SSU rRNA-based phylogenetic position of the genera Amoeba and Chaos (Lobosea, Gymnamoebia): the origin of gymnamoebae revisited. (1/10)

Naked lobose amoebae (gymnamoebae) are among the most abundant group of protists present in all aquatic and terrestrial biotopes. Yet, because of lack of informative morphological characters, the origin and evolutionary history of gymnamoebae are poorly known. The first molecular studies revealed multiple origins for the amoeboid lineages and an extraordinary diversity of amoebae species. Molecular data, however, exist only for a few species of the numerous taxa belonging to this group. Here, we present the small-subunit (SSU) rDNA sequences of four species of typical large gymnamoebae: Amoeba proteus, Amoeba leningradensis, Chaos nobile, and Chaos carolinense. Sequence analysis suggests that the four species are closely related to the species of genera Saccamoeba, Leptomyxa, Rhizamoeba, Paraflabellula, Hartmannella, and Echinamoeba. All of them form a relatively well-supported clade, which corresponds to the subclass Gymnamoebia, in agreement with morphology-based taxonomy. The other gymnamoebae cluster in small groups or branch separately. Their relationships change depending on the type of analysis and the model of nucleotide substitution. All gymnamoebae branch together in Neighbor-Joining analysis with corrections for among-site rate heterogeneity and proportion of invariable sites. This clade, however, is not statistically supported by SSU rRNA gene sequences and further analysis of protein sequence data will be necessary to test the monophyly of gymnamoebae.  (+info)

Cytoskeletal organization, phylogenetic affinities and systematics in the contentious taxon Excavata (Eukaryota). (2/10)

An overview of the controversial proposal for the major eukaryote taxon "Excavata" is presented. Excavata is predicted to include at least ten distinct groups: jakobids, Malawimonas, Trimastix, Carpediemonas, retortamonads, diplomonads, Heterolobosea, oxymonads, parabasalids and Euglenozoa. These "excavates" have broadly similar flagellar apparatus organizations, for which a "universal" terminology is provided. Most, but not all, of these organisms share a distinctive suspension-feeding groove, as well as some or all of a set of seven other proposed cytoskeletal apomorphies. Cladistic analyses of morphological data do not resolve high-level relationships within Excavata. Excavate-rich molecular phylogenies recover some robust clades, but do not support or strongly refute the monophyly of Excavata. A partial classification for excavates is presented, with phylogenetic diagnoses for Excavata and for two novel taxon names, Fornicata (Carpediemonas, retortamonads, diplomonads) and Preaxostyla (Trimastix, oxymonads).  (+info)

Vertical distribution of the free-living amoeba population in soil under desert shrubs in the Negev desert, Israel. (3/10)

A field study was designed to examine the effect of desert shrubs on the dynamics of free-living amoebae in arid soil. Soil samples from 0- to 50-cm depths were collected at 10-cm intervals in each of the four seasons. The vertical distributions of the four main morphological types of amoebae, grouped according to their mobility, and of small flagellate populations were measured under the canopies of Hammada scoparia and Atriplex halimus, shrubs belonging to the chloride-absorbing xerohalophytes. The result obtained from the field study demonstrated that the total number of protozoa was significantly higher during the wet seasons (winter and spring) than during the dry seasons. The protozoan population was more diverse under the canopy of H. scoparia during the wet seasons, reaching 8,000 individuals per 1 g of dry soil, whereas during the dry seasons, the populations were higher under the canopy of A. halimus, with a mean of 250 individuals. The protozoan population in the deeper layers (40 to 50 cm) was found to be as active as that in the upper layers, demonstrating that, in the desert, soil columns below 20 cm are fertile and worth studying. The type 1 amoebae (e.g., Acanthamoeba and Filamoeba spp.) were the most abundant throughout the study period, and their numbers were significantly higher than those of the other amoeba types.  (+info)

Type IV pili and type II secretion play a limited role in Legionella pneumophila biofilm colonization and retention. (4/10)

Legionellae colonize biofilms in building water systems, yet little is known about their interaction with the organisms in these microbial communities. The role of Legionella pneumophila type IV pili and the type II secretion pre-pilin peptidase was evaluated in a model biofilm system. L. pneumophila strains 130b (wild-type), BS100 (a type IV pili mutant) and NU243 (a pre-pilin peptidase mutant) were assessed for attachment and retention in an established biofilm. Strains 130b and NU243 colonized the biofilm at a similar level while BS100 attached at a tenfold lower level. Over time, NU243 dropped below the level of detection while BS100 remained in the biofilm throughout the course of the experiment. The wild-type strain decreased but remained at a considerably higher level than either of the mutants. Inclusion of amoebae with BS100 allowed for attachment and retention at a level similar to 130b. NU243, which displays reduced intracellular replication, was able to establish itself and persist in the presence of amoebae. Thus, type IV pili and the pre-pilin peptidase facilitate L. pneumophila colonization of biofilms but are not required in the presence of a host for intracellular replication.  (+info)

Evolution of size and pattern in the social amoebas. (5/10)

A fundamental goal of biology is to understand how novel phenotypes evolved through changes in existing genes. The Dictyostelia or social amoebas represent a simple form of multicellularity, where starving cells aggregate to build fruiting structures. This review summarizes efforts to provide a framework for investigating the genetic changes that generated novel morphologies in the Dictyostelia. The foundation is a recently constructed molecular phylogeny of the Dictyostelia, which was used to examine trends in the evolution of novel forms and in the divergence of genes that shape these forms. There is a major trend towards the formation of large unbranched fruiting bodies, which is correlated with the use of cyclic AMP (cAMP) as a secreted signal to coordinate cell aggregation. The role of cAMP in aggregation arose through co-option of a pathway that originally acted to coordinate fruiting body formation. The genotypic changes that caused this innovation and the role of dynamic cAMP signaling in defining fruiting body size and pattern throughout social amoeba evolution are discussed.  (+info)

Sappinia pedata is a species of Amoebozoa. Sappinia is a free-living amoeba (a single-celled organism), found in the environment. There are two known species of Sappinia: Sappinia diploidea and Sappinia pedata. Sappinia can cause a disease similar to GAE, However only one case of GAE due to Sappinia infection has ever been reported. In 1998, a healthy 38-year-old man from Texas was found to be infected with Sappinia pedata. Although the patient was hospitalized, he survived without any long-term consequences.

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 ...

The individual animal is currently a major focus of behavioural research and an increasing number of studies raise the question of how between-individual behavioural consistency and behavioural plasticity interact. Applying the reaction norm concept on groups, our study addresses both of these aspects in one framework and within an animals natural social environment. Risk-taking behaviour in 1-year-old perch Perca fluviatilis was assayed in aquarium experiments before and after the fish were subjected to the presence or absence of a piscivorous predator for 3weeks. To analyse the inter-individual behavioural variation across the repeated measurements, we dissected the behavioural change across the predator treatment into individual constant and plastic components using hierarchical mixed-effects models. During the predator treatment, juvenile perch increased in boldness and decreased in vigilance, the magnitude of these behavioural changes was influenced by group composition. However, the ...

Excavata é um dos principais supergrupos de organismos unicelulares pertencentes ao domínio Eukaryota. Como estrutura taxonómica, o agrupamento foi proposto em 2002 por Thomas Cavalier-Smith como uma nova categoria filogenética, agregando uma grande variedade de formas simbióticas e de vida livre, entre as quais alguns importantes parasitas dos humanos. As espécies agora incluídas nos Excavata estavam anteriormente consideradas como pertencentes ao agora obsoleto reino Protista. Os Excavata são classificados com base nas características das estruturas flagelares, sendo considerados como os membros mais antigos (linhagem basal) dos organismos flagelados. O subgrupo Discoba (Euglenozoa, Percolozoa, Tsukubea e Jakobea) parecem estar entre os Eukaryota basais, enquanto os Metamonada e Malawimonas parecer constituir um grupo irmão dos Podiata. Existem algumas indicações que fazem supor que Discoba seja um grupo altamente parafilético. O agrupamento Excavata é um dos grandes grupos ...

Understanding water-related diseases. Four types of water-related diseases. There are many different kinds of pathogens, parasites, viruses and bacteria that can be found in water. The four different types of water-related diseases include:. Waterborne diseases. These are what are known as diseases that are transmitted via drinking water like cholera and typhoid.. Water-washed or water-scarce diseases. This refers to diseases that tend to spread when there is a scarcity of water. The act of washing ones hands is among the most effective means of preventing infection, but when water is scarce routine tasks such as this often get neglected. When there is less water, or less clean water, available for proper hygiene habits, such as for use in lavatories, as well as for regular washing of hands and washing of food during preparation, diseases tend to spread more easily. Water based diseases. These are diseases that infect the body via contact. This means that bathing or swimming in water ...

Honey mesquite is a single- to multi-stemmed, nitrogen-fixing, mostly deciduous, large shrub to medium-sized tree growing 1.5 to 35 feet tall. Its tiny, greenish-white to yellowish-white flowers have both male and female parts and are grouped tightly on elongated spikes that are somewhat showy, and droop. Flowering can begin on trees as early as three years of age. They are insect-, possibly wind-, and self-pollinated.. Honey mesquite grows in warm desert shrub communities and grasslands, and on plains, terraces, washes, and riparian sites, riverbanks, and bars, dry lakes, playas, hummocked dunes, mesas, and talus slopes where plants have access to permanent underground water. It is adapted to most soil types. Although it is found on hummocky sand dunes to calcareous clay, it grows best in medium- to fine-textured soils. It is a drought-tolerant plant.. ...

This class was anticipated by some biologists like Jahn, who grouped all amoebae with granular pseudopodia together,[1] but most split the lobose amoebae into testate Testacealobosia and naked Gymnamoebia. These latter are polyphyletic, but molecular trees by Bolivar et al.[2] identified a core monophyletic subgroup. Subsequent studies showed the testate lobose amoebae belong to the same group, which was thus renamed Lobosea sensu stricto[3] or Tubulinea.[4]. ...

At any one point in time, 50 percent of all people in the developing world will be in hospital suffering from one or more water-related diseases. Most will be children, water-related diseases being the second biggest killer of children worldwide (after acute respiratory diseases like Tuberculosis), according to Water Aid. (Diarrhea alone has killed more children in 10 years than all the people killed in wartime since World War 2, according to UNICEF).. The situation in the developing world will be particularly difficult moving forward, the U.N.s fourth Global Environment Outlook (GEO-4) is warning -- by 2025, it says, the developing worlds demand for water will have increased by 50 percent (the need of developed countries will have only increased by 18 percent).. Increased demand comes at a time when freshwater stocks are falling in many places. Already in western Asia, reports The Independent, freshwater stocks have fallen from 1,700 cubic meters per person per year in the 1980s to 907 today ...

The effects of 2 injected bacterins, Vibrio damsela and Pasteurella piscicida O-antigen bacterins, on the cell type composition of the peripheral blood and head kidney and on the phagocytic activity of the head kidney leucocytes were studied in turbot Scophthalmus maximus L. Blood and head kidney samples were collected from treated and non-treated turbot at different times in the 168 h period after injection. The number of neutrophils increased markedly in the peripheral blood of P. piscicida O-antigen injected turbot 24 h after injection, being significantly higher (p , 0.01) than the neutrophil number in V. damsela O-antigen injected turbot. Forty-eight hours after injection, the numbers of head kidney neutrophils and macrophages in V. damsela and in P. piscicida O-antigen injected turbot increased significantly (p , 0.05) compared with those in saline-injected turbot while the neutrophils in the peripheral blood decreased in fish treated with each of the vaccines. Turbot neutrophils have ...
MicroRNAs (miRNAs) are a group of small non-coding RNAs, which could bind to the 3′-untranslated regions of their target mRNAs to regulate gene expression in various biological processes, including immune-regulated signaling pathways. Turbot (Scophthalmus maximus L.), an important commercial fish species in China, has been suffering with Vibrio anguillarum infection resulted in dramatic economic loss. Therefore, we investigated the expression profiles of miRNAs, as well as the immune-related miRNA-mRNA pairs in turbot intestine at 1 h, 4 h, and 12 h following V. anguillarum infection. As a result, 266 predicted novel miRNAs and 283 conserved miRNAs belonging to 92 miRNA families were detected. A total of 44 miRNAs were differentially expressed in the intestine following V. anguillarum infection. Following prediction, the potential target genes of differentially expressed miRNAs were grouped into a wide range of functional categories, including immune defense/evasion, inflammatory responses, ...
Fish consumption is a potential route of human exposure to the hepatotoxic microcystins, especially in lakes and reservoirs that routinely experience significant toxic Microcystis blooms. Understanding the rates of uptake and elimination for microcystins as well as the transfer efficiency into tissues of consumers are important for determining the potential for microcystins to be transferred up the food web and for predicting potential human health impacts. The main objective of this work was to conduct laboratory experiments to investigate the kinetics of toxin accumulation in fish tissue. An oral route of exposure was employed in this study, in which juvenile yellow perch (Perca flavescens) were given a single oral dose of 5 or 20 μg of microcystin-LR (MC-LR) via food and accumulation in the muscle, liver, and tank water were measured over 24 h. Peak concentrations of the water soluble fraction of microcystin were generally observed 8-10 h after dosing in the liver and after 12-16 h in the muscle,
Study site: This research was conducted on the Sevilleta LTER, located 100 km south of Albuquerque, New Mexico, which is an ecotonal landscape of Chihuahuan desert shrub and grasslands (Muldavin et al. 2008). Data were collected from a 0.9 x 0.5km strip of land that encompassed a flat bajada and a shallow rocky canyon of mixed desert shrub and grassland dominated by the creosote bush (Larrea tridentata) and black grama grass (Bouteloua eriopoda). Tissue collection & sample preparation for stable isotope analysis:. From May to October of 2005 and 2006 we collected plant, lizard, and arthropod tissues for carbon stable isotope analysis. During mid-summer of 2005, we randomly collected leaf and stem samples from the 38 most abundant species of plants; these species produce over 90% of the annual biomass on our study site (see Appendix Table A). Approximately 3.5 mg of plant material was then loaded into pre-cleaned tin capsules for isotope analysis. All animal research was conducted with the ...
To study the effect of morphometric attributes on body weight of the turbot Scophthalmus maximus,morphometric measurement was taken on 1120 3-month-old turbots sampled in a local company in Yantai,Shandong of China.The attributes used in this study include body length,total length,body depth,head length,length between snout tip and frontal of gill cleft,tail handle length,tail handle height,body width,and body weight.A correlation coefficient matrix was constructed,in which the body weight was used as the dependent variable and other attributes as independent variables for path analysis.The path coefficients(P_i),determination coefficients(d_i and d_ ij),and correlation index(R2) were calculated,and major morphometric attributes determined.The results showed that all the correlation coefficient between each independent variable and dependent variable(body weight) were significantly different(P0.01).The total length gave a predominant direct effect(0.720) and determinacy on the body weight,it is the key

Larval parasites within paratenic hosts rarely grow; likewise larval stages in intermediate hosts frequently stop growing before their growth is compromised by limited host resources and enter a stage of growth arrest. At this stage, the parasite may become encapsulated, which as an evolved strategy can reduce their mortality rate [43]. Encapsulation, however, is mutual adaptation between the hosts immune response and parasite, reaching a strategic compromise between the two to ensure the survival of both species [19]. The various life strategies employed by parasite species can influence different aspects of host physiology and so activate different immunological pathways [44]. The manner in which mammalian muscle responds to encapsulating species of nematode like Trichinella spiralis (Owen, 1835), for example, which elicits an inflammatory reaction, is different to that of non-encapsulating species of nematode like Trichinella pseudospiralis Garkavi, 1972, [19]. During infection with T. ...

Recently developed theoretical models of stage-structured consumer-resource systems have shown that stage-specific biomass overcompensation can arise in response to increased mortality rates. We parameterized a stage-structured population model to simulate the effects of increased adult mortality caused by a pathogen outbreak in the perch (Perca fluviatilis) population of Windermere (UK) in 1976. The model predicts biomass overcompensation by juveniles in response to increased adult mortality due to a shift in food-dependent growth and reproduction rates. Considering cannibalism between life stages in the model reinforces this compensatory response due to the release from predation on juveniles at high mortality rates. These model predictions are matched by our analysis of a 60- year time series of scientific monitoring of Windermere perch, which shows that the pathogen outbreak induced a strong decrease in adult biomass and a corresponding increase in juvenile biomass. Age-specific adult ...
Saprolegnia parasitica Coker is the main agent of saprolegniosis, one of the most important causes of economic losses in the fish farming industry, affecting all developmental stages. In this work the activity of some essential oils are compared with the activity of their isolated chemical constituents (alcohols, aldehydes, ketones, phenols, and hydrocarbons) to evaluate molecular classes active against S. parasitica. This suggests potential new products to use against saprolegniosis. Sixteen commercial essential oils and 37 pure constituents were tested against a strain of Saprolegnia parasitica from cutaneous lesions of Perca fluviatilis Linnaeus, using a continuously agitated broth technique that allows both the Minimum Inhibitory Concentration (MIC) and the Minimum Lethal Concentration (MLC) to be evaluated. It was possible to evaluate the efficacy of each essential oil against S. parasitica in relation to its specific composition and the efficacy of its main constituents. Carvacrol (MIC of ...
The Trout-perch Percopsis omiscomaycus (Walbaum) is a widely distributed species in North America, yet they present a number of puzzles. Percopsis means "perch like" (Greek, perke=perch and opsis=appearance) and omiscomaycus is an Algonkian name that includes the root word "trout." This enigmatic fish is certainly not a trout - though it has an adipose fin and a scaleless head -- and certainly not a perch - though its coloration and spines are somewhat similar. It has traits that are characteristic of each group. For example, the dorsal fin has 2 weak spines and pelvic and anal fins each have one weak spine. And the scales are ctenoid with a single row of teeth on the edge. But, there is that puzzling adipose fin. The head is large and the premaxillary bones are nonprotractile, unlike the Yellow Perch Perca flavescens. Trout-perch are ray-finned fish in the Class Actinopterygii (ACK-tih-NOP-tuh-RIJ-ee-eye). They are a surviving remnant of mostly marine fish that marked the transition between ...
TY - JOUR. T1 - Evolution of size and pattern in the social amoebas. AU - Schaap,P.. N1 - MEDLINE® is the source for the MeSH terms of this document.. PY - 2007/7. Y1 - 2007/7. N2 - A fundamental goal of biology is to understand how novel phenotypes evolved through changes in existing genes. The Dictyostelia or social amoebas represent a simple form of multicellularity, where starving cells aggregate to build fruiting structures. This review summarizes efforts to provide a framework for investigating the genetic changes that generated novel morphologies in the Dictyostelia. The foundation is a recently constructed molecular phylogeny of the Dictyostelia, which was used to examine trends in the evolution of novel forms and in the divergence of genes that shape these forms. There is a major trend towards the formation of large unbranched fruiting bodies, which is correlated with the use of cyclic AMP (cAMP) as a secreted signal to coordinate cell aggregation. The role of cAMP in aggregation arose ...
Schoth M.; Tesch F W., 1984: The vertical distribution of small o group anguilla larvae in the sargasso sea with reference to other anguilliform leptocephali
In early 2011, a joint initiative was started under the auspices of SPARC, the International Ozone Commission (IO3C), the ozone focus area of the Integrated Global Atmospheric Chemistry Observations (IGACO-O3) programme, and the Network for Detection of Atmospheric Composition Change (NDACC). To aid digestion, an acronym of acronyms, SI2N, was adopted. Reports on the two workshops were published in SPARC Newsletters 37 and 39 (Harris et al., 2011, 2012 - http://www.sparc-climate.org/publications/).The main objective of SI2N is to assess and extend the current knowledge and understanding of measurements of the vertical distribution of ozone, with the aim of providing input to the next WMO/UNEP Scientific Assessment of Ozone Depletion anticipated for 2014. It is effectively a follow-up of the SPARC/IOC/GAW Ozone Profile Assessment (http://www.sparc-climate.org/publications/ ...
Abstract. Aerosol-planetary boundary layer (PBL) interaction was proposed as an important mechanism to stabilize atmosphere and exacerbate surface air pollution. Despite the tremendous progress made in understanding this process, its magnitude and significance still bear large uncertainties and vary largely with aerosol distribution and meteorological conditions. In this study, we particularly focus on the role of aerosol vertical distribution on thermodynamic stability and PBL development by jointly using the micropulse lidar, sun-photometer, and radiosonde measurements over Beijing. Despite complex aerosol vertical distributions, the cloud-free aerosol structures can be classified into three types: well-mixed, decreasing with height, and the inversed. Under these different aerosol vertical structures, the aerosol-PBL relationships and the diurnal cycles of the PBLH and PM2.5 show distinct characters. The vertical distribution of aerosol radiative forcing differs drastically with strong heating ...

en] The current study aimed to evaluate the influence of domestication process on the stress response and subsequent immune modulation in Eurasian perch juveniles (Perca fluviatilis) submitted to chronic confinement. Briefly, F1 and F4 generations were confined into small-size tanks and sampled 7 and 55 days after stocking. Cortisol and glucose levels as well as lysozyme activity and immunoglobulin level were evaluated in the serum. Spleen Somatic Index and spleen ROS production were also measured. A proteomic analysis was performed on serum sampled on day 7. Finally, both generations were genetically characterized using a microsatellite approach. Globally, results revealed that chronic confinement did not elicit a typical stress response but resulted in a prolonged immune stimulation. Proteomic results suggested that domestication process influenced the immune status of perch submitted to chronic confinement as the F1 confined fish displayed lower abundance of C3 complement component, ...

For many countries, fresh water availability is an acute concern. In some cases it is the sheer number of people in one location that is triggering the deficiency, in others it is rising sea levels due to climate change, and in some situations it is a particular industry (such as cotton) that is causing the problem. Because of this, over 1 billion people have no access to clean drinking water and 2 million people die annually from water-related diseases. Most of these grave concerns are . . .

Clausena excavata (Lour.), locally known as "Kemantu hitam," is a common plant in Malaysian folklore medicine. This study evaluated the antioxidant properties of the solvent extracts of C. excavata leaves and determined the acute toxicity of methanolic extract C. excavata (MECE) leaves in Sprague-Dawley rats. Harvested leaves were dried and subjected to solvent extraction using petroleum ether, chloroform, ethyl acetate and methanol in succession. The antioxidant activity of each extract was determined using the ferric-reducing antioxidant power (FRAP) and 2,2-diphenyl-1-picryl dihydrazyl (DPPH) radical scavenging activity. The total phenolic content (TPC) and total flavonoids content (TFC) were estimated by Folin-Ciocalteu and ethanolic aluminium chloride method, respectively. The chloroform extract was found to be highest in flavonoid content, while the methanolic extract showed the highest TPC and antioxidant activity. There was no mortality in rats treated with MECE leaves even at a high ...

Systemic ciliatosis caused by histophagous ciliates constitutes a serious disease of cultured turbot. Six ciliate isolates were obtained from parasitized turbot during six epizootics at four different farms located in Spain, France and Portugal. Axenic cultures of the six isolates were obtained by periodical subculturing in ATCC 1651MA or supplemented L-15 media. In basal media or seawater, the parasites could survive starving for long periods with no apparent proliferation. In adequate media, growth kinetics was found to be very similar for isolates A and B, with a clear influence of temperature. Morphological studies demonstrated that all isolates share common features that allows their assignment to either Philasterides Kahl, 1931 or Miamiensis Thompson et Moewus, 1964. However, statistically significant differences were evident in pairwise comparisons of the isolates from the four farm sites in 16 taxonomically relevant morphometric features. This could allow the discrimination of different ...
Dictyostelid social amoebae are a large and ancient group of soil microbes with an unusual multicellular stage in their life cycle. Taxonomically, they belong to the eukaryotic supergroup Amoebozoa, the sister group to Opisthokonta (animals + fungi). Roughly half of the similar to 150 known dictyostelid species were discovered during the last five years and probably many more remain to be found. The traditional classification system of Dictyostelia was completely overturned by cladistic analyses and molecular phylogenies of the past six years. As a result, it now appears that, instead of three major divisions there are eight, none of which correspond to traditional higher-level taxa. In addition to the widely studied Dictyostelium discoideum, there are now efforts to develop model organisms and complete genome sequences for each major group. Thus Dictyostelia is becoming an excellent model for both practical, medically related research and for studying basic principles in cell-cell communication ...

ABSTRACT: Cryptosporidium scophthalmi n. sp. is described from the turbot Scophthalmus maximus L., sampled from different farms on the coast of NW Spain. The parasite was found mainly in the intestinal epithelium and very seldom in the stomach. Oocysts were almost spherical, with 4 naked sporozoites and a residuum, and measured 3.7 5.03 × 3.03 4.69 µm (mean 4.44 × 3.91) (shape index 1.05 1.34, mean 1.14). Sporulation was endogenous, as fully sporulated oocysts were found within the intestinal epithelium, lumen and faeces. Merogonial and gamogonial stages were in the typical extracytoplasmic position, whereas sporogonial stages were deep within the epithelium. Oocysts and other stages of C. scophthalmi comply with most of the diagnostic features of the genus Cryptosporidium, but differ from all hitherto described species. Ultrastructural features, including the characteristic feeding organelle, were mainly comparable with those of other Cryptosporidium species. Mitochondria were frequently ...
Ozonation has proven useful in recirculating aquaculture systems promoting the stabilization of water quality and disease control. Nevertheless, its cytogenetic and physiological effects on fish are still largely unknown. Hence, this research investigated the effects of ozone exposure in juvenile turbot (Scophthalmus maximus) by assessing its genotoxic potential (erythrocytic nuclear abnormalities - ENA - assay) and alterations on hematological parameters (hemoglobin concentration - Hb, red blood cell - RBC - count, mean cell hemoglobin - MCH). Fish were subjected to a daily 6-h ozone (0.15 mg L− 1) exposure, repeated for 3 consecutive days. In order to assess the potential recovery after ozone treatment, fish were also analyzed on 1-day (R1) and 7-day (R7) post-treatment. An ENA induction was recurrently detected along the exposure period, suggesting genetic damage. Moreover, this clastogenic effect was prolonged beyond the exposure period up to day R7. The Hb concentration increased on days ...
Water-related impacts due to change in climatic conditions ranging from water scarcity to intense floods and storms are increasing in developing countries like Pakistan. Water quality and waterborne diseases like hepatitis, cholera, typhoid, malaria and dengue fever are increasing due to chaotic urbanization, industrialization, poor hygienic conditions, and inappropriate water management. The morbidity rate is high due to lack of health care facilities, especially in developing countries. Organizations linked to the Government of Pakistan (e.g., Ministry of Environment, Ministry of Climate Change, Planning and Development, Ministry of Forest, Irrigation and Public Health, Pakistan Meteorological Department, National Disaster Management, Pakistan Agricultural Research Centre, Pakistan Council for Research in Water Resources, and Global Change Impact Study Centre), United Nation organizations, provincial government departments, non-governmental organizations (e.g., Global Facility and Disaster Reduction),
Os loucozoos (Loukozoa) (do grego loukos, suco ) é um táxon parafilético de protistas utilizado nalgumas classificações dos Excavata. O grupo foi proposto por Thomas Cavalier-Smith e foi varias vezes corrigido para incluir novos géneros. O grupo principal dos Loukozoa são os Jakobida (Jakobea). Os Loukozoa incluem também Malawimonas. Ainda que os Jakobea e Malawimonas pareçam bastante semelhantes, não estão especificamente relacionados entre si dentro do grupo dos Excavata, pelo que os Loukozoa são um grupo parafilético. Além disso, as evidências filogenéticas moleculares indicam claramente que, na realidade, os Jakobea estão mais relacionados com Heterolobosea e Euglenozoa.. Por este motivo, o uso do grupo Leukozoa foi abandonado na maioria das classificações modernas. Cavalier-Smith, T. (1999).
