The gut microflora assay in patients with colorectal cancer: in feces or tissue samples?
Authors: Rezasoltani S, Dabiri H, Asadzadeh-Aghdaei H, Sepahi AA, Modarressi MH, Nazemalhosseini-Mojarad E Abstract Gut microbiota is the complex community of microorganisms that live in the digestive tracts of humans and other animals, including insects. The relationship between gut microbiota and human health is mutualistic and altered bacterial compositions in fecal and mucosal specimens of colon in patients with cancer compared to healthy subjects were observed. Thereby, studying the gut microbiota, their interactions with the host and their alterations in colorectal cancer (CRC) patients could be helpful to di...

Homogeneity of Mycoplasma agalctiae vaccine strains in an agalaxy- high-burden environment.
Conclusion: In explanation, lack of efficient disease control measures, has possibly contributed in evolution of a clone or a few clones that gradually overwhelmed the population over the time. Besides, the similarity between the Iranian and the PG2 strains, might be due to homoplasy or farming exercises such as animal importation. Inclusion of further local isolates in next studies will help to assess these assumptions. PMID: 30996831 [PubMed] (Source: Iranian Journal of Microbiology)

The frequency of Epstein-Barr virus among hemodialysis patients, Ahvaz, Iran.
Conclusion: Our study results showed that high prevalence of anti-EBV (VCA) IgG antibody (96.42%) were observed among the HD patients. Although the status of EBV latency was not performed, but it seems many of these patients are at risk of EBV-reactivation during the organ transplantation. As a result, it is recommended that the detection of EBNA-1 gene as a marker of EBV latency should be implemented for all HD patients to prevent EBV reactivation during organ transplantation.
