Equine coital exanthema (ECE), caused by equid herpesvirus 3 (EHV-3), has been recognized as an economically significant venereal disease for years. However, no infection models on the natural host have been established. In order to set up an experimental infection protocol, seronegative and seropositive mares were topically inoculated in the perineal region with 4 × 10(6)TCID(50)/ml of EHV-3. ...

Seventeen of 73 (23.3%) multiply transfused patients with thalassaemia major (age range, 1-39 years) tested positive for antibody to hepatitis C virus (anti-HCV). Eleven of the 24 patients regularly transfused in countries outside Britain were anti-HCV seropositive; only six of the 49 regularly transfused in Britain were seropositive. The incidence of anti-HBs and anti-HBc was similar to that o...

OBJECTIVES Symptomatic cytomegalovirus (CMV) infection can cause significant morbidity and occasional mortality after liver transplantation. In a previous audit, we showed that donor CMV seropositivity (D+) was a risk factor for symptomatic infection, and we estimated the likely clinical and financial impact of 14 weeks of oral ganciclovir prophylaxis given to recipients of CMV-seropositive org...

We investigated the frequency, site, and risk factors for herpes simplex virus (HSV) shedding in 30 human immunodeficiency virus (HIV)-negative HSV type 2 (HSV-2)-seropositive men who have sex with men. Subjects collected daily HSV culture samples from genital, perianal, and oral areas for 100 days and maintained diaries of signs and symptoms. Sixteen men (53.3%) shed HSV-2, and 9 (56.3%) of 16...

IntroductionIn 2012 a large epidemic of pertussis occurred in the Netherlands. We assessed pertussis toxin (PT) antibody levels in longitudinal serum samples from Dutch 10-18 year-olds, encompassing the epidemic, to investigate pertussis infection incidence. Methods: Blood was sampled in October 2011 (n = 239 adolescents), then 1 year (2012; n = 228) and 3 years (2014; n = 167) later. PT-IgG co...

BACKGROUND Cryptosporidium parvum, the protozoan parasite, causes a significant enteric disease in immunocompromised hosts such as HIV patients. The present study was aimed to compare serum IgG, IgM and IgA responses to crude soluble antigen of C. parvum in HIV seropositive and seronegative patients co-infected with Cryptosporidium and to correlate the responses with symptomatology. METHODS C...

OBJECTIVE To develop a set of comprehensive, standardized, evidence-based guidelines for the use of antiviral therapy to prevent cytomegalovirus disease in adult patients having undergone renal transplantation. OPTIONS The use of medication, at the time of induction therapy or at the earliest sign of viremia. Treatments were evaluated by patient and donor serologic groups and the induction re...

The present work was conducted to study the seroprevalence of Salmonella, Mycoplasma gallisepticum (MG), and Mycoplasma synoviae (MS) infection in backyard chickens located in Entre Ríos, Argentina, over 3 periods of time. A total of 2,441 sera samples were collected from backyard chickens belonging to 256 family farms in 16 counties in the state of Entre Ríos from January to May 2003 (first pe...

Helicobacter pylori antibodies were measured over 24 months in American Indian and Alaska Native persons who cleared their infections. Two months after treatment, 82% of H. pylori-negative persons remained seropositive. While there were declines in H. pylori antibodies for 12 months, after 24 months 71% of persons remained seropositive.
