I have noticed that some doctors and physician assistants do not know that white sputum (not clear, but pure white thick sticky sputum) indicates a fungal infection in the lungs and/or the bronchus and/or the trachea. Specially in individuals who are coughing several times per hour, are feeling chest pain, fatigue, and have being diagnosed with lung problems such as bronchiecstasis and/or pulmonary fibrosis.

And I have also noticed that some laboratories are incapable or unwilling to detect these type of pulmonary fungal infections. Either they are using the wrong type of agar plates, or they are not waiting the necessary 3 days (minimum for a good culture result). When doing a sputum culture, they are probably using blood agar plates. That is OK if they are looking for bacteria, but if they are looking for molds (fungus) they should use potato dextrose or malt extract plates, then they have to keep them at the proper temperature range, in the dark, for a minimum of 3 days, in order to create fungal colonies.

The data in this portal will eventually be moved to the "Heath Matters" or the "Microscopy" portal. However I feel that it is sufficiently important to have its own portal for now.

Here are 3 photos of 3 different sputum cultures done in May and June of 2026.

        


I am displaying here micrographs (digital photographs taken through a microscope) of 3 types of molds (fungus) from my sputum cultures. They each created colonies of different colors, one white, one green, and one beige.

Clicking (selecting) any of the small linked-images bellow will display a larger equivalent image.

And when I show these images to some physician assistants or doctors, they don't believe that I am capable of detecting mold in my sputum. Or they ask silly and ridiculous questions such as "Are you certified?".

Do we really need a certification to spit some sputum on an agar plate and wait 3 days for colonies to form?

Microscopist do not need any certification. We are, usually, very intelligent individuals who are very curious about the microscopic world and enjoy using our microscopes to take micrographs of our blood, pathogens, molds, and other microscopic things, so that those who do not have microscopes can also satisfy their curiosity (if they have any about the microscopic world).
