The analysis of the intramacrophagic virulome of Brucella suis deciphers the environment encountered by the pathogen inside the macrophage host cell. (1/78)

The pathogen Brucella suis resides and multiplies within a phagocytic vacuole of its host cell, the macrophage. The resulting complex relationship has been investigated by the analysis of the set of genes required for virulence, which we call intramacrophagic virulome. Ten thousand two hundred and seventy-two miniTn5 mutants of B. suis constitutively expressing gfp were screened by fluorescence microscopy for lack of intracellular multiplication in human macrophages. One hundred thirty-one such mutants affected in 59 different genes could be isolated, and a function was ascribed to 53 of them. We identified genes involved in (i) global adaptation to the intracellular environment, (ii) amino acid, and (iii) nucleotide synthesis, (iv) sugar metabolism, (v) oxidoreduction, (vi) nitrogen metabolism, (vii) regulation, (viii) disulphide bond formation, and (ix) lipopolysaccharide biosynthesis. Results led to the conclusion that the replicative compartment of B. suis is poor in nutrients and characterized by low oxygen tension, and that nitrate may be used for anaerobic respiration. Intramacrophagic virulome analysis hence allowed the description of the nature of the replicative vacuole of the pathogen in the macrophage and extended our understanding of the niche in which B. suis resides. We propose calling this specific compartment "brucellosome."  (+info)

Role of the Brucella suis lipopolysaccharide O antigen in phagosomal genesis and in inhibition of phagosome-lysosome fusion in murine macrophages. (2/78)

Brucella species are gram-negative, facultative intracellular bacteria that infect humans and animals. These organisms can survive and replicate within a membrane-bound compartment inside professional and nonprofessional phagocytic cells. Inhibition of phagosome-lysosome fusion has been proposed as a mechanism for intracellular survival in both cell types. However, the molecular mechanisms and the microbial factors involved are poorly understood. Smooth lipopolysaccharide (LPS) of Brucella has been reported to be an important virulence factor, although its precise role in pathogenesis is not yet clear. In this study, we show that the LPS O side chain is involved in inhibition of the early fusion between Brucella suis-containing phagosomes and lysosomes in murine macrophages. In contrast, the phagosomes containing rough mutants, which fail to express the O antigen, rapidly fuse with lysosomes. In addition, we show that rough mutants do not enter host cells by using lipid rafts, contrary to smooth strains. Thus, we propose that the LPS O chain might be a major factor that governs the early behavior of bacteria inside macrophages.  (+info)

Subversion and utilization of the host cell cyclic adenosine 5'-monophosphate/protein kinase A pathway by Brucella during macrophage infection. (3/78)

Brucella spp. are intramacrophage pathogens that induce chronic infections in a wide range of mammals, including domestic animals and humans. Therefore, the macrophage response to infection has important consequences for both the survival of phagocytosed bacteria and the further development of host immunity. However, very little is known about the macrophage cell signaling pathways initiated upon infection and the virulence strategy that Brucella use to counteract these responses and secure their survival. In a previous study, we have shown that macrophages activated by SR141716A, a ligand of the cannabinoid receptor CB1, acquired the capacity to control Brucella and observed that the CB1 receptor-triggering engages the microbicidal activity of phagocytes. To analyze the perturbation of cell signaling pathway during macrophage infection by Brucella, we hypothesized that SR141716A provides cell signaling that interferes with the bacterial message leading to inhibition of macrophage functions. As CB1 receptor belongs to the family of G protein-linked receptors, we explored the cAMP signaling pathway. In this study, we show that the CB1 ligand inhibited the bacteria-induced cell signaling. Taking advantage of this result, we then demonstrated that Brucella infection elicited a rapid activation of the cAMP/protein kinase A pathway. This activation resulted in a prolonged phosphorylation of the transcription factor CREB. We finally demonstrate that the activation of the cAMP/protein kinase A pathway is crucial for the survival and establishment of Brucella within macrophages. For the first time in phagocytes, we thus characterized a primordial virulence strategy of Brucella involving the host signaling pathway, a novel point of immune intervention of this virulent pathogen.  (+info)

Epitope mapping of the Brucella melitensis BP26 immunogenic protein: usefulness for diagnosis of sheep brucellosis. (4/78)

Sequencing of bp26, the gene encoding the Brucella sp. immunogenic BP26 periplasmic protein, was performed in the reference strains of Brucella abortus, B. suis, and B. ovis. The three bp26 sequences were almost identical to that published for B. melitensis 16M bp26, and only minor nucleotide substitutions, without modifying the amino acid sequence, were observed between species. The bp26 genes of the seven B. abortus biovar reference strains and B. abortus S19 and RB51 vaccine strains were also sequenced. Again, only minor differences were found. Surprisingly, the bp26 nucleotide sequence for B. abortus S19 was almost identical to that found for B. melitensis 16M and differed from the sequence described previously by others (O. L. Rossetti, A. I. Arese, M. L. Boschiroli, and S. L. Cravero, J. Clin. Microbiol. 34:165-169, 1996) for the same B. abortus strain. The epitope mapping of BP26, performed by using a panel of monoclonal antibodies and recombinant DNA techniques, allowed the identification of an immunodominant region of the protein interesting for the diagnosis of B. melitensis and B. ovis infection in sheep. A recombinant fusion protein containing this region of BP26 reacted indeed, in Western blotting, as the entire recombinant BP26 against sera from B. melitensis- or B. ovis-infected sheep while it avoided false-positive reactions observed with sera from Brucella-free sheep when using the entire recombinant BP26. Thus, use of this recombinant fusion protein instead the entire recombinant BP26 could improve the specific serological diagnosis of B. melitensis or B. ovis infection in sheep.  (+info)

Characterization of new members of the group 3 outer membrane protein family of Brucella spp. (5/78)

Impairment of the omp25 gene in Brucella spp. leads to attenuated strains and confers protection to the host. Omp25 and Omp31, whose functions remain unknown, were the first characterized members of group 3 outer membrane proteins (Omps) (25 to 34 kDa). Recently, genomic and proteomic approaches identified five new putative members of this family, some of which are produced in B. melitensis or B. abortus. In the present study, using protein microsequencing, we identified new members of group 3 Omps proteins produced in B. suis. Since several monoclonal antibodies (MAbs) against Omp25 cross-reacted with other members of group 3 Omps, we also performed Western immunoblotting to compare wild-type B. suis with mutants systematically having B. suis omp25-related genes knocked out. We demonstrate the production of three paralogs of Omp31 and/or Omp25 in B. suis, and the existence of a common site of signal peptide cleavage (AXAAD), which is very similar to that present in the five homologous Omps of Bartonella quintana. The seven group 3 Omps were classified in four-subgroups on the basis of percentage amino acid sequence identities: Omp25 alone, the Omp25b-Omp25c-Omp25d cluster, the Omp31/31b subgroup, and the less related Omp22 protein (also called Omp3b). Together with previous data, our results demonstrate that all new members of group 3 Omps are produced in B. suis or in other Brucella species and we propose a nomenclature that integrates all of these proteins to facilitate the understanding of future Brucella interspecies study results.  (+info)

VirB1 orthologs from Brucella suis and pKM101 complement defects of the lytic transglycosylase required for efficient type IV secretion from Agrobacterium tumefaciens. (6/78)

Type IV secretion systems mediate conjugative plasmid transfer as well as the translocation of virulence factors from various gram-negative pathogens to eukaryotic host cells. The translocation apparatus consists of 9 to 12 components, and the components from different organisms are believed to have similar functions. However, orthologs to proteins of the prototypical type IV system, VirB of Agrobacterium tumefaciens, typically share only 15 to 30% identical amino acids, and functional complementation between components of different type IV secretion systems has not been achieved. We here report a heterologous complementation in the case of A. tumefaciens virB1 defects with its orthologs from Brucella suis (VirB1s) and the IncN plasmid pKM101 (TraL). In contrast, expression of the genes encoding the VirB1 orthologs from the IncF plasmid (open reading frame 169) and from the Helicobacter pylori cag pathogenicity island (HP0523) did not complement VirB1 functions. The complementation of VirB1 activity was assessed by T-pilus formation, by tumor formation on wounded plants, by IncQ plasmid transfer, and by IncQ plasmid recipient assay. Replacement of the key active-site Glu residue by Ala abolished the complementation by VirB1 from B. suis and by TraL, demonstrating that heterologous complementation requires an intact lytic transglycosylase active site. In contrast, the VirB1 active-site mutant from A. tumefaciens retained considerable residual activity in various activity assays, implying that this protein exerts additional effects during the type IV secretion process.  (+info)

Impairment of intramacrophagic Brucella suis multiplication by human natural killer cells through a contact-dependent mechanism. (7/78)

Brucella spp. are facultative intracellular bacteria that can establish themselves and cause chronic disease in humans and animals. NK cells play a key role in host defense. They are implicated in an early immune response to a variety of pathogens. However, it was shown that they do not control Brucella infection in mice. On the other hand, NK cell activity is impaired in patients with acute brucellosis, and recently it was demonstrated that human NK cells mediate the killing of intramacrophagic Mycobacterium tuberculosis in in vitro infection. Therefore, we have analyzed the behavior of Brucella suis infecting isolated human macrophages in the presence of syngeneic NK cells. We show that (i) NK cells impair the intramacrophagic development of B. suis, a phenomenon enhanced by NK cell activators, such as interleukin-2; (ii) NK cells cultured in the presence of infected macrophages are highly activated and secrete gamma interferon and tumor necrosis factor alpha; (iii) impairment of bacterial multiplication inside infected cells is marginally associated with the cytokines produced during the early phase of macrophage-NK cell cocultures; (iv) direct cell-to-cell contact is required for NK cells to mediate the inhibition of B. suis development; and (v) inhibition of B. suis development results from an induction of NK cell cytotoxicity against infected macrophages. Altogether, these findings show that NK cells could participate early in controlling the intramacrophagic development of B. suis in humans. It seems thus reasonable to hypothesize a role for NK cells in the control of human brucellosis. However, by impairing the activity of these cells in the acute phase of the illness, the pathogen should avoid this control.  (+info)

Different responses of macrophages to smooth and rough Brucella spp.: relationship to virulence. (8/78)

By comparing smooth wild-type Brucella strains to their rough mutants, we show that the lipopolysaccharide (LPS) O side chain of pathogenic Brucella has a dramatic impact on macrophage activation. It favors the development of virulent Brucella by preventing the synthesis of immune mediators, important for host defense. We conclude that this O chain property is firmly linked to Brucella virulence.  (+info)

Modifies, by uridylylation and deuridylylation, the PII regulatory proteins (GlnB and homologs), in response to the nitrogen status of the cell that GlnD senses through the glutamine level. Under low glutamine levels, catalyzes the conversion of the PII proteins and UTP to PII-UMP and PPi, while under higher glutamine levels, GlnD hydrolyzes PII-UMP to PII and UMP (deuridylylation). Thus, controls uridylylation state and activity of the PII proteins, and plays an important role in the regulation of nitrogen assimilation and metabolism.
To analyze the strategy adopted by Brucella to develop within mononuclear cells, we examined whether Brucellainfection was able to positively or negatively modulate apoptosis in human monocytic phagocytes. The results of various analyses (DNA fragmentation, microscopic analysis, and flow cytometry analysis) showed that Brucella infection inhibited apoptosis which spontaneously occurs in human monocytes in the absence of an activation signal and rendered macrophagic cells resistant to apoptosis induced by immunological factors.. Although the Brucella-mediated effect on monocyte apoptosis was somewhat similar to the E. coli LPS effect (references24 and 28 and our results), convergent data demonstrated that Brucella LPS cannot account for the antiapoptotic properties of the live bacteria. (i) Experiments performed in the presence of neutralizing anti-TNF-α Ab showed that TNF-α, which plays a central role in Brucella(or E. coli) LPS-induced protection of monocytes, did not participate in the ...
Authors: JADRANKA ZUTIC, DJORDJE CVETOJEVIC, LJUBISA VELJOVIC, OLIVER RADANOVIC, SLOBODAN STANOJEVIC, BRANISLAV KURELJUSIC Abstract: The objective of this work was to present the first case of Brucella suis biovar 2 isolation in outdoor reared pigs in Serbia. B. suis biovar 2 has not previously been detected in Serbia, from either wild boar or outdoor reared pigs. In our case, brucellosis was discovered in the region of Srem, which geographically constitutes a part of northwestern Serbia. Outdoor reared pigs in the Srem region are part of an extensive breeding system in the field and woods. In the course of a random visit to a herd in the above-mentioned area, the animals owner discovered two aborted fetuses, thereafter presented for laboratory examinations. B. suis biovar 2 was isolated from both fetuses. Isolated strains were identified using both classical and molecular techniques, including genomic sequencing. Based on epizootiological data, we were unable to establish the source of ...
Terpenoids, also known as isoprenoids, are a large class of natural products consisting of isoprene (C5) units. There are two biosynthetic pathways, the mevalonate pathway [MD:M00095] and the non-mevalonate pathway or the MEP/DOXP pathway [MD:M00096], for the terpenoid building blocks: isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP). The action of prenyltransferases then generates higher-order building blocks: geranyl diphosphate (GPP), farsenyl diphosphate (FPP), and geranylgeranyl diphosphate (GGPP), which are the precursors of monoterpenoids (C10), sesquiterpenoids (C15), and diterpenoids (C20), respectively. Condensation of these building blocks gives rise to the precursors of sterols (C30) and carotenoids (C40). The MEP/DOXP pathway is absent in higher animals and fungi, but in green plants the MEP/DOXP and mevalonate pathways co-exist in separate cellular compartments. The MEP/DOXP pathway, operating in the plastids, is responsible for the formation of essential oil ...
An increasing number of dogs in New South Wales are being infected with swine brucellosis, a disease spread by feral pigs, which can also lead to infertility among humans.
WASHINGTON, Feb. 7, 2012-The U.S. Department of Agricultures Animal and Plant Health Inspection Service (APHIS) has drafted a proposed action plan that presents current thinking and concepts about modifications that could be made to our domestic programs for swine brucellosis (SB) and pseudorabies (PRV).. This action plan outlines a potential new approach to our regulations, said John R. Clifford, Deputy Administrator for APHIS Veterinary Services program. We recognize that our animal health status related to these diseases has changed, and wed like to bring our regulations up to date to address current risks.. No States have had recent outbreaks of SB or PRV in commercial production swine. Therefore, all States are currently considered free for SB and PRV and there are no restrictions on the interstate movement of any swine within the United States for these diseases. In recent years, APHIS has identified several swine herds throughout the United States that were infected with SB or PRV. ...
Using serology and bacterial culture, we determined the prevalence of Brucella spp. and the antibody to Brucella spp. in a feral swine (Sus scrofa) population in proximity to a cattle herd that was culture positive for Brucella abortus and Brucella suis in north-central Texas, USA. During a prospective cross-sectional quantitative study in April 2005, we collected blood and tissue samples from 40 feral swine within a 30-km radius of the infected herd. Serum samples were tested by the Rose Bengal test, particle concentration fluorescence immunoassay, and fluorescence polarization assay. In addition, tissue samples were cultured, and the Brucella species and biovar determined. Four feral swine were Brucella positive by serology, and two were culture positive for B. suis biovar 1. Of the culture-positive swine, one was concurrently antibody and culture positive, and one was culture positive only. The presumptive source of the B. suis infection in the index cattle herd was likely the surrounding feral swine
Human invariant NKT (iNKT) cells are a unique subset of T cells, which recognize glycolipids presented by the CD1d. Among the iNKT cells, several functionally distinct subsets have been characterized according to CD4 and/or CD8 co-receptor expression. The current study is focussed on the CD4(+) iNKT cell subset and its role in an anti-infectious response. We have examined the role of CD4(+) iNKT cells on the intracellular Brucella suis growth. Our results indicate that CD4(+) iNKT cells impair the intramacrophagic growth of Brucella. This inhibition is due to a combination of soluble and contact-dependent mechanisms: IFN-gamma is weakly involved while cytotoxic activities such as the induction of the Fas pathway and the release of lytic granules are major mechanisms. The impairment of Brucella growth by CD4(+) iNKT cells requires an interaction with CD1d on macrophage surface. Also, we have shown that although CD4 regulates several biological responses of CD4(+) iNKT cells, it is not involved in ...
Adherent and invasive Escherichia coli (AIEC) associated with Crohns disease are able to survive and to replicate extensively in active phagolysosomes within macrophages. AIEC-infected macrophages release large amounts of tumour necrosis factor-alpha (TNF-α) and do not undergo cell death. The aim of the present study was to determine what benefit AIEC bacteria could gain from inducing the release of large amounts of TNF-α by infected macrophages and to what extent the neutralization of TNF-α could affect AIEC intramacrophagic replication. Our results showed that the amount of TNF-α released by infected macrophages is correlated with the load of intramacrophagic AIEC bacteria and their intracellular replication. TNF-α secretion was not related to the number of bacteria entering host cells because when the number of bacteria internalized in macrophage was decreased by blocking lipid raft-dependent and clathrin-coated pits-dependent endocytosis, the amount of TNF-α secreted by infected ...

Streptococcus suis is a major porcine and zoonotic pathogen responsible for significant economic losses in the pig industry and an increasing number of human cases. Multiple isolates of S. suis show marked genomic diversity. Here, we report the analysis of whole genome sequences of nine pig isolates that caused disease typical of S. suis and had phenotypic characteristics of S. suis, but their genomes were divergent from those of many other S. suis isolates. Comparison of protein sequences predicted from divergent genomes with those from normal S. suis reduced the size of core genome from 793 to only 397 genes. Divergence was clear if phylogenetic analysis was performed on reduced core genes and MLST alleles. Phylogenies based on certain other genes (16S rRNA, sodA, recN, and cpn60) did not show divergence for all isolates, suggesting recombination between some divergent isolates with normal S. suis for these genes. Indeed, there is evidence of recent recombination between the divergent and ...

S. suis is an important swine pathogen which colonizes the surface of the upper respiratory tract and which can cause severe infections such as meningitis and septicemia. Thus, virulent S. suis strains have to invade deeper tissues and reach the blood circulation. Consequently, they have to adapt to different environments during infection. In the present study we analyzed protein expression patterns of S. suis in response to temperature shifts from 32 and 37 to 42°C in order to mimic the environmental temperature encountered by the bacteria during infection, i.e., colonization of the upper respiratory tract, invasion into deeper tissues, and fever. Two up-regulated proteins with apparent molecular sizes of 47 and 53 kDa were further characterized. We selected these proteins since both appeared to be associated with the cell wall (they were detected in the MAP fraction) and, as such, were putative surface proteins. Furthermore, it seemed that neither protein represented one of the common heat ...

The genus Brucella contains highly infectious species that are classified as biological threat agents. The timely detection and identification of the microorganism involved is essential for an effective response not only to biological warfare attacks but also to natural outbreaks. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) is a rapid method for the analysis of biological samples. The advantages of this method, compared to conventional techniques, are rapidity, cost-effectiveness, accuracy and suitability for the high-throughput identification of bacteria. Discrepancies between taxonomy and genetic relatedness on the species and biovar level complicate the development of detection and identification assays. In this study, the accurate identification of Brucella species using MALDI-TOF-MS was achieved by constructing a Brucella reference library based on multilocus variable-number tandem repeat analysis (MLVA) data. By comparing MS-spectra from Brucella
STAT1 makes an essential contribution to innate immunity against viral and intramacrophagic bacterial disease. The objective of our study was to reveal any contribution of non‐tyrosine‐phosphorylated STAT1 to innate immunity. Examining cells and organs of mice expressing a Stat1Y701F mutant, the first observation of note was the strong dependence of STAT1 expression on its tyrosine phosphorylation through tonic signaling. None of the tested stimuli, including L. monocytogenes infection, caused upregulation of the Stat1 gene in the absence of its tyrosine‐phosphorylated product. Therefore, effects of the U‐Stat pathway as defined by Stark and colleagues which rely on an increase in STAT abundance could not be examined. In addition, any results obtained for the immune response of Stat1Y701F cells or mice could not be compared to WT counterparts because a distinction between effects of tyrosine phosphorylation and effects of STAT1 abundance was not possible. To overcome this problem, we ...
Wild hogs are known to cause external damage to land, property and wildlife, but the internal diseases they carry are equally dangerous. More than 40 known diseases are traced to wild hogs, but the two most common in Mississippi are pseudorabies and swine brucellosis. Each can be deadly to livestock and domestic animals. The best way to prevent these infections is to trap and kill hogs rather than simply building fences to keep them out.

Streptococcus suis 2 (SS2) has evolved into a highly invasive pathogen responsible for two large-scale outbreaks of streptococcal toxic shock-like syndrome (STSLS) in China. Excessive inflammation stimulated by SS2 is considered a hallmark of STSLS, even it also plays important roles in other clinical symptoms of SS2-related disease, including meningitis, septicemia, and sudden death. However, the mechanism of SS2-caused excessive inflammation remains poorly understood. Here, a novel pro-inflammatory protein was identified (HP1330), which could induce robust expression of pro-inflammatory cytokines (TNF-α, MCP-1, and IL-1β) in RAW264.7 macrophages. To evaluate the role of HP1330 in SS2 virulence, an hp1330-deletion mutant (Δhp1330) was constructed. In vitro, hp1330 disruption led to a decreased pro-inflammatory ability of SS2 in RAW 264.7 macrophages. In vivo, Δhp1330 showed reduced lethality, pro-inflammatory activity, and bacterial loads in mice. To further elucidate the mechanism of HP1330
Streptococcus suis is a peanut-shaped, Gram-positive bacterium, and an important pathogen of pigs. Endemic in nearly all countries with an extensive pig industry, S. suis is also a zoonotic disease, capable of transmission to humans from pigs. Humans can be infected with S. suis when they handle infected pig carcasses or meat, especially with exposed cuts and abrasions on their hands. Human infection can be severe, with meningitis, septicaemia, endocarditis, and deafness as possible outcomes of infection. Fatal cases of S. suis are uncommon, but not unknown. Penicillin is the most common antibiotic used in treatment of S. suis infection; in cases with cardiac involvement (endocarditis), gentamicin should also be given for synergistic effect. The natural habitat of S. suis in pigs is the upper respiratory tract, particularly the tonsils and nasal cavity, and the alimentary and genital tracts. An individual pig can carry more than serotype in their nasal cavity. Incidence of disease varies but is ...
Mycoplasma suis, a member of the hemotrophic mycoplasma (HM) group, parasitize erythrocytes of pigs. Increasing evidence suggests that M. suis is also a zoonotic agent. Highly pathogenic strains of M. suis (e.g., M. suis KI3806) have been demonstrated to invade erythrocytes. This complete sequenced and manually annotated genome of M. suis KI3806 is the first available from this species and from the HM group. The DNA was isolated from blood samples of experimentally infected pigs due to the lack of an in vitro cultivation system. The small circular chromosome of 709,270 bp, encoding an unexpectedly high number of hypothetical proteins and limited transport and metabolic capacities, could reflect the unique lifestyle of HM on the surface of erythrocytes. ...
Typically comprised of ~12 different scaffold components, prokaryotic type IV secretion systems (T4SSs) translocate a variety of substrates across the cell envelope. Due to the ability to translocate large DNA segments (i.e., mobile genetic elements), some T4SSs contribute to the spread of antimicrobial resistance and virulence genes. Other T4SSs translocate smaller DNA segments and/or proteins into eukaryotic cells (e.g., arthropod, plant and human) in order to benefit bacterial survival. At least eight major groups of T4SSs are described and each group consists of minor variations on a common structural theme. Within a given bacterial genome, combinations of different T4SS groups can be encoded, and sometimes multiple copies of the same T4SS group can be present. As an example, two functionally divergent T4SSs (vir and trw) are found in many species of Bartonella, bacteria that are transmitted by arthropods such as ticks and fleas and cause a range of diseases including endocarditis. In species of
Streptococcus suis is an important pathogen of pigs and occasionally causes serious human disease. However, little is known about the S. suis population structure, the clonal relationships between strains, the potential of particular clones to cause disease, and the relevance of serotype as a marker for epidemiology. Here we describe a multilocus sequence typing (MLST) scheme for S. suis developed in order to begin to address these issues. Seven housekeeping gene fragments from each of 294 S. suis isolates obtained from various S. suis diseases and from asymptomatic carriage representing 28 serotypes and nine distinct countries of origin were sequenced. Between 32 and 46 alleles per locus were identified, giving the ability to distinguish , 1.6 x 10(11) sequence types (STs). However only 92 STs were identified in this study. Of the 92 STs 18 contained multiple isolates, the most common of which, ST1, was identified on 141 occasions from six countries. Assignment of the STs to lineages resulted ...
In order to understand more thoroughly the antibody response against M. suis, we sought to characterize M. suis-specific antigens in blood-derived preparations of the agent. For this, we modified our recently published protocol for gaining M. suis DNA by a density gradient centrifugation step that was described to efficiently separate hemotrophic mycoplasmas from erythrocytic membranes (1). The results of our Western blot studies show that M. suis expresses in vivo at least eight specific proteins, ranging from 33 to 83 kDa in size, which are recognized by convalescent-phase sera. To the best of our knowledge, this is the first analysis of M. suis-specific antigens. Due to the use of host-derived M. suis antigens, the antibody response measured is expected to exclusively target antigens expressed by M. suis within the porcine host. However, it is impossible at this time to conceive any precise function for these proteins.. Of particular note is the consistent detection of three protein bands ...
The use of E. suis specific primers in PCR with DNA from swine blood increases the sensitivity of current DNA hybridization protocols for determining whether swine are infected with E. suis prior to the development of any clinical symptoms. The present invention provides these E. suis primers and a method to use these primers in a PCR protocol to provide a highly sensitive diagnostic assay for early signs of an E. suis infection.

Streptococcus suis is a bacterium that threatens the health and well-being of pigs. S. suis infections are one of the most common reasons for the use of antibiotics in pig farming, particularly around weaning age. S. suis can cause serious symptoms and lead to meningitis, joint inflammation, blood poisoning and even death.

Susan Montoya Bryan AP Using the cover of darkness, feral pigs have learned to outsmart even the most seasoned hunters as they set about on their nightly terrors, rooting up crops and suburban gardens, harassing native wildlife and turning watering holes into pigsties. The invasive porkers have made themselves at home across more than three quarters of the U.S. and are responsible for an estimated $1.5 billion in damages each year. Most worrisome is their ability to learn from each encounter
