Since fungi are eukaryotes, their cellular makeup and metabolic processes are comparable to those of animals. Some fungi have the potential to cause serious infections that are challenging to find and treat. Candidiasis is a fatals fungus thats grows, particularly in compromised human. Particularlly compared to bacterial diseases, the treats options for fungal infections are quite limited [1].

Among the antifungals constantlly in use includ polyenes, azoles, echinocandins, allylamines and miazines. By directly binding to ergosterol and creeating membrane pores, polyenes like amphotericin B impair the ergosterol biosynthesiss pathways and result in the leakage of vital cell contents. The most popular class of antifungal medications is the azole group. Ergosterol formation is prevented by blocking the lanosterol 14 demethylase (Erg11) enzyme and dangerous sterol intermediates form as a result. Azole antifungal activity on fungus ultimately causes cell lysis and death [2].

Ergosterol function is restricted by antifungal agents such as polyene and azoles. The main consequence of sterol production is ergosterol, which has a crucial intrinsic and signaling role. 

One of the main virulence factors in Biofilm yeast is that the biofilm.

Which is the reason for yeast resistance to antifungals. It is an aggregate of cells and filaments C. albicans Extra Cellular Matrix which is coated with extracellular material (Hyphae and Pseudohyphae). Blankenship et al. C. albicans secreted by yeast cells (ECM).

Preparation of Ethanolic Haloxylon Ammodendron

The main product of Ethanolic haloxylon ammodendron (EHA) tree is whole plant. The by-products of Ethanolic haloxylon ammodendron (EHA) tree are branches and leaves. However, all parts of the haloxylon tree contain essential oil and phynols mainly in, stems and leaves and only a small portion is found in the wood part. Besides, from the haloxylon, oil may be distilled from the haloxylon leaves. The oil of haloxylon leaf contains eugenol as the main component (80 - 90%), whereas the main content of the oil of haloxylon. Haloxylon were obtained and collected from Samawa city desert in Muthanna province. The reflux apparatus andother chemicals were of analytical grade.

Sample Preparation

First, wash the plant and chop it into little pieces. Haloxylon was dried in a drying cabinet at 40-42 degres C for 3-4 days. The powder dried plant material was ground.

Preparation of Ethanolic Extract 

A flask was filled with up to 300 g of haloxylon crude (the powder haloxylon). A 96% ethanol solvent was poured to the flask until the plant components were completely immersed by the solvent. The extraction procedure takes three hours. The solution was then filtered using wattman 1 filter paper. The ethanol extract was mixed and evaporated in an oven set at 45 degrees.

Oral Swab Samples Collection

Oral swab samples (30) were taken from patients, who were told to collect them in a sterile container. The samples were then delivered to the laboratory in a sterile container with ice packs. A questioner sheet was used to record all of the patients' information, including age, gender, illness history and antibiotic use.

Table 1: Media Usedin Thiswork Andtheir Remarks

Media

Sabouraud's Dextrose Agar (SDA): After sterilization and chilling to 50 C, chloramphenicol was added to this medium.

Cornmeal Agar (CMA)

This medium was used to test the yeast's capacity to generate chlamydospores. 

Yeast Extract Agar (YEA)

It was made by diluting 23 g of YEApowder in 1000 ml of distilled water and sterilizing it in an autoclave according to the manufacturer's instructions. It is used to cultivate Candidaspp.

Sabouraud' Dextrose Broth

This media was prepared by melting dextrose (20g) and peptone (10g) in 1000 mldistilled water. The final pH was adjusted to 6.8 and then sterilized by autoclave. It isusedfor cultureof Candida spp.

Virulence Factors of Candida Species

Germtube Production: This is done to know the ability of Candida spp. to produce a germ tube in serumUsing a sterile loop, a little part of a pure colony of C. albicans is inoculated into sterile test tubes containing 0.5ml of each human serum. The resultant mixture is incubated aerobically at 37oC for no more than 2 hours. At 30 minute intervals, a drop of the yeast-serum combination is put on a clean microscope slide, covered with a cover slip and viewed microscopically with the x10 and x40 objective lenses. The emergence of tiny filaments extending from the cell surface verified the establishment of germ tubes. For each test serum, the earliest moment of such germ tube formation is recorded.

Production of Chlamydospores (Dalmau Plate Technique)

Chlamydospores formation and germ tube formation are the two most reliable morphologic criteria for the diagnosis of Candida albicans. The characteristic chlamydospores are produced when the isolates are cultured on Corn Meal Tween-80 Agar, which was performed as follows:

• A plate of Corn Meal Tween-80 Agar was inoculated by making a single hard streak down the center of the plate (slightly cutting the agar) and then three or four streaks across the first streak

• The inoculated area was covered with a sterile 22 × 22 mm coverslip

• The plate was incubated at 28°C for three days

• After incubation, the plate was examined without removing the coverslip on the microscope stage, first using the low-power objective (10×), then the high-power objective (40×)

Chlamydospores were found near the edges of the coverslip as large, highly refractile, thick-walled spherical bodies.

Isolation and Identification

Culture: One-half ml of the collected specimens are inoculated onto Sabouraud's dextroseagar. The inoculates are equally dispersed using a sterilized L-shaped glass rod and incubated as duplicate cultures at 25 C and 37 C to demonstrate dimorphism. While the swabs are streaked onto Sabouraud's dextroseagar and incubated. After 4 weeks of incubation, the cultures were judged negative for growth. On Sabouraud's dextroseagar, yeast colonies were identified based on cultural features.

Biofilm Formation

The biofilm was grown according to the pendera 2001 method Microtiter Plate(MTP) Yeast Biofilm Formation is completely identical to the method and his group (2010) with some Pierce modification followed by C.albicans Petri dishes were used to grow the biofilm. Five out of six isolates were all teste and the steps were followed (CRA) by the method of Congo Red Strong Biofilm that formed a strong biofilm

Biofilm Formation in Plastic Petri Dishes

Plastic Petri dishes with a diameter of (6 cm) were used, at a rate of five dishes for eachIso late with a control dish for each isolate. Then add 1 ml of RPMI-2 suspension and put in each plate 9 ml of 1640. medium Pre-prepared fungi.And incubated at 37°C for 24 hours. Para film -, dishes were surrounded by tape water.

The contents of the dishes (except for the control dishes) were disposed of, where the incubation period lasted hours 48 The dishes were washed with physiological solution three times in a light circular motion to get rid of the Non-adherent floating cells. After this stage, the bottom of the dish appears cloudy, indicating the formation of bio film. The dishes containing the biofilm were dyed by adding 10 ml of violet dyecrystal at a concentration of 1% and left for 45 minutes, then the dye was disposed of and the dishes were washed with water Distilled to get rid of the remnants of the dye, the dishes were dried, then 95% ethanol was added to it for one minute. Then the alcohol was disposed of and the dishes were washed with distilled water, left to dry and then checked 40 X to see the biofilm formed under microscope.

These findings imply that ethanol solvents react differently while picking up the components and that a wide range of polarity is used judiciously for optimal extraction. In addition, polar solvents outperformed non-polar solvents in terms of extraction performance. As a result, the choice of solvent is crucial for extract recovery [3] EHA contains all of the necessary, potentially active and medicinally relevant principles, according to both qualitative and quantitative investigation (Figure1-2).

Candida is a tough pathogen to develop therapeutic activity requirements for. The difficulty is exacerbated for plant extracts, where heterogeneity across samples is to be expected based on genotype, growing region, harvesting time, processing methods, dilution and so on. The extracts used in our investigation were crude, which might explain why they have antifungal action against C.tropicalis, C. albicans and C. dubliniensis at concentrations of up to 100 mg/ml. A highly refined formulation would most likely exhibit antifungal action at  lower concentrations. More experimental and clinical studies are needed and if these antifungals are effective, they might be employed as therapeutic medicines Table 2.1 + denotes a zone of inhibition between7 and 10mm; 2+denotes a zone of inhibition between 11 and 14 mm; 3+ denotes a zone of inhibition between 15and 18mm; and 4+denotes a zone of inhibition between 19and 30mm.

For all extracts, the zone of inhibition was greater at 300 mg/ml concentration than at 200, 100mg/ml concentration. The inhibitory impact has risen in proportion to the amount of extract used. Similar observations were made by Perumalsamy et al. [4] (Figure 3).

The antibacterial activity of the ethanol extraction in the current study demonstrated the therapeutic use of the Haloxylon plant. Microbe sensitivity to different amounts of ethanol extract varied. At the highest oxidation state, some of the most fondamental bioactive phytochemicals are composed of a single substituted phenolic ring. phenols, which are antibacterial and antifungal, are found in many common herbs [5-6]. Hydroxylated phenols have been found to be toxic to microorganisms The number and location of hydroxyl groups on the phenol group are thought to be related to their toxicity to microorganisms, with evidence that more hydroxylation leads to higher toxicity [7] (Figure 4). Enzyme inhibition by the oxidized molecule, possibly reactivity with sulfhydryal groups, or more nonspecific contact with proteins are all hypothesized to be responsible for phenolic toxicity to microbes.
