Low-level sequence variation in Toxoplasma gondii calcium-dependent protein kinases among different genotypes

J. L. Wang, Zhang, N. Z., Huang, S. Y., Xu, Y., Wang, R. A., and Zhu, X. Q., “Low-level sequence variation in Toxoplasma gondii calcium-dependent protein kinases among different genotypes”, vol. 14, pp. 4949-4956, 2015.

The causative agent of toxoplasmosis, Toxoplasma gondii, can infect virtually all nucleated cell types of warm-blooded animals. In this study, we examined the sequence variation in calcium-dependent protein kinase 2 (CDPK2) genes among 13 T. gondii strains from different hosts and geographical locations. The results showed that the lengths of the complete CDPK2 DNA and cDNA sequences were 3671-3673 and 2136 bp, respectively, and the sequence variation was 0-0.9% among different T. gondii strains.

 Prevalence and genotype distribution of human papillomavirus in women in the Henan Province

Y. - F. Zhi, Cha, X. - X., Li, X. - F., Qiu, C., and Rong, S. - H., “ Prevalence and genotype distribution of human papillomavirus in women in the Henan Province”, vol. 14, pp. 5452-5461, 2015.

We studied human papillomavirus (HPV) prevalence and genotype distribution among women in the Henan Province to provide epidemiological data as a means of preventing cervical cancer and developing a vaccine. A total of 14,873 samples were genotyped by using polymerase chain reaction reverse dot-blot. The overall HPV-positive rate in the sample was 23.98% (3566/14873), of which 69.01% (2461/3566) were infected with high-risk HPV types and 17.33% (618/3566) with low-risk types.
