In Drosophila, the response against various microorganisms involves different recognition and signaling pathways, as well as distinct antimicrobial effectors. On the one hand, the immune deficiency pathway regulates the expression of antimicrobial peptides that are active against Gram-negative bacteria. On the other hand, the Toll pathway is involved in the defense against filamentous fungi and...
BACKGROUND At Driscoll Children's Hospital (Corpus Christi, Tex), we observed that most infants and children hospitalized for treatment of respiratory syncytial virus (RSV) bronchiolitis and/or pneumonia received broad-spectrum intravenous antibiotics despite having typical RSV signs and symptoms and positive RSV-rapid-antigen tests on admission. Physicians were concerned about the possibility ...
The level of procalcitonin is undetectable in healthy individuals and slightly increased in viral infections and noninfectious inflammatory responses. It has been described to be notably increased in bacterial, parasitic, or fungal infections. Procalcitonin has been reported to be a reliable marker for severe bacterial infections, although it has mainly been studied in specific entities or in s...
Bacterial infections are an important cause of sea otter (Enhydra lutris) mortality, and some of these infections may originate from terrestrial and anthropogenic sources. Antimicrobials are an important therapeutic tool for management of bacterial infections in stranded sea otters and for prevention of infection following invasive procedures in free-ranging otters. In this study, susceptibilit...
Ceftaroline is a novel cephalosporin recently approved in children for treatment of acute bacterial skin and soft tissue infections and community-acquired bacterial pneumonia (CABP) caused by methicillin-resistant Staphylococcus aureus, Streptococcus pneumoniae and other susceptible bacteria. With a favorable tolerability profile and efficacy proven in pediatric patients and excellent in vitro ...
Using the blood of 100 CFS patients and forensic polymerase chain reaction we have found that a majority of Chronic Fatigue Syndrome (CFS) patients show evidence of multiple, systemic bacterial and viral infections (OR = 18.0, 95% CL 8.5-37.9, P < 0.001) that could play an important role in CFS morbidity. CFS patients had a high prevalence (51%) of one of four Mycoplasma species (OR = 13.8, 95%...
BACKGROUND Bacterial infections remain a major threat and a leading cause of death worldwide. Most of the bacterial infections are caused by gram-positive and negative bacteria, which are recognized by Toll-like receptor (TLR) 2 and 4, respectively. Activation of these TLRs initiates multiple pathways that subsequently lead to effective immune response. Although, both the TLRs share common sign...
AIMS/BACKGROUND To determine the epidemiological characteristics and risk factors predisposing to corneal ulceration in Madurai, south India, and to identify the specific pathogenic organisms responsible for infection. METHODS All patients with suspected infectious central corneal ulceration presenting to the ocular microbiology and cornea service at Aravind Eye Hospital, Madurai, from 1 Janu...
Background and Objective: Bacterial exposure in hospitals due to the presence of pathogens in hospitals is one of important health problems for medical staff. The World Health Organization (WHO) reported a global outbreak of hospital infections from 5.7% to 19.1% in the 2011 report. The aim of this study was to identify bacterial bioaerosols in nursing stations in a public hospital in Tehran to...
BACKGROUND Broad-range 16S ribosomal RNA (rRNA) gene polymerase chain reaction (PCR) is used for detection and identification of bacterial pathogens in clinical specimens from patients with a high suspicion for infection. However, prospective studies addressing the impact and clinical value of broad-range bacterial 16S rRNA gene amplification for diagnosis of acute infectious diseases in nonsel...
