The gram stain is the most frequently used stain in a clinical microbiology laboratory and is usually the first step in identifying bacteria. Based on differences in cell wall components, bacteria are categorized as either gram-positive (stains dark purple) or gram-negative (stains pink).

2024年8月23日 · One-hundred and eighteen antimicrobial resistance genes (ARGs) were associated with mites and 176 with dust. Both contained ARGs encoding resistance for multi drug resistances,...

2023年8月14日 · The Gram staining is one of the most crucial staining techniques in microbiology. It gets its name from the Danish bacteriologist Hans Christian Gram, who first introduced it in 1882, mainly to identify organisms causing pneumonia. [1] .

House dust mites are typically found on the floors, mattresses, rugs or infesting dried stored products where they feed on micro molds that develop on skin scales and foods. House dust mite feces are known to cause or exacerbate bronchial asthma in sensitized individuals.

2023年8月8日 · Dust mite allergy is an IgE mediated Type 1 hypersensitivity reaction to dust mite allergens, commonly found in household dust. The prevalence of atopic diseases like allergic rhinitis and asthma with house dust mite being the allergen has been increasing.

Mites are minuscule arthropods belonging to the Arachnid class. They are spread almost in all human houses in humid, warm and temperate climate. Their dimensions — about one quarter of a millimeter — make them impossible to be perceived by common eyes.

2022年8月10日 · Gram Staining is the common, important, and most used differential staining techniques in microbiology, which was introduced by Danish Bacteriologist Hans Christian Gram in 1884. This test differentiate the bacteria into Gram Positive and Gram Negative Bacteria, which helps in the classification and differentiations of microorganisms.

There is a general agreement that house dust mites in the home feed on shed skin of humans. The average individual sheds 0.5 to 1.0 gram (~0.02 – 0.04 oz) of skin daily. Spieksma et al. (1971) reported that the mites were sensitive to relative humidity and at 60% or lower the mite population stops growing and dies out.

The mites are difficult to see with the naked eye. They are 0.2 mm long, light pink, spindle shaped, and are normally found feeding on the underside of leaf lets. Milky white eggs are found on vegetative terminals. Many nymphs are found on young folded leaflets. Plant - to-plant infestation occurs by the wind dispersal of infective mites ...
