The Award Winning Biomaster Antimicrobial Range

The Biomaster range of Antimicrobial & antibacterial Silverbased additives has been successfully tested on over 50 different organisms in over 2,000 applications. The test list below highlights the main strains tested and their properties.

---

Aspergillus amstelodami:

Anamorphic state of Eurotium amstelodami: Yellow mould fungus found in soil and house-dust. May be pathogenic. Has been found in cases of pulmonary infection.

---

Aspergillus nidulans:

Yellow mould fungus. Pathogenic, causing chronic granulomatous disease.

---

Aspergillus niger:

Black mould fungus. Irritant spores with mycotoxins. Pathogen, Causing respiratory diseases and cutaneous and subcutaneous infections. Commonly found in bathrooms.

---

Candida albicans:

Saprophytic yeast found in the nasopharynx and faeces. Causes thrush and skin infections.

---

Clostridium difficile:

Gram positive anaerobic spore-forming bacteria. Pathogenic, causing colitis in the human gut. (Please see separate Addmaster information sheet)

---

Corynebacterium minutissimum:

Gram-positive non spore-forming bacillus. Pathogenic, associated with acne.

---

Corynebacterium spp:

Gram-positive, non spore-forming bacilli. Pathogenic, causing a variety of cutaneous and mucocutaneous human diseases such as diphtheria, mastitis, vaginitis etc.

---

Enterobacter gergoviae:

Gram-negative bacillus. Pathogenic, associated with hospital-acquired urinary tract infections.

---

Escherichia coli 0157 H7:

Facultative anaerobic gram-negative bacillus serotype, found in animal intestines and faeces. Strain 0157 H7 is particularly pathogenic, causing gastroenteritis, sometimes fatal.

---

Klebsiella pneumoniae:

Aerobic Gram-negative bacillus, part of the normal intestinal flora of animals and humans. Pathogenic, causing hospital and community acquired infections.

---

Listeria monocytogenes:

Gram-positive aerobic non spore-forming bacillus, found in the intestinal tract of humans. Pathogenic if it enters the bloodstream, causing Listeriosis.

---

Mesophilic aerobes:

Most bacteria are mesophiles, i.e. capable if living and replicating at a wide range of temperatures. Those found in or on the human body have a temperature optimum of 370 to 440C, but many others in found in nature have an optimum of 300C.

---

(MRSA) Methicillin Resistant Staphylococcus aureus:

At the moment there are 27 known pathogenic serotypes of MRSA, each particularly contagious, and resistant to most antibiotic treatments. Common in hospital acquired infections.

---

Mucor racemosus:

Spoilage mould fungus found in soil and house dust. Allergenic spores, causing hypersensitivity.

---

Myceliophthora thermophila:

Fungus, tolerant to exposure to high temperatures, commonly found in garden compost heaps. Used for production of thermostable enzymes for industrial processes. Has been implicated in rare fungal infections in humans.

---

Penicillium chrysogenum:

Commonly occurring blue mould fungus, used industrially for antibiotic production.

---

Proteus mirabilis:

Aerobic Gram-negative bacillus, part of the normal human intestinal flora. Pathogenic, causing urinary tract and intestinal infections.

---

Proteus vulgaris:

Aerobic Gram-negative bacillus, part of the normal human intestinal flora. Pathogenic, causing urinary tract and intestinal infections.

---

Pseudomonas aeruginosa:

Aerobic Gram-negative bacillus, colonies forming a characteristic blue-green pigment with a urine-like odour. Ubiquitous in nature. Pathogenic, being a major cause of hospital-acquired infections.

---

Pseudomonas cepacia:

Aerobic Gram-negative bacillus. Pathogenic, associated with many hospital-acquired infections, and closely associated with cases of cystic fibrosis.

---

Pseudomonas putida:

Aerobic Gram-negative bacillus. Some strains occasionally isolated as opportunistic pathogens.

---

Saccharomyces cerevisiae:

Yeast, capable of aerobic and anaerobic fermentation. Used in the food industry for brewing and baking.

---

Salmonella enteritidis:

Gram-negative bacillus, with over 1000 known pathogenic serotypes, causing enteric or typhoid fever in humans. Found in the gut of animals, birds, and human carriers. Infection is passed through poor.

---

Staphylococcus aureus:

Aerobic Gram-positive coccus. Part of the normal flora of the skin, intestinal and genital tracts and mucous membranes of warm blooded animals. An opportunistic pathogen causing a wide variety of infections.

---

Trychophyton mentagrophytes:

Saprophytic fungus causing dermatophytosis, athletes foot and other chronic skin infections.
