Fungal Culture Ascitic Fluid

Fungal culture ascitic fluid is performed on a sample of ascitic fluid to check for the fungal growth in the ascitic fluid (a fluid within the abdomen). This test helps to know whether you have a fungal infection in the abdomen or not.

What are the abdominal fungal infections?

Fungal organisms are found anywhere in the environment. They exist as two forms yeasts and molds. The fungal organisms that exhibit a temperature-dependent switch between these two forms are known as dimorphic. These organisms can cause infections in individuals with poor immunity.

Candida species are the most common form of yeasts that cause fungal infections. These fungal organisms cause bloodstream infection with involvement of other organs. Cryptococcus species are another form of yeasts which can cause infections especially in individuals with poor immunity. Aspergillus genus members are a form of molds which can cause diseases and can trigger the allergic reactions in many individuals. Rhizopus, Mucor, Rhizomucor etc are other forms of molds that rarely cause infection.

Histoplasmosis, blastomycosis, sporotrichosis, coccidioidomycosis, paracoccidioidomycosis, and chromoblastomycosis are fungi that are dimorphic in nature. These fungal organisms exist as yeast form in infected individuals (host) and as a mold form in the environment.

Ascitic fluid is a liquid within the abdomen. This fluid is present in small quantities between the layers of the abdominal wall. It is a pale yellow-colored and clear fluid. It is necessary to reduce the friction of organ movement during digestion. The condition of excess accumulation of this fluid in the abdomen may cause ascites. Infections are one of the major cause for this condition. Abdominal infections can occur due to bacterial or fungal infection. This test helps to determine whether the infection is due to fungus or not.

Fungal peritonitis is an infection characterized by swelling of the peritoneum (the membrane lining the abdomen) caused by fungal organisms. They are less common and mainly affects the individuals with poor immunity. Signs and symptoms of fungal peritonitis are fever, abdominal pain, bloating, tenderness, thirst, loss of appetite, nausea, vomiting, diarrhea, low urine output, etc.

Why this test is performed?

This test is performed as part of routine health screening or to determine the presence of abdominal fungal infections. Your doctor may ask to perform this test if you experience any signs and symptoms of fungal arthritis such as fever, chills, cough, chest pain, shortness of breath, headaches, nausea, fast heartbeat, etc. This test is also performed to monitor and evaluate the treatment effectiveness in individuals receiving treatment for abdominal fungal infections. However, your doctor may ask to perform a susceptibility testing on the fungi isolated from this culture test to determine the antifungal treatment.

The test results may be vary depending on gender, age, health conditions, and other factors.

If the culture test is positive it may indicate the growth of fungal organisms such as isolates of yeast, Aspergillus species, Paecilomyces, or any other fungal organisms in the ascitic fluid. It may indicate the presence of abdominal fungal infections. However, a few more additional tests may also be performed depending on the suspected cause and typical results, along with the physical symptoms to diagnose the exact infection.

If the culture test is negative it means no growth of fungal organisms is detected from the ascitic fluid.

Based on the test results, your doctor may advise you appropriate medical treatments or further diagnostic tests.
