Exp Parasitol 2022; 239:108314. [PMID: 35752343 DOI: 10.1016/j.exppara.2022.108314] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2022] [Revised: 06/15/2022] [Accepted: 06/18/2022] [Indexed: 02/05/2023]
Abstract
Albendazole (ALB) is the most used therapeutic drug for trichinellosis treatment, but it has many drawbacks. Hence, the search for alternative natural compounds is a goal for researchers. The present work aimed to test the in vitro anthelmintic effect of Tomex (Allium sativum) against adult and muscular larva of Trichinella spiralis (T. spiralis). We incubated adult forms and muscular larvae of T. spiralis with Tomex at concentrations 10, 50, and 100 μg/mL to evaluate the changes that happened on the cuticle using a scanning electron microscopy (SEM). Although ALB was very effective, Tomex also affected motility and the tegumental structure of T. spiralis, which was in proportion to its concentration and incubation time, as Tomex started the mortality of muscular larvae and adult stages after 4 h at 50 μg/mL, and after 6 h at10 μg/mL. A 50% mortality rate of muscular larvae was recorded after 6 h at 100 μg/mL. However, a 50% mortality rate was recorded after 12 h at 10 μg/mL for the adult stage. Adult worms and muscular larvae of T. spiralis incubated with 100 μg/mL of Tomex displayed loss of normal annulations and creases of the cuticle, multiple vesicles, widening of longitudinal furrow space, and multiple minor loss blebs. Our results suggested that Tomex can be a therapeutic agent against adults and larvae stages of T. spiralis.

Abstract
Female genital tract infections have a high incidence among different age groups and represent an important impact on public health. Among them, vaginitis refers to inflammation of the vulva and/or vagina due to the presence of pathogens that cause trichomoniasis, bacterial vaginosis, and vulvovaginal candidiasis. Several discomforts are associated with these infections, as well as pregnancy complications and the facilitation of HIV transmission and acquisition. The increasing resistance of microorganisms to drugs used in therapy is remarkable, since women report the recurrence of these infections and associated comorbidities. Different resistant mechanisms already described for the drugs used in the therapy against Trichomonas vaginalis, Candida spp., and Gardnerella vaginalis, as well as aspects related to pathogenesis and treatment, are discussed in this review. This study aims to contribute to drug design, avoiding therapy ineffectiveness due to drug resistance. Effective alternative therapies to treat vaginitis will reduce the recurrence of infections and, consequently, the high costs generated in the health system, improving women's well-being.

Abstract
Trichomonas vaginalis is the causative agent of the most common non-viral sexually transmitted disease worldwide. The infection may be associated with severe complications, including infertility, preterm labour, cancer and an increased risk of human immunodeficiency virus (HIV) transmission. Treatment remains almost exclusively based on 5-nitroimidazoles, but resistance is on the rise. This article provides an overview of clinically evaluated systemic and topical treatment options for human trichomoniasis and summarises the current state of knowledge on various herbal, semisynthetic and synthetic compounds evaluated for their anti-Trichomonas efficacy in vitro.

Abstract
BACKGROUND From the past five decades, metronidazole and tinidazole have been used for treating nonresistant and resistant giardiasis and trichomoniasis. However, due to the occurrence of drug resistance to standard therapy idealizes us to explore some additional therapies which is cost-effective, easy accessibility, and natural which has least side effects. Manuka honey obtained from Leptospermum scoparium is well known for its antibacterial and wound healing properties and is thought to be a better option as an additional therapy. OBJECTIVE The present study was conducted to find out the effect of manuka honey on anaerobic protozoans that includes Giardia and Trichomonas under in vitro conditions in comparison to metronidazole and tinidazole. MATERIALS AND METHODS Axenic culture of Giardia lamblia strain Portland 1 and Trichomonas vaginalis strain 413 was used for drug sensitivity assay to tinidazole, metronidazole, and manuka honey with the highest concentration of 17.1 μg/ml, 24.7 μg/ml, and 50%v/v by using (3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, a tetrazole). For this, head-to-head comparison has been done and IC 50 of the standard drug as well as manuka honey was calculated. RESULTS The result showed that percentage inhibition on the growth of both the parasites is dependent on concentration as well as exposure time of the drug. The calculated IC 50 was found to be 5.6%v/v and 1.5%v/v for manuka honey with respect to G. lamblia and T. vaginalis. CONCLUSION The present study suggests that manuka honey can be used as an additional therapy for the patient with giardiasis or trichomoniasis. However, in vivo study in the near future will elucidate more about the effectiveness of honey in treating parasitic infections.

Abstract
Trichomonosis, caused by the protozoan parasite Trichomonas vaginalis, is a curable sexually transmitted disease that is most commonly encountered worldwide. Increasing importance of trichomoniasis and emerging of resistance against metronidazole lead to search for alternative drugs with different mode of activity. The purpose of this study was to determine in vitro activity of ceragenins (CSA-13, CSA-44, CSA-13, and CSA-138) against the metronidazole-susceptible (ATCC 30001) and metronidazole-resistant (ATCC 50138) strains of T. vaginalis. The effective concentrations were evaluated using two strains of T. vaginalis with different metronidazole susceptibilities (ATCC 30001 and ATCC 50138) in the presence of dilution series of ceragenins in 24-well microtitre assays. Overall, all the ceragenins killed the metronidazole-susceptible (ATCC 30001) and metronidazole-resistant (ATCC 50138) strains of T. vaginalis (p>0.05). With regard to the their effects against the studied strains of T. vaginalis, in order of effectiveness, overall, the ceragenins ordered as CSA-13 (the most effective), CSA-131 and CSA-138 (effective similarly), and CSA-44 (the least effective) (p<0.05). All of the ceragenins reduced the trophozoite numbers of both of studied strains of T. vaginalis with a time- and dose- dependent manner (p<0.05). Although all of the study ceragenins, CSA-13, CSA-44, CSA-13, and CSA-138, killed the studied strains of T. vaginalis. CSA-13 is the leading ceragenin as the most effective anti-trichomonas compound, followed by CSA-131 and CSA-138. They have a potential to have a place in the armemantarium of gynecologic and urologic practice for the management of sexually transmitted diseases.

Abstract
A series of water-soluble silver(i) complexes of the type [Ag(MTZ)2X] [MTZ = 1-(2-hydroxyethyl)-2-methyl-5-nitro-1H-imidazole (metronidazole drug); X = NO3(-), ClO4(-), CF3COO(-), BF4(-) and CH3SO3(-)] was synthesised by the reactions of various Ag(i) salts with metronidazole (MTZ). All the complexes were characterized by ESI-MS spectrometry, solution NMR ((1)H and (13)C) and IR spectroscopy, and elemental analysis. Further evidence for the formation and molecular structure of all the complexes was provided by X-ray single-crystal crystallography. The different counter ions affect the crystal packing of the complexes and thus have an impact on the final geometries. The antimicrobial activities of the complexes against two Gram-positive strains: Staphylococcus aureus ATCC 6538, Staphylococcus epidermidis ATCC 12228, three Gram-negative strains: Pseudomonas aeruginosa ATCC 15442, Escherichia coli ATCC 25922, Proteus hauseri ATCC 13315 and yeast Candida albicans ATCC 10231 were evaluated and compared with antibacterial and antifungal properties of appropriate silver salts, metronidazole and silver sulfadiazine drugs. The newly synthesized compounds exhibited significant antibacterial activity against Gram-positive bacteria, better than the referenced silver sulfadiazine. The best active silver(i)-metronidazole complex contains a methanesulphonate counter-ion. Moreover, the complex inhibited the growth of yeast Candida albicans at a concentration 3-fold lower than that required for silver sulfadiazine. In addition, the complexes containing a tetrafluoroborate and a perchlorate as counter-ions were characterized as effective antibacterial agents against the tested Gram-negative bacteria.

Abstract
Cryptosporidiosis affects humans of all ages, particularly malnourished children and those with compromised immune systems such as HIV/AIDS. This study investigated the therapeutic effects of acetylspiramycin and garlicin on Cryptosporidium infection in institutionalized male drug users receiving rehabilitative treatment. Examination of stool specimens from 903 drug users via modified acid-fast bacilli staining resulted in 172 positive cases. Among them 151 subjects consented to participate in a randomized trial of acetylspiramycin and garlicin in four groups: acetylspiramycin plus garlicin, acetylspiramycin only, garlicin only, and placebo control. The cryptosporidiosis rate was higher in younger subjects with longer drug use history than subjects who are older with shorter history of drug use. After two segments of treatments, 76.2% of the cases achieved negative test results, with the four groups achieving the rates of 92.1%, 76.7%, 72.2%, and 61.8%, respectively (χ(2) = 9.517, P = 0.023). These results indicate clinical potential of garlicin in conjunction with acetylspiramycin in treating cryptosporidiosis.

Abstract
Trichomonas vaginalis is a flagellated parasite that causes trichomonosis, the most common non-viral sexually transmitted disease (STD) in the world. Worryingly, trichomonosis is associated to increased transmission of HIV. Due to high frequency of the infection during pregnancy and the development of metronidazole-resistant isolates, therapeutic alternatives to 5-nitroimidazole are being searched. Triterpenes are natural products presenting several biological activities such as anti-protozoal activity. The aim of this study was to evaluate the in vitro anti-T. vaginalis activity from betulinic and ursolic acids, as well as semisynthetic derivatives obtained. Compounds obtained from betulinic acid presented better activity than those from ursolic acid. Piperazine derivatived from betulinic acid presented minimum inhibitory concentration (MIC) value of 91.2 μM, and the kinetic growth curve performed with parasites treated with this most active compound revealed complete inhibition of trophozoite proliferation at 2 h of incubation and total abolition of trophozoite growth in 24 h, revealing that the piperazine derivative is an efficient trichomonacidal molecule. The same compound promoted total erythrocyte lysis and lactate dehydrogenase (LDH) liberation of 83 and 100% (at 45.6 and 91.2 μM, respectively), indicating parasite membrane damage. The piperazine derivative demonstrated cytotoxic effect against the HMVII and HeLa cell lineages at the MIC value. This is the first report of semisynthetic triterpenoid derivatives with anti-T. vaginalis activity, revealing the high potential of these compounds as trichomonacidal agents.

Abstract
BACKGROUND Bacterial vaginosis (BV) is one of the most common gynecological infections during reproductive age. Although metronidazole is one of the most effective medications recommended as the first-line treatment, it has various side effects. Because of the side effects and contraindications of some chemical medicines, using herbs has been investigated in treating BV. OBJECTIVES The aim of this study was to compare the effect of garlic tablet (Garsin) and oral metronidazole in clinical treatment of the BV in women referred to Resalat Health Center, affiliated with Mazandaran University of Medical Sciences, in 2013. PATIENTS AND METHODS This randomized clinical trial was conducted on 120 married women aged 18 to 44 years who were diagnosed with BV by Amsel's clinical criteria and Gram staining. Enrolled women were randomly allocated to two groups of 60 patients and were treated with either garlic tablet or oral metronidazole for seven days. Amsel's criteria and Gram stain were assessed seven to ten days after beginning the treatment period and side effects were registered. RESULTS Amsel's criteria were significantly decreased after treatment with garlic or metronidazole (70% and 48.3%, respectively; P < 0.001). Therapeutic effects of garlic on BV were similar to that of metronidazole (63.3% and 48.3%, respectively; P = 0.141). There were significant differences between the two treatment groups in terms of side effects; metronidazole was associated with more complications (P = 0.032). CONCLUSIONS This study reveals that garlic could be a suitable alternative for metronidazole in treatment of BV in those interested in herbal medicines or those affected by side effects of metronidazole.

Abstract
Trichomonas gallinae is the causative agent of canker in pigeon. This work was carried out to investigate in the vitro and in vivo efficacy of aqueous water extract of garlic (AGE) on the growth of T. gallinae infecting pigeons compared to those of metronidazole (MTZ). MTZ and AGE were added, at different concentrations, to glucose-serum broth medium containing 1 × 10(4) trophozoites/ml. In the in vivo experiment, 48 squabs were grouped into four groups. The first group (gr. I) was not infected and not treated. Each squab of the other group was infected with 1 × 10(4) trophozoites. The second group (gr. II) was infected and not treated. On day 0, the third group (gr. III) was treated with MTZ (50 mg/kg BW) and the fourth group (gr. IV) was treated with AGE (200 mg/kg BW) for seven successive days in drinking water. In vitro study revealed that the MLC, 24, 48, and 72 h post treatment were 50, 25, and 12.5 μg/ml, respectively, for MTZ and 75, 50, and 50 mg/ml, respectively, for AGE. Garlic (200 mg/kg BW) had the highest antitrichomonal effect and shortened course of treatment of pigeons from 7 days in gr. III to 5 days. Squabs in gr. II suffered from macrocytic hypochromic anemia, whereas squabs in grs. III and IV showed normal blood pictures. Serum total protein, albumin, and globulin were increased, whereas AST, ALT, and the total cholesterol were decreased in grs. III and IV when compared to those of gr. II. Pigeons protected with AGE showed increased body weight and reduced mortality percentage than the other groups. Our results indicated that garlic may be a promising phytotherapeutic agent for protection against trichomoniasis in pigeons.
