Antibiotic-resistant Escherichia coli isolated from urban rodents in Hanoi, Vietnam.

Antimicrobial resistance (AMR) is a global public health concern for both clinical and veterinary medicine. Rodent feces are one of the major infectious sources of zoonotic pathogens including AMR bacteria. So far, there are limited studies reported focused on Escherichia coli isolated in rodent feces from rural and suburban areas in Vietnam.

Molecular epidemiology of Leptospira interrogans in Rattus norvegicus in Hanoi, Vietnam.

Leptospirosis is a zoonotic disease that is caused by pathogenic spirochaetes of Leptospira spp. and it has become a public health concern in urban localities in the tropics. Rats are important reservoir animals for the transmission of leptospirosis in urban areas.

Dengue virus infection-enhancement activity in neutralizing antibodies of healthy adults before dengue season as determined by using FcγR-expressing cells.

Background: Antibodies are critical responses to protect the host from dengue virus(DENV) infection. Antibodies target DENV by two pathologic mechanisms: virus neutralization and infection enhancement. In dengue patients, the absence of neutralizing activity in the presence of FcγR implies that infection-enhancing activity hampers the neutralizing activity of antibodies, which could potentially lead to symptomatic presentations and severe clinical outcomes.

Evaluation of Rapid Neutralizing Antibody Detection Test against Rabies Virus in Human Sera.

Rapid and easy determination of protective neutralization antibody (NAb) against rabies in the field is very important for an early and effective response to rabies in both animal and human health sectors. The rapid neutralizing antibody detection test (RAPINA), first developed in 2009 and then improved in 2012, is a quick test allowing detection of 0.5 IU/ml antibodies in human and animal sera or plasma.
