Synthetic p55 tandem DNA vaccine against Pneumocystis carinii in rats.

Pneumocystis spp. are opportunistic fungal pathogens that are closely associated with severe pneumonia and pulmonary complications in patients with impaired immunity. In this study, the antigenic epitopes of the gene encoding the 55 kDa antigen fragment of Pneumocystis (p55), which may play an important role in Pneumocystis pneumonia, were analyzed.

Two cases of human thelaziasis as confirmed by mitochondrial cox1 sequencing in China.

Two special cases of human thelaziasis were reported in China: an old farmer with heavy infection by 36 worms and a 7-year-old boy with infection by eight worms. Thelazia callipaeda was morphologically identified and confirmed by mitochondrial cox1 gene sequencing.
