When: 2010-03-24

Collection location: Oak Hill Animal Hospital, Oak Hill, West Virginia, USA [Click for map]

Who: Eddee (eddeeee)

No specimen available

AND NOW FOR SOMETHING COMPLETELY DIFFERENT. This was isolated from a nodule on the dogs head, in the bone. It also was in the lung. The X ray shows a lung field. In an X ray Air is black, but if you look around the heart which is the organ in the center you will see a cottony appearance to it. This was later confirmed through Idex laboratory as a high probability of being Blastomyces. What was told to me was that the state WV was once home to large populations of passenger pigeons which are now extinct and they where a carriers Blasto. They would expel the spores though there feces which would pile up in nesting areas. because they where communal nesters. It is still very much in the soil today.

Recognized by sight: Only one species in North America. In the microscopic picture you can see the big broad based budding yeast. The broad base where the new cells bleb off is disgnostic of Blastomyces, given the other clinical aspects. Thanks for posting! I have never heard the story connected with passenger pigeons. Interesting. Dogs are particularly susceptible because they are down at the ground sniffing and inhaling the spores. See also http://botit.botany.wisc.edu/toms_fungi/apr2007.html

Humans can die from it

It depends on how and where it manifest its self and the degree of infection. usually a person doesn’t even know they have it or had it, until they are examined and a Dr can see scare tissue. It can be fatal in humans though. especially immune compromised individuals. It is more common in dogs, especially hunting dogs because there noses are to the ground all the time. This particular case was a blue tic hound 3 years old. I believe he came from from the Ohio river area. We treat this with a drug called ketoconazole. I have seen this now a few dozen times in two years. This is the first time we worked it up.

I have little scars in my lungs from where the fungus started to grow but was beaten back by my immune system. I can still climb hills all day long though :)

I have nodules in my lungs from that stuff. I grew up along the Ohio river.The doctor told me the same story about pigeons carrying the fungus, he did not name the fungus though. Thanks!
