seroconversion

Immunology The development of antibodies detectable in the serum, after exposure to a particular organism or antigen, in a person who was previously immunologically 'naive' for–ie, previously unexposed to a particular antigen; seroconversion may indicate current infection–and transmissibility of a pathogen–eg, HIV-1–seroconversion to p24 and/or p41 antibody production or HBV–seroconversion to surface antibody-HBsAb or e antibody–HBeAb production. See Seropositive. Cf Seronegative.

se·ro·con·ver·sion

(sēr'ō-kŏn-vĕr'zhŭn)
The process by which, after exposure to the etiologic agent of a disease, the blood changes from a negative to a positive serum marker for that specific disease.

We calculated the attack rate of a recent HEV infection by dividing the number of seroconversions by the total number of participants still at risk for infection (i.e., all travelers who did not have HEV antibodies pretravel).
After another 3 weeks, ALT decreased to 456 U/L, AST to 375 U/L and bilirubin to 0.9 mg/dL, with undetectable HBV-DNA and HBe Ag to HBe Ab seroconversion, which was not, however, accompanied by clearance of HBsAg.
In 144 couples the index partner was taking combined ARVs; they accounted for over 7,000 unprotected acts of intercourse and 47 natural pregnancies but no HIV seroconversions (0 to 0.0005 per unprotected intercourse).
All the vaccines were immunogenic, although those prepared with strains 14 and 35, both typical strains, induced very low seroconversions. The highest seroconversion, 9.4, was induced by strain 26, an atypical strain, 70dpi (Figure 1).
In addition, after vaccination with seasonal TIV, no seroconversions to A/California/04/2009 virus were detected, whereas seroconversions to the seasonal vaccine strains were detected in 67%-100% of children.
The main outcome variable, time to seroconversion, was defined as the length of time between a participant's first clinic visit and the midpoint between the positive HIV test and the most recent negative test, plus one day.
Of those seven, three reported high-risk behavior after starting nPEP, so the seroconversion in these patients may not be entirely due to medication failure.
Check * 14 new cases and * 13 new cases 11 * 2 new cases in 2 seroconversions in the new new patient observed.
There were no seroconversions noted in any of the mothers or babies
SEATTLE -- Anticipatory prescribing of antiviral medications to high-risk men for postexposure prophylaxis may reduce the rate of HIV seroconversion, Dr.
If correct that translates to 892 new seroconversions in San Francisco, more than double the estimate reached at the last consensus meeting in 1997 and a marked increase over last year's interim estimate of 716 new infections per year.
A total of 27 children initially interpreted as having HBoV1 seroconversions had, on reassessment, HBoV2 or HBoV3 seroconversions (2).
