Background: Central nervous system fungal infections (FI) are important complications and a cause of mortality in patients who receive hematopoietic stem cell transplantation (HSCT).
Aims: To study the clinical aspects of fungal encephalitis (FE).
Settings And Design: The study was carried out at the HSCT Center of the Hospital de Clínicas, Federal University of Paraná, Curitiba, Brazil.
Materials And Methods: Clinical records and autopsy reports from patients submitted to HSCT with a diagnosis of FE.
Results: Twelve patients were diagnosed with FE presenting with lowered level of consciousness, hemiparesis and seizures. We were able to identify two subgroups regarding susceptibility to FE: (1) patients with early onset FI and severe leucopenia, and (2) patients with later onset FI with graft-versus-host disease using immunosuppressive drugs. Eleven of the patients died directly due to the neurological complication, all had post-mortem confirmation of the diagnosis of FI.
Conclusions: These clinical, paraclinical and temporal patterns may provide the opportunity for earlier diagnosis and interventions.

Background: Herpes simplex encephalitis (HSE), caused by herpes simplex virus (HSV) is the most common cause of sporadic encephalitis that often presents as an emergency case of acute or sub-acute nature associated with poor prognosis. Early suspicion and prompt diagnostic testing with adequate antiviral therapy can only reduce morbidity and mortality associated with the disease. This study aims to evaluate the role of serological and molecular diagnosis of encephalitis caused by HSV 1 and 2 for timely detection of the disease.

Japanese encephalitis virus (JEV) is a neurotropic zoonotic pathogen that poses a serious threat to public health. Currently, there is no specific therapeutic agent available for JEV infection, primarily due to the complexity of its infection mechanism and pathogenesis. Extracellular vesicles (EVs) have been known to play an important role in viral infection, but their specific functions in JEV infection remain unknown.

In RNA interference (RNAi), long double-stranded RNA is cleaved by the Dicer endonuclease into small interfering RNAs (siRNAs), which guide degradation of complementary RNAs. While RNAi mediates antiviral innate immunity in plants and many invertebrates, vertebrates have adopted a sequence-independent response and their Dicer produces siRNAs inefficiently because it is adapted to process small hairpin microRNA precursors in the gene-regulating microRNA pathway. Mammalian endogenous RNAi is thus a rudimentary pathway of unclear significance.

The tick-borne encephalitis virus is a pathogen endemic to northern Europe and Asia, transmitted through bites from infected ticks. It is a member of the family and possesses a positive-sense, single-stranded RNA genome encoding a polypeptide that is processed into seven non-structural and three structural proteins, including the envelope (E) protein. The glycosylation of the E protein, involving a single N-linked glycan at position N154, plays a critical role in viral infectivity and pathogenesis.

cuniculi infection in rabbits represents a true challenge in both diagnosis and treatment of the disease. This study aims to describe and analyze all methods of identifying the presence of the microsporidian in a rabbit through antemortem and postmortem methods. The patient manifested clinical signs of vestibular disease and mild renal symptoms with no significant improvement under treatment, which finally led to euthanasia.
