Although severe fever with thrombocytopenia syndrome (SFTS) was first reported from Japan in 2013, the precise clinical features and the risk factors for SFTS have not been fully investigated in Japan. Ninety-six cases of severe fever with thrombocytopenia syndrome (SFTS) were notified through the national surveillance system between April 2013 and September 2014 in Japan. All cases were from western Japan, and 82 cases (85%) had an onset between April and August. A retrospective observational study of the notified SFTS cases was conducted to identify the clinical features and laboratory findings during the same period...

Zika virus (ZIKV) is a flavivirus related to the Dengue, yellow fever and West Nile viruses. Since the explosive outbreaks of ZIKV in Latin America in 2015, a sudden increase in the number of microcephaly cases has been observed in infants of women who were pregnant when they contracted the virus. The severity of this condition raises grave concerns, and extensive studies on the possible link between ZIKV infection and microcephaly have been conducted. There is substantial evidence suggesting that there is a causal link between ZIKV and microcephaly, however, future studies are warranted to solidify this association...

BACKGROUND: Malaria is an important cause of death and illness in children worldwide. Most cases of neonatal malaria are misdiagnosed because of the lack of specific symptoms and a general lack of awareness. Nothing much is known in literature about the haematological changes during malaria infection and outcome of disease in neonates. Neonatal malaria is an underdiagnosed entity. So this hospital based observational study aims to assess diagnostic features of neonatal malaria. METHODS: From August 2004 to August 2013, information of all slide positive for malaria cases aged 0 to 28 days admitted to our pediatric hospital was collected and analysed...

HBoV is an emergent virus, which is frequently detected as a co-infective agent. However, it can cause disease on its own. It is associated with respiratory and diarrhoeal illness in children and adults, whether immunocompetent or immunocompromised. We report HBoV infection in a child post-liver transplantation, who presented with persistent fever and mild tachypnea, 3 weeks after a successful transplant. She recovered spontaneously with no graft dysfunction.

BACKGROUND: Dengue fever is caused by four related RNA viruses of the genus Flavivirus, dengue virus (DENV)-1, -2, -3, and -4, which are transmitted to humans by mosquitoes. Although DENV is not endemic in Japan, an autochthonous dengue outbreak occurred in 2014. Several transfusion-transmitted cases have also been reported after the use of blood and plasma products in DENV-endemic countries. The aim of this study was to develop a novel multiplex reverse transcription-polymerase chain reaction (RT-PCR) assay for DENV blood screening...

We present a case of acute hemolytic anemia, renal failure, and Clostridium perfringens bacteremia in a patient with acute myelogenous leukemia. The high fatality of C. perfringens bacteremia requires that clinicians recognize and rapidly treat patients at risk for this infection. Although other hemolytic processes are in the differential diagnosis of these events, the presence of high fever, chills, and rapidly positive blood cultures may help narrow the diagnosis. Most cases of C. perfringens bacteremia have a concomitant coinfection, which makes broad spectrum empiric therapy essential...

A 55-year-old woman was diagnosed with aseptic meningitis at the age of 43 and 44. She developed sudden fever and headache, and she showed nuchal rigidity. Cerebrospinal fluid examination revealed pleocytosis (cell count 208/mm(3)) and was positive for herpes simplex virus type 2 (HSV-2) DNA by PCR. Acyclovir was started on the first day of admission, and she was complete recovery. Preserved cerebrospinal fluid specimen from aseptic meningitis at the age of 44 was also positive for HSV-2 DNA by PCR. She was diagnosed with HSV-2 associated recurrent aseptic meningitis (Mollaret's meningitis) with a recurrence after 11-year interval...

Amblyomma maculatum Koch (Acari: Ixodidae), the primary vector for Rickettsia parkeri, may also be infected with a rickettsia of unknown pathogenicity, "Candidatus Rickettsia andeanae." Infection rates with these rickettsiae vary geographically, and coinfected ticks have been reported. In this study, infection rates of R. parkeri and "Ca R. andeanae" were evaluated, and rickettsial DNA levels quantified, in 335 questing adult A. maculatum collected in 2013 (n = 95), 2014 (n = 139), and 2015 (n = 101) from Oktibbeha County, MS...

The RNA modification N6-methyladenosine (m(6)A) post-transcriptionally regulates RNA function. The cellular machinery that controls m(6)A includes methyltransferases and demethylases that add or remove this modification, as well as m(6)A-binding YTHDF proteins that promote the translation or degradation of m(6)A-modified mRNA. We demonstrate that m(6)A modulates infection by hepatitis C virus (HCV). Depletion of m(6)A methyltransferases or an m(6)A demethylase, respectively, increases or decreases infectious HCV particle production...

Kidney transplant recipients are at increased risk of developing clinical disease due to uncommon opportunistic viral pathogens. Refractory anemia is classically associated with parvovirus B19 infection. West Nile virus has the propensity to cause fever and neurologic symptoms, while spastic paresis and lymphoma can be triggered by human T cell lymphotrophic virus. In this review article, the epidemiology, clinical manifestations, diagnosis and treatment of less common viruses are discussed in the setting of kidney transplantation...

We enrolled 75 consecutive infants presenting with history of first seizure at a tertiary care hospital in New Delhi, India. Clinical and biochemical work-up for etiology, and electroencephalography were performed in all infants. Developmental assessment was done 3-month after discharge. 72% had generalized seizures, and fever was the commonest co-morbidity (57.3%). 68% had provoked seizures, mainly due to hypocalcemia (34.3%) or neuro-infections (29.3%). Seven (9.3%) infants died during hospital stay; mostly those with neuro-infections...

OBJECTIVES: To evaluate the vaccine coverage of psoriasis patients prior to initiating or changing immunosuppressant therapy, and to verify that the prescribed vaccines have been administered. PATIENTS AND METHODS: We conducted a bi-centre, observational, cross-sectional study over 9 months. Psoriasis patients in whom immunosuppressant therapy (comprising cyclosporine, methotrexate, etanercept, infliximab, adalimumab or ustekinumab) was indicated were included. Medical history, previous treatments, vaccination status, viral serology results (for hepatitis B, measles, and chickenpox), and reasons for non-vaccination were assessed via questionnaire...

Coxiella (C.) burnetii is the etiological agent of the zoonotic disease known a Q fever. This agent can infect multiple hosts although its pathogenic potential in wild ruminants has been poorly studied. The polymerase chain reaction and the serological test detected the presence of C. burnetii in a population of North African gazelles (n = 355), comprising dorcas gazelle (Gazella dorcas neglecta), dama gazelle (Nanger dama mhorr) and Cuvier's gazelle (Gazella cuvieri) which, some of them, they recently aborted...

Macrophages are at the frontline of defense against pathogenic microorganisms. However, very little is known about the cell invasion mechanism of classical swine fever virus (CSFV) Shimen strain. To elucidate the infective mechanism of this important pathogen, we screened deep-sequencing data derived from macrophages infected with CSFV Shimen and uninfected macrophages, and identified a role of caveolin-1 (CAV1). Digital gene expression profiling showed that CAV1 was differentially expressed in CSFV Shimen-infected macrophages...

Rift Valley fever virus (RVFV), a Category A pathogen and select agent, is the causative agent of Rift Valley fever. To date, no fully licensed vaccine is available in the U.S. for human or animal use and effective antiviral drugs have not been identified. The RVFV MP12 strain is conditionally licensed for use for veterinary purposes in the U.S. which was excluded from the select agent rule of Health and Human Services and the U.S. Department of Agriculture. The MP12 vaccine strain is commonly used in BSL-2 laboratories that is generally not virulent in mice...

Malignant catarrhal fever (MCF) is a fatal disease of cattle that, in East Africa, follows contact with wildebeest excreting alcelaphine herpesvirus 1 (AlHV-1). Recently an attenuated vaccine (atAlHV-1) was tested under experimental challenge on Friesian-Holstein (FH) cattle and gave a vaccine efficacy (VE) of approximately 90%. However testing under field conditions on an East African breed, the shorthorn zebu cross (SZC), gave a VE of 56% suggesting that FH and SZC cattle may respond differently to the vaccine...
