The tube ends in a narrow channel 2 nm in width and a terminal anchor-like structure formed by two furled flaments , each with a width of 4 nm . Conversely , the total surface areas for the two types of virions are similar , about 6 103nm2. The virions carry 11 major struc tural proteins (90, 80, 70, 60, 48, 45, 38, 22, 16, 15 and 12 kDa), fve of which are modifed at their N-termini. Several of the larger proteins are rich in coiled coil and/or low complexity sequence domains. The 80 kDa protein appears to be modifed in two-tailed but not in tail-less virions. Genome organization and replication the genome encodes 72 predicted proteins and carries four putative transposable elements, which constitute 8% of the genome (Figure 2). Forty-three genes are estimated to produce leader-less tran scripts and 35 genes are organized in 12 putative operons. The host range is limited to autochthonous species of hyperthermophilic archaea from the genus Acidianus the infection leads either to viral replication and subsequent cell lysis or conversion of infected cell into a lysogene. The lysogenic cycle involves integration of the viral genome into the host chromo some, probably facilitated by a virus-encoded integrase. List of other related viruses which may be members of the genus Bicaudavirus but have not been approved as species None reported. The virions are composed of an icosahedral protein capsid and an inner protein-rich membrane enclosing the genome. Virion properties morpholoGy Icosahedral virions consist of an internal membrane and an outer protein capsid that has a diam eter of 57 nm between facets (Figure 1). The capsid consists of 200 major capsid protein P2 trimers that are organized on a pseudo T 21 lattice. The P2 trimers have pseudo-six-fold symmetry and the structure is stabilized by calcium ions. The inner membrane (47 nm in diameter) contains host plasma membrane-derived phospholipids and virus-encoded proteins P3 to P10. Transmembrane proteins P3 and P6 are organized into a lattice on the membrane vesicle sur face, on which the outer protein capsid is assembled. Virions are stable at pH 6�8, and are very sensitive to ether, chloro 20,w form and detergents. The membrane contains about 34% phosphatidyl eth anolamine and about 66% phosphatidyl glycerol and trace amounts of phosphatidic acid and acyl-phosphatidyl glycerol. The lipids are derived from the host plasma membrane, but their com position deviates from that of the host bacterium. Virions adsorb via the distal tips of the spike proteins to uncharacterized receptors. Biological properties Phages are virulent and replicate in two known strains of marine host bacteria of the genus Pseudoalteromonas. Similarity with other taxa Corticoviruses resemble tectiviruses in having a lipid bilayer underneath the isometric protein capsid. These viruses appear to differ by the genome organization and the infection mechanism, since no tectivirus-specifc tail-like membrane tube is seen upon corticoviral infection. Genus Fusellovirus Type species Sulfolobus spindle-shaped virus 1 Virion properties morpholoGy Virions are lemon-shaped, with short tail fbers attached to one pole, and slightly heterogeneous in size. Virions are 55�60 nm in their short dimension and 80�100 nm in their long dimension. The particles are stable at up to 97 �C and are insensi tive to urea, ether and pH 2. Transcripts T1 and T2 start at the same promoter and overlap, and transcripts T4, T7 and T8 similarly overlap. Eleven somewhat overlapping transcripts originating from seven pro moters have been detected and mapped. Particles appear to be assembled and are produced by extrusion at the cell membrane. Biological properties the host range of the fuselloviruses is limited to extremely thermophilic Archaea: Sulfolobus shiba tae, Sulfolobus solfataricus strains P1 and P2 and Sulfolobus islandicus strains. Fuselloviruses have been found in about 8% of Sulfolobus isolates from Icelandic solfataric felds. Phylogenetic relationships within the family Phylogenetic relationships within the family Fuselloviridae are unclear. The virus of extreme halophiles, His1, originally suggested to be a fusellovirus, on further characterization has been found to be very dissimilar and a novel genus (Salterprovirus) has been established for this group of viruses. Four newly isolated fuselloviruses from extreme geothermal environments reveal unusual mor phologies and a possible inter-viral recombination mechanism. Genus Globulovirus Type species Pyrobaculum spherical virus Virion properties morpholoGy Virions are spherical, 70�100 nm in diameter, with spherical protrusions, about 15 nm in diameter (Figure 1a). Prolonged exposure to oxygen does not affect the effciency of infection of the strictly anaerobic hosts. There are 38�48 predicted proteins encoded on viral genomes, none of which shows any sequence similarity to proteins in extant databases. Figure 1: Negative contrast electron micrographs of virions of Pyrobaculum spherical virus. The ends of the linear genome carry inverted repeat sequences (190 bp long for Pyrobaculum spherical virus), which contain multiple copies of short direct repeats. Biological properties the hosts are members of the hyperthermophilic archaeal genera Pyrobaculum and Thermoproteus. They are strict aerobes thriving in extreme geothermal environments with temperatures around 85�C, pH 6.

Particles show prominent subunits , but their precise geo metrical arrangement is not clear . Antigenic properties Some viruses in the genus are serologically related; none is related to viruses in the genus Alphacryptovirus . Virion properties morphology Virions are isometric and nonenveloped, about 31 nm in diameter as visualized by negative staining and transmission electron microscopy (Figure 7). The capsids appear single layered and thin, with short protrusions on their surfaces. Biological properties Infections of the Cryptosporidium host cells appear to be persistent and largely avirulent. Although Cryptosporidium species are pathogens of humans and other vertebrates, there are so far no well established examples in which parasite pathogenicity is either positively or negatively modulated by cryspovirus infection. Virions are disseminated in nature within Cryptosporidium oocysts, which are shed profusely from Cryptosporidium-infected animals. A correlation between cryspovirus genome levels and parasite fecundity in terms of oocyst excretion has been reported. One large cluster with strong bootstrap support includes an isolate of the type species AhV and related viruses (partitivirus I). Thus the genus Partitivirus can justifably be divided into two new genera to refect these two clusters. The remaining two RdRp clusters (Figure 8) comprise members of the genus Alphacryptovirus and probable alphacryp toviruses (see lists in the text above). The genus Alphacryptovirus can also thus justifably be divided into two new genera to refect these two clusters. No sequences have yet been reported for members of the genus Betacryptovirus, exempting them from this current analysis. The picobirnaviruses, how ever, are phylogenetically distinct and infect vertebrates rather than plant, fungi and protozoa; they probably have other basic differences including co-packaging of both genome segments and capac ity for extracellular transmission. Partitivirus structure reveals a 120-subunit, helix-rich capsid with distinctive surface arches formed by quasisymmetric coat-protein dimers. Genome organization of a partitivirus from the flamentous ascomycete Atkinsonella hypoxylon. The genome of Beet cryptic virus 1 shows high homology to certain cryptoviruses present in phylogenetically distant hosts. Genus Picobirnavirus Type species Human picobirnavirus Virion properties morpholoGy Virions are isometric, non-enveloped, 33�37 nm in diameter. The structure reveals an intricate interface with the N-terminal residues exchanged between the two subunits of the dimer. Segment 2 encodes a RdRp, whose core component contains the canonical A�B�C motif arrangement of the palm subdomain present in conventional nucleic acid polymerases. Numbers indicate the nucleotide the amino acid positions (the latter in bold type). Species demarcation criteria in the genus Only two sequences of capsid protein are yet available in databases. The capsid protein of rabbit picobirnavirus displays 25% amino acid sequence identity with its human counterpart, showing that they are phylogenetically distant. Viruses are distinguished on the basis of their host, the country in which they were identifed and the year of isolation. The picobirnavirus crystal structure provides functional insights into virion assembly and cell entry.

Metagenomic analyses of viruses in stool samples from children with acute faccid paralysis. The subfamily Spinareovirinae contains viruses that have relatively large spikes or turrets situated at the 12 icosahedral vertices of either the virus or core particle. The subfamily Sedoreovirinae includes viruses that do not have large surface projections on their virions or core particles, giving them an almost spherical or �smooth� appearance. The terminology that has been used to describe reovirus particles with different numbers of capsid layers varies among the genera. The transcriptionally active core particle of the spiked viruses (subfamily Spinareovirinae) appears to contain only a single complete capsid layer (which has been interpreted as having T 1 or T 2 symmetry), to which the projecting spikes or turrets are attached. In most cases, the core is sur rounded (in the complete virion) by an incomplete protein layer (with T 13 symmetry) that forms the outer capsid, which is penetrated by the projections on the core surface. One exception is the cypoviruses, which have transcriptionally active but fully intact virions with only a single capsid shell that are equivalent to the core particles of viruses from other genera. However, virus particles of most cypoviruses are characteristically occluded (either singly or mul tiply) within the matrix of proteinaceous crystals called polyhedra. In contrast, virions of the non-spiked viruses (subfamily Sedoreovirinae) have an inner protein layer, which may be relatively fragile, having structural similarities to the innermost shell of the spiked viruses (interpreted as having T 2 symmetry). However, in transcriptionally active core particles, the subcore is surrounded and reinforced by a complete core-surface layer, which has T 13 sym metry. These double-layered cores have no surface spikes and (in intact virions) are surrounded by Virus Taxonomy: Ninth Report of the International Committee on Taxonomy of Viruses DaneshGroup.

Twenty-three non-diving fire-fighters had stools examined for parasites; none had G . Prolonged periods of immersion are now becoming normal and activity occurs throughout the year and not just during the bathing seasons . Many gastrointestinal infections occur on a seasonal basis and therefore users will be exposed to different types of pathogens in the water . The density of users (bather-loads) at smaller recreational water bodies, especially where there is limited water turnover, may be a significant factor in the user-to-user transmission of disease. The personal hygiene of recreational water users while in the water (which may also significantly alter the quality of the water) is also a concern. In addition, certain activities that increase the likelihood of ingestion of water. Skin abrasions or cuts may contribute to recreational water-associated infections. Many environmental bacteria such as species of Pseudomonas, Aeromonas, and halophilic vibrios are opportunistic pathogens that may cause wound infections. Freshwater bathing sites may be enclosed bodies of water and fairly static, such as lakes, or running waters such as rivers. The concentration of pathogens is largely determined by faecal pollution from both point and non-point sources, although in some tropical/subtropical waters some species. Major point sources of pollution include sewage effluents, combined sewer overflows, industrial effluents and concentrated animal feeding operations. Non-point sources of pollution relate to agricultural activity and poorly functioning sanitation systems within the watershed, and are influenced by the type and density of livestock and other animals that might be present. Pathogen inputs may also exhibit seasonal variations, for example Cryptosporidium concentrations may be highest during the periods of calving or lambing (Reilly and Browning 2004). Urban surfaces also contribute significantly to the pollution load by discharging surface contaminants including animal faeces into sewers and storm drains. Faecal material is transported from the watershed surface into rivers, lakes and streams, as well as directly via sewage discharge, and subsequently to the coastal environment. The transport of microbial and other contamination is Hazard Identification and Factors Related to Infection and Disease 27 controlled by the flow of water, and changes in flow are determined by rainfall and by the hydrogeological characteristics of the basin which have a significant impact on the concentration of microbes transported. The survival of pathogenic microorganisms in water is impacted by temperature, light intensity, salinity and water quality (Johnson et al. In general, most excreta-related pathogens survive for longer periods of time in colder waters (Feachem et al. Swimming pools and spas present special conditions that may result in different exposures or favour the growth/survival of specific pathogens. Leisure pools and hot tubs may be subject to higher bather loads than naturally occurring recreational waters, increasing the likelihood of water pollution from the bathers themselves and subsequent person-to-person transmission of disease. Chlorination of pool water will generally significantly reduce the concentrations of faecally-related bacteria. Thus, waterborne outbreaks associated with exposure to chlorinated waters are much more likely to be caused by Cryptosporidium than the faecally-derived bacteria (Yoder et al. Non-faecal shedding in the water is a source of potential non-enteric pathogenic organisms. Infected users can directly contaminate the pool, hot tub or spa water and the surfaces surrounding the pool with pathogens such as viruses and fungi, which can lead to skin infections such as verrucas. Pools without water treatment may be associated with higher risk of transmission among users. Growth of certain free-living bacteria, such as Vibrio vulnificus, is favoured in warm marine water temperatures. In both coastal and freshwaters the point sources of pollution that cause most health concern are those due to domestic sewage discharges, riverine discharges and contamination from bathers. The relative risks to human health from these sources depend on a number of factors. For example, sewage being discharged into an estuary with small tidal interchanges may have a different effect to that of the same quantity of sewage being discharged into an estuary with large tidal interchanges. Areas with direct discharge of crude, untreated or inadequately treated sewage are likely to present a higher risk to public health. The content of raw or inadequately treated sewage reflects the health status of the population it 28 Water Recreation and Disease is derived from. Higher concentrations of pathogens will be present in areas where there is more disease or during disease outbreaks. This presents a special risk for people coming from low-pathogen circulation environments to high pathogen circulation environments. Information on local circumstances should be taken into account when setting guidelines to protect public health and these may vary locally or regionally. Tzipori (1988) speculated that the lower prevalence of cryptosporidiosis in older children and adults is due to immunity acquired from prior exposure. The immune status of the host seems to be the major determinant of whether the infection is self-limiting or persistent. Dysfunction of the T-lymphocytes and hypogammoglobulinaemia can both lead to persistent cryptosporidiosis (Tzipori 1988). Research has shown that persistent over-training by athletes as well as a single bout of heavy exercise can increase susceptibility to upper respiratory and other viral infections, although resistance to bacterial infections appears to be unaltered. It may be possible to infer from this research that competitive swimmers could be more at risk from contracting upper respiratory and viral infections than non-competitive recreational water users. On the other hand, certain segments of the population are especially vulnerable to acute illness (morbidity) and can exhibit high death rates.
