A species of free-living soil amoeba in the family Balamuthiidae, causing AMEBIASIS and a deadly form of ENCEPHALITIS in humans.
Infection with any of various amebae. It is an asymptomatic carrier state in most individuals, but diseases ranging from chronic, mild diarrhea to fulminant dysentery may occur.
A class of amoeboid EUKARYOTES that forms either filiform subpseudopodia or lobopodia. Characteristics include the absence of sorocarps, sporangia, or similar fruiting bodies. Lobosea were formerly members of the phylum Sarcomastigophora, subphylum Sarcodina, under the old five kingdom paradigm.
A supergroup (some say phylum) of ameboid EUKARYOTES, comprising ARCHAMOEBAE; LOBOSEA; and MYCETOZOA.
Infections of the brain, spinal cord, or meninges by single celled organisms of the former subkingdom known as protozoa. The central nervous system may be the primary or secondary site of protozoal infection. These diseases may occur as OPPORTUNISTIC INFECTIONS or arise in immunocompetent hosts.
A genus of ameboid protozoa. Characteristics include a vesicular nucleus and the formation of several lodopodia, one of which is dominant at a given time. Reproduction occurs asexually by binary fission.
Inflammation of the BRAIN due to infection, autoimmune processes, toxins, and other conditions. Viral infections (see ENCEPHALITIS, VIRAL) are a relatively frequent cause of this condition.
An inflammatory process involving the brain (ENCEPHALITIS) and meninges (MENINGITIS), most often produced by pathogenic organisms which invade the central nervous system, and occasionally by toxins, autoimmune disorders, and other conditions.
A species of parasitic protozoa having both an ameboid and flagellate stage in its life cycle. Infection with this pathogen produces PRIMARY AMEBIC MENINGOENCEPHALITIS.
Agents which are destructive to amebae, especially the parasitic species causing AMEBIASIS in man and animal.
Infections with unicellular organisms formerly members of the subkingdom Protozoa.
Cells or feeding stage in the life cycle of sporozoan protozoa. In the malarial parasite, the trophozoite develops from the MEROZOITE and then splits into the SCHIZONT. Trophozoites that are left over from cell division can go on to form gametocytes.
A genus of free-living soil amoebae that produces no flagellate stage. Its organisms are pathogens for several infections in humans and have been found in the eye, bone, brain, and respiratory tract.
Death resulting from the presence of a disease in an individual, as shown by a single case report or a limited number of patients. This should be differentiated from DEATH, the physiological cessation of life and from MORTALITY, an epidemiological or statistical concept.
The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.

Granulomatous amoebic encephalitis caused by Balamuthia mandrillaris. (1/5)

A 51-year-old immunocompetent Japanese woman presented with a rare case of granulomatous amoebic encephalitis (GAE) caused by Balamuthia mandrillaris. She was brought to our hospital with epilepsy. Magnetic resonance imaging of the brain revealed a homogeneously enhanced solitary mass in the left frontal lobe. Histological diagnosis was made by a biopsy, which suggested lymphomatoid granulomatosis. After that, her neurological condition got worse. New masses were found and had spread across the whole brain. She died 2 months later of cerebral hernia. Autopsy revealed that the patient had GAE caused by Balamuthia mandrillaris. GAE is usually fatal, and is difficult to diagnose except at autopsy. Therefore, awareness of this disease is important, and earlier diagnosis and the development of a better therapeutic strategy will improve clinical outcome.  (+info)

Infections caused by free-living amebae (FLA) are severe and life-threatening. These infections include primary amebic meningoencephalitis (PAM) caused by Naegleria fowleri and granulomatous amebic encephalitis caused by Balamuthia mandrillaris and Acanthamoeba species. Although several drugs have in vitro activity against FLA, mortality from these infections remains>90% despite treatment with combinations of drugs.  (+info)

Successful treatment of granulomatous amoebic encephalitis with combination antimicrobial therapy. (5/5)

Granulomatous amoebic encephalitis (GAE) is a rare but fatal infection. Due to its nonspecific symptoms and laboratory and neuroradiological findings, it is rarely diagnosed antemortem. We herein present the case of a 72-year-old Japanese woman who was diagnosed with GAE following the detection of a pathogen similar to Balamuthia mandrillaris under a microscopic examination of cerebrospinal fluid sediment and who achieved remission with combination antimicrobial therapy. There are no previous reports of pathogens similar to B. mandrillaris being detected in cerebrospinal fluid antemortem; therefore, this case may be used as a benchmark for further studies.  (+info)

Authors: MURAT CENGİZ, GÜLÇE HEPBOSTANCI Abstract: In this study, combination antimicrobial therapy, due to its higher potential against resistant bacteria, was evaluated for the inhibition of multidrug-resistant E. coli strains. The influence of pH as an environmental variable on the activity of antimicrobial combinations was evaluated by calculating the factional concentration indexes at pH values 5.0, 6.0, 7.3, and 8.0. The highest synergistic activity rates of ceftriaxone + colistin, danofloxacin + colistin, danofloxacin + ceftiofur, and ceftiofur + gentamicin combinations were 50%, 33%, 100%, and 50%, respectively measured at ≥7.3 pH. The lowest synergistic activity rates for all combinations were observed at the acidic pH values of 5.0 and 6.0. The results of this study clearly demonstrated that acidic pH of the medium impaired the activity of the antimicrobial combinations. Although ceftriaxone and ceftiofur exert optimal activity at acidic pH values, the synergistic activity of the ...

Case histories are presented of 2 individuals (a 5-year-old girl and 64-year-old man) who developed encephalitis caused by the free-living amoeba Balamuthia mandrillaris Both individuals survived after diagnosis and initiation of effective antimicrobial therapy. Immunostaining for Balamuthia-specific antibody levels identified the causative agent of the infections. Antimicrobial therapy with flucytosine, pentamidine, fluconazole, sulfadiazine, and a macrolide antibiotic (azithromycin or clarithromycin) was initiated. Phenothiazines (thioridazine and trifluoperazine) were also used. Both patients recovered, and there was no evidence of recrudescence of the disease at 2 and 6 years after onset of symptoms. Awareness of Balamuthia as the causative agent of encephalitis and early initiation of antimicrobial therapy were critical to the recovery of both patients. Although optimal antimicrobial therapy for Balamuthia amoebic encephalitis has yet to be determined, the antimicrobials used in these 2 ...
DESCRIPTION (provided by applicant): Helicobacter pylori (Hp), a gastric bacterial pathogen of humans; infection is the cause of type B gastritis and is also strongly associated with gastric carcinoma (intestinal type) and gastric MALT lymphoma. Combination antimicrobial therapy (triple therapy with a bismuth salt, metranidazole and a broad spectrum antibiotic) is successful in 80% of Hp-infected symptomatic patients; treatment failures are expressed as recrudescence of infection and clinical signs and are associated with development of antibiotic-resistant microbes and poor patient compliance. In a previous SBIR, we have demonstrated that parenteral immunization with an Hp proteolytic digest prevents colonization in Hp-challenged gnotobiotic swine. Preliminary data suggest that activated T cells and their products, in particular, interferon gamma (IFNg), are central for this immunoprotective effect. An ideal approach to the problem of recrudescence treatment failure is to combine antimicrobial ...

The genus Sappinia with the single species Sappinia pedata was established for an amoeba with two nuclei and pedicellate cysts by Dangeard in 1896. In 1912, Alexeieff transferred an also double nucleated, but apparently sexually reproducing amoeba to this genus as Sappinia diploidea that had been described as Amoeba diploidea by Hartmann and Nägler in 1908. Molecular analyses have confirmed the differentiation between S. pedata and S. diploidea; however, the genus splits into more than two well separated clusters. The genus Sappinia is now classified as a member of the Thecamoebidae and, moreover, as potentially pathogenic. Subacute or chronic CNS infections due to Acanthamoeba spp, Balamuthia mandrillaris, and Sappinia spp., which occasionally cause cerebral abscess, are termed granulomatous amebic encephalitis (GAE). In 2001, Gelman and colleagues reported a case of severe encephalitis in an immunocompetent young man caused by Sappinia. Another case of GAE and abscess formation was reported ...

Amoebic encephalitis is an infection of the brain caused by various different amoebae, for example Naegleria fowleri, Acanthamoeba species, Balamuthia mandrillaris, or Entamoeba histolytica.[5] These infections are rare, and usually lethal.[10] Naegleria fowleri causes primary amoebic encephalitis (PAE), which progresses very rapidly, whereas Acanthamoeba species cause granulomatous amoebic encephalitis (GAE), which is also usually lethal, but develops slower than PAE.[10] Acanthamoeba species and Balamuthia mandrillaris usually only cause disease in immunocompromised patients and Entamoeba histolytica can cause encephalitis after infecting another region in the body.[10] There has been only one documented case of pathogenesis involving Sappinia species, which resulted in granulomatous amoebic encephalitis in a non-immunocompromised 38-year-old male from Texas in 1998.[5] The fact that the patient was non-immunocompromised is surprising because there is only one known amoeba (Naegleria fowleri) ...

It is well-documented that early HIV diagnosis and linkage to care reduces morbidity and mortality as well as HIV transmission. We estimated the median time from HIV infection to diagnosis in the European Union/European Economic Area (EU/EEA) at 2.9 years in 2016, with regional variation. Despite evidence of a decline in the number of people living with undiagnosed HIV in the EU/EEA, many remain undiagnosed, including 33% with more advanced HIV infection (CD4 < 350 cells/mm3).
Abstract: The free-living amoebae of the genus Acanthamoeba are widely distributed in nature and are considered potentially pathogenic organisms. Occasionally they can trigger human infections such as granulomatous amoebic encephalitis and amoebic keratitis. The investigation of differentiating characteristics between pathogenic strains and those not associated with infection may help to determine factors related to pathogenicity and the development of diagnostic tests. In this sense, the aim of this study was to perform a comparative evaluation; by means of physiological, morphological and immunochemical criteria; between clinical and environmental samples of Acanthamoeba. Trophozoites of four isolates were used: a clinical sample, obtained from a confirmed case of amoebic keratitis; an environmental sample, obtained from the dust of the residence of the same patient; and two reference samples A. poliphaga #2, obtained from an amoebic keratitis (ATCC 30641) and A. poliphaga #4, obtained from ...
This study has investigated the relationship between clinical parameters and functional status for activities of daily living (ADL) in 364 people living with HIV/AIDS (PLWHA) in Belém, northern Brazil. In total, 238 men (65.4%) and 126 women (34.6%) were enrolled in this survey. Most participants (87.4%) were considered with functional independence, 11.8% were semi-dependent and 0.8% were fully dependent. Tuberculosis, neurotoxoplasmosis and syphilis were the most common HIV-associated comorbidities and cumulative comorbidities were linked to lower independence. Low CD4+ count and long duration of HIV infection were both related to decreased independence. Women were more affected by low mood/demotivation than men, the last had higher employment rates and more access to higher education, which may have contributed to a better emotional status. We concluded that duration of HIV infection, low CD4+ count and history of HIV-associated comorbidities affects functional status and compromise the independence

Free-living amebas, usually harmless protozoan residents of soil and water, can cause three distinct, occasionally devastating, human illnesses. Primary amebic meningoencephalitis (PAM) is a disease of the previously healthy and is caused by Naegleria fowleri. Granulomatous amebic encephalitis (GAE) is caused by Acanthamoeba species or Balamuthia mandrillaris, and occurs in both healthy and immunocompromised persons. In wealthier countries, contact lens users may suffer from chronic amebic keratitis, also caused by Acanthamoeba. While these diseases are found worldwide, they are more common in tropical and subtropical regions. ...

Free-living amoebae (or FLA) in the Amoebozoa group are important causes of disease in humans and animals. Naegleria fowleri is sometimes included in the group free-living amoebae, and it causes a condition traditionally called primary amoebic meningoencephalitis. However, Naegleria is now considered part of the Excavata, not the Amoebozoa, and is considered to be much more closely related to Leishmania and Trypanosoma. Acanthamoeba spp. and Balamuthia mandrillaris are opportunistic free-living amoebae capable of causing granulomatous amoebic encephalitis (GAE) in individuals with compromised immune systems. Acanthamoeba spp. have been found in soil; fresh, brackish, and sea water; sewage; swimming pools; contact lens equipment; medicinal pools; dental treatment units; dialysis machines; heating, ventilating, and air conditioning systems; mammalian cell cultures; vegetables; human nostrils and throats; and human and animal brain, skin, and lung tissues.
