarians and poultry industry to enhance growth rates, health of the birds, feed efficiency, egg production and for therapeutic reasons to reduce the incidence of poultry diseases. Antibiotics had been used in poultry production for both therapeutic and prophylactic purposes. Most poultry farmers in Nigeria have employed the use of various antibiotics with or wi...

Antibiotic use in food-producing animals has considerable impact on public health, especially with respect to the development and spread of antibiotic resistance. Pigs represent one of the main species in which antibiotics are frequently used for different purposes. Surveillance of antibiotic consumption and dose appropriateness, through novel approaches based on defined daily doses, is strongl...

The highest frequency is on day 1 (after treatment) after which it gradually decreases. It should be noted that no antibiotic residues were detected in the collected milk samples prior to treatment. Antibiotic may of recently calved animals due intramammary treatments during dry period (chronic mastitis). If treatment less than 15 days until calving, detecting calving high. As noted, there two ...

Antibiotic resistance and associated genes are ubiquitous and ancient, with most genes that encode resistance in human pathogens having originated in bacteria from the natural environment (eg, β-lactamases and fluoroquinolones resistance genes, such as qnr). The rapid evolution and spread of "new" antibiotic resistance genes has been enhanced by modern human activity and its influence on the en...

Abstract We tested two summer protocols for oxytetracycline (OTC) administration on beehives to evaluate: toxicity the bees, residues in honey and presence of genes encoding OTC antibiotic resistance bacteria isolated from gut adult bees. In July 2020, eighteen healthy colonies were divided into three groups. Two treatment - long short, devised, one group was left untreated. did not detect any ...

Antibiotic treatment of tuberculosis (TB) is complex, lengthy, and can be associated with various adverse effects. As a result, patient compliance often poor, thus further enhancing the risk selecting multi-drug resistant bacteria. Macrophage mannose receptor (MMR)-positive alveolar macrophages (AM) constitute niche in which Mycobacterium replicates survives. Therefore, we encapsulated levoflox...
