OBJECTIVE To identify risk factors for the first episode of Klebsiella Pneumonia resistant to carbapenems (KPRC) infection in critically ill patients. DESIGN, SETTING, AND METHODS This prospective cohort study was conducted in a 12-bed general Intensive Care Unit (ICU) in a University Hospital on ICU patients who required mechanical ventilation (MV) for >48 hours during a 12-month period. Cli...

During her lifetime, an adult woman has a 50% chance of developing a urinary tract infection—one of the most common types of infections (1). Most urinary tract infections are caused by strains of the bacterium Escherichia coli, and, for the most part, are easily treated with antibiotics. However, many of these infections become chronic or recurrent because of increasing antibiotic resistance an...

Persistent infection (PI) of YAC-1 cells by coxsackievirus B3 (CBV-3) was characterized. CBV-3 PIs were maintained for 7 months or more, although in two other cases cells were cured of virus at 6 and 6.5 months of PI. The titre of infectious virus peaked during the first week of the infection and then gradually decreased. The proportion of cells producing infectious centres increased to 100% by...

In African endemic area, adults are less vulnerable to cerebral malaria than children probably because of acquired partial immunity or semi-immune status. Here, we developed an experimental cerebral malaria (ECM) model for semi-immune mice. C57BL/6 (B6) mice underwent one, two and three cycles of infection and radical treatment (1-cure, 2-cure and 3-cure, respectively) before being finally chal...

persons infected with the human immunodeficiency virus (hiv) are particularly susceptible to tuberculosis, either by latent infection reactivation or by a primary infection with rapid progression to active disease. this study was done to determine the frequency of tuberculosis infection among iranian patients with hiv/aids. a total of 262 hiv/aids patients attending all three hiv/aids health ca...

We review the basic properties of the different supernova types identified in the current taxonomy, with emphasis on the more recent developments. To help orienting in the variegate zoo, the optical photometric and spectroscopic properties of the different supernova types are presented in a number of summary figures. We also report the latest estimates of the supernova rates and stress the need...

Quantities of free amino acids in segments of cotton roots resistant and susceptible to Meloidogyne incognita were compared. Following infection, the root-knot susceptible cultivar, M8, had greater percentage increases of certain individual free amino acids than the resistant cultivar, Clevewilt, but the sum total of free amino acids was greatest in the resistant cultivar. More free amino acids...

The role of transforming growth factor beta (TGF-beta) in infection with Plasmodium chabaudi was investigated with resistant and susceptible mouse models. C57BL/10 mice produced gamma interferon (IFN-gamma) and nitric oxide (NO) shortly after infection and cleared the parasite spontaneously. In contrast, BALB/c mice showed a transient enhancement of TGF-beta production, followed by a relative l...

Rabbits have low susceptibility to prion infection. Studies on prion protein (PrP) from animal species of different susceptibility to prion diseases identified key amino acid residues, specific motif, and special features in rabbit prion protein (RaPrP(C)) that contribute to the stability of rabbit PrP(C) and low susceptibility to prion infection. However, there is no evidence showing that rabb...
