Industry specialists. Offering innovative products.

PathCon Laboratories produces their own high-quality microbiological media and reagents, which are more reliable than mass-produced petri dishes, supplying discerning clients such as the Centers for Disease Control and Prevention (CDC) and other agencies and health departments, that can be internally administered for self-monitoring.

Why PathCon? Accuracy. Expertise. Specialization.

PathCon scientists are the leading experts in Legionnaires’ disease. As the first laboratory to offer Legionella testing services to the private sector, we have investigated outbreaks in the U.S. and many other parts of the world. Our company was started by world authorities in their fields. In fact, two of our scientists have Legionella strains named after them.

PathCon is considered the reference laboratory for the detection, enumeration and identification of bacteria and fungi in building related settings. PathCon routinely analyzes for special pathogens beyond Legionella including:

Anthrax • Cryptosporidium • H5N1, H1N1: Pandemic Influenza • Mycobacterium • Norovirus •
Agents of Fungal Infections such as Aspergillosis and Histoplasmosis



PathCon scientists conducted an investigation of several cases of Legionnaires’ disease reported by passengers on a single cruise ship.
