BACKGROUND: One major consequence of economic development in South-East Asia has been a rapid expansion of rubber plantations, in which outbreaks of dengue and malaria have occurred. Here we explored the difference in risk of exposure to potential dengue, Japanese encephalitis (JE), and malaria vectors between rubber workers and those engaged in traditional forest activities in northern Laos PDR. METHODOLOGY/PRINCIPAL FINDINGS: Adult mosquitoes were collected for nine months in secondary forests, mature and immature rubber plantations, and villages...

Staphylococcus aureus is a very successful opportunistic pathogen capable of causing a variety of diseases ranging from mild skin infections to life-threatening sepsis, meningitis and pneumonia. Its ability to display numerous virulence mechanisms matches its skill to display resistance to several antibiotics, including β-lactams, underscoring the fact that new anti-S. aureus drugs are urgently required. In this scenario, the utilization of lytic bacteriophages that kill bacteria in a genus -or even species- specific way, has become an attractive field of study...

Intraamniotic infection, also known as chorioamnionitis, is an infection with resultant inflammation of any combination of the amniotic fluid, placenta, fetus, fetal membranes, or decidua. Intraamniotic infection is a common condition noted among preterm and term parturients. However, most cases of intraamniotic infection detected and managed by obstetrician-gynecologists or other obstetric care providers will be noted among term patients in labor. Intraamniotic infection can be associated with acute neonatal morbidity, including neonatal pneumonia, meningitis, sepsis, and death...

Chikungunya virus (CHIKV) is a re-emerging pathogen causing long-term polyarthritis and encephalitis. In conducting a preliminary investigation, we hypothesized that there is no serologic evidence of CHIKV infection among attendees of selected hospitals in Lagos and Osun States, Nigeria. Sera from 304 consecutively selected participants were screened for CHIKV IgG and IgM using ELISA. Findings were analyzed vis-à-vis participants' demographic and clinical data. Over 90.0% of the participants had never heard of CHIKV despite the fact that a large proportion of them (88...

BACKGROUND: Scrub typhus is a life-threatening disease, due to infection with O. tsutsugamushi, a Gram-negative bacterium that preferentially replicates in endothelial cells and professional phagocytes. Meningoencephalitis has been reported in scrub typhus patients and experimentally-infected animals; however, the neurological manifestation and its underlying mechanisms remain poorly understood. To address this issue, we focused on Orientia tsutsugamushi Karp strain (OtK), and examined host responses in the brain during lethal versus self-healing scrub typhus disease in our newly established murine models...

Tick-borne encephalitis poses a serious public health threat in the endemic regions. The disease treatment is restricted to symptomatic therapy, so great expectations are in the development of the prophylactic and therapeutic vaccines. The domain III of E protein of the tick-borne encephalitis virus is the main antigenic domain which includes virus-specific epitopes recognized by neutralizing antibodies. We have expressed, isolated and characterized the chimeric protein based on the fusion of domain III of E protein of the tick-borne encephalitis virus and bacterial porin OmpF from Yersinia pseudotuberculosis...

Seizure disorders are often associated with infectious etiologies. Infection, via the intracerebral (i.c.) route, of C57BL/6J mice with the Daniels (DA) strain of Theiler's murine encephalomyelitis virus (TMEV) results in approximately 50% of the mice developing acute behavioral seizures. TMEV-DA is the wild-type strain of the virus that replicates within the parenchyma of the brain. A variant of TMEV-DA, TMEV-H101, does not replicate within the parenchyma of the brain. However, infection with TMEV-H101 via the i...

BACKGROUND: Chikungunya fever is a globally spreading mosquito-borne disease that shows an unexpected neurovirulence. Even though the neurological complications have been a major cause of intensive care unit admission and death, to date, there is no systematic analysis of their spectrum available. OBJECTIVE: To review evidence of neurological manifestations in Chikungunya fever and map their epidemiology, clinical spectrum, pathomechanisms, diagnostics, therapies and outcomes...

In the swine industry, porcine reproductive and respiratory syndrome (PRRS) is a highly contagious disease which causes heavy economic losses worldwide. Effective prevention and disease control is an important issue. In this study, we described the construction of a Japanese encephalitis virus (JEV) DNA-based replicon with a cytomegalovirus (CMV) promoter based on the genome of Japanese encephalitis live vaccine virus SA14-14-2, which is capable of offering a potentially novel way to develop and produce vaccines against a major pathogen of global health...

Paper-based diagnostic devices have many advantages as a one of the multiple diagnostic test platforms for point-of-care (POC) testing because they have simplicity, portability, and cost-effectiveness. However, despite high sensitivity and specificity of nucleic acid testing (NAT), the development of NAT based on a paper platform has not progressed as much as the others because various specific conditions for nucleic acid amplification reactions such as pH, buffer components, and temperature, inhibitions from technical differences of paper-based device...

Neisseria meningitidis is a major cause of bacterial meningitis and sepsis worldwide. Capsular polysaccharide vaccines are available against meningococcal serogroups A, C, W and Y. More recently two protein based vaccines, Bexsero® and Trumenba®, have been licenced against meningococcal serogroup B strains; both vaccines contain meningococcal factor H binding protein (fHbp). fHbp is a surface exposed lipoprotein which binds the negative complement regulator, complement factor H (CFH), thereby inhibiting the alternative pathway of complement activation...

We describe a case of reproducible asystole during endovascular treatment of a posterior fossa dural arteriovenous fistula. Catheterisation of the posterior meningeal artery, a branch of the vertebral artery in this patient, followed by dimethyl sulfoxide injection prior to Onyx administration resulted in two episodes of asystole.To the best of our knowledge, this is the first reported case of asystole occurring during endovascular intervention in the posterior meningeal artery. This may represent a previously undescribed variant of the trigemino-cardiac reflex (TGCR) caused by chemical stimulation of small areas of trigeminally innervated posterior fossa dura...

Chikungunya virus is capable of affecting the nervous system of children and adults. We describe a case of sepsis and encephalitis triggered by this agent in a newborn whose mother developed symptoms of acute infection two days before delivery. Consequently, the infant had severe encephalitis that evolved with postnatal-onset microcephaly, bilateral optic atrophy, epilepsy and cerebral palsy.
