Now for something completely different: Prototheca, pathogenic algae

The funders had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript. Infections are usually subclinical—detectable only through raised somatic cell counts and the presence of Prototheca in milk—but clinical mastitis has both acute and chronic presentations, both of which reduce milk yield [6,11]. [...]affected cows are culled, representing a large economic and animal welfare burden. More widespread use of molecular techniques, including PCR-restriction fragment length polymorphism (RFLP) assays and matrix-assisted laser desorption/ionization time-of-flight (MALDI-ToF) mass spectrometry, will hopefully improve this situation [3,18].
