The purpose of this study was to determine if the probiotic bacterium, Lactobacillus rhamnosus, generates compounds that affect the sporulation of the oocysts of three species of Eimeria using an in vitro assay. In addition, anticoccidial effects of L. rhamnosus cell-free supernatant (CFS)-based diets were evaluated in chickens following experimental infection with Eimeria tenella and the antic...

Anticoccidial effects of the Plantago asiatica extract (PAE) were evaluated in chickens following oral infection with Eimeria (E.) tenella. This study was conducted on the 3-day-old chickens (n=30). Those animals were divided with 3 groups; PAE 0.1% treated/infected (n=10), PAE untreated/infected (n=10) and non-infected control (n=10). Chickens were fed a standard diet supplemented with or with...

In order to investigate cecal coccidiosis in broilers fed zeolite mixtures, two experiments were performed. The first was carried out in vitro, where the concentration of anticoccidial medicine not adsorbed by zeolites was determined by a spectrophotometric method. In the second experiment 100 one-day old broilers were divided into two groups that were fed with mixed feed containing the anticoc...

Interest in polyether antibiotics has remained at a high level for over 20 years, owing largely to the commercial importance of this class of drugs in veterinary medicine. For example, monensin1*, lasalocid1} and salmomycin2) are marketed as anticoccidial agents for poultry, and are used as growth permittants in cattle or swine. Narasin1} and maduramicin3) are also used as anticoccidial agents....

A new polyether antibiotic, abierixin, was found in the mycelium of a culture broth of nigericin-producing Streptomyces albus NRRL B-1865. Abierixin was extracted with organic solvents and purified by column chromatography and HPLC. The structure of abierixin was determined by FAB/MS/MS and CI/MS/MS and 1H and 13C NMR spectrometries. Abierixin exhibited weak antimicrobial and ionophorous activi...
