Abstract

Bacillus megaterium is a bacteria that causes human infections, causing keratitis, skin infections, brain abscesses and tissue infections. Treatment often uses chemical antibiotics. However, long-term antibiotics can cause new health problems such as resistance. Therefore, antibacterial ingredients are needed that can not only inhibit the growth of bacteria but also do not have a negative impact on health such as honey. Honey is thick, it can cure various diseases such as gastrointestinal, stomach, skin diseases, acute respiratory infections and coughs. This research aims to determine the ability of Sumbawa white honey as an antibacterial against B. megaterium. The method used in this research is paper disc diffusion. There were five treatments used in this study, between 100%, 75% and 25% honey concentrations, DMSO negative control and chloramphenicol positive control with five replications each. The results of the antibacterial activity test showed that the 100% concentration had an inhibitory zone diameter of 2.59 mm, then the 75% concentration was 1.46 while the 25% concentration was 0 mm. When compared with positive control, white honey was lower antibacterial. If it is in the white honey category, the inhibition zone category is included in the lower category.

Abstract

Chicken meat and eggs are widely consumed sources of protein, increasing consumer demand and leading to the use of antibiotics as prophylaxis and therapeutics. The purpose of this narrative review is to describe the colonization of chicken parts and organs and summarize the resistance genes in chickens reported from 2015 to 2026. The method used a systematic literature review with a narrative review. This review focuses on four main bacteria: Escherichia coli, Salmonella spp., Campylobacter spp., and Enterococcus spp. The results showed that almost all chicken organs were colonized by bacteria carrying various antibiotic resistance genes. These resistance genes included fluoroquinolones (gyrA, gyrB), tetracyclines (tetA, tetB, tetO, tetM, tetL), β-lactams (blaTEM, blaSHV, blaCTX-M, blaCMY, blaOXA-61), aminoglycosides (aac, aad, aph, strA/B), and sulfonamides (sul1, sul2, sul3). The presence of multidrug efflux pump genes (cmeB, cmeG) in Campylobacter spp. further highlights the increasing prevalence of multidrug resistance. Colonization of antibiotic-resistant pathogenic bacteria with resistance genes has been found in vital organs of chickens. These findings highlight the importance of molecular surveillance and integrated One Health strategies to reduce the spread of AMR.
