Seasonality and outbreak of a predominant Streptococcus pneumoniae serotype 1 clone from The Gambia: expansion of ST217 hypervirulent clonal complex in West Africa. [PDF]

, 2008
BACKGROUND: Streptococcus pneumoniae serotype 1 causes > 20% of invasive disease, among all age groups combined, in The Gambia. In contrast, it is rarely detected in carriage studies. This study compares the molecular epidemiology of S.

Exchange of the C-terminal part of VP3 from very virulent infectious bursal disease virus results in an attenuated virus with a unique antigenic structure [PDF]

, 2002
Infectious bursal disease virus (IBDV) is the major viral pathogen in the poultry industry. Live attenuated serotype 1 vaccine strains are commonly used to protect susceptible chickens during their first 6 weeks of life. Wild-type serotype 1 IBDV strains

Serotypes of bovine astrovirus [PDF]

Journal of Clinical Microbiology, 1985
Three isolates of bovine astrovirus, one from the United Kingdom and two from the United States, possessed common antigens by immunofluorescence and strain-specific antigens by neutralization and were designated as two, and probably three, distinct serotypes.

Increased Risk for Group B Streptococcus Sepsis in Young Infants Exposed to HIV, Soweto, South Africa, 2004–2008

Emerging Infectious Diseases, 2015
Although group B Streptococcus (GBS) is a leading cause of severe invasive disease in young infants worldwide, epidemiologic data and knowledge about risk factors for the disease are lacking from low- to middle-income countries.
