We tested the frequency of occult hepatitis B infection (OBI) among Egyptian healthcare workers (HCWs). We tested 132 HCWs for hepatitis B virus (HBV) DNA by nested polymerase chain reaction (PCR), and hepatitis C virus antibody (anti-HCV) by ELISA. HCV RNA was measured by nested PCR in anti-HCV-positive HCWs. HBV-DNA-positive HCWs were subjected to HBV genotyping. We included 132 HCWs who were...
27 Diagnosis of Post Kala-azar dermal leishmaniasis (PKDL), particularly the macular form is 28 difficult by microscopy. This study compared the positivity of nested polymerase chain reaction 29 (91.9%) with imprint smear microscopy (70.9%) in 62 PKDL samples. Nested PCR, showing 87.5% 30 positivity in macular lesions compared to 41.6% by imprint smear microscopy, is an efficient method 31 for ...
We developed a sensitive nested polymerase chain reaction procedure for the Cryptosporidium oocyst wall protein (COWP) gene. Amplification and genotyping were successful in 95.2% of 1,680 fecal samples, 77.6% by the unnested and 17.6% by the nested COWP procedure. The COWP gene was amplified from 2,128 fecal samples: 71 from livestock animals and 2,057 from humans. This series included 706 case...
