Abstract

Insights

A multispecies probiotic, Ecologic 641, effectively inhibits pathogens causing pancreatic necrosis. Its antimicrobial properties, mainly from organic acids, are crucial for treating severe acute pancreatitis.

Area of Science:

  • Microbiology
  • Gastroenterology
  • Probiotic Research

Background:

  • Severe acute pancreatitis (SAP) can lead to complications like bacterial overgrowth and infected pancreatic necrosis.
  • Probiotic prophylaxis is explored for preventing these SAP complications, but their antimicrobial activity requires further investigation.

Purpose of the Study:

  • To evaluate the antimicrobial properties of a specific multispecies probiotic product (Ecologic 641).
  • To determine the efficacy of Ecologic 641 against pathogens commonly found in infected pancreatic necrosis.

Main Methods:

  • The well-diffusion method was employed to assess antimicrobial activity.
  • Ecologic 641 and its individual strains were tested against pathogenic bacteria isolated from infected pancreatic necrosis.
  • Probiotic-free supernatants were used as controls.

Main Results:

  • Individual probiotic strains showed partial inhibition of pathogen growth.
  • The multispecies preparation, Ecologic 641, demonstrated inhibition against all tested pathogenic isolates.
  • Probiotic-free supernatants did not inhibit pathogen growth, indicating the probiotic's direct effect.

Conclusions:

  • Ecologic 641 exhibits broad-spectrum antimicrobial activity against diverse pathogens implicated in infected pancreatic necrosis.
  • The production of organic acids is a key mechanism behind Ecologic 641's antimicrobial effects.
  • Ecologic 641 is under investigation in a large-scale clinical trial for patients with predicted severe acute pancreatitis.

Antimicrobial Proteins01:23

Antimicrobial Proteins

Antimicrobial proteins are important components of the immune system. They aid the body in combating pathogens by either killing them directly or hindering their replication processes. Four main types of antimicrobial substances are interferons, the complement system, iron-binding proteins, and antimicrobial proteins.
Interferons
Interferons (IFNs) are proteins produced by lymphocytes, macrophages, and fibroblasts infected with viruses. While IFNs cannot prevent viruses from entering and...

Biological Methods for Microbial Control

Biological agents offer an effective means of controlling microbial growth by leveraging natural processes like predation, competition, and the secretion of antimicrobial substances.Predatory bacteria such as Bdellovibrio species target and kill pathogens like Salmonella and E. coli. They are widely used in poultry farms to control infections. Myxococcus species help combat plant-pathogenic fungi. These naturally occurring predators serve as eco-friendly alternatives to chemical pesticides and...
Antimicrobial Effectiveness01:28

Antimicrobial Effectiveness

The effectiveness of antimicrobial agents depends on various factors influencing their ability to eliminate microbial populations. Larger microbial populations require more time for complete eradication, emphasizing the importance of population size analysis when evaluating antimicrobial efficacy.Microbial resistance to antimicrobial agents varies significantly. Highly resilient microorganisms include endospores, gram-negative bacteria, and non-enveloped viruses, while prions are exceptionally...
Probiotics01:22

Probiotics

Probiotics are live, non-pathogenic microorganisms that confer health benefits by modulating the gut microbiota. The human gastrointestinal tract harbors a complex microbial ecosystem, and the balance of this microbiota is crucial for digestive and systemic health. Among the most extensively studied and utilized probiotics are species formerly classified within the genera Lactobacillus and Bifidobacterium. These organisms not only naturally colonize the human gut but are also consumed through...

Microbiota Modulation by Antibiotics

Antibiotics have revolutionized modern medicine by saving countless lives from bacterial infections. However, their widespread use has inadvertently harmed the delicate balance of the human gut microbiota. The gut microbiota, a complex community of bacteria, archaea, viruses, and fungi, plays a vital role in regulating metabolism, immune responses, and maintaining intestinal health. Antibiotics, especially broad-spectrum types, disrupt this ecosystem by eradicating both harmful and beneficial...
Clinical Significance of Antibiotic Resistance01:25

Clinical Significance of Antibiotic Resistance

Methicillin-resistant Staphylococcus aureus (MRSA) presents a critical public health threat, arising from its capacity to resist β-lactam antibiotics due to acquisition of the mecA gene within the staphylococcal cassette chromosome mec (SCCmec). This gene encodes penicillin-binding protein 2a (PBP2a), which impairs binding efficacy of methicillin and other β-lactams. MRSA has evolved into distinct clonal lineages impacting humans and animals alike, reinforcing its significance within the One...
