infection and hepatocellular carcinoma: a comorbidity study.

Background: The implication of human () infection in concomitance with other risk factors such as hepatitis C virus (HCV) and hepatitis B virus (HBV) in the development of hepatocellular carcinoma (HCC) is still under controversy. This work aimed. to evaluate the role of infection in association with hepatitis B virus (HBV), hepatitis C virus (HCV) and other risk factors in the development and/or progress of HCC.

Evaluation of microscopy and PCR for detection of .

Introduction: () diagnosis is an intestinal protozoan parasite globally found in rural and urban areas and is attracting a growing interest. Its prevalence in stool varies from 0.2% to more than 19% depending upon the population studied.

Performance of formalin ethyl acetate, percoll sedimentation and ELISA for the detection of infection in asymptomatic children.

This study aimed to assess the performance of formalin ethyl acetate (FEA)/modified Ziehl-Neelsen (MZN), and percoll technique/MZN for the diagnosis of cryptosporidiosis among asymptomatic children compared to ELISA coproantigen. The study was conducted on 100 children in a rural area in Kafr El-Sheikh governorate. Stool samples were collected and examined by the three techniques.

Intestinal Microsporidia Infection in Leukemic Children: Microscopic and Molecular Detection.

Background: Microsporidia infection was originally described as an immunocompromised associated pathogen. Limitations to correct microscopic diagnosis of microsporidia include size of the organism presenting a challenge even to a highly competent laboratory expert.

Objective: The present study aimed to detect microsporidia infection among leukemic children.

Genotype analysis of T. gondii strains associated with human infection in Egypt.

The distribution of Toxoplasma gondii genotypes varies from one geographic area to another. The present study aimed to determine T. gondii genotypes associated with human infection in Egypt.
