Trichomonas vaginalis is an extracellular flagellated parasitic protozoan. It adapts to live in anaerobic conditions of the women's vagina and causes Trichomoniasis, a non-viral, sexually transmitted disease (STD). This parasite spreads in all regions of the world, and the global prevalence rate of vaginal Trichomoniasis in women is higher than in men. It is considered a neglected disease in Iraq, as there are few studies about this parasite, especially in Maysan province, where researches are near absent. In this study, two hundred and twentysix vaginal swabs were collected from women who visited hospitals, health centers, and medical clinics in some areas of Maysan province (Amara district, Al-Kahla district, Al-Maymouna district, Al-Majar Al-Kabir district) during the period from November 10, 2019 to February 10, 2020. The microscopic examination of vaginal smears showed that the overall infection rate was 75.22% (170/226). AL-Kahla district had the highest rate of infection (96.15%), while the lowest was in the Maimouna district (60.00%). The age group 34-40 years had the highest infection rate (86.95%), while the age group 15 years had the lowest infection rate (37.50%). Married women had a higher infection (80.92%) than unmarried women (40.62%). The infection rate among nonpregnant women was high (81.11%) than with pregnant women (78.57%). This study showed that vaginal pH has a significant role in protecting the women vagina from Trichomoniasis, once the highest rate of infection (96.63%) was recorded in the vagina with a pH 6, while no infection was recorded at pH 4. It can be concluded that Trichomoniasis is widely spread among women of the Maysan communities, and the condition was affected significantly by some demographic factors such as age, occupation, marital status, husband polygamous, vaginal secretions, and itching and pH of the vagina.

Vaccination has been used effectively to protect from infectious diseases and non-infectious diseases such as cancer and allergies. Different forms of particulate arrangements, including nanoparticles, virus-like particles (VLPs), and virosomes, have been built recently depending on the type of pathogen to be targeted. The ability to conjugate the recombinant Plasmodium yoelii, 19-kDa C-terminal fragment of merozoite surface protein 1 (PyMSP119) on the surface of superparamagnetic magnetite nanoparticles (SPIONs) was explored as a new technique of enhancing vaccination against malaria. Different conjugation strategies were performed to correlate the effects of nanoparticle chemistry surfaces to bind later with the malaria protein. (SPIONs) were prepared by chemical coprecipitation method and coated with 3-aminopropyltriethoxysilane (APTS) alone (as a surface coater), or with both APTS and polyethylene glycol (PEG) (as a shield to protect the malaria protein from proteolytic enzymes) by using a modified silanisation method. X-ray powder diffraction (XRD, Philips Model) patterns indicated that the SPIONs were of high purity with an inverse spinal structure. Fourier Transform Infrared Spectroscopy (FTIR) was collected using PerkinElmer Spectrum 100 Series; spectra of uncoated and coated magnetite nanoparticles confirmed that the silane layer had been coated on the surface Fe3O4. The SPIONs were superparamagnetic as investigated by Vibrating Sample Magnetometry (VSM, Princeton Applied Research, model ISS) and relatively stable in aqueous phase at room temperature and could also be quickly recovered from suspension using an external magnet. Introduce the carboxyl groups onto the SPIONs surfaces, resulting in a relatively high protein binding capacity onto the nanoparticle surfaces. The bare particles had a mean size of around 20 nm with a relatively narrow size distribution. 82% of African Green Monkey fibroblast (COS-7) were alive in nanoparticle suspension using the MTT assay method. The quantity of protein explicitly bound to particles was determined using Sodium Dodecyl Sulfate (SDS) - Polyacrylamide Gel Electrophoresis (PAGE). SDS–PAGE. When the conjugation blend was prepared in EDC, there was approximately 100% binding between PyMSP119 and the Fe3O4-COOH particles because no protein band was apparent at the expected molecular weight for PyMSP119 (45 kDa). The current study investigates the theory that the gradual, persistent release of the malaria antigen may stimulate and maintain an elevated level of immune response for an extended period in vivo, which will be the scope of future work.
