ABSTRACT The human body plays host to a wide variety of microbes, commensal and pathogenic. In addition to interacting with their host, different microbes, such as bacteria and viruses, interact with each other, sometimes in ways that exacerbate disease. In particular, gene expression of a number of viruses, including Kaposi's sarcoma-associated herpesvirus (KSHV), Epstein-Barr virus (EBV), and...

Worldwide the entire human population is at risk of infectious diseases of which a high degree is caused by pathogenic protozoans, worms, bacteria, and virus infections. Moreover the current medications against pathogenic agents are losing their efficacy due to increasing and even further spreading drug resistance. Therefore, there is an urgent need to discover novel diagnostic as well as thera...

Background: Microbial biofilms are responsible for many human infections and increase of antibiotic resistant bacteria. Therefore, finding an efficient way to prevent infection and biofilm formation of bacteria is essential. Medicinal plants are among suitable candidates to inhibit biofilm formation of bacteria. The aim of this study was to evaluate the antimicrobial effects of...

A transmissible agent (AHA) causing ascites and hepatitis in mice has been described. No known pathogenic bacteria, fungi, protozoa, leptospira, rickettsia, or viruses have been demonstrated in the infected mice. AHA does not pass through a Seitz filter and differs in most respects from the agents previously described which produce hepatitis in mice.

Abstract Background Bacteria and respiratory viruses co-occur in the nasopharynx, their interactions may impact pathogenesis of invasive disease. Associations bacteria nasopharynx be affected by HIV. Methods We conducted a nested case-control study from larger cohort banked nasopharyngeal swabs families with without HIV West Bengal India, to look at association parents children when they are as...

Microbial DNA in the cytosol induces production of interferon-beta (IFN-beta) and an innate immune response. Chiu et al. (2009) now implicate cytosolic DNA-dependent RNA polymerase III as the DNA sensor linking DNA release by pathogenic bacteria and viruses in the host cell cytosol to IFN-beta production and innate immunity.

From a series of tests covering 15 months, another instance is recorded of the detection of the virus of poliomyelitis in urban sewage. It has not yet been possible to detect the virus of poliomyelitis in sewage during non-epidemic periods. It is likely that the periodic sampling of sewage for pathogenic viruses or bacteria may be a method of epidemiological value.

conclusions these human-derived lab and bifidobacteria exhibited different mechanisms involved in pathogenic inhibition. therefore a combination of these probiotic strains could be a great promise and possibility for the development of probiotic products to effectively prevent and control food-borne infection in humans. background food-borne pathogens are among the most significant problems in ...

Covid-19 detection in food is an effective solution to ensure the accurate rate of Covid-19. The difficulties and methods virus safety feasibility digital PCR technology are analyzed. main parameters characteristics dPCR other technologies compared. application viruses pathogenic bacteria, preparation purity verification RNA reference material, steps testing were expounded. Compared with tradit...
