African swine fever (ASF) is a highly contagious haemorrhagic disease of pigs that has the potential to cause mortality nearing 100% in naïve animals. While an outbreak of ASF in the United States' pig population (domestic and feral) has never been reported, an introduction of the disease has the potential to cause devastation to the pork industry and food security. During the recovery phase of an outbreak, an antibody detection diagnostic assay would be required to prove freedom of disease within the previously infected zone and eventually nationwide...

Rift Valley fever virus (RVFV) is considered an enzootic virus in Africa. RVFV has caused several outbreaks in Egypt, sub-Saharan Africa and the Arabian Peninsula and is responsible for high mortality in ruminants and haemorrhagic fever in severe human cases. Although there are several molecular and serological diagnostic techniques used to detect this arthropod-borne virus with high sensitivity and efficiency, there is a need for a fast and reliable field screening test for rapid outbreak recording and containment...

Ebola haemorrhagic fever causes deadly disease in humans and non-human primates resulting from infection with the Ebola virus (EBOV) genus of the family Filoviridae. However, the mechanisms of EBOV lifecycle in host cells, including viral entry, membrane fusion, RNP formation, GP-tetherin interaction, and VP40-inner leaflet association remain poorly understood. This review describes the biological functions of EBOV proteins and their roles in the lifecycle, summarizes the factors related to EBOV proteins or RNA expression throughout the different phases, and reviews advances with regards to the molecular events and mechanisms of the EBOV lifecycle...

BACKGROUND: The apoptosis of microvascular endothelial cells causes plasma leakage in dengue haemorrhagic fever patients. The soluble Fas ligand is a protein with molecular weight of 40 kDa that acts as a mediator of apoptosis. This study aimed to prove whether soluble Fas ligand can be used as a potential marker to predict the severity of dengue infection by comparing the soluble Fas ligand levels in dengue fever (DF) and dengue haemorrhagic fever (DHF) patients early in the course of illness...

Acute myeloid leukaemia (AML) often presents with non-specific symptoms such as fatigue, anaemia or infection. Pulmonary involvement is uncommon in AML during the course of the disease and is usually caused by infection, haemorrhage, leukaemic pulmonary infiltrates and leukostasis. Lung localization of AML is very uncommon and potentially life threatening if not diagnosed and treated rapidly. The authors describe the sudden death of an asymptomatic five-month-infant because of a misdiagnosed lung localization of AML...

Vector borne diseases remain the major source of illness and death worldwide. Aedes aegypti is the primary carrier of dengue and dengue haemorrhagic fever in many developing countries in the tropical world. Because A. aegypti populations are becoming more and more resistant to conventional and non conventional insecticides, alternative strategies have to be rapidly implemented in the future for dengue vector control. The present study aimed to evaluate the larvicidal efficacy of slow-release formulations (SRFs) of bacterial insecticide Bactimos briquets blended with tow insect growth regulators (IGRs), Altosid XR - briquets and Dudim DT tablet respectively, against mosquito larvae of A...

African swine fever virus (ASFV) is a large DNA virus that replicates predominantly in the cell cytoplasm and is the only member of the Asfarviridae family. The virus causes an acute haemorrhagic fever, African swine fever (ASF), in domestic pigs and wild boar resulting in the death of most infected animals. Apoptosis is induced at an early stage during virus entry or uncoating. However, ASFV encodes anti-apoptotic proteins which facilitate production of progeny virions. These anti-apoptotic proteins include A179L, a Bcl-2 family member; A224L, an inhibitor of apoptosis proteins (IAP) family member; EP153R a C-type lectin; and DP71L...

A 26-year-old woman presented with a 5-day history of fever and 3-day history of left upper quadrant abdominal pain and cough associated with left shoulder tip pain. Initial blood cultures did not display growth. On CT imaging, there was a cyst measuring 7.2×8 cm originally interpreted to be haemorrhagic in nature. Repeat cultures during admission revealed Salmonella Thompson. Percutaneous drainage and antibiotic treatment, rather than splenectomy, was successfully pursued with the patient afebrile and in no pain at 6 weeks follow-up...

Fever is a common symptom in the Intensive Care Unit. At least half of febrile episodes are caused by infection. Excluding infectious etiology and other non-infectious causes of fever, especially in patients with central nervous system (CNS) disorders, attention should be paid to disturbances of thermoregulatory centre. In particular, subarachnoid haemorrhage, cerebral trauma, along with ischaemic or haemorrhagic stroke are strongly associated with the development of central fever. Proper, speedy diagnosis of the cause of fever makes it possible to implement preventive measures against the harmful effects of hyperthermia on the CNS and to avoid the consequences of inappropriate treatment...

BACKGROUND: Recently moderate-virulence classical swine fever virus (CSFV) strains have been proven capable of generating postnatal persistent infection (PI), defined by the maintenance of viremia and the inability to generate CSFV-specific immune responses in animals. These animals also showed a type I interferon blockade in the absence of clinical signs. In this study, we assessed the infection generated in 7-week-old CSFV PI wild boars after infection with the African swine fever virus (ASFV)...

Wunderlich Syndrome (WS) is an uncommon condition where acute onset of spontaneous bleeding occurs into the subcapsular and perirenal spaces. It can prove fatal if not recognized and treated aggressively at the appropriate time. A 32-year-old male diagnosed elsewhere as acute renal failure presented with tender left loin mass, fever and hypovolemic shock with serum creatinine 8.4 mg/dl. He was started on higher antibiotics and initiated on haemodialysis. Ultrasonogram (USG), Non-Contrast Computed Tomography (NCCT) and Magnetic Resonance Imaging (MRI) showed bilateral perirenal subcapsular haematomas - right 3...

BACKGROUND: Puumala hantavirus (PUUV) causes haemorrhagic fever with renal syndrome characterized by thrombocytopenia, capillary leakage and acute kidney injury (AKI) with proteinuria and haematuria. Although the typical histologic lesion is acute tubulointerstitial nephritis, the amount of glomerular proteinuria predicts the severity of upcoming AKI. Here, we studied the associations of haematuria and proteinuria with the severity of emerging AKI, thrombocytopenia and markers of coagulation and fibrinolysis in PUUV infection...
