This work was designed to characterize the HIV viral antibodies in HIV infected and non-HIV infected HBsAg seropositive patients. Fifty non HIV infected (male = 25; female = 25)and 50 HIV infected HBsAg seropositive patients (male – n = 25; female – n = 25) aged 6 – 64 years recruited from the medical outpatient department of Baptist Medical Centre, Saki – Oyo State – Nigeria were investigated ...

Although considered a "joint disease," rheumatoid arthritis is associated with the involvement of extra-articular manifestations. The aim of the study is the investigation and comparison of frequency and type of extra-articular manifestations in a well defined community based cohort of patients with seropositive and seronegative rheumatoid arthritis. Using the ACR (1987) criteria for rheumatoid...

CagA seropositivity is an important risk factor for gastric adenocarcinoma and duodenal ulcer. However, CagA seropositivity is also found in Helicobacter pylori-seronegative subjects. Is CagA seropositivity in these subjects a sign of a past H. pylori infection, or does it represent a false-positive reaction? This study investigates the intensity of the CagA immune reaction and the variation in...

Abstract Brucella canis had not been isolated in the Netherlands until November 2016, when it was from a dog imported Romania. Including this case, 16 suspected cases were notified to authorities during following 25 months. Of these dogs, 10 seropositive; tracking investigations found another 8 seropositive littermates. All animals rescue dogs Eastern Europe. B. cultured urine, blood, and other...

Human herpesvirus 8 (HHV-8) infection is common in Africa. We examined the distribution of HHV-8 within families in rural Tanzania to determine routes of spread. HHV-8 infection was assessed by measuring antibody reactivity with a K8.1 (lytic-phase antigen) immunoassay. The prevalence increased from 3.7% (1/27) among infants to 58.1% (36/62) among children aged 3-4 years and 89.0% (65/73) among...

There is concern about the zoonotic potential of rodent-borne hepatitis E virus, designated as HEV-C1. However, epizootiological information about HEV-C1 is limited. To address this issue, serum samples from 443 small mammals captured at 5 sites in Hanoi, Vietnam, were examined for anti-HEV-C1 IgG antibodies. In addition, livers of seropositive animals were examined for viral RNA. Anti-HEV-C1 a...

Human herpesvirus 8 (HHV-8) is a gamma-herpesvirus and etiological agent of all forms of Kaposi sarcoma (KS). Saliva may play an important role in HHV-8 transmission in specific populations. Little is known about HHV-8 oral shedding pattern and the possible correlation with the HHV-8 serological profile and viremia. A prospective study was conducted of HHV-8 salivary excretion among human immun...

OBJECTIVE To determine the prevalence, severity and pattern of intestinal parasitic infestation in HIV-seropositive patients. METHODS A Cross-sectional study from January 2007 to December 2008.Patients were recruited from the HIV clinics of the hospital. Paired blood and single stool specimens were collected from each patient. The stool sample was investigated for intestinal parasites while t...

Hepatitis C virus (HCV) transmission by both seropositive and seronegative cadaver organ donors has been documented, yet nucleic acid testing is not routinely used to identify active infection in these donors prior to transplantation. Between November 2001 and February 2004, we screened 1445 cadaver organ donors for anti-HCV antibodies with either HCV EIA-2.0 (Abbott Diagnostics, Chicago, IL, U...
