The microsporidian spore invasion tube. The ultrastructure, isolation, and characterization of the protein comprising the tube. (1/228)

The extrusion apparatus of the microsporidian parasitic protozoan Nosema michaelis discharges an invasion (or polar) tube with a velocity suitalbe for piercing cells and injecting infective sporoplasm. The tube is composed of a polar tube protein (PTP) which consists of a single, low molecular weight polypeptide slightly smaller than chymotrypsinogen-A. Assembled PTP tubes resist dissociation in sodium dodecyl sulfate and brief exposures in media at extreme ends of the pH range; however, the tubes are reduced by mercaptoethanol and dithiothreitol. When acidified, mercaptoethanol-reduced PTP self-assembles into plastic, two-dimensional monolayers. Dithiothreitol-reduced PTP will not reassemble when acidified. Evidence is presented which indicates that PTP is assembled as a tube within the spore; that the ejected tube has plasticity during sporoplasm passage; and, finally, that the subunits within the tube polymer are bound together, in part, by interprotein disulfide linkages.  (+info)

Antibody-dependent cell-mediated cytotoxicity in cattle: activity against 51Cr-labeled chicken erythrocytes coated with protozoal antigens. (2/228)

Bovine mononuclear cells in the presence of bovine anti-chicken erythrocyte sera at high dilutions induce release of chromium-51 from labeled chicken erythrocytes. Bovine effector cells are capable of recognizing both bovine immunoglobulin G(1) and bovine immunoglobulin G(2); in contrast, human effector cells only recognize immunoglobulin G(1). Effector cell activity of bovine mononuclear cells is equally distributed between peripheral blood and spleen. As in other species, thymus and lymph node cells exert no antibody-dependent effect, although some direct cytotoxicity by lymph node cells may be observed. Antibody-dependent cell-mediated cytotoxicity against a bovine cell line can also be detected. By using a tannic acid technique, it was found that chicken erythrocytes coated with Theileria parva piroplasm antigen or with Trypanosoma rhodesiense variant-specific coat antigen form suitable targets for bovine antibody-dependent cell-mediated cytotoxicity assays. By using such targets, a moderate degree of direct cytotoxicity by bovine mononuclear cells, in the absence of antibody, is always observed; this may be reduced by choosing optimal conditions of tannic acid treatment and antigen sensitization and by the use of short incubation periods for the cytotoxicity assay. Observations have been made on the variant specificity, time course of appearance, and association with immunoglobulin G(1) of the antibody activity responsible for cell-dependent cytotoxicity against chicken erythrocytes coated with T. rhodesiense antigens. The potential usefulness of this technique in the analysis of protective immune responses against protozoal infections is discussed.  (+info)

Perkinsus marinus extracellular protease modulates survival of Vibrio vulnificus in Eastern oyster (Crassostrea virginica) hemocytes. (3/228)

The in vitro effects of the Perkinsus marinus serine protease on the intracellular survival of Vibrio vulnificus in oyster hemocytes were examined by using a time-course gentamicin internalization assay. Results showed that protease-treated hemocytes were initially slower to internalize V. vulnificus than untreated hemocytes. After 1 h, the elimination of V. vulnificus by treated hemocytes was significantly suppressed compared with hemocytes infected with invasive and noninvasive controls. Our data suggest that the serine protease produced by P. marinus suppresses the vibriocidal activity of oyster hemocytes to effectively eliminate V. vulnificus, potentially leading to conditions favoring higher numbers of vibrios in oyster tissues.  (+info)

Conservation of a gliding motility and cell invasion machinery in Apicomplexan parasites. (4/228)

Most Apicomplexan parasites, including the human pathogens Plasmodium, Toxoplasma, and Cryptosporidium, actively invade host cells and display gliding motility, both actions powered by parasite microfilaments. In Plasmodium sporozoites, thrombospondin-related anonymous protein (TRAP), a member of a group of Apicomplexan transmembrane proteins that have common adhesion domains, is necessary for gliding motility and infection of the vertebrate host. Here, we provide genetic evidence that TRAP is directly involved in a capping process that drives both sporozoite gliding and cell invasion. We also demonstrate that TRAP-related proteins in other Apicomplexa fulfill the same function and that their cytoplasmic tails interact with homologous partners in the respective parasite. Therefore, a mechanism of surface redistribution of TRAP-related proteins driving gliding locomotion and cell invasion is conserved among Apicomplexan parasites.  (+info)

Cryptosporidium parvum appears to lack a plastid genome. (5/228)

Surprisingly, unlike most Apicomplexa, Cryptosporidium parvum appears to lack a plastid genome. Primers based upon the highly conserved plastid small- or large-subunit rRNA (SSU/LSU rRNA) and the tufA-tRNAPhe genes of other members of the phylum Apicomplexa failed to amplify products from intracellular stages of C. parvum, whereas products were obtained from the plastid-containing apicomplexans Eimeria bovis and Toxoplasma gondii, as well as the plants Allium stellatum and Spinacia oleracea. Dot-blot hybridization of sporozoite genomic DNA (gDNA) supported these PCR results. A T. gondii plastid-specific set of probes containing SSU/LSU rRNA and tufA-tRNA(Phe) genes strongly hybridized to gDNA from a diverse group of plastid-containing organisms including three Apicomplexa, two plants, and Euglena gracilis, but not to those without this organelle including C. parvum, three kinetoplastids, the yeast Saccharomyces cerevisiae, mammals and the eubacterium Escherichia coli. Since the origin of the plastid in other apicomplexans is postulated to be the result of a secondary symbiogenesis of either a red or a green alga, the most parsimonious explanation for its absence in C. parvum is that it has been secondarily lost. If confirmed, this would indicate an alternative evolutionary fate for this organelle in one member of the Apicomplexa. It also suggests that unlike the situation with other diseases caused by members of the Apicomplexa, drug development against cryptosporidiosis targeting a plastid genome or metabolic pathways associated with it may not be useful.  (+info)

Sex allocation and population structure in apicomplexan (protozoa) parasites. (6/228)

Establishing the selfing, rate of parasites is important for studies in clinical and epidemiological medicine as well as evolutionary biology Sex allocation theory offers a relatively cheap and easy way to estimate selfing rates in natural parasite populations. Local mate competition (LMC) theory predicts that the optimal sex ratio (r*; defined as proportion males) is related to the selfing rate (s) by the equation r* = (1-s)/2. In this paper, we generalize the application of sex allocation theory across parasitic protozoa in the phylum Apicomplexa. This cosmopolitan phylum consists entirely of parasites, and includes a number of species of medical and veterinary importance. We suggest that LMC theory should apply to eimeriorin intestinal parasites. As predicted, data from 13 eimeriorin species showed a female-biased sex ratio, with the sex ratios suggesting high levels of selfing (0.8-1.0). Importantly, our estimate of the selfing rate in one of these species, Toxoplasma gondii, is in agreement with previous genetic analyses. In contrast, we predict that LMC theory will not apply to the groups in which syzygy occurs (adeleorins, gregarines and piroplasms). Syzygy occurs when a single male gametocyte and a single female gametocyte pair together physically or in close proximity, just prior to fertilization. As predicted, data from four adeleorin species showed sex ratios not significantly different from 0.5.  (+info)

Extraction-free, filter-based template preparation for rapid and sensitive PCR detection of pathogenic parasitic protozoa. (7/228)

Within the last several years, the protozoan parasites Cyclospora cayetanensis, Cryptosporidium parvum, and microsporidia have become recognized as important, rapidly emerging human pathogens in immunocompromised and immunocompetent individuals. Since the early 1990s, many of the reported outbreaks of enteric illness caused by these microorganisms have been attributed to food- and water-borne contamination. Many inherent obstacles affect the success of current surveillance and detection methods used to monitor and control levels of contamination by these pathogens. Unlike methods that incorporate preenrichment for easier and unambiguous identification of bacterial pathogens, similar methods for the detection of parasitic protozoa either are not currently available or cannot be performed in a timely manner. We have developed an extraction-free, filter-based protocol to prepare DNA templates for use in PCR to identify C. cayetanensis and C. parvum oocysts and microsporidia spores. This method requires only minimal preparation to partially purify and concentrate isolates prior to filter application. DNA template preparation is rapid, efficient, and reproducible. As few as 3 to 10 parasites could be detected by PCR from direct application to the filters. In studies, as few 10 to 50 Encephalitozoon intestinalis spores could be detected when seeded in a 100-microliter stool sample and 10 to 30 C. cayetanensis oocysts could be detected per 100 g of fresh raspberries. This protocol can easily be adapted to detect parasites from a wide variety of food, clinical, and environmental samples and can be used in multiplex PCR applications.  (+info)

Food-borne protozoa. (8/228)

Pathogenic protozoa are commonly transmitted to food in developing countries, but food-borne outbreaks of infection are relatively rare in developed countries. The main protozoa of concern in developed countries are Toxoplasma, Cryptosporidium and Giardia, and these can be a problem in immunocompromised people. Other protozoa such as Entamoeba histolytica, Cyclospora cayetanensis and Sarcocystis can be a food-borne problem in non-industrialised countries. C. cayetanensis has emerged as a food-borne pathogen in foods imported into North America from South America. Microsporidia may be food-borne, although evidence for this is not yet available. The measures needed to prevent food-borne protozoa causing disease require clear assessments of the risks of contamination and the effectiveness of processes to inactivate them. The globalisation of food production can allow new routes of transmission, and advances in diagnostic detection methods and surveillance systems have extended the range of protozoa that may be linked to food.  (+info)

The first Apicomplexa protozoan was seen by Antonie van Leeuwenhoek, who in 1674 saw probably oocysts of Eimeria stiedae in the gall bladder of a rabbit. The first species of the phylum to be described, Gregarina ovata in earwigs intestines, was named by Dufour in 1828. He thought that they were a peculiar group related to the trematodes, at that time included in Vermes.[26] Since then, many more have been identified and named. During 1826-1850, 41 species and six genera of Apicomplexa were named. In 1951-1975, 1873 new species and 83 new genera were added.[26]. The older taxon Sporozoa, included in Protozoa, was created by Leuckart in 1879[27] and adopted by Bütschli in 1880.[28] Through history, it grouped with the current Apicomplexa many unrelated groups. For example, Kudo (1954) included in the Sporozoa species of the Ascetosporea (Rhizaria), Microsporidia (Fungi), Myxozoa (Animalia), and Helicosporidium (Chlorophyta), while Zierdt (1978) included the genus Blastocystis ...

Apicomplexa are intracellular parasites that cause important human diseases including malaria and toxoplasmosis. During host cell infection new parasites are formed through a budding process that parcels out nuclei and organelles into multiple daughters. Budding is remarkably flexible in output and can produce two to thousands of progeny cells. How genomes and daughters are counted and coordinated is unknown. Apicomplexa evolved from single celled flagellated algae, but with the exception of the gametes, lack flagella. Here we demonstrate that a structure that in the algal ancestor served as the rootlet of the flagellar basal bodies is required for parasite cell division. Parasite striated fiber assemblins (SFA) polymerize into a dynamic fiber that emerges from the centrosomes immediately after their duplication. The fiber grows in a polarized fashion and daughter cells form at its distal tip. As the daughter cell is further elaborated it remains physically tethered at its apical end, the conoid ...

The total number of kinases, i.e. the kinome size, is markedly reduced in P. falciparum and other apicomplexans in comparison with other model eukaryotes. This reduction of the kinome is in line with an overall gene loss observed in the Plasmodium genome. Gene loss and general compaction of the genome (loss of introns, smaller intergenic regions) have been noted as the dominant mode of genomic evolution in obligate intracellular parasites such as the Apicomplexa [76] (see figure 3 for a comparison of ePK group counts across eukaryotes). From a superficial comparison, the kinome of P. falciparum, consisting of roughly 91 ePKs [24] plus at least five aPKs [22], appears to constitute a percentage of the total proteome (1.7% of 5228 protein-coding genes) that is similar to that found in other, non-parasitic eukaryotes: the kinome of the bakers yeast Saccharomyces cerevisiae comprises 117 ePKs (2% of 5770 genes; plus 14 or 10 aPKs, depending on the study) [77,78], the fruitfly Drosophila ...
Users of the eukaryotic phylum Apicomplexa are the cause of important human being diseases including malaria toxoplasmosis and cryptosporidiosis. transgenic parasite lines expressing epitope-tagged centromeric H3 variant CenH3 we determine the centromeres of chromosomes by hybridization of chromatin immunoprecipitations to genome-wide microarrays (ChIP-chip).

Centromere sequestration provides a mechanism for Meloxicam (Mobic) the organization of the nucleus and the maintenance of genome integrity. tachyzoites featuring the simplest form endodyogeny bud into two daughters after each round of DNA replication (3). the causative agent of malaria divides by schizogony whereby the cell proceeds through several rounds of DNA replication and mitosis before the right now multinucleate schizont gives rise to multiple zoites at ...

Reef-building corals house many symbiotic microorganisms that are capable of photosynthesis. For example, Symbiodinium dinoflagellates from the genus Symbiodiniaceae outnumber corallicolids in their hosts. These algae not only perform photosynthesis, they also support the health of their hosts.. While corallicolids are the most common apicomplexans in coral reefs and the second most common microorganisms in coral microbiota, they are only getting studied now.. Like other apicomplexans, corallicolids possess a plastid, a chamber within a cell. In photosynthetic algae and plants, the plastid hosts the process of turning light into food, which requires chlorophyll and certain proteins.. Analysis of the plastid in corallicolids show that it contains all four ancestral genes involved in the production of chlorophyll. However, it doesnt have any of the genes that encode for photosystem proteins which conduct photosynthesis.. We dont know why these organisms are holding on to these photosynthesis ...

Intracellular calcium levels and calcium ion (Ca2+) signaling regulate host cell invasion, egress, protein secretion, and differentiation in apicomplexan parasites (1, 2). The biology controlling central aspects of Ca2+ entry, storage, release, and signaling has come under increased scrutiny due to the central importance of Ca2+ signaling in mediating the cellular and developmental changes essential to apicomplexan parasitism. While a family of calcium (Ca2+)-dependent serine/threonine (S/T) protein kinases (CDPKs) is present in plants, ciliates, green algae, and the apicomplexan parasites (2), CDPKs are absent in the mammalian hosts of apicomplexan parasites, suggesting that this gene family could be a rich source of potential drug targets (3). Surprisingly, the CDPK gene family is greatly expanded in apicomplexan parasites, and Toxoplasma gondii carries genes that encode 14 distinct CDPKs, though the functions of most of these CDPK genes have not been previously elucidated. ln this issue of ...
Surprisingly, some of the worlds most dangerous parasites appear to have had a benign photosynthetic past in the ocean. The phylum Apicomplexa includes the causative agents of malaria and a number of additional human and animal diseases. These diseases threaten the life and health of hundreds of millions each year and pose a tremendous challenge to public health. Recent findings suggest that Apicomplexa share their ancestry with diatoms and kelps, and that a key event in their evolution was the acquisition of a red algal endosymbiont. A remnant of this endosymbiont is still present today, albeit reduced to a small chloroplast-like organelle, the apicoplast. In the present chapter, I introduce the remarkably complex biology of this organelle. The apicoplast is bounded by four membranes, and these membranes trace their ancestry to three different organisms. Intriguingly, this divergent ancestry is still reflected in their molecular makeup and function. We also pursue the raison dêtre of the ...
Apicomplexans are responsible for major human diseases such as toxoplasmosis caused by Toxoplasma gondii (T. gondii) and the deadliest form of malaria caused by Plasmodium falciparum (P. falciparum). The genomes of these pathogens are now sequenced ushering in a new era of drug development. A major hurdle to exploiting this genome resource is that a large number of the encoded genes are hypotheticals and have yet to be characterized. Hypothetical proteins comprise roughly half of the predicted gene complement of T. gondii and P. falciparum and represent the largest class of uniquely functioning proteins in these parasites. Following the idea that functional relationships can be informed by the timing of gene expression, we devised a strategy to identify the core set of apicomplexan cell division cycling genes with important roles in parasite division, which includes many uncharacterized proteins. We assembled an expanded list of orthologs from the T. gondii and P. falciparum genome sequences (2781

N2 - Parasites of the Apicomplexa phylum, such as Plasmodium spp. and Toxoplasma gondii, undergo complex life cycles involving multiple stages with distinct biology and morphologies. Post-translational modifications (PTMs), such as phosphorylation, acetylation and glycosylation, regulate numerous cellular processes, playing a role in every aspect of cell biology. PTMs can occur on proteins at any time in their lifespan and through alterations of target protein activity, localization, protein-protein interactions, among other functions, dramatically increase proteome diversity and complexity. In addition, PTMs can be induced or removed on changes in cellular environment and state. Thus, PTMs are likely to be key regulators of developmental transitions, biology ...

The comparative genomics of apicomplexans, such as the malarial parasitePlasmodium, the cattle parasite Theileria and the emerging human parasiteCryptosporidium, have suggested an unexpected paucity of specifictranscription factors (TFs) with DNA binding domains that are closelyrelated to those found in the major families of TFs from other eukaryotes.This apparent lack of specific TFs is paradoxical, given that theapicomplexans show a complex developmental cycle in one or more hosts anda reproducible pattern of differential gene expression in course of thiscycle. Using sensitive sequence profile searches, we show that theapicomplexans possess a lineage-specific expansion of a novel family ofproteins with a version of the AP2 (Apetala2)-integrase DNA bindingdomain, which is present in numerous plant TFs. About 20-27 members ofthis apicomplexan AP2 (ApiAP2) family are encoded in differentapicomplexan genomes, with each protein containing one to four copies ofthe AP2 DNA binding domain. Using gene ...

Ancient algae might keep crucial to treating malaria and related parasites By Helen Albert, Senior medwireNews Reporter Researchers can see that parasites of the Apicomplexa taxon, such as Plasmodium falciparum and Toxoplasma gondii, reproduce within sponsor cells using a framework that evolved from a flagellum. Notably, the team also found that genetic disruption of the framework of this fiber prevented effective replication taking place in T minor problem . Gondii. These altered parasites can in the beginning infect cells, but after we turn off the fibers genes, they can not create new child cells and spread, explained study writer Maria Francia, from the University of Georgia, Athens, USA, in a press statement. Because it cannot replicate, the parasite dies without causing serious damage eventually.

The Protista Kingdom contains all organisms that cannot be classified as fungi, true plants or animals. The range and variety of organisms in this kingdom is huge! Some protists are more closely related to plants, fungi, or animals than they are to other protists. Biologists cannot agree on how to classify these organisms, and some scientists have now split the Protista Kingdom into as many as 20 different kingdoms. The term protist is still used as a convenient way to refer to eukaryotes that are neither plants, animals, or fungi ...
If you are referring to the taxonomic classification, true bacteria are in the kingdom Monera. There are five kingdoms which include Animalia, Plantae, Fungi, Protista, and Monera. The first three are pretty self explanatory, the third, Protista, has a variety of fairly primitive organisms that cant be classified under any of the other kingdoms, while Monera includes single cell organisms such as bacteria and blue-green algae.. ...

Unlike Opisthokonta lineages (such as yeasts and metazoans), several otherwise conserved key components of mRNA export are not found in the genomes of the Chromalveolata and Excavata lineages, including several species of parasites [11, 12]. Our bioinformatic analysis of Apicomplexa (Additional file 1: Table S1) corroborates previous work suggesting the presence of either highly divergent or unique components for mRNA export in these parasites. Figure 1b shows an overview of the few conserved components of mRNA export in the Apicomplexa, and the relevance of those findings are discussed below.. The major and specific mRNA complex (TREX) may not be conserved in the genomes of the three apicomplexan parasites we analyzed. These genomes contain only a homolog for UAP56 and lack a homolog for REF/Aly as well as for most THO complex components, with the exception of Tho2 (Additional file 1: Table S1). Similar to TREX, several homologs for components of the TREX-2 complex were not identified in these ...

The carapace and appendages of G. roeselii were often coated with stalked ciliates and epibiotic rotifers (Fig. 1a), however the gills and brood pouch were commonly associated with all epibiotic commensals. None of the epibiotic commensals induced an immune response from the host and were common throughout the G. roeselii population (Table 2).. A single animal was observed with a ciliated protist infection in the haemolymph, with accumulations of the parasite in the antennal gland, gills (Fig. 1d), heart and appendages. No immune response toward the parasitic protist was noted throughout the histological screen.. Gregarines (Apicomplexa) were commonly associated with the gut (50% prevalence) (Fig. 1e) and less frequently, the hepatopancreatic tubules (, 1%). Gregarines were often seen in large numbers in the gut with both extracellular and intracellular developmental stages with occasional observation of syzygy. Gregarines elicited no apparent immune response from the host but were detected in ...
The genome of the protozoan parasite Toxoplasma gondii was found to contain two genes encoding tyrosine hydroxylase; that produces l-DOPA. The encoded enzymes metabolize phenylalanine as well as tyrosine with substrate preference for tyrosine. Thus the enzymes catabolize phenylalanine to tyrosine and tyrosine to l-DOPA. The catalytic domain descriptive of this class of enzymes is conserved with the parasite enzyme and exhibits similar kinetic properties to metazoan tyrosine hydroxylases, but contains a unique N-terminal extension with a signal sequence motif. One of the genes, TgAaaH1, is constitutively expressed while the other gene, TgAaaH2, is induced during formation of the bradyzoites of the cyst stages of the life cycle. This is the first description of an aromatic amino acid hydroxylase in an apicomplexan parasite. Extensive searching of apicomplexan genome sequences revealed an ortholog in Neospora caninum but not in Eimeria, Cryptosporidium, Theileria, or Plasmodium. Possible role(s) of these
Phosphoinositides (PIs) and their derivatives are essential cellular components that form the building blocks for cell membranes and regulate numerous cell functions. Specifically, the ability to generate myo-inositol 1,4,5-trisphosphate (InsP3) via phospholipase C (PLC) dependent hydrolysis of phosphatidylinositol 4,5-bisphosphate (PIP2) to InsP3 and diacylglycerol (DAG) initiates intracellular calcium signaling events representing a fundamental signaling mechanism dependent on PIs. InsP3 produced by PI turnover as a second messenger causes intracellular calcium release, especially from endoplasmic reticulum, by binding to the InsP3 receptor (InsP3R). Various PIs and the enzymes, such as phosphatidylinositol synthase and phosphatidylinositol 4-kinase, necessary for their turnover have been characterized in Apicomplexa, a large phylum of mostly commensal organisms that also includes several clinically relevant parasites. However, InsP3Rs have not been identified in genomes of apicomplexans, ...
Chromera velia is an autotrophic protist isolated from stony corals. C. velia possesses a chloroplast thought to be most closely related to the apicoplasts of non-photosynthetic apicomplexa. . The ventral side of the flagellated C. velia cell has two grooves extending from the anterior flagella insertion point with a ridge rising towards the anterior apex of the cell. The anterior flagellum is shorter than the posterior flagellum and possesses a distinct, small curved appendage. The insertion point of the anterior flagellum is partly enclosed by a flap extending from the cell. The posterior flagellum is approximately four times the length of the cell and possesses mastigonemes. ...

Paua is a New Zealand summer delicacy. When someone says paua fritter they are usually referring to something made from blackfoot paua. The blackfoot paua (Haliotis iris) species is endemic to New Zealand and found throughout the country. It is most abundant on shallow reefs.. Paua belong to a group of primitive gastropod molluscs known as abalone. Worldwide there are about 55 species.. Three species of abalone occur in New Zealand: blackfoot paua (Haliotis iris), yellowfoot paua (Haliotis australis), and whitefoot paua (Haliotis virginea).. Blackfoot paua has a beautifully coloured shell; haliotis means sea ear and iris refers to the rainbow colour.. The hard shell is well adapted to living on rocks being battered by big surf. Although most paua live in water less than 10 metres deep, they may be found down to 15 metres, particularly in places exposed to large oceanic swells.. They feed by the backwards and forwards motion of their ribbon-like tongue and 100-150 rows of teeth. Small paua rasp ...
ApiCOWplexa is an informal network for scientists, veterinarians, students and others that are interested in apicomplexan parasites causing disease in farm animals, including Babesia, Besnoitia, Cryptosporidium, Eimeria, Gregarina, Neospora, Sarcocystis, Theileria and Toxoplasma. The aim is to foster interactions and scientific exchange on a range of topics such as diagnostics, epidemiology and economic impact of these parasites, biodiversity and population genetics, functional -omics and bioinformatics, host-parasite interactions, vaccines and chemotherapeutical options ...
While the four major species of Plasmodium differ in some ways from each other, they all share the same complex life cycle involving the insect (mosquito) vector and the human host. When an infected Anophele mosquito bites a human, sporozoites are injected with the saliva. The sporozoites are 10 -15 µm in length and about 1 µm in diameter. They have a thin outer membrane, a double inner membrane below which lies the subpelicular microtubules. They have 3 polar rings and the rhoptries are long, extending half the length of the body. The micronemes, convoluted elongate bodies, run forward to the anterior of the sporozoite entering a common duct with the rhoptries. Mitochondria are located at the posterior end. After entering the circulatory system, the sporozoites make quick work of invading liver cells using the apical organelles (characteristic of all apicomplexans; for more details, see Apicomplexa). Inside the hosts liver cell the Plasmodium cell undergoes asexual replication. The products ...

Author Summary The phylum Apicomplexa includes a number of medically and agriculturally relevant parasites. These include the Plasmodium species, agents of malaria and estimated to cause over 1 million deaths per year, and Toxoplasma gondii, which infects 30-80% of any human population. These parasites rely on a unique form of actomyosin-powered motility to perpetuate infection, but the molecular mechanisms regulating this vital process are virtually unknown. Here, we describe a plant-like Ca2+-dependent kinase of T. gondii, TgCDPK3, which is involved in the rapid activation of egress from host cells during Ca2+ signaling. T. gondiis requirement for TgCDPK3 seems to rely specifically on the local ionic environment, being dispensable in conditions typical of the extracellular environment. Activity is also dependent on localization to the parasite plasma membrane, which appears to be conferred by a consensus motif at the kinase N-terminus that is typically acylated. This work provides some of the first
In Toxoplasma gondii, an intracellular parasite of the phylum Apicomplexa, two isoforms of enolase (ENO1 and ENO2) are expressed in stage-specific manner. ENO2 is expressed only in rapidly growing tachyzoites, while ENO1 is in slowly growing bradyzoites. Interestingly, the localization of ENO1 and ENO2 in the nuclear compartment has suggested possible roles of the proteins in gene regulation and/or cell cycle. To understand the physiological role of ENO2 in T. gondii, the expression of ENO2 was silenced using a homologous gene silencing procedure. The introduction or expression of ENO2 dsRNA successfully silenced the expression of ENO2 at the levels of transcripts and proteins. While there was no change in the growth rate of both tachyzoites and bradyzoites, a subtle phenotypic change was observed in the localization of the ENO1 gene product in the bradyzoite stage.
Eimeriorina is a suborder of phylum Apicomplexa.[1][2] All species in this clade are homoxenous or facultatively homoxenous. Merogony, gamogony and oocyst formation all occur within the same host. The hosts may be vertebrates or invertebrates. Erroneous identifications of species is a major problem in coccidian systematics and it is likely that some of the genera and species will be revised. ...

I havent updated you on our poopy situation because I was so fed up that I didnt want to talk about it. The lab results came eventually and revealed that they had oocysts in their poop. As far as I understood, this means that they have/had Apicomplexa, a parasite. Like Giardia this parasite doesnt always cause symptoms, so theyve most likely had it for a longer time. The vet assumes that the stress of moving to my place has triggered the outburst. This diagnosis also explains why the diarrhea actually stopped by itself, because cats can sometimes handle this parasite on their own.. The shelter warned me that it was extremely difficult to give these pills; they even recommended that I would return my girls for 2 weeks to the shelter!. I refused. Of course Id give them to the shelter (or a clinic) if they needed e.g. syringes - but certainly not because of pills. It would have been the easiest solution for me, but for Tessa and Kajsa the worst: either way, they would have gotten the dreadful ...

Depending on your view of phylogenetics, a recent publication in Nature reporting the discovery of a new kingdom-level branch on the tree of life, basal to Kingdom Fungi, is either a major revision of our current view of taxonomy or completely unsurprising and expected. While we mostly refer to the four kingdoms within Domain Eukarya as Protista, Plantae, Fungi, and Animalia, its understood by the scientific community that Protista is essentially a catch-all category, not a true clade, for eukaryotes that dont quite fit into the other three groups. While this is convenient for organization, it fails to adequately express the diversity of protists. Four kingdoms is a useful system, but theres no reason why diversity at the kingdom level couldnt be much higher. A strict cladist could create hundreds, if not thousands of kingdoms from Protista alone.. Its not only splitters that get in on the action either. Some taxonomists have argued that Fungi and Animalia are part of a single kingdom, ...

● Protists are usually single celled organisms. ● Live in moist environments. ● Vary in the ways they move and obtain energy. Protists obtain their energy in several ways. ● Animal-like protists ingest or absorb food after capturing or trapping it. ● Plant-like protists produce food through photosynthesis. ● Fungus-like protists obtain their food by external digestion either as decomposers or as parasites. ● Some protists have both autotrophic and heterotrophic characteristics.

Tandem repeats (TRs) are frequently not perfect, containing a number of mutations accumulated during evolution. One of the main problems is to distinguish between the sequences that contain highly imperfect TRs and the aperiodic sequences. The majority of proteins with TRs in sequences have repetitive arrangements in their 3D structures. Therefore, the 3D structures of proteins can be used as a benchmarking criterion for TR detection in sequences. Different TR detection tools use their own scoring procedures to determine the boundary between repetitive and non-repetitive protein sequences. Here we described these scoring functions and benchmark them by using known structural TRs. Our survey shows that none of the existing scoring procedures are able to achieve an appropriate separation between genuine structural TRs and non-TR regions. This suggests that if we want to obtain a collection of structurally and functionally meaningful TRs from a large scale analysis of proteomes, the TR scoring ...
A system of broad classification which recognized a plant kingdom of four divisions and an animal kingdom of ten to fifteen phyla was for many years stable and standardized. Significant changes have occurred, or are now proposed. Among these, three major lines of development are discussed: a. Classification of the algae has been fundamentally revised; seven or more algal series are distinguished primarily by characteristics of cells. The phylum concept, long established in zoological classification, has been brought into botanical classification in the systems of Pascher (1931) and Tippo (1942), in which the major algal series, the Bryophyta, and the Tracheophyta are regarded as phyla. b. Many authors have advocated recognition of kingdom of lower organisms, to meet the difficulty of dividing these between the plant and animal kingdoms. Two major possibilities for such a third kingdom are the Protista of Haeckel (1866, 1894), essentially identified with the unicellular organisms, and the Proctoctista of

I would say this comment is off topic, but actually not. All the steps that you do constructing a house would not happen if you did not design and build it. It would not build itself. And yet a single cell organism is much more complicated than a house. It is just not at all intelligent to think life evolved randomly. There is a whole theory of how animals evolved from a single cell, to a fish, that crawled out of the sea etc. What is never mentioned is how did plants evolve? How did fungi evolve? The random formation of one type of life is in the statistically impossible mathematics zone, and yet we are talking about three separate formations of life. Animal, Plant, Fungi. Truly, there are also 3 other forms of life accepted by science: Protista, Eubacteria, Archaebacteria. So we are now up to six separate forms of life, that must beat the statistical odds and evolve separately ...

Bobcats become persistent carriers of the organism after they develop mild or subclinical infection and then serve as the reservoir host.[1][2][3][4] C. felis is transmitted by the Lone star tick (Amblyomma americanumm) that feeds on an infected bobcat then transmits the organism to another bobcat, or to a pet cat.[9] Many other types of ticks may feed on the cats but the only other tick that has been shown to transmit the organism is the American dog tick (Dermacentor variabilis) but only in a research setting.[1][4][9] In the past domestic cats were thought to always die from infection so they were considered terminal hosts or "dead end hosts".[3] Now there have been documented cases of cats that get sick and survive the infection and even those that never shown clinical signs at all.[1][4][8][9] Cats cannot catch the infection from another cat directly without being bitten by a tick. The life cycle of the protozoa has a ...
