A seroepidemiologic study of prevalence of antibody to cytomegalovirus (CMV) was simultaneously done in four populations: group I, nuns working as nurses or school teachers; group II, women admitted to a upper socioeconomic private hospital; group III, women admitted to a lower socioeconomic county hospital, and group and IV women attending a veneral disease clinic. Groups II, III and IV, were ...

The Bovine Viral Diarrhea (BVD) and the Infectious Bovine Rinotraqueitis (IBR) are two diseases of viral etiology, highly contagious, of easy transmission and of wide distribution through out the world . The reproductive loses may well be the principal consequence associated with the infection by these agents as they are two of the main diseases that affect reproduction all over the most import...

Background: Multiple sclerosis (MS) is a chronic, demyelinating disease of the CNS in which autoimmunity to myelin plays a role in pathogenesis. Infection with common viruses, particularly EpsteinBarr virus (EBV), is postulated to contribute to the pathobiology of MS. Epidemiological studies suggest an association between infection with EBV and risk of MS. To characterize the IgG antibody to th...

E. risticii, the cause of classic Potomac horse fever, is now known to produce two disease syndromes: EEC and EEA. The pathogen appears to commonly infect horses based on seroepidemiologic studies; however, the method of transmission remains unknown. The most common clinical disease is EEC, commonly called Potomac horse fever, which presents a wide spectrum of clinical signs. Diagnosis is curre...

Studies are difficult in areas lacking modern facilities due to the inability to reliably collect, store, and ship samples. Thus, we sought to evaluate the use of a dry plasma collection device for seroepidemiology studies. Plasma was obtained by fingerstick using a commercial dry plasma collection device (Chemcard Plasma Collection Device) and serum (venipuncture) from individuals in Kazakhsta...

In March 2020, several mass gathering events were related to the Falles festival in Borriana (Spain), resulting a 536 laboratory-confirmed COVID-19 cases outbreak among participants. This article estimates anti-SARS-CoV-2 antibodies persistence six months after and factors associated with antibody response. A prospective population-based cohort study was carried out by Public Health Centre of C...
