Straight from the Horse’s Lung: Rhodococcus Equi

Originally described as a pathogen in 1923, Corynebacterium equi was isolated from the lungs of ten foals (aka a young horse) who had pneumonia (1). Its name was later changed to rhodococcus (aka red coccus), and can be mistaken for mycobacterium spp due to its sometimes acid-fast appearance (2). It is known to infect horses,

Coccidioides (from now on, called Cocci) is an endemic fungi that exists in two forms, yeast and mold, that is endemic to the southeastern United States (1). It is related to both Histoplasma and Blastomyces with two species known to infect humans. C. immitis and C. posadasii. Arthroconidia can be transported in soil or fomites,

What to do with MDR Acinetobacter Baumannii?

Here in the DrGermophile ranks, we talk about all beta-lactamases and how awesome they are. In particular, we like sulbactam. It is in combination with ampicillin, and its use is unappreciated to the uninitiated, but it plays a role in infections such as anaerobic pneumonia. It has a reasonably broad spectrum of activity, losing out

Dogs, dirty mouths, cancer, and booze: What you need to know about Capnocytophaga

There are multiple associations in medicine where the mere mention of a location, occupation, or risk factor elicits a response with regards to the disease. In infectious disease, there are multiple such as “spelunking” being associated with histoplasmosis, IV drug abuser associated with MRSA endocarditis, or cows placentas being associated with Q fever. When it

How Trench Warfare Lead to the Discovery of Bartonella Quintana – Among Other Things

(While I do not anticipate this to alter the post, I should note that one name that has published several articles into B. quintana is Didier Raoult. If that name sounds familiar, he was the guy who published a large case series of patients with COVID-19 who were treated with HCQ and kickstarted the HCQ

Actinomycoses Infections

Unlike some of my previous recent posts (read: Leishmania, Hantavirus), I think this one is of value. The reason being this bug is not thought of (outside of medical school, when it is learned with Nocardia). Most of the time, this infection is diagnosed by the pathologist, after a surgery to remove what is thought

The Unholy Trinity

Fever, thrombocytopenia, and transaminitis. I can be describing full blown septic shock with DIC, HIT (especially if you get a clot in this setting) and TTP (again, clots causing fever and Budd Chiari). Having said that, there is a selection of infections that tend to cause this pattern of fever, low platelets, and elevated LFTs.

Q Fever and Clotting!

A pair of Q fever studies: Million, Matthieu, et al. “Thrombosis and Antiphospholipid Antibody Syndrome During Acute Q Fever: a Cross-sectional Study.” Medicine, vol. 96, no. 29, 2017, pp. e7578. This is a cross-sectional study from the French National Referral Center for Q fever that sought to determine whether thrombosis in acute Q fever patients was associated
