“…1 Regions with a few months of relative humidity below 50% have low infestations. 2 In temperate regions, Dermatophagoides pteronyssinus, Dermatophagoides farinae, and Euroglyphus maynei (family: Pyroglyphidae) are the most commonly species found. In tropical and subtropical areas, Blomia tropicalis (family Glycyphagidae) and D. pteronyssinus are the most frequent species, while D. farinae is rarely found.…”

Background: The published data on house dust mite (HDM) sensitization from Egypt are scanty. We sought to investigate the sensitization to five different types of HDM among a group of allergic children in a trial to outline the most frequent sensitizing strains in the Cairo Province. Methods: We consecutively enrolled 100 asthmatic patients, aged 1-7 years, of whom 22 had concomitant skin allergy. Skin prick testing was performed using allergen extracts of Dermatophagoides pteronyssinus, Dermatophagoides farinae, Lepidoglyphus destructor, Tyrophagus putrescentiae, and Acarus siro. Results: Twenty-four patients (24%) were sensitized to one or more strains of HDM. Sensitization to one strain was revealed in 12% of the studied sample, while sensitization to two or three strains was detected in 8% and 4% respectively. Twelve percent of the enrolled children were sensitive to D. pteronyssinus, 11% to D. farinae, 7% to L. destructor, 6% to T. putrescentiae, and 4% to A. siro. Eight out of the 12 (66%) children sensitive to one strain had mild intermittent asthma, while five out of eight (62.5%) sensitive to two strains had moderate persistent asthma. All children sensitized to three strains of HDM had persistent rather than intermittent asthma. HDM sensitization did not correlate significantly to the history of sun exposure, bed mattresses and pillows, living in farms, or exposure to stored grains. The co-existence of atopic dermatitis tended to have a higher rate of HDM sensitization. Conclusion: D. pteronyssinus and D. farinae represent the most common sensitizing strains in the studied sample. Wider-scale population-based studies are needed to assess the prevalence of HDM allergy and its clinical correlates in our country.

“…Sin embargo, la presencia de las demás especies ha sido reportada en varios trabajos por diversos investigadores, lo cual puede estar sujeto a factores climáticos que no son completamente acertados dada su amplia variabilidad por ciudad, localidad o microambiente. En general, una humedad relativa alrededor del 55% es suficiente para la supervivencia de los ácaros del polvo [20].…”

Resumen. Introducción: los ácaros son microrganismos que se encuentran presentes en el polvo común de los hogares y que, en la mayoría de las ocasiones, generan enfermedades de origen respiratorio y dermatológico. Esto afecta significativamente la calidad de vida y hace que esta problemática sea de interés en salud pública veterinaria, debido a la posible relación de los ácaros con la tenencia de animales. El objetivo general de este trabajo fue determinar la cantidad de ácaros intradomiciliarios/gramos de polvo en noventa hogares de tres localidades de Bogotá (Ciudad Bolívar, Rafael Uribe Uribe y San Cristóbal). Métodos: se basó en la recolección de muestras por medio de aspirados de colchones, almohadas y piso. Se trabajaron 30 hogares en las tres localidades mencionadas, para un total de 90 familias y 270 muestras de polvo. Resultados: por familia se condensaron en un formato establecido, en el cual se especificó la cantidad de ácaros por gramo de polvo obtenido. Posteriormente, los datos se analizaron con el uso de estadística descriptiva y medidas de tendencia central. Se encontró que la especie más determinante fue el Dermatophagoides pteronissynus con mayor porcentaje en almohadas (Ciudad Bolívar, 71,32%; Rafael Uribe Uribe, 69,66%, y San Cristóbal, 75%). Sin embargo, en colchones y piso también se evidenció una predominancia porcentual. Conclusiones: los mayores promedios de ácaros/gramo de polvo se encontraron en colchones de las localidades de Ciudad Bolívar (92,50) y San Cristóbal (617,49), mientras que en la de Rafael Uribe Uribe lo obtuvo el piso (36,59).Palabras clave: ácaros intradomiciliarios, calidad de vida, salud pública veterinaria. Finding House Dust Mites in 90 Homes in Three Districts of Bogota, ColombiaAbstract. Introduction: mites are microorganisms found in the common house dust, which in most cases cause respiratory and skin diseases. This has a significant impact on quality of life and turns this issue into a veterinary public health matter, given that house mites are potentially related to having pets. The general objective of this paper is to determine the amount of house mites/grams of dust in ninety homes in three areas of Bogota (Ciudad Bolivar, Rafael Uribe Uribe and San Cristobal). Methods: the methodology was based upon collecting samples by vacuuming mattresses, pillows and floors. Works were conducted in thirty houses in such areas, having a total of ninety families and 270 dust samples. Results: per family they were compiled in the stated form specifying the amount of dust mites per gram of dust. Then, the collected data were analyzed through descriptive statistics and measures of central tendency. The most determinant species was found to be the Dermatophagoides pteronissynus with the highest percentage found in pillows (Ciudad Bolivar, 71.32%; Rafael Uribe Uribe, 69.66%, and San Cristobal, 75%). However, mattresses and floors also showed a predominant percentage. Conclusions: the highest average of dust mites/grams of dust were found in the mattresses of Ciudad Bolivar (9...

“…C. lactis can be found in sugary foods, such as white sugar, brown sugar, fruit sugar, biscuits, Shaqima, pastries, yogurt, candied fruit, prunes, dried plum, red dates, black dates, dried persimmons and the like (14,15). It can also grow and reproduce even if its whole body is soaked into the sugar solution (16). It was reported that, when C. lactis was reared in a tank using Cuban sugar as feeds, it was capable of surviving in a life cycle of some 13 to 18 days in temperature of 25 °C ± 1 °C with relative humidity of 75% (17).…”
