Acute hepatitis C infection with unclear route of transmission / Infección aguda de hepatitis C sin vía clara de trasmisión

A 43-year old man acquired acute hepatitis C virus (HCV) infection with unclear route of transmission. There were no known sexual or other risk factors for HCV acquisition. Phylogenetic analysis confirmed that the case was infected with identical genotype 1b strain. After symptomatic treatment for three weeks, the HCV was spontaneously cleared and liver function recovered.

Un hombre de 43 anos adquirió la infección del virus de la hepatitis aguda tipo C (VHC) por una via de trasmisión incierta. No habia ningún factor de riesgo sexual u otro conocido para la adquisición del VHC. El análisis filogenético confirmó que el caso se infectó con una cepa 1b de genotipo idéntico. Tras del tratamiento sintomático por tres semanas, el VHC se eliminó espontáneamente y lafunción del higado fue recuperada.

The utility of Mitochondrial DNA fragments for genetic identification of forensically important sarcophagid flies (Diptera: Sarcophagidae) in China

Abstract. Species-diagnostic anatomical characters of fleshflies are not known for most immature stages or even adults, and an existing key may be incomplete or difûcult for nonspecialists to use. The use of sarcophagids for PMI estimations has been greatly hampered by their highly similar morphological characters. DNA-based method can be used as a supplemental means of morphological method in identification of forensically important sarcophagid flies. However, relying solely on single DNA fragment for delimiting species is considered to be unreliable, especially when the fragment was small. Sequence data of selected regions of the cytochrome oxidase subunit two (COII) and 16S ribosomal RNA (16SrRNA) genes of the most important Chinese fleshfly taxa associated with cadavers are presented, which can be instrumental for implementation of the Chinese Sarcophagidae database. Phylogenetic analysis of the sequenced segments showed that all sarcophagid specimens were properly assigned into five species, which indicated the possibility of separation congeneric species with the short fragments.

Mitochondrial DNA and STR analyses for human DNA from maggots crop contents: A forensic entomology case from central-southern China

Insect larvae and adult insects found on human corpses can provide important forensic evidence however it is useful to be able to prove evidence of association. Without this, it could be claimed that the insect evidence was a contaminant or had been planted on the body. This paper describes how mitochondrial DNA (mtDNA) and STR analysis of the crop contents of larvae of the blowfly Aldrichina grahami collected from separated body parts was used to provide evidence of association.
