In vivo tandem scanning confocal microscopy in acanthamoeba keratitis. (1/141)

The in vivo confocal microscopy technique provides us with a real-time, non-invasive way of examining the human cornea. The most important advantage of this type of microscopy is to reveal the etiologic agents in infectious keratitis such as Acanthamoeba keratitis. We present several representative cases of Acanthamoeba keratitis, which were diagnosed in their early stages using in vivo confocal microscopy and managed based on that diagnosis. In our Acanthamoeba keratitis cases, highly-reflective round or ovoid organisms with a diameter of about 10-25 um were visualized distinctly against relatively-dark normal parenchymal structures, such as epithelial cells or keratocyte nuclei. Double-walled structures of Acanthamoeba cysts were clearly demonstrated in some cases. We can confirm that in vivo tandem scanning confocal microscopy is a powerful diagnostic tool for identifying the infecting organisms in Acanthamoeba keratitis.  (+info)

Corneal ulceration in the elderly in Hyderabad, south India. (2/141)

AIMS: To report demographic, microbiological, therapeutic, anatomical, and visual results of corneal ulceration in the elderly patients seen at a tertiary eye care centre in south India. METHODS: 102 consecutive cases of microbial keratitis in patients 65 years and older were studied. Inclusion criteria were: (i) presence of corneal stromal infiltrate upon slit lamp examination; and (ii) microbiological evaluation of corneal scrapings for suspected microbial keratitis. RESULTS: The principal predisposing factors identified in this study were ocular disease (38.2%), previous ocular surgery in the same eye (29.4%), trauma (17.6%), and severe systemic disease (16.7%). Contact lens wear was associated with only two cases (2.0%). 99 organisms were isolated in cultures of corneal scrapings from 74 (72.5%) of the 102 cases. Staphylococcus epidermidis (31.1%), filamentous fungi (25.7%), and Streptococcus pneumoniae (13.5%) were the most common isolates. 12 eyes (11.8%) required surgery, 15 (14.7%) eventually required evisceration, and nine (9.6%) of the 94 followed patients achieved an unaided vision of 20/60 or better at last follow up. CONCLUSIONS: This work represents the largest recent single centre study on (non-viral) microbial keratitis in the elderly, its management, and outcomes of therapy. While the predisposing factors differ from those of general population, the spectrum of microbes responsible for keratitis in the elderly appears to reflect the local microbial flora rather than a predilection for elderly patients. Delay in diagnosis and systemic conditions associated with advancing age probably contribute to poorer outcome from therapeutic measures.  (+info)

Random amplified polymorphic DNA profiles as a tool for the characterization of Brazilian keratitis isolates of the genus Acanthamoeba. (3/141)

The genus Acanthamoeba comprises free-living amebae identified as opportunistic pathogens of humans and other animal species. Morphological, biochemical and molecular approaches have shown wide genetic diversity within the genus. In an attempt to determine the genetic relatedness among isolates of Acanthamoeba we analyzed randomly amplified polymorphic DNA (RAPD) profiles of 11 Brazilian isolates from cases of human keratitis and 8 American type culture collection (ATCC) reference strains. We found that ATCC strains belonging to the same species present polymorphic RAPD profiles whereas strains of different species show very similar profiles. Although most Brazilian isolates could not be assigned with certainty to any of the reference species, they could be clustered according to pattern similarities. The results show that RAPD analysis is a useful tool for the rapid characterization of new isolates and the assessment of genetic relatedness of Acanthamoeba spp. A comparison between RAPD analyses and morphological characteristics of cyst stages is also discussed.  (+info)

Isoenzyme patterns and phylogenetic relationships in Acanthamoeba spp. isolated from contact lens containers in Korea. (4/141)

In order to refer to the basic information regarding the identification of isolates obtained from a contact lens container in Korea, the isoelectric focusing gel electrophoresis was employed to compare the isoenzyme band patterns among Acanthamoeba spp. including eight isolates and the simple pairwise dissimilarity analysis was carried out. For an alkaline phosphate development, isolate 7 and Acanthamoeba polyphaga showed homologous band patterns, and isolates 1, 2, and 3 showed the same patterns. For lactate dehydrogenase, similar patterns were observed in isolates 2 and 3. Isolates 3 and 5 showed homologous band patterns for malate dehydrogenase and glucose phosphate isomerase. For hexokinase, isolates 4, 7, and A, hatchetti showed the same band patterns. In others, a considerable number of interstrain polymorphisms was observed in nine isoenzyme band patterns. In Acanthamoeba group II, genetic distances among isolates 1, 2, 3, 4, and 5 ranged from 0.104 to 0.200. In comparison to A. castellanii, A. hatchetti, and A. polyphaga, genetic distances of isolates 7 and 8 were 0.254 and 0.219, respectively. In Acanthamoeba group III, including A. culbertsoni, A. healyi, and A. royreba, isolate 6 had genetic distances which ranged from 0.314 to 0.336. Finally, when comparing to the six reference Acanthamoeba, it was possible to classify isolates 1, 2, 3, 4, and 5, as genetically close-related species and as independent species group. Furthermore, isolates 6, 7 and 8 were identified as independent species as well.  (+info)

Unusual case of Acanthamoeba polyphaga and Pseudomonas aeruginosa keratitis in a contact lens wearer from Gauteng, South Africa. (5/141)

Acanthamoeba species can cause a chronic, progressive ulcerative keratitis of the eye which is not responsive to the usual antimicrobial therapy and is frequently mistaken for stromal herpes keratitis. An unusual case of coinfection with Acanthamoeba polyphaga and Pseudomonas aeruginosa as causes of corneal keratitis in a contact lens wearer from Gauteng, South Africa, is reported. These two pathogens have previously been assumed to be selectively exclusive. Cysts of the isolated acanthameba tolerated an incubation temperature of 40 degrees C, indicating a pathogenic species. This case highlights the importance of culture methods in the diagnosis of corneal infection and the choice of treatment regimen. The patient's history of careless contact lens-disinfecting habits emphasizes the need to adhere strictly to recommended methods of contact lens care.  (+info)

Phylogenetic diversity among geographically dispersed Chlamydiales endosymbionts recovered from clinical and environmental isolates of Acanthamoeba spp. (7/141)

The recently proposed reorganization of the order Chlamydiales and description of new taxa are broadening our perception of this once narrowly defined taxon. We have recovered four strains of gram-negative cocci endosymbiotic in Acanthamoeba spp., representing 5% of the Acanthamoeba sp. isolates examined, which displayed developmental life cycles typical of members of the Chlamydiales. One of these endosymbiont strains was found stably infecting an amoebic isolate recovered from a case of amoebic keratitis in North America, with three others found in acanthamoebae recovered from environmental sources in North America (two isolates) and Europe (one isolate). Analyses of nearly full-length 16S rRNA gene sequences of these isolates by neighbor joining, parsimony, and distance matrix methods revealed their clustering with other members of the Chlamydiales but in a lineage separate from those of the genera Chlamydia, Chlamydophila, Simkania, and Waddlia (sequence similarities, <88%) and including the recently described species Parachlamydia acanthamoebae (sequence similarities, 91.2 to 93.1%). With sequence similarities to each other of 91.4 to 99.4%, these four isolates of intra-amoebal endosymbionts may represent three distinct species and, perhaps, new genera within the recently proposed family Parachlamydiaceae. Fluorescently labeled oligonucleotide probes targeted to 16S rRNA signature regions were able to readily differentiate two groups of intra-amoebal endosymbionts which corresponded to two phylogenetic lineages. These results reveal significant phylogenetic diversity occurring among the Chlamydiales in nontraditional host species and supports the existence of a large environmental reservoir of related species. Considering that all described species of Chlamydiales are known to be pathogenic, further investigation of intra-amoebal parachlamydiae as disease-producing agents is warranted.  (+info)

Heterogeneity in cyst morphology within isolates of Acanthamoeba from keratitis patients in Thailand. (8/141)

We isolated Acanthamoebae from the first two keratitis patients identified in Thailand in 1988 and 1990. The patients developed decreased vision, severe photophobia, severe eye pain and foreign body sensation after minor corneal trauma. The lesions included generalized superficial punctate keratitis, stromal corneal ulcer with keratic precipitate and uveitis in one case, and corneal ulcer with abscess in the other. Both cases were diagnosed by isolation of characteristic trophozoites and cysts of Acanthamoeba from corneal tissue by non-nutrient agar culture method. Based on cyst morphology, A. castellanii and A. polyphaga were detected in one case, and A. castellanii and A. triangularis in the other. Restriction fragment length polymorphism analysis of mitochondrial DNA (mtDNA-RFLP) revealed that each patient harboured a single parasite population. One shared mtDNA-RFLP with an authentic strain of A. castellanii, and the other gave a new unique pattern. Thus species identification of Acanthamoeba based on cyst morphology per se can be arbitrary, and mtDNA-RFLP may be more appropriate for accurate species/strain differentiation amongst morphologically heterogeneous populations of Acanthamoebae.  (+info)

We present eight cases of Acanthamoeba keratitis. In each case; the Acanthamoeba organisms were visualized in the epithelium and anterior stroma using tandem scanning confocal microscopy. The organisms were highly reflective, ovoid, and were 10-25 microns in diameter. The Acanthamoeba organisms in the human corneas were identical in size and shape to Acanthamoeba organisms on an agar plate visualized with the same confocal microscope. Confocal microscopy is a useful method for identifying Acanthamoeba organisms in vivo within the corneal epithelium and anterior stroma.

In the present study, three artificial tear brands were selected according to the preservative agents (detergent or oxidative) or the lack of them to study their possible amoebicidal activity against trophozoites, as this is the initial state of the infection.. To study the viability of Acanthamoeba trophozoites after incubation with these tears, two different methods were used. The more traditional one, Trypan Blue stain, allows the differentiation of amoebae with the altered cell membrane and thus, identification of the non-viable ones. The second method used CTC stain to measure mitochondrial activity to determine the viability of the amoebae. This stain was developed for bacterial viability and then, adapted for Acanthamoeba in fluorometry by Kobayashi et al. [23]. In the present study, CTC stain for Acanthamoeba viability was used with flow cytometry for the first time.. One of the artificial tears tested using these two methods was Optava Fusion™. It contains Purite®, which is a soft ...
LAMP was confirmed to be very sensitive, with the lowest detection limit being 10 copies/tube of Acanthamoeba DNA. The LAMP primers only amplified Acanthamoeba DNA. During the development of AK in mice, almost all of the positive rates of LAMP at each time point post-infection were higher than those of culture or corneal smear examination. The total positive rate of LAMP was significantly higher than those of culture and corneal smear examination (P,0.05), while the sensitivity of LAMP and real-time PCR was comparable. However, the trends of positive change in these different test methods were generally similar. Of the three clinical corneal specimens, two suspected AK were tested positive for Acanthamoeba using LAMP along with culture or corneal smear examination, while the other suspected fungal keratitis was tested negative.. ...

To our knowledge, this is the first study where two infected contact lenses in the same eye are used to induce AK in rabbits. Previously, van Klink et al.28 assessed the susceptibility of hamsters to reinfection in the noninfected contralateral eye, obtaining a 71% rate in the first infection (infected eye) and 75% in the reinfection (contralateral eye). Furthermore, Alizadeh et al.29 and Leher et al.30 rechallenged the infected eyes of pigs with a second or even a third contact lens, and in their control groups a 100% rate of infection was observed. In these studies, like in our group 2L-21d, the second lens was placed after the first complete keratitis resolution, but not in group 2L-3d, where it was performed in which the clinical signs still remained (sixth day). A similar infection rate was obtained using one (group 1L, 87.5%) or two (group 2L-21d, 100%, and group 2L-3d, 82.6%) lenses. However, unlike the fact desired in any infection model, the placement of only one lens was correlated ...

Pathogenic strains of the genus Acanthamoeba are causative agents of a serious sight-threatening infection of the eye known as Acanthamoeba keratitis. The prevalence of this infection has risen in the past 20 years, mainly due to the increase in number of contact lens wearers. In this study, the prevalence of Acanthamoeba in a risk group constituted by asymptomatic contact lens wearers from Tenerife, Canary Islands, Spain, was evaluated. Contact lenses and contact lens cases were analysed for the presence of Acanthamoeba isolates. The isolates' genotypes were also determined after rDNA sequencing. The pathogenic potential of the isolated strains was subsequently established using previously described molecular and biochemical assays, which allowed the selection of three strains with high pathogenic potential. Furthermore, the sensitivity of these isolates against two standard drugs, ciprofloxacin and chlorhexidine, was analysed. As the three selected strains were sensitive to chlorhexidine, its

Acanthamoeba spp. are microscopic organisms that can be found just about anywhere, from soil to water, to the air we breathe. They are the direct culprits of Acanthamoeba keratitis (AK) a relatively rare but sight-threatening disease which is actually caused by at least eight species of Acanthamoeba: A. castellanii, A. culbertsoni, A. polyphaga, A. hatchetti, A. rhysodes, A. lugdunesis, A. quina, and A. griffin. Ocular trauma and contaminated water are also associated with AK infections but it has been found that contact lens wearing accounts for , 80% of the cases. If found early the infection can be cured, but this gets progressively more difficult the longer it remains untreated. The difficulty lies with the life cycle of the Acanthamoeba species which consists of two stages: the trophozoite and the cyst ...

Another name for Acanthamoeba Infection is Acanthamoeba Infection. The evaluation of an acanthamoeba infection begins with a history and physical examination ...
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 ...
Acanthamoeba is a genus of amoebae, a single-celled eukaryote commonly recovered from soil, fresh water and other habitats. Acanthamoeba has two evolutive forms, the metabolically active trophozoite and a dormant, stress resistant cyst. Trophozoites are small, usually 15 to 35 μm in length and amoeboid in shape. In nature, Acanthamoeba species are free-living bacterivores, but in certain situations they can cause infections (Acanthamebiasis) in humans and other animals. Acanthamoeba spp. are among the most prevalent protozoa found in the environment. They are distributed worldwide, and have been isolated from soil, air, sewage, seawater, chlorinated swimming pools, domestic tap water, bottled water, dental treatment units, hospitals, air-conditioning units, and contact lens cases. Additionally, Acanthamoeba have been isolated from human skin, nasal cavities, throats, and intestines, as well as plants and other mammals. Diseases caused by Acanthamoeba include keratitis and granulomatous amoebic ...

Acanthamoeba keratitis is a rare but serious disease that, if undetected, can cause permanent corneal damage and result in blindness or significant loss in visual acuity. The ephemeral nature of AK outbreaks has reinforced the misconception that the disease is primarily the result of contaminated or otherwise faulty contact lens solutions. The reality is that the organism is common, and contact lens wearers must use good hygiene to minimize their risk. Patients need to understand that showering or swimming without removing their contacts may cost them their eyesight. Also, the upcoming report from the CDC should provide guidance in terms of the role public health officials can play. Ultimately, our response to AK outbreaks should focus on proper contact lens habits, and when needed, prompt diagnosis and treatment.. Dr. Abelson, a clinical professor of ...

New research published in the British Journal of Ophthalmology has highlighted an increase in the number of patients suffering from acanthamoeba keratitis
Acanthamoebiasis is most often found in patients with immune deficiency, with infections facilitated by the intake of immunosuppressive drugs. The host immune response to Acanthamoeba spp. infection is poorly understood. Thus, in this study, we aimed to examine the course of Acanthamoeba spp. infection taking into account the hosts immunological status, including assessment of the hematological parameters, cytokine analysis, immunophenotypic changes in spleen populations, and histological spleen changes, which could help clarify some aspects of the immune response to acanthamoebiasis. In our experimental study, we used Acanthamoeba strain AM 22 isolated from the bronchoaspirate of a patient with acute myeloid leukaemia (AML) and atypical pneumonia symptoms. Acanthamoeba spp. affected the hematological parameters in immunocompetent and immunosuppressed mice and induced a change in spleen weight during infection. Moreover, analysis of anti-inflammatory (IL-4 and IL-10) and pro-inflammatory (IL-17A and

Suboptimal agreement between molecular assays for the detection of Acanthamoeba spp. in clinical specimens has been demonstrated, and poor assay sensitivity directly imperils the vision of those affected by amoebic keratitis (AK) through delayed diagnosis. We sought to develop and validate a single Taqman real time PCR assay targeting the Acanthamoeba 18S rRNA gene that could be used to enhance sensitivity and specificity when paired with reference assays. Biobanked DNA from surplus delinked AK clinical specimens and 10 ATCC strains of Acanthamoeba was extracted. Sequence alignment of 66 18S rRNA regions from 12 species of Acanthamoeba known to cause keratitis informed design of a new TaqMan primer set. Performance of the new assay was compared to the 2 assays used currently in our laboratory. Among 24 Acanthamoeba-positive and 83 negative specimens by the CDC reference standard, performance characteristics of the newly designed primer set were as follows: sensitivity 100%, specificity 94%, PPV 82.8%,
Propionibacterium acnes growth in 1 of 1 vial; no fungal or aerobic growth. A history of continuous soft contact lens wear, discomfort out of proportion to the exam findings, and marked radial perineuritis suggested Acanthamoeba keratitis in this patient.. A corneal epithelial scraping was obtained for culture and histopathologic exam along with tear samples for viral PCR testing, though neither was diagnostic. A bandage contact lens was placed for comfort, and erythromycin drops were started four times a day in the left eye for bacterial prophylaxis. Anti-acanthamoebic medication was not started hnoey light of her current pregnancy and the concern for category risk drops the fetus.. We assisted her in establishing care with an obstetrician urgently to assess the health of the fetus and to pregnancy recommendations ete the risks of systemic absorption and placental transfer of topical anti-acanthamoebic ophthalmic medications.. Three days later, the patient returned for a follow-up visit. ...
We have studied the kinetics of the gelation process that occurs upon warming cold extracts of Acanthamoeba using a low-shear falling ball assay. We find that the reaction has at least two steps, requires 0.5 mM ATP and 1.5 mM MgCl2, and is inhibited by micromolar Ca++. The optimum pH is 7.0 and temperature, 25 degrees-30 degrees C. The rate of the reaction is increased by cold preincubation with both MgCl2 and ATP. Nonhydrolyzable analogues of ATP will not substitute for ATP either in this potentiation reaction or in the gelation process. Either of two purified or any one of four partially purified Acanthamoeba proteins will cross-link purified actin to form a gel, but none can account for the dependence of the reaction in the crude extract on Mg-ATP or its regulation by Ca++. This suggests that the extract contains, in addition to actin-cross-linking proteins, factors dependent on Mg-ATP and Ca++ that regulate the gelation process. ...

Veliko malih plazilcev kot so kače in kuščarji, ki živijo na tleh ali v vodi so ranljivi, ker na njih prežijo raznovrstne mesojede živali. Tako je izogibanje najpogostejša oblika obrambe plazilcev.[19] Ob prvem znaku nevarnosti se večina kač in kuščarjev odplazi v podrast, želve in krokodili pa se potopijo v vodo in tako izginejo iz vidnega polja. Plazilci se lahko izogejo soočenju s prikrivanjem (kamuflažo). Z uporabo različnih barv sive, zelene in rjave se lahko te živali presenetljivo dobro zlijejo z ozadjem njihovega naravnega okolja.[20] Nekateri celo spreminjajo barvo in risbe na telesu in se tako lažje prikrivajo. Takšno menjavanje barv temelji na premikanju barvil, širjenju in oženju pigmentnih celic v koži.[1] Če se nevarnost pojavi tako nenadoma, tako da je pobeg lahko nevaren, krokodili, želve, nekateri kuščarji in kače glasno sikajo pri soočenju s sovražnikom.

Informovanosť pacientov po prekonanom IM o nutnosti zmeny životného štýlu s uplatňovaním režimových opatrení v rámci sekundárnej prevencie je vysoká - prakticky všetci po infarkte vedia, že svoj životný štýl musia zmeniť. Napriek tomu sa snaží o zmenu životného štýlu len ich časť. Možno sa len domnievať, že jedným z dôvodov je aj to, že napriek poučeniu takmer všetkých probandov sa takmer polovica z nich v dotazníku priznala k tomu, že ich kompletne nepozná, resp. sedmina probandov o nich nevie nič - 2× viac mužov ako žien, častejšie starší pacienti ako mladší. Možno to reflektuje všeobecný záujem, resp. nezáujem skôr mužov ako žien v zdravej populácii o svoje zdravie.. S tým úzko súvisí aj samotné dodržiavanie režimových opatrení. Väčší vzťah k ich dodržiavaniu majú ženy, vo všeobecnosti sú disciplinovanejší hlavne mladší pacienti. S nedostatočným dodržiavaním režimových opatrení môže súvisieť aj ...
