Understanding speciation hinges on understanding how reproductive barriers arise between incompletely isolated populations. Despite their crucial role in speciation, prezygotic barriers are relatively poorly understood and hard to predict. We use two closely related cricket species, Gryllus bimaculatus and G. campestris, to experimentally investigate(More)
Reproductive barriers reduce gene flow between populations and maintain species identities. A diversity of barriers exist, acting before, during and after mating. To understand speciation and coexistence, these barriers need to be quantified and their potential interactions revealed. We use the hybridising field crickets Gryllus bimaculatus and G.(More)
INTRODUCTION Pneumonia is the most lethal infection in nursing homes. The Infectious Disease Society of America recommends that attempts be made to obtain quality sputum to focus antibiotic therapy. This is especially important within the enclosed space of a nursing home, where constant pressure from broad spectrum, empiric antibiotics sets the stage for(More)
OBJECTIVE Antibiotic exposure is a risk factor for isolation of methicillin-resistant Staphylococcus aureus (MRSA). We reasoned that this relationship might be especially strong if the comparison was targeted to antibiotics with activity against methicillin-sensitive Staphylococcus aureus (MSSA), but not MRSA. SUBJECTS Forty-eight cases with initial MRSA(More)
BACKGROUND Methicillin-resistant Staphylococcus aureus (MRSA) generates concern in nursing homes. Restrictive isolation precautions may be applied for indefinite periods. Adverse events driving these concerns include transmission and infection. METHODS The 721-bed Wisconsin Veterans Home in King performs approximately 645 cultures annually. The site,(More)
