Serum Testosterone-Estradiol Ratio in Toxoplasma-Seropositive Infertile Men: A Prospective, Single-Center Study.

Background: The purpose of the current study was to compare the testosteroneestradiol (T:E2) ratio in Toxoplasma gondii seropositive infertile men with seropositive and seronegative normozoospermic controls.

Methods: Totally, 200 men with normal virilization, 100 with idiopathic infertility and 100 normozoospermic men, were included. Participants underwent medical history assessment, physical examination, semen analysis, testing for T.

Effect of sp. infection on hematological parameters and trace element status in children with iron-deficiency anemia.

Iron deficiency anemia (IDA), which causes greater morbidity and mortality in children, has multifactorial causes, including many helminthic and protozoal infections. Herein, the study aimed to find out the frequency and associated risk of sp. infection among children with IDA, together with the estimation of the serum levels of iron, zinc, copper, and vitamin A.

The potential prophylactic and therapeutic efficacy of progesterone and mifepristone on experimental trichinellosis with ultra-structural studies.

Right up to now, there has not been an effective or safe therapy for trichinellosis. Thus, this study aimed to determine the efficacy of prophylactic and therapeutic regimens of progesterone and mifepristone on the intestinal and muscular phases of experimental Trichinella spiralis infection compared to albendazole. Seven distinct groups of mice were divided as follows: negative, positive, and drug control groups, as well as prophylactic and treatment groups using mifepristone and progesterone.

Impact of latent toxoplasmosis on pneumonic and non-pneumonic COVID-19 patients with estimation of relevant oxidative stress biomarkers.

Susceptibility to COVID-19, the most devastating global pandemic, appears to vary widely across different population groups. Exposure to toxoplasmosis has been proposed as a theory to explain the diversity of these populations. The aim of the present study was to investigate the possible association between latent toxoplasmosis and COVID-19 and its probable correlation with markers of oxidative stress, C-reactive protein (CRP) and ferritin.

Green synthesis of zinc oxide/Allium sativum nano-composite and its efficacy against murine cryptosporidiosis.

Cryptosporidiosis is a global health problem threats life of immunocompromised patients. Allium sativum (A. sativum) is one of the therapeutic options for cryptosporidiosis.

Newly fabricated zinc oxide nanoparticles loaded materials for therapeutic nano delivery in experimental cryptosporidiosis.

Cryptosporidiosis is a global health problem that threatens the lives of immunocompromised patients. This study targets to fabricate and investigate the efficiency of zinc oxide nanoparticles (ZnO-NPs), nitazoxanide (NTZ)-loaded ZnO-NPs, and Allium sativum (A. sativum)-loaded ZnO-NPs in treating cryptosporidiosis.

Toxocariasis: potential association with bronchial asthma, and pneumonia among pediatric children.

Toxocariasis is an underestimated geohelminthic infection which shows respiratory changes concurrent with larval migration. The purpose of the present study was to detect seropositivity in asthmatic and pneumonic children, and in turn to evaluate its association with the children clinical manifestations, laboratory test results, and sociodemographic risk factors. A total of 50 asthmatic, 50 pneumonic children and 50 healthy controls were subjected to stool analysis by direct wet mount and concentration techniques to exclude possible cross reactivity.

An Association Between Blastocystis Subtypes and Colorectal Cancer Patients: A Significant Different Profile from Non-cancer Individuals.

Purpose: Blastocystis is a common enteric human parasite of non-conclusive pathogenicity which may be determined by subtype (ST) variation. Colorectal cancer (CRC) is considered one of the primary causes of cancer mortality. Blastocystis ST7 has been shown to reduce beneficial intestinal microbiota and may exacerbate CRC.

Ginger (Zingiber Officinale)-derived nanoparticles in Schistosoma mansoni infected mice: Hepatoprotective and enhancer of etiological treatment.

Background: Nanotechnology has been manufactured from medicinal plants to develop safe, and effective antischistosmal alternatives to replace today's therapies. The aim of the study is to evaluate the prophylactic effect of ginger-derived nanoparticles (GNPs), and the therapeutic effect of ginger aqueous extract, and GNPs on Schistosoma mansoni (S. mansoni) infected mice compared to praziquantel (PZQ), and mefloquine (MFQ).

in cancer patients receiving chemotherapy: seroprevalence and interferon gamma level.

is an opportunistic parasite causing life-threatening diseases in immune-compromised patients. The purpose of the study is to determine the seroprevalence of in chemotherapy receiving cancer patients in relation to different types of malignancies, and to estimate the level of interferon gamma in seropositive and seronegative cancer patients and healthy controls. Anti- IgG and IgM antibodies, and interferon gamma were analyzed in 120 cancer patients receiving chemotherapy (60 having hematological malignancies and 60 with solid organ tumors) and 60 healthy controls using ELISA method.

Molecular characterization and phylogenetic analysis of Acanthamoeba isolates in tap water of Beni-Suef, Egypt.

The genus Acanthamoeba is a free-living amoeba widely distributed in various aquatic environments. It is an etiologic cause of amoebic encephalitis and keratitis particularly for immunocompromised individuals. The purpose of the present study was to investigate Acanthamoeba species prevalence in household and hospital potable water in Beni-Suef governorate, Egypt, and to employ sequencing methods to identify positive Acanthamoeba species isolates and their potential health risks.

Strongyloides stercoralis larvae found for the first time in tap water using a novel culture method.

Strongyloides stercoralis (S. stercoralis) is a soil-borne helminth but its prevalence in water samples is underestimated. The aim of the present study is to propose non-nutrient agar (NNA) as a novel culture method in the diagnosis of Strongyloides and to detect the prevalence rate of S.

Case Report of Human Urinary Myiasis Caused by (Diptera: Psychodidae) with Morphological Description of Larva and Pupa.

Background: Urinary myiasis is a form of myiasis caused mainly by larvae of , , , , , , and rarely by and

Methods: This report presents a case of female patient complaining of dysuria and frequency of micturition associated with intermittent passage of small, motile, dark-colored worm-like organisms in urine. She was a married housewife aged 24 years old referred from the Tropical Outpatient Clinic of Beni-Suef University Hospital, Egypt. The patient was subjected to a full questionnaire sheet and investigations such as CBC, stool and urine analysis and urinary ultrasonography.

Blastocystis subtypes isolated from irritable bowel syndrome patients and co-infection with Helicobacter pylori.

Irritable bowel syndrome (IBS) is a chronic functional gastrointestinal disease presenting clinically by abdominal pain with alteration of bowel habits. Although IBS has uncertain etiology, chronic gut inflammation due to persistent exposure to an infectious agent including Blastocystis sp. was proposed.
