Neutral protease activity was significantly elevated in the cerebro-spinal fluid of patients with multiple sclerosis (MS) in exacerbation and in the acute phase of acute viral meningoencephalitis (AME) compared with that of MS in remission, amyotrophic lateral sclerosis or psychosomatic disease.
Naegleria fowleri causes acute and fulminant primary amoebic meningoencephalitis. This microorganism invades its host by penetrating the olfactory mucosa and then traveling up the mesaxonal spaces and crossing the cribriform plate; finally, the trophozoites invade the olfactory bulbs. During its
Angiostrongylus cantonensis is a parasitic nematode dwelling in the heart and pulmonary arteries of rats, which can cause angiostrongyliasis in human by accidental infections, manifested as eosinophilic meningitis or meningoencephalitis. Cysteine proteases are the major class of endopeptidases that
The protozoon Naegleria fowleri (N. fowleri) is a free-living amoeba that produces primary amoebic meningoencephalitis (PAM), which is an acute and frequently fatal infection of the central nervous system. We characterized the strains of N. fowleri isolated from the cerebrospinal fluid (CSF) of two
Naegleria fowleri is a unicellular eukaryote causing primary amoebic meningoencephalitis, a neuropathic disease killing 99% of those infected, usually within 7-14 days. Naegleria fowleri is found globally in regions including the US and Australia. The genome of the related nonpathogenic species
Naegleria fowleri is the etiologic agent of primary amebic meningoencephalitis, a rare but rapidly fatal disease of humans. It invades the central nervous system via nasal mucosa and cribriform plate. Once in brain tissue, the organism induces an acute hemorrhagic, necrotizing meningoencephalitis.
Naegleria fowleri is the etiologic agent of primary amoebic meningoencephalitis (PAM). Proteases have been suggested to be involved in tissue invasion and destruction during infection. We analyzed and compared the complete protease profiles of total crude extract and conditioned medium of both
Naegleria fowleri causes a lethal primary amoebic meningoencephalitis (PAM) in humans and experimental animals, which leads to death within 7-14 days. Cysteine proteases of parasites play key roles in nutrient uptake, excystment/encystment, host tissue invasion, and immune evasion. In this study, we
Primary amebic meningoencephalitis (PAM) is a rapidly fatal infection caused by the free-living ameba Naegleria fowleri. PAM occurs principally in healthy children of less than 13 years old with a history of recent exposure to warm fresh water. While as yet not a reportable disease, the Centers for
Naegleria fowleri is a free-living amoeba that causes an opportunistic fatal infection known as primary amoebic meningoencephalitis (PAM) in humans. Cysteine proteases produced by the amoeba may play critical roles in the pathogenesis of infection. In this study, a novel cysteine Highly active antiretroviral therapy (HAART), that includes human immunodeficiency virus (HIV) protease inhibitors (PIs), has been remarkably efficacious including against some opportunistic infections. In this report we investigated the effect(s) of the PI indinavir on protease activity by
Chagas' disease, caused by the parasite Trypanosoma cruzi, remains the leading cause of cardiopathy in Latin America with about 12 million people infected. Classic clinical manifestations derive from infection of muscle cells leading to progressive cardiomyopathy, while some patients develop
The aim of this study was to examine three serial isolates of Cryptococcus neoformans from a patient with AIDS for genotypical and phenotypical characteristics. The isolates were obtained during a first episode of cryptococcosis (simultaneous sampling of blood and cerebrospinal fluid) and after a
Neonatal meningitis is a rare but devastating condition. Multi-drug resistant (MDR) bacteria represent a substantial global health risk. This study reports on an aggressive case of lethal neonatal meningitis due to a MDR Escherichia coli (serotype O75:H5:K1). Serotyping, MDR pattern and phylogenetic
The Cathepsin-D proteinase was demonstrated immunohistochemically in cases of intestinal coccidiosis in chickens; its expression concerned almost the cyto-invasive stages of reproductive cycle of several strains of coccidia (merozoites of the II-nd generation and also microgametes). The authors
