Streptomyces albus is identified in streptomycetes pathogens. It lives in in insects, sponges, and sea sediments. S. albus always can bring actinomycetoma disease. The infection occurs in tissues under the skin. S. somaliensis and S. viridis together appear in complex infections.

The spread of S. albus reports in human with a limited number of incidents in different nations are known. In India, 12 cases surfaced in 1978 with more prevalent in rural areas that affect people exposed to contaminated soil. The disease appears in men frequently than women and common in older individuals.

Streptomyces albus bacteria is present in Actinomycetia class. It has a rod shape structure. It has some special features in its structure.

The bacteria grow as branched threads by releasing round spores at the ends. These spores survive in difficult conditions and grows in optimal criteria.

The colonies are different as they get older. Younger colonies are grey in color with a smooth surface. Older colonies turn white and develop a fuzzy, velvet surface because of the spores.

The colonies stick very tightly to the agar surface and feel tough. The spores are with a clear zone around them.

The microbe S. albus have complex shape formation spores and show antibiotic resistance with exospore production. Some strains show O-alkyl groups on the core oligosaccharide chain.

S. albus is in strain cluster sharing 16S rRNA sequence identity percentage with S. albidoflavus and resistomycificus. Multilocus sequence proposed revising S. pathocidini as a new related species to the S. albidoflavus group. The type strain is DSM 40313 taken from straw named with ATCC 25426 and NBRC 13014.

S. albus is a rare actinomycetes cause actinomycetoma. This disease comes to people in touch with soil or water. It is documented as disease of people living in rural areas with soil erosion or flooding.

The risk is higher with animal bites, insect bites, or medical procedures like injections. The infection starts when spores enter the skin through wounds or openings. These hyphae increase in the tissue and grow as granulomas along other species. The infection spreads to lungs or blood vessels.

S. albus expressing gene clusters and secondary metabolites is used for expressing Streptomyces metabolite gene clusters. Streptomyces albus produces carotenoids and hybrid polyketides, nonribosomal peptides with antimycins and epialteramide, indigoidine & surugamides. It also makes glycosylate compounds like paulomycin and paulomenol.

Some studies provide insight to the human lung strain S. albus TR1341 makes sideromycin A, a substance that alters gene activity linked to inflammation & oxidative stress in human lung cells.

The strain 1597 produces septacidin congeners causes a type of cell death that triggers immunity and can inhibit tumor growth in mice. Our innate immune defenses inflammation activates the adaptive response to eliminate S. albus bacteria.

This adaptive response is triggered when unique S. albus markers are detected. Plasma cells, histocompatibility cell with T cell receptors block the bacteria from attaching to host cells.

Streptomyces albus causes a tissue infection called actinomycetoma. It leads to painful red lumps on the skin membrane. These lumps convert to sores over time showing chronic nature.

People with S. albus have systemic issues with fever and night sweat. The infection impacts overall health, it also spread arthritis, bone, and heart infections.

Streptomyces albus attacks the respiratory system. Coughing up blood are symptoms in respiratory complications from infection.

The gram staining test results as gram-positive. It does not lose its purple color treating with the ethyl alcohol and iodine.

S. albus forms can grow on several media like ISP 4 and Suter without tyrosine. It can develop a grey aerial growth.

Some biochemical tests identify S. albus by its glucose and indole test from tryptophan, it breaks down casein and citrate.

16S rRNA gene sequence of Streptomyces albus are very similar in different strains in NCBI Taxonomy Browser has these sequences. It helps accurately identify. The CINv1 strain has a 100% match with another strain from straw.

  • Preventing infections involves several actions and good hygiene. Wash your hands with sanitizers and alcohol.
  • Avoid drinking contaminated water use filtered or boiled water.
  • Don’t eat uncooked meat and wash fruits and veggies before using. Clean toys and surfaces around children.
