Abstract
Background. Pseudotuberculosis remains a serious healthcare problem, which determines the expediency of developing the express methods for its early diagnosis. To detect the pathogen, we designed test system for dot-immunoassay (DIA) based on antibodies labeled with silver nanoparticles (SNPs) isolated from hyperimmune rabbit serum obtained against killed cells of Yersinia pseudotuberculosis of O:1b serovariant.The aim. To assess the possibility of using dot-immunoassay for express identification of Y. pseudotuberculosis cultures isolated from clinical material and environmental objects at the initial stage of bacteriological study during laboratory diagnosis of the disease.Methods. We used the materials from the outbreak of pseudotuberculosis in the Krylovskaya Boarding School of the Bakcharsky district of the Tomsk region in 2021. Specific antibodies from hyperimmune rabbit sera obtained against Y. pseudotuberculosis 3704 particulate antigen of O:1b serotype were labeled with SNPs and used in DIA on nitrocellulose membranes with visualization of reaction results with a solution of a physical developer. The presence of the causative agent of pseudotuberculosis in the test material was inferred by the formation of gray spots of different intensity (from 4+ to 1+).Results. All Y. pseudotuberculosis strains isolated using bacteriological method on the second day of the study from clinical material obtained from sick people and environmental objects were detected in DIA at concentrations ≥ 3.1 × 104 microbial cells per milliliter (m.c./ml).Conclusion. The designed test system for dot-immunoassay using SNPs as a marker of specific antibodies for the detection of Y. pseudotuberculosis in cultures isolated from swabs from vegetables and clinical material from patients, including those with mixed infection, allows us to detect a specific corpuscular antigen with a high sensitivity (≥ 3.1 × 104 m.c./ml), providing express identification of isolated cultures at the initial stage of bacteriological study.

Abstract
Yersinia pseudotuberculosis is an important animal pathogen, particularly for birds, rodents, and monkeys, which is also able to infect humans. Indeed, an increasing number of reports have been published on zoo animals that were killed by this species. One option to treat diseased animals is the application of strictly lytic (virulent) phages. However, thus far relatively few phages infecting Y. pseudotuberculosis have been isolated and characterized. To determine the prevalence of Y. pseudotuberculosis phages in zoo animals, fecal samples of birds and some primates, maras, and peccaries kept in the Tierpark Berlin were analyzed. Seventeen out of 74 samples taken in 2013 and 2017 contained virulent phages. The isolated phages were analyzed in detail and could be allocated to three groups. The first group is composed of 10 T4-like phages (PYps2T taxon group: Myoviridae; Tevenvirinae; Tequatrovirus), the second group (PYps23T taxon group: Chaseviridae; Carltongylesvirus; Escherichia virus ST32) consists of five phages encoding a podovirus-like RNA polymerase that is related to an uncommon genus of myoviruses (e.g., Escherichia coli phage phiEcoM-GJ1), while the third group is comprised of two podoviruses (PYps50T taxon group: Autographiviridae; Studiervirinae; Berlinvirus) which are closely related to T7. The host range of the isolated phages differed significantly. Between 5.5 and 86.7% of 128 Y. pseudotuberculosis strains belonging to 20 serotypes were lysed by each phage. All phages were additionally able to lyse Y. enterocolitica B4/O:3 strains, when incubated at 37°C. Some phages also infected Y. pestis strains and even strains belonging to other genera of Enterobacteriaceae. A cocktail containing two of these phages would be able to lyse almost 93% of the tested Y. pseudotuberculosis strains. The study indicates that Y. pseudotuberculosis phages exhibiting a broad-host range can be isolated quite easily from zoo animals, particularly birds.

[PMID: 33247729 DOI: 10.1093/milmed/usaa518] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2020] [Revised: 10/19/2020] [Accepted: 11/14/2020] [Indexed: 11/14/2022] Open
Abstract
INTRODUCTION In the spring of 2014, there was an outbreak of Yersinia enterocolitica (YE) gastroenteritis in four Norwegian military camps-the largest outbreak ever reported in Norway. YE is usually transmitted via food, and the gastrointestinal disease caused by the bacterium is considered a public health problem in several countries. Common symptoms of YE gastroenteritis are abdominal pain, diarrhea, fever, nausea, and vomiting. Post-infectious complications can occur after YE gastroenteritis, the most common of which are erythema nodosum and reactive arthritis. Based on self-reported data, we describe the duration of illness, the duration of any absence from service, and the incidence of symptoms of post-infectious complications in two groups of servicepeople: one diagnosed with YE gastroenteritis and the other with an unspecified acute infectious gastroenteritis. MATERIALS AND METHODS The Norwegian Armed Forces Health Register (NAFHR) is a central health register that contains data from conscripts and from military and civilian personnel in the Norwegian Armed Forces. In this study, we identified all individuals with a diagnosis of YE gastroenteritis in the NAFHR in the period from January 1 to June 30, 2014 (n = 128) as well as all those with a diagnosis of an unspecified acute infectious gastroenteritis in the same period (n = 323) to participate as controls. In October 2018, a link to an internet-based questionnaire was distributed by e-mail to all identified individuals. The questionnaires collected data on the duration of illness, the duration of absence from service, and the incidence of symptoms of post-infectious complications. RESULTS Of all those who received the questionnaire, 72 (59%) were included in the YE group and 117 people (36%) were included in the control group. Half of those in the YE group were ill for more than 13 days, while almost all (90%) of those in the control group recovered after 1 week. There were no differences between the groups in the incidence of symptoms of post-infectious complications during the 6 weeks after recovery. There was a significantly larger proportion of officers than conscripts in the YE group who reported symptoms of post-infectious complications. None of the respondents reported symptoms of post-infectious complications in the 6 months after the termination of military service. CONCLUSION One strength of this study is that we were able to investigate a large outbreak of YE gastroenteritis in a group of individuals with good underlying health. Weaknesses are the low response rate, especially in the control group, and the fact that we sent out the questionnaire >4 years after the acute gastroenteritis occurred. YE gastroenteritis among personnel in the Norwegian Armed Forces was associated with a significantly longer duration of illness and a longer duration of absence from service than that resulting from an unspecified acute infectious gastroenteritis. However, YE gastroenteritis was not associated with more symptoms of post-infectious complications.

Abstract
Spondylarthritis (SpA) is one of the most frequent extraintestinal manifestations of chronic inflammatory bowel disease (IBD). Several arthritogenic enterobacterial infections can induce sequelae such as reactive SpA. Studies on the gut-synovium axis in view of genetic, immunological, clinical and therapeutic aspects has made enterogenic SpA a model disease of all forms of SpA. The same applies for investigating IBD, as subclinical gut inflammation seen in SpA patients has provided significant evidence for a better understanding of mucosa-associated early immune events in Crohn's disease (CD). This article summarizes the pathognomonic clinical features, diagnostic steps, differential diagnosis and current pathogenetic models of enterogenic SpA. Knowledge of pathogenetic contexts leads to concrete treatment recommendations. These vary individually depending on the underlying IBD, on the inflammatory intestinal or rheumatic activity and on the rheumatological manifestation pattern.

Abstract
Background: Arthritis may occur after the diagnosis of Kawasaki disease (KD). Most cases are self-limiting; however, some patients require prolonged treatment. Method: To characterize KD-related arthritis, 14 patients who required arthritis treatment within 30 days after the diagnosis of KD were recruited from the 23rd KD survey in Japan. Twenty-six additional patients were included from our tertiary center and literature review cohorts. Results: The estimated prevalence of KD-related arthritis in Japan was 48 per 100,000 KD patients. Patients with KD-related arthritis had an older age at onset (52 vs. 28 months, P = 0.002) and higher rate of intravenous immunoglobulin (IVIG) resistance in comparison to those without arthritis (86 vs. 17%, P < 0.001). Among 40 patients, 18 had arthritis in the acute phase KD (continued fever-onset type) and 22 did in the convalescent phase (interval fever-onset type). Both showed a similar rate of complete KD or IVIG response. Interval-type patients required biologics for arthritis control less frequently (5 vs. 39%, P = 0.02) and had a higher 2-year off-treatment rate (100 vs. 43%, P = 0.009) than continued-type ones. Interval-types showed lower serum ferritin and interleukin-18 levels than continued-types. When continued-types were grouped according to whether or not they required biologics (n = 7 and n = 11, respectively), the former subgroup had higher ferritin and interleukin-18 levels (P = 0.01 and 0.02, respectively). A canonical discriminant analysis differentiated interval-type from continued-type with the combination of age, time to arthritis, and the ferritin and matrix metalloproteinase-3 levels. Conclusion: Arthritis requiring treatment is a rare complication of KD. KD-associated arthritis includes interval-type (KD-reactive) and continued-type (true systemic-onset juvenile idiopathic arthritis [JIA] requiring biologics), and overlapping arthritis, suggesting the pathophysiological continuity of autoinflammation between KD and JIA.

Abstract
Was ist neu?
Epidemiologie und Pathogenese Campylobacter jejuni/enteritidis ist in Westeuropa zu einem der häufigsten Erreger der ReA geworden. Auch nach mit Reisediarrhö assoziierten Escherischia-coli-Infektionen (DEC-Infektionen) können Arthralgien und milde ReA auftreten. HLA-B27 spielt eine Rolle bei der Erregerinvasion und -persistenz in Zellen der Mukosa und als antigenpräsentierendes Molekül. Neu sind Erkenntnisse, dass durch Auslösung einer Unfolded Protein Response (UPR) als Folge einer Fehlfaltung des HLA-B27-Moleküls eine proinflammatorische Stressantwort ausgelöst werden kann und dass enterobakterielle Infektionen diese Reaktion des angeborenen Immunsystems auslösen oder verstärken.
Diagnostik Die Diagnostik beruht nicht auf einzelnen Parametern, sondern auf einer Kombination von klinischen, anamnestischen und serologischen bzw. PCR-basierten Faktoren.
Therapie Antibiotika werden nur zur Therapie einer noch bestehenden Chlamydophilia-trachomatis-Infektion an der Eintrittspforte (urogenital) eingesetzt, nicht aber zur Therapie der posturethritischen oder postenteritischen ReA. Bei therapierefraktären chronischen Verläufen können Biologika (TNF-Inhibitoren) entsprechend ihrer Zulassung bei Spondyloarthritiden eingesetzt werden.

Abstract
Yersinia pseudotuberculosis is a Gram-negative zoonosis which occasionally infects humans via ingestion of contaminated food and water, and typically causes a self-limiting gastrointestinal tract infection. Patients who are immunocompromised, have haemochromatosis or liver cirrhosis are more likely to develop serious complications such as bacteraemia. We present the case of a 76-year-old man with fever and an acutely tender, swollen right knee. Blood cultures were positive for Y. pseudotuberculosis, and 16s ribosomal PCR analysis of his knee aspirate confirmed septic arthritis. He was treated with intravenous ceftriaxone and made an excellent recovery following knee washout. Interestingly, our patient did not have any of the classic risk factors described in the literature, or history of exposure to the pathogen to explain his diagnosis. To our knowledge, this is only the second confirmed case of Y. pseudotuberculosis bacteraemia with septic arthritis, and the first to involve the knee joint.

Abstract
d-glycero-α-d-manno-heptose-1-phosphate guanylyltransferase (HddC) is the fourth enzyme synthesizing a building component of lipopolysaccharide (LPS) of Gram-negative bacteria. Since HddC is a potential new target to develop antibiotics, the analysis of the structural and functional relationship of the complex structure will lead to a better idea to design inhibitory compounds. X-ray crystallography and biochemical experiments to elucidate the guanine preference were performed based on the multiple sequence alignment. The crystal structure of HddC from Yersinia pseudotuberculosis (YPT) complexed with guanosine 5′-(β-amino)-diphosphate (GMPPN) has been determined at 1.55 Å resolution. Meanwhile, the mutants revealed their reduced guanine affinity, instead of acquiring noticeable pyrimidine affinity. The complex crystal structure revealed that GMPPN is docked in the catalytic site with the aid of Glu80 positioning on the conserved motif EXXPLGTGGA. In the HddC family, this motif is expected to recruit nucleotides through interacting with bases. The crystal structure shows that oxygen atoms of Glu80 forming two hydrogen bonds play a critical role in interaction with two nitrogen atoms of the guanine base of GMPPN. Interestingly, the binding of GMPPN induced the formation of an oxyanion hole-like conformation on the L(S/A/G)X(S/G) motif and consequently influenced on inducing a conformational shift of the region around Ser55.

Abstract
Yersinia pseudotuberculosis and Yersinia enterocolitica are ubiquitous pathogens with wildlife and domestic animal reservoirs. Outbreaks of 'non-plague' yersiniosis in man and non-human primates are reported frequently (including zoological specimens and research breeding colonies) and are usually characterized by enteritis, mesenteric lymphadenitis and occasionally organ abscessation. In people, non-septic reactive arthritis is a common sequela to yersiniosis. However, there have been rare reports in people of septic arthritis and osteomyelitis because of active systemic infection with Y. pseudotuberculosis. Osteomyelitis has also been reported rarely in historical yersiniosis outbreaks in farmed turkeys in England and the USA. This paper reports the first case of osteomyelitis caused by systemic infection with Y. pseudotuberculosis O:1 in a non-human primate, a captive ring-tailed lemur (Lemur catta). The lemur had a short clinical history of hyporexia and weight loss with reduction in mobility, especially of the left hindlimb. On post-mortem examination there was evidence of multi-organ abscessation. In addition, severe necrosis, inflammation and large bacterial colonies were present in the musculature, periosteum and bone marrow in the hip, ribs and a vertebra at the cervicothoracic junction. Osteomyelitis should be considered as a rare clinical presentation in non-human primates with systemic Y. pseudotuberculosis infection.

Abstract
Maximum growth temperature and growth limits in Luria-Bertani broth at different pH values and NaCl and ethanol concentrations were determined for 49 Yersinia pseudotuberculosis strains representing serotypes O:1, O:2, O:3, O:4, and O:5. In addition, the ability of the strains to grow at 0°C and the growth parameters at 1°C were determined. The maximum growth temperatures measured by Gradiplate temperature incubator varied between 42.2 and 43.7°C. All strains were able to grow at 0°C in Luria-Bertani broth within 17 days of incubation. At 1°C, differences were observed among strains in the maximum growth rates and area under the curve values based on optical density data, which suggests that some Y. pseudotuberculosis strains adapt faster to colder conditions. The mean maximum growth rates and area under the curve values at 1°C, as well as the mean maximum growth temperatures, were statistically significantly higher among serotype O:1 strains compared with O:3 strains and among biotype 1 compared with biotype 2 strains. All strains grew at pH 4.5, whereas none of the strains were able to grow at pH 4.2. The highest pH at which growth was observed varied between 9.0 and 9.3. For 14 strains the maximum NaCl concentration at which growth was observed was 4.8%, whereas 35 of the strains were able to grow at 5.0% NaCl. None of the strains showed growth at 5.2% NaCl. All strains were able to grow at 4.5% ethanol concentration (v/v), whereas 5.0% ethanol concentration was completely inhibitory to all strains. The observed limited physiological diversity among various Y. pseudotuberculosis strains may stem from the genetic homogeneity of the species.

Abstract
BACKGROUND The aim of this study was to explore the correlation between HLA-B27 and the intracellular elimination, replication, and trafficking of Salmonella enteritidis (S. enteritidis) collected from patients with reactive arthritis. MATERIAL AND METHODS Confocal microscopy, flow cytometry, and sandwich enzyme-linked immunosorbent assay (ELISA) were employed in this study to evaluate the localization of proteins of interest, to assess the intracellular trafficking of S. enteritidis, and to measure the production of cytokines of interest. RESULTS HLA-B27 was negatively associated with intracellular S. enteritidis elimination in healthy human monocytes/macrophages. In S. enteritidis infected monocytes/macrophages, HLA-27B was also negatively correlated with bacteria elimination but positively related to bacteria replication. S. enteritidis did not co-localize with NRAMP1 and LAMP1/2 in HLA-B27 cells. S. enteritidis did not co-exist with transferrin or dextran within HLA-B27 and A2 cells. CONCLUSIONS HLA-B27 is closely associated with the intracellular elimination and replication of S. enteritidis. Replicated bacteria in HLA-B27 monocytic cells were located within unique vacuoles rather than disturbing host endocytosis.

Abstract
Yersinia enterocolitica (YE) biotype 1A is generally considered non-pathogenic, and the role of it in causing reactive musculoskeletal complications is unclear. We evaluated the capability of YE biotype 1A to induce reactive arthritis (ReA) and other reactive musculoskeletal symptoms. Analysis of self-reported musculoskeletal symptoms was supplemented with a telephone interview (with a permission to acquire copies of patient files from a local physician or hospital) and/or clinical examination of subjects with recent musculoskeletal symptoms after a positive stool culture for YE. The diagnoses of ReA and reactive tendinitis and enthesitis (ReTe) were defined as "definite" when based on clinical examination and/or on interview by phone and "probable" when based solely on the questionnaire. Of 120 subjects, who reported musculoskeletal symptoms, 100 were included in the final analysis. Among these 100 patients, 68% had YE biotype 1A, 16% YE bio/serotype 4, and 1% biotype 2 infection; the remaining 15% had different YE-like strains or a non-biotypable strain. Of the 21 patients with ReA and of the 14 patients with ReTe, the diagnosis was definite in 9 and 7 patients and probable in 12 and 7 patients, respectively. The clinical picture of ReA caused by YE biotype 1A was similar with other bio/serotypes of YE. The definite ReA due to YE biotype 1A occurred in middle-aged adults (5 men, 4 women) with the most frequently affected joints being the knees and ankles. We suggest that YE biotype 1A should be taken into account as a new trigger of ReA.
