Chlamydiaceae: A family of gram-negative, coccoid microorganisms, in the order CHLAMYDIALES, pathogenic for vertebrates. Genera include CHLAMYDIA and CHLAMYDOPHILA.Chlamydiaceae Infections: Infections with bacteria of the family CHLAMYDIACEAE.Chlamydiales: An order of obligately intracellular, gram-negative bacteria that have the chlamydia-like developmental cycle of replication. This is a two-stage cycle that includes a metabolically inactive infectious form, and a vegetative form that replicates by binary fission. Members of Chlamydiales are disseminated by aerosol or by contact. There are at least six recognized families: CHLAMYDIACEAE, Criblamydiaceae, Parachlamydiaceae, Rhabdochlamydia, Simkaniaceae, and Waddliaceae.Chlamydia: A genus of the family CHLAMYDIACEAE whose species cause a variety of diseases in vertebrates including humans, mice, and swine. Chlamydia species are gram-negative and produce glycogen.

The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.Ligase Chain Reaction: A DNA amplification technique based upon the ligation of OLIGONUCLEOTIDE PROBES. The probes are designed to exactly match two adjacent sequences of a specific target DNA. The chain reaction is repeated in three steps in the presence of excess probe: (1) heat denaturation of double-stranded DNA, (2) annealing of probes to target DNA, and (3) joining of the probes by thermostable DNA ligase. After the reaction is repeated for 20-30 cycles the production of ligated probe is measured.Gene Amplification: A selective increase in the number of copies of a gene coding for a specific protein without a proportional increase in other genes. It occurs naturally via the excision of a copy of the repeating sequence from the chromosome and its extrachromosomal replication in a plasmid, or via the production of an RNA transcript of the entire repeating sequence of ribosomal RNA followed by the reverse transcription of the molecule to produce an additional copy of the original DNA sequence. Laboratory techniques have been introduced for inducing disproportional replication by unequal crossing over, uptake of DNA from lysed cells, or generation of extrachromosomal sequences from rolling circle replication.Patents as Topic: Exclusive legal rights or privileges applied to inventions, plants, etc.Veterinary Medicine: The medical science concerned with the prevention, diagnosis, and treatment of diseases in animals.Orchitis: Inflammation of a TESTIS.

Molecular evidence for the existence of additional members of the order Chlamydiales. (1/47)

Respiratory tract infections in man may be caused by several members of the genus Chlamydia and also by two Chlamydia-like strains, 'Simkania negevensis' (Z-agent) and 'Parachlamydia acanthamoebae' (Bng). To facilitate diagnostic procedures a PCR assay able to detect all known Chlamydiaceae sequences in one reaction was developed. For this purpose, primers were selected to amplify a fragment of the 16S rRNA gene. Characterization of the amplified fragments was done by hybridization with specific probes and by sequencing. PCR assays were carried out using DNA isolated from nose/throat specimens or from peripheral blood mononuclear cells of patients with respiratory tract infections, and from vessel wall specimens of abdominal aneurysms. Six of the 42 nose/throat swab specimens analysed yielded strong bands and one yielded a faint band. Three of these bands were identified as Chlamydia pneumoniae and one as Chlamydia trachomatis by sequencing. Analysis of the three other bands yielded two different new sequences. DNA isolated from peripheral blood mononuclear cells of one patient yielded a third new sequence. DNA isolated from peripheral blood mononuclear cells of four healthy controls was negative. One of the abdominal aneurysm specimens also yielded a strong band. Sequencing revealed a fourth new sequence. All negative controls included during specimen processing and PCR analysis remained negative. The typical secondary structure of microbial 16S genes was present in all four new sequences indicating the validity of the sequence data. All four new sequences were distinct from other bacteria and clustered together with known Chlamydiaceae sequences. Phylogenetic analysis suggested a new lineage, separating the four new sequences, 'S. negevensis' and 'P. acanthamoebae' from the genus Chlamydia with the four known chlamydial species. In conclusion, this study provides evidence for the existence of several new members of the order Chlamydiales. Since the source of the Chlamydia-like strains has not been identified and serological and/or molecular cross-reactivities may be expected, results of identification of infecting recognized organisms should be interpreted cautiously.  (+info)

Emended description of the order Chlamydiales, proposal of Parachlamydiaceae fam. nov. and Simkaniaceae fam. nov., each containing one monotypic genus, revised taxonomy of the family Chlamydiaceae, including a new genus and five new species, and standards for the identification of organisms. (2/47)

The current taxonomic classification of Chlamydia is based on limited phenotypic, morphologic and genetic criteria. This classification does not take into account recent analysis of the ribosomal operon or recently identified obligately intracellular organisms that have a chlamydia-like developmental cycle of replication. Neither does it provide a systematic rationale for identifying new strains. In this study, phylogenetic analyses of the 16S and 23S rRNA genes are presented with corroborating genetic and phenotypic information to show that the order Chlamydiales contains at least four distinct groups at the family level and that within the Chlamydiaceae are two distinct lineages which branch into nine separate clusters. In this report a reclassification of the order Chlamydiales and its current taxa is proposed. This proposal retains currently known strains with > 90% 16S rRNA identity in the family Chlamydiaceae and separates other chlamydia-like organisms that have 80-90% 16S rRNA relatedness to the Chlamydiaceae into new families. Chlamydiae that were previously described as 'Candidatus Parachlamydia acanthamoebae' Amann, Springer, Schonhuber, Ludwig, Schmid, Muller and Michel 1997, become members of Parachlamydiaceae fam. nov., Parachlamydia acanthamoebae gen. nov., sp. now. 'Simkania' strain Z becomes the founding member of Simkaniaceae fam. nov., Simkania negevensis gen. nov., sp. nov. The fourth group, which includes strain WSU 86-1044, was left unnamed. The Chlamydiaceae, which currently has only the genus Chlamydia, is divided into two genera, Chlamydia and Chlamydophila gen. nov. Two new species, Chlamydia muridarum sp. nov. and Chlamydia suis sp. nov., join Chlamydia trachomatis in the emended genus Chlamydia. Chlamydophila gen. nov. assimilates the current species, Chlamydia pecorum, Chlamydia pneumoniae and Chlamydia psittaci, to form Chlamydophila pecorum comb. nov., Chlamydophila pneumoniae comb. nov. and Chlamydophila psittaci comb. nov. Three new Chlamydophila species are derived from Chlamydia psittaci: Chlamydophila abortus gen. nov., sp. nov., Chlamydophila caviae gen. nov., sp. nov. and Chlamydophila felis gen. nov., sp. nov. Emended descriptions for the order Chlamydiales and for the family Chlamydiaceae are provided. These families, genera and species are readily distinguished by analysis of signature sequences in the 16S and 23S ribosomal genes.  (+info)

Identification of nine species of the Chlamydiaceae using PCR-RFLP. (3/47)

The family Chlamydiaceae contains two genera and nine species. Rapid and easy identification of these species is essential for taxonomic, epidemiological and clinical determinations. Currently, DNA sequence analysis is the only accepted method that decisively distinguishes all nine species. In this study, a simple and rapid PCR-RFLP procedure was developed by which laboratory-cultured chlamydial specimens could be identified. To accomplish this, conserved oligonucleotide primers and restriction sites were deduced from 16S and 23S rRNA sequence data from > 50 chlamydial strains representing all nine species. DNA from 25 previously characterized chlamydial strains were tested with these primers and restriction enzymes. All nine chlamydial species were reliably distinguished in the tests. The procedure was optimized by adjusting the annealing temperature using both a standard and a heat-activated DNA polymerase to reduce mismatch PCR amplification of mycoplasmas and other bacteria. The result was that a PCR method for species identification of chlamydial isolates and for distinguishing mycoplasmas and chlamydiae was created. This method can be used to rapidly identify known species of the family Chlamydiaceae.  (+info)

Simkania negevensis strain ZT: growth, antigenic and genome characteristics. (4/47)

Simkania negevensis is the type species of Simkaniaceae, a recently proposed family in the order Chlamydiales. In the current study, growth, antigenic and genomic characteristics of this intracellular bacterium were investigated and compared to those of members of the family Chlamydiaceae. Growth of the organism, as assessed by infectivity assays, reached a plateau in 2-3 d although by light microscopy the cytopathic effect on the host cells increased for 12 or more days after infection. S. negevensis growth was unaffected by sulfadiazine. Cells infected by S. negevensis strain ZT were not recognized by either of two monoclonal antibodies specific for Chlamydiaceae LPS and several specific Chlamydiaceae ompA primers were unable to PCR amplify a S. negevensis gene. The S. negevensis genome contained one copy of the ribosomal operon. The genome size of S. negevensis strain ZT was determined by PFGE to be 1.7 Mbp, and the G + C content was 42.5 mol%. These data, taken together with other published data, are consistent with the proposal that S. negevensis belongs to a distinct family in the order Chlamydiales.  (+info)

'Candidatus Xenohaliotis californiensis', a newly described pathogen of abalone, Haliotis spp., along the west coast of North America. (5/47)

Withering syndrome is a fatal disease of wild and cultured abalone, Haliotis spp., that inhabit the west coast of North America. The aetiological agent of withering syndrome has recently been identified as a member of the family Rickettsiaceae in the order Rickettsiales. Using a combination of morphological, serological, life history and genomic (16S rDNA) characterization, we have identified this bacterium as a unique taxon and propose the provisional status of 'Candidatus Xenohaliotis californiensis'. The Gram-negative, obligate intracellular pleomorphic bacterium is found within membrane-bound vacuoles in the cytoplasm of abalone gastrointestinal epithelial cells. The bacterium is not cultivable on synthetic media or in fish cell lines (e.g. CHSE-214) and may be controlled by tetracyclines (oxytetracycline) but not by chloramphenicol, clarithromycin or sarafloxicin. Phylogenetic analysis based on the 16S rDNA of 'Candidatus Xenohaliotis californiensis' places it in the alpha-subclass of the class Proteobacteria but not to the four recognized subtaxa of the alpha-Proteobacteria (alpha-1, alpha-2, alpha-3 and alpha-4). The bacterium can be detected in tissue squashes stained with propidium iodide, microscopic examination of stained tissue sections, PCR or in situ hybridization. 'Candidatus Xenohaliotis californiensis' can be differentiated from other closely related alpha-Proteobacteria by its unique 16S rDNA sequence.  (+info)

Chlamydophila abortus in a Brown skua (Catharacta antarctica lonnbergi) from a subantarctic island. (6/47)

On Bird Island, South Georgia, a new strain of Chlamydophila abortus was detected in one Brown skua out of 37 specimens from six different seabird species. Phylogenetic analysis of the rnpB and omp1 genes indicated the strain to be more closely related to C. abortus than to 6BC, the type strain of Chlamydophila psittaci.  (+info)

Comparative analyses of secondary gene products of 3-deoxy-D-manno-oct-2-ulosonic acid transferases from Chlamydiaceae in Escherichia coli K-12. (7/47)

The waaA gene encoding the essential, lipopolysaccharide (LPS)-specific 3-deoxy-Dmanno-oct-2-ulosonic acid (Kdo) transferase was inactivated in the chromosome of a heptosyltransferase I and II deficient Escherichia coli K-12 strain by insertion of gene expression cassettes encoding the waaA genes of Chlamydia trachomatis, Chlamydophila pneumoniae or Chlamydophila psittaci. The three chlamydial Kdo transferases were able to complement the knockout mutation without changing the growth or multiplication behaviour. The LPS of the mutants were serologically and structurally characterized in comparison to the LPS of the parent strain using compositional analyses, high performance anion exchange chromatography, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry and specific monoclonal antibodies. The data show that chlamydial Kdo transferases can replace in E. coli K-12 the host's Kdo transferase and retain the product specificities described in their natural background. In addition, we unequivocally proved that WaaA from C. psittaci transfers predominantly four Kdo residues to lipid A, forming a branched tetrasaccharide with the structure alpha-Kdo-(2-->8)-[alpha-Kdo-(2-->4)]-alpha-Kdo-(2-->4)-alpha-Kdo.  (+info)

Molecular evolution of the Chlamydiaceae. (8/47)

Phylogenetic analyses of surface antigens and other chlamydial proteins were used to reconstruct the evolution of the Chlamydiaceae. Trees for all five coding genes [the major outer-membrane protein (MOMP), GroEL chaperonin, KDO-transferase, small cysteine-rich lipoprotein and 60 kDa cysteine-rich protein] supported the current organization of the family Chlamydiaceae, which is based on ribosomal, biochemical, serological, ecological and DNA-DNA hybridization data. Genetic distances between some species were quite large, so phylogenies were evaluated for robustness by comparing analyses of both nucleotide and protein sequences using a variety of algorithms (neighbour-joining, maximum-likelihood, maximum-parsimony with bootstrapping, and quartet puzzling). Saturation plots identified areas of the trees in which factors other than relatedness may have determined branch attachments. All nine species were clearly differentiated by distinctness ratios calculated for each gene. The distribution of virulence traits such as host and tissue tropism were mapped onto the consensus phylogeny. Closely related species were no more likely to share virulence characters than were more distantly related species. This phylogenetically disjunct distribution of virulence traits could not be explained by lateral transfer of the genes we studied, since we found no evidence for lateral gene transfer above the species level. One interpretation of this observation is that when chlamydiae gain access to a new niche, such as a new host or tissue, significant adaptation ensues and the virulence phenotype of the new species reflects adaptation to its environment more strongly than it reflects its ancestry.  (+info)

Trachoma is the leading cause of preventable blindness. Commercial assays do not discriminate among all Chlamydiaceae species that might be involved in trachoma. We investigated whether a commercial Micro-ArrayTube could discriminate Chlamydiaceae species in DNA extracted directly from conjunctival samples from 101 trachoma patients in Nepal. To evaluate organism viability, we extracted RNA, reverse transcribed it, and subjected it to quantitative real-time PCR. We found that 71 (70.3%) villagers were infected. ArrayTube sensitivity was 91.7% and specificity was 100% compared with that of real-time PCR. Concordance between genotypes detected by microarray and ompA genotyping was 100%. Species distribution included 54 (76%) single infections with Chlamydia trachomatis, C. psittaci, C. suis, or C. pecorum, and 17 (24%) mixed infections that includied C. pneumoniae. Ocular infections were caused by 5 Chlamydiaceae species. Additional studies of trachoma pathogenesis involving Chlamydiaceae species other
The Chlamydiaceae are a family of bacteria that belongs to the phylum Chlamydiae, order Chlamydiales. All Chlamydiaceae species are Gram-negative and express the family-specific lipopolysaccharide epitope αKdo-(2→8)-αKdo-(2→4)-αKdo (previously called the genus-specific epitope). Chlamydiaceae ribosomal RNA genes all have at least 90% DNA sequence identity. Chlamydiaceae species have varying inclusion morphology, varying extrachromosomal plasmid content, and varying sulfadiazine resistance. The Chlamydiaceae family currently includes two genera and one candidate genus: Chlamydia, Chlamydophila, and candidatus Clavochlamydia. Three species belong to Chlamydia: C. trachomatis, C. muridarum, and C. suis. C. trachomatis has been found only in humans, C. muridarum in hamsters and mice (family Muridae), and C. suis in swine. Chlamydia species produce a small amount of detectable glycogen and have two ribosomal operons. C. trachomatis is the cause of an infection commonly transmitted sexually ...

Recent taxonomic analysis using the 16S and 23S rRNA genes have found that the order Chlamydiales contains at least four distinct groups at the family level and that within the order Chlamydiaceae are two distinct lineages. Chlamydiae also share a group-specific lipopolysaccharide (LPS) antigen and utilize host adenosine triphosphate for the synthesis of chlamydial protein. Beatty and coworkers demonstrated that the addition of 0.2 ng/ml of IFN-γ inhibited intracellular growth of Chlamydia trachomatis in HeLa cells by induction of the indoleamine 2,3- dioxygenase, leading to a persistent state. The development of large aberrant reticulate body (RB) forms combined with the absence of elementary bodies (EBs) was characteristic of persistent C. trachomatis infection. C. pneumoniae is a common human respiratory pathogen, affecting all ages with a worldwide distribution. While C. pneumoniae appears to be clearly associated with asthma exacerbations, it has also been hypothesized to have a role in asthma

Chlamydiaceae are Gram-negative obligate intracellular bacteria. They are responsible for a broad range of diseases in animals and humans. In pigs, Chlamydia suis, Chlamydia abortus, Chlamydia pecorum and Chlamydia psittaci have been isolated. Chlamydiaceae infections in pigs are associated with different pathologies such as conjunctivitis, pneumonia, pericarditis, polyarthritis, polyserositis, pseudo-membranous or necrotizing enteritis, periparturient dysgalactiae syndrome, vaginal discharge, return to oestrus, abortion, mummification, delivery of weak piglets, increased perinatal and neonatal mortality and inferior semen quality, orchitis, epididymitis and urethritis in boars. However, Chlamydiaceae are still considered as non-important pathogens because reports of porcine chlamydiosis are rare. Furthermore, Chlamydiaceae infections are often unnoticed because tests for Chlamydiaceae are not routinely performed in all veterinary diagnostic laboratories and Chlamydiaceae are often found in association

Chlamydiae is a unique bacterial evolutionary group that separated from other bacteria approximately a billion years ago.[9][10] The species from this group can be distinguished from all other bacteria by the presence of conserved indels in a number of proteins such as RNA polymerase alpha subunit, Gyrase B, Elongation factor-Tu and Elongation factor-P, and by large numbers of signature proteins that are uniquely present in different chlamydiae species.[11][12] Reports have varied as to whether Chlamydiae is related to Planctomycetales or Spirochaetes.[13][14] Genome sequencing, however, indicates that 11% of the genes in Candidatus Protochlamydia amoebophila UWE25 and 4% in Chlamydiaceae are most similar to chloroplast, plant, and cyanobacterial genes.[10] However, phylogeny and shared presence of conserved indels in proteins such as RNA polymerase Beta subunit and lysyl-tRNA synthetase indicate that Verrucomicrobia are the closest free-living relatives of these parasitic organisms.[15] ...
The phosphoenolpyruvate (PEP)-dependent phosphotransferase system (PTS) is a major mechanism used by bacteria for uptake of carbohydrates, particularly hexoses, hexitols, and disaccharides, where the source of energy is from PEP. The PTS consists of two general components, enzyme I (EI) and histidine phosphocarrier protein (HPr), and of membrane-bound sugar specific permeases (enzymes II). Each enzyme II (EII) complex consists of one or two hydrophobic integral membrane domains (domains C and D) and two hydrophilic domains (domains A and B). EII complexes may exist as distinct proteins or as a single multidomain protein. The PTS catalyzes the uptake of carbohydrates and their conversion into their respective phosphoesters during transport. There are four successive phosphoryl transfers in the PTS. Initial autophosphorylation of EI, using PEP as a substrate, is followed by transfer of the phosphoryl group from EI to HPr. EIIA catalyzes the self-phosphoryl transfer from HPr after which the ...

The order Chlamydiales contains at least four distinct family groups: Chlamydiaceae, Simkaniaceae, Waddliaceae and Parachlamydiaceae. Within the family Chlamydiaceae there are two distinct genera: Chlamydia and Chlamydophila. The Chlamydophila genus has seven recognised species, namely Chlamydophila pecorum, Chlamydophila pneumoniae, Chlamydophila psittaci, Chlamydophila abortus, Chlamydophila caviae (formerly Chlamydophila psittaci guinea pig conjunctivitis strain) and Chlamydophila felis[1, 2].. A unique developmental cycle distinguishes Chlamydophila from other intracellular bacteria [3]. The infectious elementary body (EB) and the vegetative reticulate body (RB) are two major developmental forms involved in the cycle. One of the predominant proteins found on the surface of both the EB and RB forms is the major outer membrane protein (MOMP, OmpA). MOMP makes up 60% of the total outer membrane protein [4], and published data have indicated that it is critical for chlamydial infection ...

Chlamydia psittaci is an obligate intracellular bacterium that can cause significant disease among a broad range of hosts. In humans, this organism may cause psittacosis, a respiratory disease that can spread to involve multiple organs, and in rare untreated cases may be fatal. There are ten known genotypes based on sequencing the major outer-membrane protein gene, ompA, of C. psittaci. Each genotype has overlapping host preferences and virulence characteristics. Recent studies have compared C. psittaci among other members of the Chlamydiaceae family and showed that this species frequently switches hosts and has undergone multiple genomic rearrangements. In this study, we sequenced five genomes of C. psittaci strains representing four genotypes, A, B, D and E. Due to the known association of the type III secretion system (T3SS) and polymorphic outer-membrane proteins (Pmps) with host tropism and virulence potential, we performed a comparative analysis of these elements among these five strains ...

Background: Tests available for molecular diagnosis of chlamydial infections detect Chlamydiatrachomatis, but do not find other Chlamydia species associated with genital, ophthalmic, cardiovascular, respiratory or neurological diseases. The routine detection of all Chlamydia species would improve the prognosis of infected people and guide therapeutic choices.. Aim: To design and validate a sensitive, specific, reproducible, inexpensive and easy-to-perform assay to quantify most Chlamydia species.. Methods: Primers and probe were selected using the gene coding for the 16S rRNA. The detection limits were assessed for suspensions of Chlamydia trachomatis, Chlamydia psittaci and Chlamydia pneumoniae. The performance of this test was compared with that of two commercial kits (Amplicor-Roche and Artus) on 100 samples obtained from children with trachoma.. Results: The detection capacities for Chlamydia trachomatis of the broad-range real-time polymerase chain reaction (PCR) were similar or slightly ...

Species of Chlamydia are the etiologic agent of endemic blinding trachoma, the leading cause of bacterial sexually transmitted diseases, significant respiratory pathogens, and a zoonotic threat. Their dependence on an intracellular growth niche and their peculiar developmental cycle are major challenges to elucidating their biology and virulence traits. The last decade has seen tremendous advances in our ability to perform a molecular genetic analysis of Chlamydia species. Major achievements include the generation of large collections of mutant strains, now available for forward- and reverse-genetic applications, and the introduction of a system for plasmid-based transformation enabling complementation of mutations; expression of foreign, modified, or reporter genes; and even targeted gene disruptions. This review summarizes the current status of the molecular genetic toolbox for Chlamydia species and highlights new insights into their biology and new challenges in the nascent field of Chlamydia ...

Chlamydia pecorum is a globally recognised pathogen of livestock and koalas. To date, comparative genomics of C. pecorum strains from sheep, cattle and koalas has revealed that only single nucleotide polymorphisms (SNPs) and a limited number of pseudogenes appear to contribute to the genetic diversity of this pathogen. No chlamydial plasmid has been detected in these strains despite its ubiquitous presence in almost all other chlamydial species. Genomic analyses have not previously included C. pecorum from porcine hosts. We sequenced the genome of three C. pecorum isolates from pigs with differing pathologies in order to re-evaluate the genetic differences and to update the phylogenetic relationships between C. pecorum from each of the hosts. Whole genome sequences for the three porcine C. pecorum isolates (L1, L17 and L71) were acquired using C. pecorum-specific sequence capture probes with culture-independent methods, and assembled in CLC Genomics Workbench. The pairwise
Chlamydiae are medically important bacteria responsible for a wide range of human infections and diseases. Repeated episodes of infection promote chronic inflammation associated with detrimental immune system-mediated pathologic changes. However, the true nature of chlamydial pathogenesis may encompass repeated infection superimposed upon persistent infection, which would allow for heightened immune reactivity. During the course of chlamydial infection, numerous host elaborated factors with inhibitory or modifying effects may cause alterations in the chlamydia-host cell relationship such that the organism is maintained in a nonproductive stage of growth. Abnormal or persistent chlamydiae have been recognized under a variety of cell culture systems. The numerous factors associated with altered growth suggest an innate flexibility in the developmental cycle of chlamydiae. This review evaluates in vitro studies of chlamydial persistence and correlates these model systems to features of natural ...

There are many reasons not to keep pet parrots. Theyre long-lived birds that require years, if not decades, of care. They can be messy and destructive. And, above all, many species are in danger of extinction and quelching the market for them is one helpful thing we can do. But, todays parasite is another reason. Chlamydophila psittaci is a species of bacteria that causes a very serious disease in both birds and mammals, including humans, known as psittacosis. These bacteria have a pretty unusual life cycle - they alternate between being intracellular bacteria in the lungs of their hosts and very resistant stages known as "elementary bodies." When engulfed by phagocytosis and attacked with a lysosome, the elementary bodies say "Ha!" and just begin to replicate instead - even going so far as to use some of the host cells own organelles. Eventually they kill the host cell and become elementary bodies again, ready to reinfect this host or be spread to another one. In 1929, a major outbreak of ...
Chlamydia species are obligate intracellular bacteria that infect a broad range of mammalian hosts. Members of related genera are pathogens of a variety of vertebrate and invertebrate species. Despite the diversity of Chlamydia, all species contain an outer membrane lipooligosaccharide (LOS) that is comprised of a genus-conserved, and genus-defining, trisaccharide 3-deoxy-D-manno-oct-2-ulosonic acid Kdo region. Recent studies with lipopolysaccharide inhibitors demonstrate that LOS is important for the C. trachomatis developmental cycle during RB- > EB differentiation. Here, we explore the effects of one of these inhibitors, LPC-011, on the developmental cycle of five chlamydial species. Sensitivity to the drug varied in some of the species and was conserved between others. We observed that inhibition of LOS biosynthesis in some chlamydial species induced formation of aberrant reticulate bodies, while in other species, no change was observed to the

2017 The Author(s). The order Chlamydiales are biphasic intracellular bacterial pathogens infecting humans and domesticated animals. Wildlife infections have also been reported, with the most studied example being Chlamydia pecorum infections in the koala, an iconic Australian marsupial. In koalas, molecular evidence suggests that spill-over from C. pecorum infected livestock imported into Australia may have had a historical or contemporary role. Despite preliminary evidence that other native Australian marsupials also carry C. pecorum, their potential as reservoirs of this pathogen and other Chlamydia-related bacteria (CRBs) has been understudied. Mucosal epithelial samples collected from over 200 native Australian marsupials of different species and geographic regions across Australia were PCR screened for Chlamydiales. Previously described and genetically distinct C. pecorum genotypes and a range of 16S rRNA genotypes sharing similarity to different CRBs in the broader Chlamydiales order were ...

A major risk factor which may contribute to Cp. psittaci zoonotic transmission concerns the fact that when pigeons increase their egg-laying rate there is a concomitant increase in bacterial excretion during egg incubation and chick feeding (12,19,20). This is particularly serious considering that residences windows and air conditioning spaces, especially bedrooms, are used by pigeons during breeding and feeding. Heddema et al., 2006 (19) reported that 5 %-10 % of pigeons faecal samples in urban populations in Amsterdam were infected with Cp. psittaci, although this work did not show zoonotic transmission events. However, the bacteria was detected directly in exposed populations clinical samples and faecal samples from birds collected by participants in this study which could have represented direct evidence of zoonotic transmission from birds to humans. Given that conventional serological, PCR-RFLP and real-time PCR techniques do not allow accurate discrimination of currently-known genotypes ...

The HIV pandemic continues with an estimated 13,000 new infections each day, the vast majority of which are acquired through heterosexual intercourse. Although consistent and correct use of condoms by men remains the most effective form of protection from heterosexually acquired HIV, women are not always able to negotiate condom use. An effective prophylactic vaccine remains a key objective, but development is slow because of virus variability and difficulty in determining the immunological correlates of protection. Vaginal microbicides are being developed in response to the urgent need for an HIV prevention method that women can control. Licensed spermicides containing nonoxynol-9 (N-9), which has potent anti-HIV activity in vitro, were the first products to be investigated as potential microbicides. However, the association of N-9 and other products belonging to this class (surfactants) with genital epithelial disruption, histologically determined genital inflammation, and reduction in ...
