Abstract The polymorphic fungus Candida albicans is a member of the normal human microbiome. In most individuals, C.

Virulence factors of candida albicans

For its pathogenicity, its ovoid-shaped budding yeast and parallel-walled true hyphae forms are the most important. The hyphae form is more prevalent for an infection, while the yeast form is believed to be important in the spread of C. The role of pseudohyphae is not very well understood, other than being an intermediate form between yeast and hyphae [1].

Several factors can cause a change in morphology, such as pH differences, temperature changes, carbon dioxide levels, starvation, and quorum-sensing molecules farnesol, tyrosol, and dodecanol [11].

Adhesins Candida albicans have special sets of glycosylphosphatidylinositol GPI -linked cell surface glycoproteins that allow it to adhere to the surfaces of microorganisms. These glycoproteins are encoded by 8 sets of agglutinin-like sequence ALS genes, ranging from Als and Als9.

For adhesion, the Als3 gene appears to the most important as it is upregulated during an infection of oral and vaginal epithelial cells. Also, it helps with biofilm formation by helping with adhesion to each other [12].

Invasins Along with adhesion, Als3 proteins can function as invasins that help with the invasion of C. Another important invasin gene is Ssa1, which normally codes for heat-shock proteins.

Another method of invasion is the active penetration of C. Biofilm formation Candida albicans have the ability to form biofilms on living and non-living surfaces, such as mucosal membranes and catheters, respectively.

After the adherence of yeast cells to the surface, there is development of hyphae cells in the upper part of the biofilm. In the process of biofilm formation, Bcr1, Tec1 and Efg1 function as important transcriptional factors [14].

Recent studies show that biofilms protect C. Secreted hydrolases Candida albicans secrete 3 main classes of hydrolases: There are about 10 known secreted aspartic proteases Sapand their exact contribution to pathogenicity is controversial.

For phospholipases, there are 4 major classes A, B, C, and Dand all 5 members of the B class are involved with the disruption of a host cell surface. Thirdly, lipases are consisted of 10 members LIPand studies show that there is decreased virulence in their absent [16].

Metabolic adaption Candida albicans are usually found in the gastrointestinal microbiome of healthy individuals, and in this environment, nutrient levels are relatively high. However, during niche changes in the course of an infection, available nutrient levels will also change. Consequently, the fungus can quickly undergo metabolic adaption, such as their glycolysis, gluconeogenesis, and starvation responses [17].

For example, in the case of candidemia, C. Due to this flexibility, C. Clinical features There are 3 major type of infections caused by Candida albicans: Symptoms Oropharyngeal candidiasis Oropharyngeal Candidiasis: WebMD [4] Oropharyngeal candidiasis is an infection in the mouth and throat area.

Thrush can be removed with a blade or a cotton-tipped swab, but the underlying tissue will be irritable and show a distinct redness. This infected area will cause soreness and difficultly during eating [18].

Vulvovaginal genital candidiasis Vulvovaginal candidiasis is the infection of the genital region, typically the vaginal walls, in women.

The vaginal yeast infection causes itchiness and a burning-sensation in the vagina and surrounding tissues. Also, a white discharge — described with an appearance similar to white cottage cheese — is typically present. Genital candidiasis is much more prevalent in women, but men can also contract it.

Although it is not considered an STD, men are usually infected after sex with a woman having a vaginal yeast infection.

Symptoms involved rash, irritation on the head and surrounding skin of the penis [18]. Invasive candidiasis candidemia Invasive candidiasis or candidemia is the infection of C. This leads to its invasion of organs throughout the body, such as the kidney, liver, brain, and many more.

Patients began to suffer from fevers, chills, fatigue, muscles aches, and abdominal pains. Compromised immune systems can be caused by chemotherapy, transplantation, broad-spectrum antibiotics, and much more [19].

Mortality Most patients can recover from oral and genital candidiasis after a treatment with antifungal such as fluconazole. On the other hand, candidemia is much more life-threatening infection.The Impact of Lemongrass, Oregano, and Thyme Essential Oils on Candida albicans’ Virulence Factors.

Candidiasis is a common infection of the skin, oral cavity and esophagus, gastrointestinal tract, vagina and vascular system of humans.

Although most infections occur in patients who are immunocompromised or debilitated in some other way, the organism most often responsible for disease, Candida.

Candida albicans is a polymorphic fungus that can grow in several different forms, primarily yeast, pseudohyphae, and hyphae. For its pathogenicity, its ovoid-shaped budding yeast and parallel-walled true hyphae forms are the most important.

The Kex2p protein of Candida albicans, an opportunistic fungal pathogen, participates in pathways that lead to the expression of two of the organism's best characterized virulence factors: hyphal formation and the secretion of proteinases.
