Pythium insidiosum is an oomycete pathogenic in mammals. The infection occurs mainly in tropical and subtropical areas, particularly in horses, dogs and humans. Infection is acquired through small wounds via contact with water that contains motile zoospores or other propagules (zoospores or hyphae).
How do humans get pythiosis?
Human pythiosis is an infectious condition with high morbidity and mortality. The causative agent is the oomycete microorganism Pythium insidiosum. The pathogen inhabits ubiquitously in a wet environment, and direct exposure to the pathogen initiates the infection.
How do dogs get pythiosis?
Pythiosis is an infectious disease caused by a fungus-like organism, Pythiuminsidiosum, that naturally inhabits wetlands, ponds, and swamps. In dogs, the disease usually is manifested by gastroenteritis or dermatitis. Presumably dogs become infected by ingesting, or swimming in contaminated water.
Can humans get pythiosis from dogs?
Animals, including dogs and horses, can contract pythiosis from swimming spores. About 10 cases of humans getting sick from this disease have also been reported in the U.S.
How common is pythiosis?
Pythiosis is a relatively rare, but emerging infectious disease of domestic animals that is derived from an algae-like fungi that enters the body through the nose/sinuses, esophagus, or broken skin through contact with water.

Pythium spp. predominantly affects golf and bowling greens in all turf grass species. Bayer recommends using a preventative treatment such as Signature Stressgard or curative treatment such as Banol.
How is Pythium diagnosed?
Serology Several serologic tests have been developed to diagnose pythiosis in humans and animals. They are: Complement fixation, immunodiffusion, Enzyme-Linked Immunosorbent Assay, immunoperoxidase assay, fluorescent antibodies, and western blot.
What is mucormycosis and what area of the body is most commonly infected?
Mucormycosis mainly affects people who have health problems or take medicines that lower the body's ability to fight germs and sickness. It most commonly affects the sinuses or the lungs after inhaling fungal spores from the air. It can also occur on the skin after a cut, burn, or other type of skin injury.
Is pythiosis contagious?
Depending on the site of entry, infection can lead to different forms of pythiosis i.e. a cutaneous, vascular, ocular, gastrointestinal and a systemic form, which is rarely seen. The infection is not contagious; no animal-animal or animal-human transmission has been reported so far.
Where is pythiosis found?
Pythiosis is the result of being infected by a water mold-like organism called Pythium insidiosum that is most commonly found in water, although it can also be present in soil. This organism can affect the gastrointestinal tract or the skin.
Can humans get Pythium?
Pythium insidiosum is a pathogen that causes disease in both animals and humans. Human infection is rare; however, when it does occur, most patients, especially those having underlying hemoglobinopathy syndromes, such as thalassemia, exhibit a severe form.
How can pythiosis be prevented?
Prevention. In 2004, a new immunotherapeutic vaccine for dogs was made available for pythiosis. As soon as your dog is diagnosed, it should be vaccinated with the pythiosis vaccine to reduce the size of the lesion. Surgery will then be easier and more successful.
How long can a dog live with pythiosis?
Esophageal lesions were present in 2 of 10 dogs. Common laboratory findings included eosinophilia (7/9), hypoalbuminemia (9/9), and hyperglobulinemia (8/9). Median survival time was 26.5 days (range, 0-122 days), and the disease was ultimately fatal in all 10 dogs.
What is human pythiosis?
Pythiosis is an emerging infectious disease caused by the aquatic oomycete Pythium insidiosum, a fungal-like organism. It is believed that P. insidiosum's zoospores, its infected form, play major role in pathogenesis. Vascular and ocular infections are the most common clinical manifestation in humans.
Can cats get Pythium?
Pythiosis is frequently reported in dogs and horses inhabiting tropical, subtropical and temperate areas of the USA, but the disease is rare in domestic cats. The clinical presentation of feline pythiosis includes subcutaneous masses without ulcerated tissue and involvement of the intestinal tract.
What type of infection is histoplasmosis?
Histoplasmosis is an infection caused by a fungus called Histoplasma. The fungus lives in the environment, particularly in soil that contains large amounts of bird or bat droppings.
Where does Pythium come from?
Pythium may come from several sources at different times during crop production. Insects common to greenhouses, fungus gnats (Bradysia impatiens) and shoreflies (Scatella stagnalis), excreted viable P. aphanidermatum oospores after ingestion (9). Fungus gnat larvae and shorefly adults may be vectors.
Is Pythium blight harmful to dogs?
Pythium insidiosum can cause infections in dogs and horses that are life-threatening. It can also cause infection in cattle, cats, equines, captive polar bears and even humans. It is most commonly found in tropical regions or subtropical regions.
Is Pythium a zoonotic?
It is not considered a classic zoonosis, although it is classified as a saprozoonosis by some authors.
Who is prone to mucormycosis?
Mucormycosis is not a contagious disease, it cannot be spread from one person to another. Mucormycosis mainly affects people who are immunocompromised, or patients already infected with other diseases.
Is mucormycosis airborne?
Mucormycosis refers to the disease caused by a growing number of members of the Mucorales. Typically an airborne infection, primary disease is initiated in the upper or lower airways and is associated with the clinical development of sinusitis, rhinocerebral mucormycosis, or pulmonary infection.
How do I know if I have mucormycosis?
Cutaneous (skin) mucormycosis can look like blisters or ulcers, and the infected area may turn black.
...
Symptoms of rhinocerebral (sinus and brain) mucormycosis include:
- One-sided facial swelling.
- Headache.
- Nasal or sinus congestion.
- Black lesions on nasal bridge or upper inside of mouth that quickly become more severe.
- Fever.
How do you identify Pythium root rot?
Symptoms of Pythium root rot may spread in drainage patterns during periods of heavy rainfall. On individual plants, the crowns, roots, rhizomes, and/or stolons will appear dark and greasy. The depth and density of roots will be drastically reduced in affected areas.
What is Pythium which disease does it cause?
Pythium ultimum and Pythium irregulare can infect alfalfa seeds, causing seed blight or rot (pre-emergence damping off), or they can cause water soaking and eventual death of the roots and stems of seedlings as they emerge (post-emergence damping off).
Is Pythium in the soil?
Pythium is a soil-borne organism favored by excessive soil moisture. Spores are spread by contaminated soil, water, tools, and other implements. Pythium is a water mold, so it is particularly severe in poorly drained media.
