PCV2 (Porcine circovirus type 2) is considered as the essential infectious agent of PMWS (post weaning multisystemic wasting syndrome) in pigs. Serological studies have shown that the virus is ubiquitous. Currently, there are many reports about the epidemiology and genetic characteristics of this virus around the world, but in Mexico it has not been studied. More than 3,500 samples of serum, rectal swabs, tissues and semen of 34 Mexican porcine farms from 10 important producer regions were analyzed by PCR. Results show that 97% of the farms were positive. Both genotypes, PCV2a and PCV2b were detected. It also found that the most prevalent genotype in Mexico is PCV2b. Regarding to amino acid sequence; three major heterogenic regions were present in the positions 59-91, 123-136 and 185-210.

The most appropriate treatment for Klatskin tumor(KT)with a curative intention is multimodal therapy based on achieving resection with tumour-free margins(R0resections)combined with other types of neoadjuvant or adjuvant treatment(the most important factor affecting KT survival is the possibility of R0 resections,achieving 5-year survival rate of 40%-50%).Thirty to forty percent of patients with KT are inoperable and present a 5-year survival rate of 0%.In irresectable non-disseminated KT patients,using liver transplantation without neoadjuvant treatment,the 5-year survival rate increase to 38%,reaching 50%survival in early *** selected cases,with liver transplantation and neoadjuvant treatment(chemotherapy and radiotherapy),the actuarial survival rate is 65%at 5 years and 59%at 10 *** conclusion,correct staging,neoadjuvant treatment,living donor and priority on the liver transplant waiting list may lead to improved results.
