RATIONALE:

(1) Knowledge of atmospheric pollen is necessary for the diagnosis and management of allergic diseases. This study was carried out to know what the atmospheric pollen concentration in Oaxaca City was; studying the patterns in the airborne pollen fluctuation, the annual total of the daily concentrations, in order to be able to predict pollen as cause for allergic diseases.

METHODS:

(1) Between January 2011 to December 2013: using a Burkard 7-day recording volumetric spore trap in order to monitor the pollen concentration in Oaxaca City. The pollen count was obtained through the slides, counting four longitudinal transverse. The pollen concentrations were correlated with atmospheric variables data.

RESULTS:

(1) In this work 60 pollen types were registered throughout the year, being the higher incidence of pollen months January and February. In the winter, the pollen grains from Fraxinus, Pinus, Alnus and Cupressaceae represented 70% of the total. In the spring, 90% of the total was represented by pollen grains from Poaceae, Pinus, Quercus and Casuarina. The pollen of Poaceae was represented along of the year with aerobiological significance. The meteorological data studied showed correlation with the daily concentrations

CONCLUSIONS:

(1) There was a very well defined season for trees but not for grass and weeds as occurs in northern countries. An assessment of their prevalence therefore requires accurate pollen measurement and is correlated with allergenicity which will be influenced by their number and confirmed by skin test.
