Some production parameters of seropositive cows (age, first calving age, 305 day mature equivalent last milk yield production, lifetime mature equivalent milk yield production, lifetime total milk production, lifetime total milking period, lifetime monthly milk production, lifetime daily milk production, lifetime total days of milking, number of inseminations per pregnancy (for last pregnancy),...

Patient MV serological status remains an important factor for the outcome of allogeneic stem cell transplantation (SCT). CMV seronegative patients receiving a graft from a seronegative donor have lower transplant-related mortality. In a previous study using the EBMT registry, we found that CMV seropositive patients receiving grafts from seropositive unrelated donors had improved survival and re...

BACKGROUND There is paucity of published data on human immunodeficiency virus (HIV) seroprevalence among migrant workers entering Middle-East particularly Kuwait. We took advantage of the routine screening of migrants for HIV infection, upon arrival in Kuwait from the areas with high HIV prevalence, to 1) estimate the HIV seroprevalence among migrant workers entering Kuwait and to 2) ascertain ...

We examined incidence and correlates of progression and regression of abnormal cervical cytologic test results, defined as at least low-grade squamous intraepithelial lesions (SILs), in 774 human immunodeficiency virus (HIV)-seropositive and 391 HIV-seronegative women monitored semiannually for up to 5.5 years. During follow-up, 224 (35%) HIV-seropositive women and 34 (9%) HIV-seronegative wome...

brucellosis has remained a great problem of health in most of countries, which have failed in control of zoonosis infections. this disease is caused by species of brucella and usually is transferred from animals to humans. the purpose of this study was to investigate the seroprevalence of brucellosis among animal farmers of yazd province. in this descriptive study, 933 animal farmers were inves...

RATIONALE Policy recommendations on contact investigation of HIV-seropositive patients with tuberculosis have changed several times. Current epidemiologic evidence informing these recommendations is considered low quality, and few large studies investigating the infectiousness of HIV-seropositive and -seronegative index cases have been performed in sub-Saharan Africa. OBJECTIVES We assessed t...

BACKGROUND Clinical features of pandemic H1N1 have been derived from lab-confirmed, hospitalized, or critically ill subjects. This report describes the clinical features of H1N1 and their prevalence from non-confirmed subjects according to seroprevalence status in México. The objective was to determine the prevalence of these clinical features from non-confirmed cases of pandemic H1N1 and to c...

OBJECTIVE To determine the sex and age distribution of aquaporin-4 (AQP4) autoimmunity using data derived from clinical service laboratory testing of 56,464 patient samples. DESIGN Observational analysis. SETTING Mayo Clinic Neuroimmunology Laboratory. PATIENTS Between October 1, 2005, and January 4, 2011, 56,464 patients were tested for AQP4-IgG; 2960 (5.2%) patients were seropositive. ...

INTRODUCTION Since 1970, lengthening of the rectosigmoid has been suspected to be a solitary manifestation of Chagas colopathy. METHODS To test this hypothesis, opaque enema was administered on 210 seropositive and 63 seronegative patients, and radiographs in the anteroposterior and posteroanterior positions were examined blind to the serological and clinical findings. The distal colon was me...
