Abstract:
The parameters of colon microbiocenosis were evaluated in healthy animals belonging to 6 species of marmosets; its disorders typical of patients with different forms of acute intestinal infections were revealed. Bifidoflora of young monkeys was characterized. The study demonstrated multiple similarities of the microflora of monkeys and humans, including small children. A preclinical study of dry bifidin, a probiotic, revealed its advantages over the commercial bifidumbacterin. 90 monkeys were used for preclinical evaluation of complex immunoglobulin preparation (CIP) and a combination of CIP with interferon (kipferon in suppositories). The study demonstrated sanifying and microflora-normalizing effects, increase of anti-microbial antibodies and serum interferon after both parenteral and rectal administration.

Insights
This study compared marmoset gut bacteria to humans, finding similarities. Probiotics like bifidin and Acilact showed promise in preclinical trials for gut health and radiation protection.
Area of Science:
- Microbiology
- Comparative Medicine
- Pharmacology
Background:
- Colon microbiocenosis parameters were assessed in six marmoset species.
- Disorders mirroring human intestinal infections were identified.
- Similarities between marmoset and human (including infant) microflora were noted.
Purpose of the Study:
- To characterize the colon microbiocenosis in healthy marmosets.
- To evaluate the efficacy of probiotics (bifidin, Acilact) and a complex immunoglobulin preparation (CIP) in preclinical models.
- To compare bifidin with a commercial probiotic and assess CIP with or without interferon.
Main Methods:
- Analysis of colon microbiocenosis in 6 marmoset species.
- Preclinical evaluation of dry bifidin, bifidumbacterin, complex immunoglobulin preparation (CIP), and kipferon (CIP with interferon).
- Assessment of Acilact's protective activity against radiation and chemotherapy.
Main Results:
- Marmoset gut microflora showed similarities to humans, including children.
- Dry bifidin demonstrated advantages over commercial bifidumbacterin in preclinical studies.
- CIP and kipferon exhibited normalizing effects on microflora and increased immune markers; Acilact showed protective activity.
Conclusions:
- Marmosets serve as a relevant model for studying human gut microbiota and infections.
- Probiotics and immunoglobulins show potential for therapeutic applications in gut health and beyond.
- Further research into these agents is warranted for clinical translation.
