BACKGROUND: Mycobacterium tuberculosis (TB) is a common pathogen worldwide, and it may cause significant infection after solid organ transplantation (SOT). We reviewed all reported TB cases to provide an update on its epidemiology, clinical presentation, management and outcome after SOT. METHODS: MEDLINE, EMBASE, and OVID were reviewed from January 1, 1998 to Dec 31, 2016 using key words tuberculosis and solid organ transplant or transplantation. RESULTS: There were 187 publications reporting 2082 cases of TB among kidney (n=1719), liver (n=253), heart (n=77), lung (n=25), and kidney-pancreas (n=8) recipients...

We describe a case of Streptococcus gallolyticus subsp pasteurianus meningitis, unusually occurring in a splenectomised patient and complicated by cerebral venous thrombosis. Following presentation with meningism and diagnosis and management of S. gallolyticus meningitis, the patient represented with a further four days of fevers and subsequently developed left sided paresthesias. Cerebral imaging revealed venous thrombus in the right frontal cortical veins and left sigmoid sinus. The patient recovered following four weeks of intravenous ceftriaxone and anticoagulation with enoxaparin and then warfarin...

AIMS: Clinical guidelines for management of infants with fever but no evident focus of infection recommend that those aged 1-3 months with a white cell count >15 × 109 /l have a full septic screen and be admitted for parenteral antibiotics. However, there is limited information about leucocyte changes following routine immunization, a common cause of fever. We investigated white cell counts shortly after routine immunization in Ugandan infants under 3 months of age. METHODS: White cell counts were measured in 212 healthy infants following routine immunizations (DTwP-HepB-Hib, oral polio and pneumococcal conjugate 7 vaccines) received prior to 3 months of age...

Classical swine fever virus (CSFV) infection causes mild to severe diseases among pigs, depending on the age and immune status of the host and viral strains. CSFV targets various cells, including macrophages and conventional and plasmacytoid dendritic cells. Classical swine fever is one of the most devastating diseases of pigs which leads to high morbidity and mortality, and causes significant economic loss worldwide. In response to infection with CSFV, host innate immune system eliminates the virus by recognizing specific viral molecules via distinct cellular pattern recognition receptors...

Anaplasma phagocytophilum is the causative agent of human granulocytic anaplasmosis and tick-borne fever in domestic ruminants. Differential diagnosis of zoonotic and pathogenic tick-borne diseases like granulocytic anaplasmosis is important for the efficient implementation of control programs. Thus, the differentiation of pathogenic A. phagocytophilum from non-pathogenic A. phagocytophilum-like (APL) Anaplasma spp. is essential. Recent molecular analyses of APL revealed its distinct phylogenetic position from A...

Febrile neutropenia is a life-threatening condition that requires immediate attention, especially in patients with chemotherapy-related neutropenia. Patients with febrile neutropenia have a much greater risk of developing bacterial disease, and fever may be the only indicator of severe bacterial infection. Adequate management of febrile neutropenia emphasizes early recognition of patients, risk stratification, and antibiotic therapy administration during the first 60 minutes of admission to an emergency room...

Viruses must parasitize host cell translational machinery in order to make proteins for viral progeny. In this study, we sought to use this signal transduction conduit against them by inhibiting multiple kinases that influence translation. Previous work indicated that several kinases involved in translation, including p70 S6K, p90RSK, ERK, and p38 MAPK, are phosphorylated following Rift Valley fever virus (RVFV) infection. Furthermore, inhibiting p70 S6K through treatment with the FDA approved drug rapamycin prevents RVFV pathogenesis in a mouse model of infection...

The open reading frame of the nucleocapsid protein (NP) of Rift Valley fever virus (RVFV) strain MP12 was cloned and expressed in Vero E6 cells. The recombinant NP (rNP)-expressing cells were used as antigens for an indirect immunofluorescent antibody assay (IFA). The rNP-based IFA and RVFV-infected Vero E6 cell (authentic antigen)-based IFA showed similar IFA profiles with immune rabbit serum, which was prepared by immunization with rNP expressed using a baculovirus vector. A total of 942 traditional cattle sera obtained in five districts in Central, Southern, and Western provinces of Zambia were screened for anti-RVFV antibodies by the authentic antigen-based and rNP-based IFAs...

Lassa fever, a hemorrhagic fever caused by Lassa virus (LASV), is endemic in West Africa. It is difficult to distinguish febrile illnesses that are common in West Africa from Lassa fever based solely on a patient's clinical presentation. The field performance of recombinant antigen-based Lassa fever immunoassays was compared to that of quantitative polymerase chain assays (qPCRs) using samples from subjects meeting the case definition of Lassa fever presenting to Kenema Government Hospital in Sierra Leone. The recombinant Lassa virus (ReLASV) enzyme-linked immunosorbant assay (ELISA) for detection of viral antigen in blood performed with 95% sensitivity and 97% specificity using a diagnostic standard that combined results of the immunoassays and qPCR...

On September 2, 2017, the U.S. Food and Drug Administration approved gemtuzumab ozogamicin (GO; Mylotarg; Pfizer, New York City, NY) for treatment of relapsed or refractory (R/R) CD33-positive acute myeloid leukemia (AML) in patients 2 years of age and older. GO is a CD33-directed antibody drug conjugate linked to the cytotoxic antibiotic calicheamicin. It originally received accelerated approval for treatment of older patients with relapsed CD33-positive AML in 2000, but it was withdrawn from the market in 2010 when the confirmatory trial failed to demonstrate clinical benefit among safety concerns, such as a higher rate of induction fatalities on the GO combination arm compared with chemotherapy alone...

BACKGROUND: Various tick-borne infections often occur without specific clinical signs and are therefore notoriously hard to diagnose separately in veterinary practice. Longitudinal studies over multiple tick seasons performing clinical, serological and molecular investigations in parallel, may elucidate the relationship between infection and disease. In this regard, six related Rhodesian Ridgeback dogs living as a pack became subject of lifetime studies due to ongoing tick infestations and recurring clinical problems...

INTRODUCTION: Urinary tract infections (UTI) in patients with neurogenic lower urinary tract dysfunction (NLUTD) are defined as complicated UTI requiring antibiotic treatment. As the emergence of multiresistant strains is a serious problem, we assessed the feasibility of nonantibiotic treatment of UTI in patients with NLUTD. MATERIALS AND METHODS: In a prospective study evaluating the usefulness of UTI prophylaxis, participants could opt for either antibiotic or nonantibiotic treatment of breakthrough UTI...

Rat bite fever due to Streptobacillus moniliformis induces typical but not pathognomonic clinical signs, such as local purulent wound infection followed by maculopapular exanthema, myalgia as well as purulent joint infections. Severe complications, such as osteomyelitis and endocarditis are possible. it seems that this infection is rarely diagnosed but this infection could be much more common because the final diagnostic proof is difficult to achieve. Firstly, the culture of these bacteria is critical because the bacteria are fastidious and secondly the exact differentiation of the isolates is hardly possible by standard laboratory methods...

We present a 64-year-old woman with autosomal dominant polycystic kidney disease and hepatic cysts admitted to our hospital for high fever, intense coughing and right abdominal pain. The chest X-ray showed right pleural effusion suggestive of pneumonia. An abdominal ultrasound and computed tomography (CT) were done but did not show evidence of cyst infection or other abdominal complications. A gallium-67-citrate single-photon emission CT/CT, a relatively cheaper technique than positron emission tomography/CT was performed...

Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease caused by a tick-borne phlebovirus of the family Bunyaviridae , the SFTS virus (SFTSV). Wild type and type I interferon (IFN-I) receptor 1-deficient (IFNAR1-/- ) mice have been established as non-lethal and lethal models of SFTSV infection, respectively. However, the mechanisms of IFN-I production in vivo and the factors causing the lethal disease are not well understood. Using bone marrow chimeric mice, we found that IFN-I signaling in hematopoietic cells was essential for survival from lethal SFTSV infection...

Yellow fever (YF) is a reemerging public health threat with frequent outbreaks prompting large vaccination campaigns in endemic regions of Africa and South America. Specific detection of vaccine-related adverse events is resource-intensive, time-consuming and difficult to achieve during an outbreak. To address this, we have developed a highly transferable, rapid yellow fever virus (YFV) vaccine-specific real-time RT-PCR assay that distinguishes vaccine from wild-type lineages. The assay utilizes a specific hydrolysis probe that includes locked nucleic acids to enhance specific discrimination of the YFV 17D vaccine strain genome...
