−	*''G. candidum''

−	*Rare
−
−	*Two forms: the yeast-like (glaborous) and fluffy
−
−	*Affects a wide range of species
−
−	*Usually diagnosed post-mortem
−
−	*Affects the mucous membranes, udder, [[Bronchi and bronchioles - Anatomy & Physiology\|bronchi]] and [[Lungs - Anatomy & Physiology\|lungs]]
−
−	*Usually mild, causing suppurative granulomas
−
−	*Can be recovered from otitis externa infections in dogs
−
−	*Organisms appear as rectangular or spherical arthrospores on wet mounts
−	**Thick walled, non-budding, gram positive
−
−	*Grow on Sabouraud's Dextrose agar

−	==Cryptococcosis==	+	[[Cryptococcosis]]

−	*Over 19 species
−	**''C. neoformans'' only major pathogen
−
−	*Worldwide
−
−	*Occurs in high concentrations in pigeon droppings (high creatinine concentration)
−	**The pigeon is not infected
−	**''C. neoformis'' colonise the droppings after they have been excreted
−	**Also found in fruit, milk and soil
−
−	*Exogenous, inhaled infection which is generally sporadic (non-contageous)
−	**Can also be absorbed via skin penetration and ingestion
−
−	*May be a primary pathogen or opportunistic
−
−	*Targets the [[Cardiorespiratory System - Anatomy & Physiology\|respiratory system]]
−	**Including the [[Paranasal sinuses - Anatomy & Physiology\|paranasal sinuses]]
−	**Also can be systemic, cutaneous, visceral, skeletal or ocular
−
−	*Causes sporadic mastitis in cattle
−	**Can spread within the herd
−
−	*Affects the [[Nervous and Special Senses - Anatomy & Physiology#Central Nervous System (CNS)\|CNS]] of dogs and cats
−	**[[Paranasal sinuses - Anatomy & Physiology\|paranasal sinuses]] and [[Pharynx - Anatomy & Physiology\|pharynx]] can be infected with dissemination to the [[Nervous and Special Senses - Anatomy & Physiology#Central Nervous System (CNS)\|CNS]] and other tissues
−	***E.g. [[Lungs - Anatomy & Physiology\|Lungs]], [[Urinary System - Anatomy & Physiology#The Kidney\|kidneys]] and [[Joints - Anatomy & Physiology\|joints]]
−	**Also causes subcutaneous granulomas
−	**The tip of the nose is a common site of infection in cats
−	***See [[Respiratory Fungal Infections - Pathology#In Cats\|here]]
−
−	*Causes myxoma-like lesions of the [[Lungs - Anatomy & Physiology\|lung]] and [[Lips - Anatomy & Physiology\|lip]] in horses
−
−	*Causes cryptococcal meningitis in humans
−
−	*Also affects dolphins, foxes, ferrets, monkeys, birds, cheetahs and guinea-pigs
−
−	*Large yeast with capsule seen using India ink stain
−
−	*Stains with PAS (Periodic acis Schiff)
−
−	*Gram positive
−
−	*Grows on blood agar and Sabouraud's Dextrose agar forming white, granular colonies which become slimy, mucoid and turn creamy/brown within a week
−
−	*Species identified by carbohydrate assimilation tests
−
−	*Antigen and antibody should be tested for as [[Immunoglobulins - WikiBlood\|antibody]] formed by the body is soon overwhelmed and neutralised by abundent polysaccharide antigen from the capsule in active, systemic infections
−	**Latex agglutination for [[Adaptive Immune System - WikiBlood#Actions of the Adaptive Immune System\|antigen]], complement fixation, ELISA and IFAT can be used
