ABSTRACT
Lung granulomas are uncommon in Thailand. The disease typically develops from an occupational environment and is mostly caused by infection. Herein is a case report of a female patient, aged 48, working as a nurse in an Accident and Emergency Department at a hospital. Eighteen years prior to admission the patient was diagnosed with myasthenia gravis and pulmonary tuberculosis. The chest X-ray and CT scans showed a solitary pulmonary nodule in the lower left lung. The patient received an open thoracotomy with a left lobectomy. Granulomatous and nonseptate hyphae were found in the pathology diagnosis. The patient was thus diagnosed as having a lung granuloma. The galactomannan antigen test was positive. The solitary pulmonary nodule—found from the use of a Polymerase Chain Reaction (PCR) test—was an Aspergillus spp. The fungus culture was collected from air samples. The air samples were collected by the impaction technique using a microbial air sampler. Three types of Aspergillus spp. were found as well as Penicillium spp. and Monilia sitophila. The Aspergillus spp. was a match for the patient's disease. The patient was diagnosed as having a lung granuloma possibly Aspergillus nodule which was caused by airborne Aspergillus spp. from the occupational environment.

ABSTRACT
Background : Because common fungal media used in laboratory learning are expensive, and the nature of fungi in easily growing and the plenty of agricultural products in our country, can make it be possible to perform the experiment to prove the hypothesis and develop the cheaper media.Objective : To develop the new fungal media for laboratory learning.Methods : Cultivate molds in the media each prepared from sweet potato, pumpkin, soy bean, mung bean and red bean, then select the one that yields the best fungal growth to develop the media formular for assessment of fungal growth comparing to the standard media.Results : Four formulae of the new fungal media containing pumpkin sucrose agar (PKSA), pumpkin dextrose agar (PKDA), red bean-pumpkin sucrose agar (RPSA), red bean-pumpkin dextrose agar (RPDA), were developed and tested to cultivate 7 molds compared with those of potato dextrose agar (PDA). Four species showed better growth in the 4 formulae and 2 species showed better growth in PDA, while 1 species showed no difference among all media (p
ABSTRACT
Background : Because the analytical-grade agar commonly used in microbiological laboratory is very expensive. The food-grade agar, the lower cost one, was introduced for preparation of commonly used media in attempt to reduce the cost of this purpose.Objective : To assess the potentiality of the food grade agar in preparation of bacterial and fungal media for microbiological laboratory learning.Methods : Eighty six strains of bacteria were cultivated on Nutrient agar (NA) and Sugar assimilation media, and twenty two fungal strains (19 molds, 3 yeasts) were cultivated on Sabouraud dextrose agar (SDA). These media were prepared by the food grade agar. The quality and quantity of these microorganism growth were compared to those of cultivation on media prepared by the analytical grade agar.Results : All bacterial strains showed the similar characteristics and also biochemical and physiological properties whether cultivation on media prepared from food grade agar or analytical grade agar. Nine strains of molds showed no significant difference on both SDAs, while each of 5 strains on food grade agar-SDA were included in the less and better growth groups (Paired t-test, p
