CattleMycotic abortionAbortion during the late part av the gestation
Humans with weakened immune defenceMucoromycosisThe symptoms depend on where in the body the infection takes place, but hyphae grow into the blood vessels around the area of infection (angioinvasion). Angioinvasion leads to thrombosis and necrosis in the infected area.
