What Causes Candida Parapsilosis?

Untitled design (1)

Candida parapsilosis is a yeast fungus that, although often found as a commensal on the human body, can sometimes lead to infections in various parts. The presence of Candida species in different parts of our body and its implications are topics of increasing concern for medical professionals. From our urine to our gut, understanding how and where this fungus thrives can be key to managing its overgrowth.

Understanding Candida Parapsilosis

Gaining a deeper insight into Candida parapsilosis is pivotal for understanding its implications for human health. From its fundamental nature to the unique traits that make it stand apart from other fungi, let’s delve into the intricacies of this yeast.

  1. General Information
  • Nature: Candida parapsilosis is a yeast-like fungus, one among the several Candida species.
  • Habitat: It primarily colonizes human skin, particularly in the hands, making healthcare workers and hospitalized patients more susceptible to disseminating the fungus.
  • Prevalence: While it’s often overshadowed by its more famous cousin, Candida albicans, C. parapsilosis has been recognized as the second or third most common Candida species causing invasive candidal disease.
  1. Gram Stain Characteristics
  • Appearance: On undergoing a candida parapsilosis gram stain, it exhibits a gram-positive reaction.
  • Meaning: Being gram-positive means it has a thicker peptidoglycan layer in its cell wall, enabling it to retain the crystal violet stain during the staining process.
  • Comparison with Other Yeasts:
Yeast/FungusGram ReactionNotable Traits
Candida parapsilosisGram-positiveThrives on human skin, causes nail infections
Candida albicansGram-positiveMost common Candida species, causes oral thrush
AspergillusGram-negativeCommon in soil, can cause respiratory issues
  1. Significance in Medical Field
  • Candida parapsilosis is particularly significant in neonatal intensive care units and among patients with catheter-related infections.
  • It can form robust biofilms on medical devices, leading to nosocomial infections.
  • Timely identification and intervention are vital to ensure the health and safety of vulnerable patients.

Understanding yeast’s basic traits and behavior is the first step to effectively tackle infections and maintain a healthy balance of microorganisms in our bodies.

Where is Candida Parapsilosis Found?

Candida parapsilosis, while being commensal in many individuals, can turn pathogenic under certain conditions. Here’s an in-depth exploration of the regions this yeast affects and the potential implications:


  • Detection: Finding candida parapsilosis in the urine might raise eyebrows. Unlike bacteria which are more common culprits for UTIs, yeast-induced UTIs are less frequent.
  • Implications: This might indicate a urinary tract infection (UTI) with fungal etiology. Such infections can be especially concerning in immunocompromised individuals.
  • Causes: This can result from a compromised immune system, diabetes, prolonged use of antibiotics, or catheter use.


  • Significance: The presence of Candida parapsilosis in stool can suggest its colonization in the gastrointestinal tract.
  • Symptoms: Some individuals may experience symptoms like bloating, diarrhea, or abdominal discomfort.
  • Concerns: Persistent colonization can lead to an imbalanced gut microbiome, making the gut more permeable to other infections.

Vaginal Area

  • Infections Involved: The vaginal area is susceptible to infections, with Candida parapsilosis responsible for conditions like vaginal yeast infections and vulvovaginitis.
  • Symptoms: Affected women can experience itching, burning sensations, unusual discharge, and overall discomfort.
  • Triggers: Factors like hormonal changes, antibiotics, and uncontrolled diabetes can predispose one to such infections.


  • Manifestation: Candida parapsilosis can lead to nail infections, commonly called candida parapsilosis nail infections.
  • Appearance: Infected nails may appear discolored, thickened, and might show signs of crumbling.
  • Risk Factors: Regular exposure to water, nail injuries, and weakened immunity can enhance susceptibility.


  • Colonization: There’s increasing evidence suggesting that Candida parapsilosis can colonize the gut, especially when the natural balance of gut flora is disturbed.
  • Impacts: An imbalanced gut microbiome might lead to digestive issues, allergies, and could potentially impact mental health.
  • Restoration: Probiotics, a balanced diet, and avoiding unnecessary antibiotics can aid in restoring gut health.


  • Condition: When this yeast manages to enter the bloodstream, it leads to a dangerous condition called candida parapsilosis fungemia.
  • Symptoms: Symptoms might include fever, chills, and shock.
  • Causes: This can result from surgical procedures, intravenous drug use, or compromised immunity.
  • Urgency: It’s a severe medical condition necessitating immediate medical attention.

Comparison of Affected Regions:

RegionCommon SymptomsCauses/Risk Factors
UrineBurning, frequent urinationImmune suppression, catheter use
StoolBloating, diarrheaAntibiotics, compromised gut flora
Vaginal AreaItching, dischargeHormonal changes, antibiotics
NailsDiscoloration, thickeningWater exposure, nail injuries
GutDigestive issuesImbalanced gut flora, antibiotic use
BloodstreamFever, chillsSurgery, IV drug use, compromised immunity

Understanding the potential regions of colonization or infection can help in the timely identification and treatment of associated complications.

Treatment and Resistance

  • Standard Treatments: The primary candida parapsilosis treatment usually involves antifungal medications. The type of medication and duration will depend on the infection’s severity and location.
  • Resistance Concern: There is an alarming concern about candida parapsilosis resistance to fluconazole. Fluconazole is a common antifungal drug, and resistance makes treatment more challenging.


Understanding the causes and manifestations of Candida parapsilosis can help in early detection and effective treatment. Regular medical check-ups, being aware of the symptoms, and maintaining good hygiene can keep this yeast at bay.
