Streptococcus milleri species are found in normal oral flora, upper respiratory tract, gastrointestinal tract, and they have also been isolated from vagina. S. milleri organisms are associated with pyogenic infections and they either result in isolated infections or are a part of mixed pyogenic infections. Most commonly, they are associated with dental and periodontal abscess, nasopharyngeal in...
Infections with the malaria parasite Plasmodium falciparum typically comprise multiple strains, especially in high-transmission areas where infectious mosquito bites occur frequently. However, little is known about the dynamics of mixed-strain infections, particularly whether strains sharing a host compete or grow independently. Competition between drug-sensitive and drug-resistant strains, if ...
The simultaneous inoculation of influenza A and B strains into eggs was found to result in the formation of virus which had antigenic properties of both parent strains. The hemagglutinin of the new virus could be inhibited by both A and B antisera and the agent was also neutralized by both sera. This X particle displayed the characteristics of what we have previously called X(1). It did not rep...
Simultaneous infections with multiple fungi may be misinterpreted as monomicrobial infections by current diagnostics with ramifications for the choice of antimicrobial agents that may impact patient outcomes. The application of molecular methods on tissue samples may be useful to decipher the aetiology of mixed fungal infections. We present a leukaemic patient who died from sepsis due to candid...
Introduction: Identifying and reporting nosocomial infections are at the center of attention of healthcare. The present study was carried out to study the problems of the National Nosocomial Infections Surveillance System (NNIS). Methods: This mixed (Qualitative- Quantitative) descriptive study was performed in 2011. In the qualitative section, after a semi- structured interview,...
BACKGROUND In malaria endemic regions people are commonly infected with multiple species of malaria parasites but the clinical impact of these Plasmodium co-infections is unclear. Differences in transmission seasonality and transmission intensity between endemic regions have been suggested as important factors in determining the effect of multiple species co-infections. PRINCIPAL FINDINGS In ...
Bacterial whole genome sequencing offers the prospect of rapid and high precision investigation of infectious disease outbreaks. Close genetic relationships between microorganisms isolated from different infected cases suggest transmission is a strong possibility, whereas transmission between cases with genetically distinct bacterial isolates can be excluded. However, undetected mixed infection...
BACKGROUND The role of respiratory viral infections (RVIs) as a cause of overall fever and neutropenia (FN) episodes in children with cancer has been less characterized than bacterial infections. We conducted a study aimed to determine the frequency of RVI in children with low compared with high risk for invasive bacterial infection (IBI) FN episodes and compare the clinical outcome of RVI and ...
BACKGROUND This analysis assessed the acquisition (incidence) and persistence (clearance) of human papilloma virus (HPV) infection by self-reported race among men in The HPV in Men (HIM) Study, a multinational prospective study of the natural history of genital HPV infections. METHODS Self-reported race was categorized as White, Black, Asian/Pacific Islander (PI), or multiple and mixed race. ...
