In 1928, microbiologist Alexander Fleming’s discovery of penicillin was hailed as a scientific breakthrough. In the nearly 100 years since then, scientists have discovered numerous other antibiotics that have saved billions of lives. However, bacteria have become increasingly resistant to these treatments. There are two reasons for this: the overuse and misuse of antibiotics by humans, and the introduction of antibiotics to agriculture.

Antibiotics in feed select for resistant strains and is thus a threat to human health. In this study, the effect of a multi-strain probiotic and antibiotics on the growth and health of broilers was studied…
Newly hatched broiler chickens are the most susceptible to Salmonella infections, especially during the first 24 h. At this age, the gut microbiome is not fully developed and offers little protection in the form of competitive exclusion.
Bacteria isolated from different segments of the gastro-intestinal tract (GIT) of healthy free-range broilers were screened for probiotic properties. Six strains were selected and identified as Lactobacillus gallinarum, Lactobacillus johnsonii, Lactobacillus salivarius, Lactobacillus crispatus, Enterococcus faecalis and Bacillus amyloliquifaciens.
