BACKGROUND Although sapovirus (SaV) has been detected in 2.2-12.7% of gastroenteritis cases globally, there are limited data on SaV epidemiology. OBJECTIVES Describe the epidemiology, clinical characteristics and factors associated with SaV gastroenteritis in hospitalised children <5 years of age in South Africa. STUDY DESIGN Between 2009 and 2013 during prospective diarrhoeal surveillance,...
BACKGROUND From 31 August to 9 September 2015, a total of 150 military personnel at a military institution in Singapore were infected with acute gastroenteritis (AGE) with an attack rate of approximately 3%. This study aimed to determine the epidemiology of the outbreak, investigate its origins, and discuss measures to prevent future occurrences. METHODS After the AGE outbreak was declared on...
minimum of 10 d. Patients should be retested for ongoing viral secretion every 5 d and negative results confi rmed with a follow-up sample after 48 h. Classic virus isolation in addition to molecular methods may also identify potentially infectious patients. Prophylactic neuraminidase inhibitor use in such patients also needs to be addressed. Resistance is more likely with the reduced prophylac...
Sapovirus (SaV) protease catalyzes cleavage of the peptide bonds at six sites of a viral polyprotein for the viral replication and maturation. However, the mechanisms by which the protease recognizes the distinct sequences of the six cleavage sites remain poorly understood. Here we examined this issue by computational and experimental approaches. A structural modeling and docking study disclose...
Antibodies to B. melitensis were detected by agglutination by using the Rose Bengal and Brucella Wright tests (both from BioRad, Hercules, CA, USA). Of the 63 patients, 9 had a positive antibody response against a tested antigen (Table): 1 to phase I C. burnetii and 8 to Bartonella spp. (IgG >200). Of these, 7 had a 1-fold dilution higher titer to B. quintana than to B. henselae, including 1 wi...
