Sporotrichosis is a human and animal disease caused by species of the Sporothrix schenckii complex. It is classically acquired through traumatic inoculation of fungal elements. Most frequently, sporotrichosis presents as a fixed cutaneous or as a lymphocutaneous form. A much smaller number of cases occur as cutaneous disseminated and disseminated forms. These cases require immediate diagnosis and management to reduce morbidity and mortality. We present the case of a 34-year-old male patient in whom the first presentation of HIV infection was a rapidly progressive sporotrichosis with multiple cutaneous lesions, a high fungal burden in tissues, and pulmonary involvement...

In 2014, a new bluetongue virus serotype 4 (BTV-4) strain was detected in southern Greece and spread rapidly throughout the Balkan Peninsula and adjacent countries. Within half a year, more than 7,068 outbreaks were reported in ruminants, particularly in sheep. However, the reported morbidity and case fatality rates in ruminants varied. The pathogenesis of a Bulgarian BTV-4 strain isolated from sheep during the BTV-4 epizootic was studied in different species. Therefore, four sheep, three goats and three cattle were experimentally infected with the isolate BTV-4/BUL2014/15 and monitored for clinical signs up to several weeks...

Background Implementation of an ivermectin-based community treatment strategy for the elimination of onchocerciasis or lymphatic filariasis has been delayed in Central Africa because of the occurrence of serious adverse events, including death, in persons with high levels of circulating Loa loa microfilariae. The LoaScope, a field-friendly diagnostic tool to quantify L. loa microfilariae in peripheral blood, enables rapid, point-of-care identification of persons at risk for serious adverse events. Methods A test-and-not-treat strategy was used in the approach to ivermectin treatment in the Okola health district in Cameroon, where the distribution of ivermectin was halted in 1999 after the occurrence of fatal events related to L...

Hepatocellular carcinoma (HCC) is one of the most common and rapidly fatal malignancies, for which hepatitis B virus (HBV) chronic infection constitutes a major risk factor. The lysosome-associated protein transmembrane-4 β gene (LAPTM4B) is a recently identified gene that was found to be overexpressed in several types of cancer. However, the role of LAPTM4B in HCC tumorigenesis and progression has not been clearly determined. The present study demonstrated that the mRNA as well as the protein levels of LAPTM4B were significantly upregulated in HCC specimens...

Aims Severe fever with thrombocytopenia syndrome (SFTS) is an emerging tick-borne infectious disease. SFTS is epidemic in Asia, and its fatality rate is around 30% in Japan. The causative virus severe fever with thrombocytopenia syndrome virus (SFTSV) is a phlebovirus of the family Phenuiviridae (the order Bunyavirales). Although effective treatments are required, there are no antiviral agents currently approved for clinical use. Ribavirin and favipiravir were examined for their anti-SFTSV activity and found to be selective inhibitors of SFTSV replication in vitro...

Portable analytical devices are notably gaining relevance in the panorama of urgent testing. Such devices have the potential to play an important role as easy-to-handle tools in critical situations. Epidemic infectious disease agents (e.g., Ebola virus, Coronavirus, Zika virus) could be controlled more easily by testing travelers on-site at the country borders to prevent outbreaks from spreading. The increasing incidence of hospital-acquired infections caused by antibiotic resistant pathogens could be minimized by point-of-care microbial analysis as well as rapid screening tests of bacteria resistance...

BACKGROUND: HIV positive patients can suffer many complications due to infectious diseases. A severe reaction to some of the drugs involved in the treatment can overlap with the symptoms of infections, making diagnosis very difficult. We present the case of an HIV positive 28-year-old-man, , with secondary syphilis, who developed a Stevens Johnson Syndrome (SJS) caused by one of the many drugs he was receiving. The SJS overlapped with a possible Jarisch Herxheimer Reaction, which complicated diagnosis of the skin reaction...

Tuberculosis continues to be an important cause of morbidity and mortality worldwide. It is the leading cause of infection-related deaths worldwide. Children are amongst the high-risk groups for developing tuberculosis and often pose a challenge to the clinicians in making a definitive diagnosis. The newly released global tuberculosis report from World Health Organization reveals a 50% increase in fatality from tuberculosis in children. Significantly, diagnostic and treatment algorithms of tuberculosis for children differ from those of adults...

Psittacine beak and feather disease (PBFD) is characterised by degenerative feather, feather dystrophy, and beak deformity. Sometimes acute forms can lead to fatal cases in nestlings. The worldwide distribution of this disease affects numerous species of parrots with an average prevalence of 40%, including in Taiwan. The pathogen of PBFD is beak and feather disease virus (BFDV), which is a single-stranded circular DNA virus, circovirus. To date, hemagglutination and PCR assays have been routinely used to detect this virus...

Vibrio vulnificus causes fatal infections in humans, and antibiotics are commonly used in treatment regimens against V. vulnificus infection. However, the therapeutic effects of antibiotics are limited by multidrug resistance. In this study, we demonstrated that an antimicrobial peptide (AMP), HPA3P(His), loaded onto a gold nanoparticle-DNA aptamer (AuNP-Apt) conjugate (AuNP-Apt-HPA3P(His)) is an effective therapeutic tool against V. vulnificus infection in vivo in mice. HPA3P(His) induced bacterial cell death through the disruption of membrane integrity of V...

Ruptured pseudoaneurysm following pelvic surgery is a rare and fatal complication. Because of its rarity, existing evidence is limited to a small case series. A 60-year-old woman underwent staging laparotomy, including pelvic and para-aortic lymphadenectomy, for ovarian cancer. On the 11th day, the patient developed a sudden lumbar pain and loss of consciousness, which resulted in a state of shock. She was diagnosed as having a pelvic abscess and ruptured external iliac artery pseudoaneurysm. We performed ligation of the external iliac artery to restrain hemorrhage and femoro-femoral artery bypass to prevent infection, which saved the patient's life...

Rhinocerebral mucormycosis is an acute, rapidly fatal, fungal infection, classically involving the nasal mucosa and paranasal sinuses. It is an aggressive, opportunistic infection that frequently progresses to involve the orbit and cerebrum. Cerebral extension in immunocompromised patients is almost universally fatal. There are limited data on mucormycosis in pediatric immunocompromised patients in the literature, with only few reports on rhinocerebral involvement. The immunocompromised patients described in this report presented with suspected periorbital and nasal cellulitis, progressing rapidly to necrotic changes in nasal tissue and oral palatal mucosa...

Cancer care has become increasingly specialized and advances in therapy have resulted in a larger number of patients receiving care. There has been a significant increase in the number of patients presenting with cancer related emergencies including treatment toxicities and those directly related to the malignancy. Suspected neutropenic sepsis is an acute medical emergency and empirical antibiotic therapy should be administered immediately. The goal of empirical therapy is to cover the most likely pathogens that will cause life-threatening infections in neutropenic patients...

Invasive fungal infections are a serious cause of morbidity and mortality in patients with hematologic malignancies. Conidiobolus species are molds within the order Entomophthorales and may disseminate to become rapidly fatal in immunocompromised individuals. This species of fungal infections are often multidrug resistant (MDR) and present unique therapeutic challenges. Reports of Conidiobolus infections are rare in pediatric oncology. We report the successful treatment of an adolescent male with B-cell lymphoblastic leukemia and MDR invasive sinopulmonary Conidiobolus infection with emphasis on early and aggressive neutrophil support with surgical debridement...

BACKGROUND: Chagas disease is a debilitating often fatal disease resulting from infection by the protozoan parasite Trypanosoma cruzi. Chagas disease is endemic in 21 countries of the Americas, and it is an emerging disease in other countries as a result of migration. Given the chronic nature of the infection where intracellular parasites persist for years, the diagnosis of T. cruzi by direct detection is difficult, whereas serologic tests though sensitive may yield false-positive results...

James G Shepherd, Ann L N Chapman
More than 25% of the world population has been infected with tuberculosis (TB), however only 10% of those infected will ever develop active disease. Clinically significant disease occurs through progression of primary infection or through later reactivation of latent TB infection (LTBI); this is most likely to occur in the first few years following infection, although late reactivation can occur several decades later, particularly in individuals who become immunosuppressed. Risk of TB acquisition is increased in people who have come to the UK from high incidence countries or who are born in the UK but come from high-risk ethnic minority groups...

Cholera is an acute bacterial gastrointestinal infection caused by ingestion of water or food containing the pathogen Vibrio cholerae. The incubation period can be very short and it takes between several hours and 5 days. During the 19th century, cholera was spreading from India across the world. Its original reservoir was located in the Ganges delta. So far, there have been six epidemics of cholera; the current outbreak is the seventh. It started in Asia, attacked Africa and then the Americas. Cholera causes thousands of illnesses and deaths annually, mostly in South Asia and Sub-Saharan Africa...

Ebola virus (EBOV) disease (EVD) results from an exacerbated immunological response that is highlighted by a burst in the production of inflammatory mediators known as a "cytokine storm." Previous reports have suggested that nonspecific activation of T lymphocytes may play a central role in this phenomenon. T-cell immunoglobulin and mucin domain-containing protein 1 (Tim-1) has recently been shown to interact with virion-associated phosphatidylserine to promote infection. Here, we demonstrate the central role of Tim-1 in EBOV pathogenesis, as Tim-1(-/-) mice exhibited increased survival rates and reduced disease severity; surprisingly, only a limited decrease in viremia was detected...
