Abstract To limit immune responses to gut-resident microbes, mucus and the epithelial barrier physically separate host system from microbial communities. Immunoglobulin A (IgA) antibodies are known help regulate colonization functions of mucus-associated commensals. However, mechanisms whereby other isotypes, including IgG, interface with components promote tolerance MA microbes still being unr...

background: infertility is one of the common problems seen in couples of reproductive age. presence of antisperm antibodies in semen and serum are amongst the causes of immunoinfertility. this study was performed to determine antisperm antibodies in cervicovaginal secretions and serum of infertile women and also measure serum levels of immunoglobulins (igg, igm and iga). methods: the study cons...

Introduction: Rubella infection in early pregnancy can lead to miscarriages, fetal death, or birth of an infant with congenital rubella syndrome (CRS). Like other developing countries, Yemen surveillance is not well-established. So, the aim this study was conducted objectives estimating seroprevalence and potential risk factors acquiring by pregnant women Hodeidah city Yemen. Methods: A cross‐s...

Adenoviruses are widely spread viruses causing infections related mainly to children. Contact with the pathogen may result in the presence of either immunoglobulin (Ig) A or IgG antibodies in the serum. The aim of this study was to assess the prevalence of IgA and IgG antibodies against adenoviruses in serum of children aged 11-27 months, hospitalised at the Public Children's Clinical Hospital ...

By using a semi-quantitative immunoblotting technique, we have analyzed serum immunoglobulin G (IgG) reactivities of patients with limited cutaneous systemic sclerosis and anticentromere antibodies, patients with diffuse systemic sclerosis and antitopoisomerase 1 antibodies, patients with diffuse systemic sclerosis without antitopoisomerase 1 or anticentromere antibodies and age- and gender-mat...

OBJECTIVE To assess the prevalence of cervical antibodies to Chlamydia trachomatis in two different populations and to correlate the findings to culture, direct fluorescent antibody test (DFA) and serum antibodies. SETTING Antenatal clinics and clinic for teenage counselling in Gävle. PATIENTS 1078 pregnant women attending for routine follow up in the third trimester of pregnancy and 256 te...

BACKGROUND It has previously been shown that IgG antibodies from patients with limited cutaneous systemic sclerosis (SSc) bind to specific microvascular endothelial cell antigens. Since patients with limited cutaneous SSc are prone to develop pulmonary arterial hypertension (PAH), and since endothelial cell activation is involved in the pathogenesis of idiopathic PAH (IPAH), a study was underta...

OBJECTIVE To estimate the prevalence of IgG antibodies against B19 virus (B19V) in Makkah and Jeddah, Saudi Arabia. METHODS B19V-specific IgG antibodies were detected by a commercial indirect enzyme-linked immunosorbent assay in sera of 400 paediatric patients (185 males and 215 females) aged 1-17 years. RESULTS Of the 400 patients, 80 (20%) had sera positive for B19V-specific IgG. The diff...
