The effect of probiotics, prebiotics and synbiotics on the restoration of the clinical state and balance of the intestinal microbiome after antibiotic therapy

The aim of the study was to establish the degree of influence of probiotics, prebiotics and synbiotics on the restoration of the clinical condition and balance of the intestinal microbiome of animals after antibiotic therapy. We studied 20 cats of different ages who underwent antibacterial therapy using the drug Ceftriaxone at a dose of 20.0 mg per kg of body weight 2 times a day, in the form of intramuscular injections, divided into four groups, each of which included five animals. The animals of the first group were prescribed the probiotic "Subtilis". The latter was administered orally in a dose of 8 drops, for 14 days. Animals of the second group were prescribed the probiotic "Subtilis" at the same dose and with the same multiplicity, as well as the prebiotic "Vetelact" in addition to it, at the rate of 0.1 ml per 1.0 kg of body weight daily for 14 days. The animals of the third group were administered orally the synbiotic "Evitalia-Vet" 1 tablet for 14 days. The fourth group was a control group. The animals included in it were under observation and did not receive any drugs. It was found that the restoration of the clinical state and balance of the intestinal microbiome after antibiotic therapy was most intensive in animals receiving the probiotic "Subtilis" and the prebiotic "Vetelact". Under the influence of these drugs, at the end of treatment, the level of hemoglobin, erythrocytes and hematocrit decreased by 22.0%, 19.0% and 15.7%, respectively, in animals receiving them, compared with the indicators before it began. Also, in comparison with other groups, animals receiving the probiotic "Subtilis" and the prebiotic "Vetelact" showed a more pronounced decrease in the level of urea and total protein in blood serum, while the number of lactobacilli at the end of treatment was 42.0% higher, and the population of E. coli decreased by 37.0%, in comparison with control. Thus, the simultaneous administration of probiotics and prebiotics to animals after undergoing antibiotic therapy gives the most effective result, manifested in the accelerated restoration of their clinical condition and the balance of the intestinal microbiome.
