Background: The storage mite, Tyrophagus putrescentiae, detected in the samples collected from stored products and house dust, is one of the major causes of allergic disorders.
Objective: The purpose of this study was to ameliorate the T. putrescentiae faeces allergic immunological disorder by garlic.
Methods: Albino experimental rats were classified into control, inhaled and treated groups. Mass rearing of T. putrescentiae on different diets, and ELISA of some cytokines and IgE techniques were used.
Results: The results obtained showed the highest population of T. putrescentiae reared in four from thirteen tested diets. In addition, significantly higher serum levels of INF-γ and IgE were found in rats treated with faeces than the other groups; especially the garlic-treated group. In contrast, IL-4 was lower in faeces-treated rats than the others; however, the control group had the highest level of IL-4. Statistical analysis of data showed a significant difference between the garlic-treated group and either control or faeces-treated groups (P<0.05).
Conclusions: The population of T. putrescentiae mites peaked in four from thirteen tested diets. The immunological disorder caused by repeated exposure to T. putrescentiae faeces might be modulated by garlic.

The present study was aimed to produce the recombinant protein of allergen component 32 (Tyr p 32) and to identify its immunoreactivity. The cDNA encoding Tyr p 32 was amplified from total RNA of and inserted into pET-28a (+) vector. The constructed plasmid pET-28a (+)-Tyr p 32 was transformed into BL21 (DE3) receptor cells.

Exposure to storage mite (SM) and house dust mite (HDM) allergens is a risk factor for sensitization and asthma development; however, the related immune responses and their pathology have not been fully investigated. The HDMs Dermatophagoides farinae and Dermatophagoides pteronyssinus and SM Tyrophagus putrescentiae are potent allergens that induce asthma. Most SM-related studies have focused on the allergic reactions of individuals by measuring their immunoglobulin (Ig)E expression.

Article Synopsis
- Tyrophagus putrescentiae, a global mould mite, can cause allergies and contaminate food, posing a risk of DNA contamination in laboratory samples through air currents and small spaces.
- The mite's success in various environments is linked to symbiotic bacteria within its body, aiding its adaptation to different food sources, although the impact of gene transfer from bacteria and fungi needs further research.
- Genome sequencing of T. putrescentiae revealed it as a major source of DNA contamination in research, alongside associations with antibiotic-resistant bacteria like E. coli, but no recent horizontal gene transfers were found in this mite or similar species.
