COVID-19 anti immunoglobulin G antibodies serum levels among health care workers post COVID -19 vaccination: A single center study.

Coronavirus disease 2019 (COVID-19) pandemic has urged the scientific community internationally to find answers in terms of therapeutics and vaccines to control the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The post vaccination immune response differs between individuals especially health care workers who are the first line of defense to combat this disease. Our aim was to measure levels of anti-IgG antibodies titer post COVID-19 vaccination among health care workers in Suez Canal University Hospital.

Pathological studies of different genotypes of human Cryptosporidium Egyptian isolates in experimentally mice.

The genotyping of cryptosporidium clinical isolates obtained from 36 gastrointestinal symptomatic patients were identified by nested PCR for amplification of 18S rRNA followed by RFLP analysis using Ssp1 and Vsp1, and then pathological changes between different cryptosporidium genotypes were evaluated in experimentally infected mice. Cryptosporidium genotypes (C. parvum, C.

Evaluation of polymerase chain reaction on amniotic fluid for diagnosis of congenital toxoplasmosis.

The present study assessed sensitivity and specificity of PCR targeting P30 gene in diagnosis of congenital toxoplasmosis using amniotic fluid samples. A total of 358 pregnant women in their first trimester of pregnancy, most of them were asymptomatic while the others suffered lymphadenopathy, fever and/or malaise. The serum sample from each woman was screened for Toxoplasma-specific ELISA IgM & IgG.

Pathophysiological variability of different genotypes of human Blastocystis hominis Egyptian isolates in experimentally infected rats.

The genotyping of Blastocystis hominis clinical isolates obtained from 28 gastrointestinal symptomatic patients and 16 asymptomatic individuals were identified by polymerase chain reaction using sequenced-tagged site (STS) primers. Then, pathophysiological variability between different B. hominis genotypes was evaluated in experimentally infected rats.
