Abstract
OBJECTIVES qnr genes are plasmid-mediated quinolone resistance genes. Five qnr families have been described with several alleles (7 alleles of qnrA, 53 alleles of qnrB, 1 allele of qnrC, 1 allele of qnrD and 6 alleles of qnrS). Their detection requires a PCR specific for each qnr family and further sequencing for allele characterization. METHODS High-resolution melt curve analysis (HRMA) was coupled to multiplex and simplex real-time PCR assays for detection and characterization of qnrA, qnrB and qnrS alleles. The protocol was set using 27 reference strains harbouring the most frequent alleles and was applied to 55 clinical isolates unknown for qnr positivity. RESULTS Out of the 27 reference strains tested, 21 alleles showed distinct profiles using HRMA: 6 qnrA, 12 qnrB and 3 qnrS. For the qnrB alleles showing similar profiles, we gathered them into four groups that were easily distinguished. For the alleles that we could not test, in silico analysis showed that they would be identified using the HRMA protocol set. Among the clinical isolates, 28 qnr-positive isolates were detected and the qnr allele was characterized as 8 qnrA1, 4 qnrB1, 5 qnrB2, 3 qnrB4, 1 qnrB8, 1 qnrB5, 3 qnrS1 and 1 qnrS2, with concordant results with PCR sequencing. Two new qnrB alleles were detected and distinguished using HMRA. They were further designated as qnrB25 and qnrB42. CONCLUSIONS We developed an HRMA assay for characterizing the qnr alleles in clinical isolates. This high-throughput method can be used to screen a large number of isolates. This method allowed the detection of new qnrB alleles.

Preliminary investigation of a mice model of Klebsiella pneumoniae subsp. ozaenae induced pneumonia. Microbes Infect 2011; 13:1045-51. [PMID: 21723409 DOI: 10.1016/j.micinf.2011.05.013] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2011] [Revised: 05/09/2011] [Accepted: 05/31/2011] [Indexed: 12/28/2022]
Abstract
In the present study, we comparatively assessed the pathophysiological mechanisms developed during lung infection of BALB/C female mice infected by an original wild type Klebsiella pneumoniae subsp. ozaenae strain (CH137) or by a referent subspecies K. pneumoniae. subsp. pneumoniae strain (ATCC10031). The mice infected with 2.10⁶ CFU K. p. subsp. pneumoniae (n = 10) showed transient signs of infection and all of them recovered. All of those infected with 1.10⁶ CFU K. p. subsp. ozaenae (n = 10) developed pneumonia within 24 h and died between 48 and 72 h. Few macrophages, numerous polymorphonuclear cells and lymphocytes were observed in their lungs in opposite to K. p. subsp. pneumoniae. In bronchoalveolar lavage, a significant increase in MIP-2, IL-6, KC and MCP-1 levels was only observed in K. p. subsp. ozaenae infected mice whereas high levels of TNF-α were evidenced with the two subspecies. Our findings indicated a lethal effect of a wild type K. p. subsp. ozaenae strain by acute pneumonia reflecting an insufficient alveolar macrophage response. This model might be of a major interest to comparatively explore the pathogenicity of K. p. subsp ozaenae strains and to further explore the physiopathological mechanisms of gram-negative bacteria induced human pneumonia.

Human Bocavirus quantitative DNA detection in French children hospitalized for acute bronchiolitis. J Clin Virol 2008; 43:142-7. [PMID: 18644746 PMCID: PMC7172587 DOI: 10.1016/j.jcv.2008.05.010] [Citation(s) in RCA: 51] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2007] [Revised: 04/02/2008] [Accepted: 05/01/2008] [Indexed: 12/21/2022]
Abstract
Background Human Bocavirus (HBoV) is a newly discovered parvovirus whose role as a causative agent of respiratory disease remains unclear. Study design We investigated the presence of HBoV by quantitative PCR in the nasopharyngeal samples of 192 French children consecutively hospitalized for acute bronchiolitis. Other common respiratory viruses were detected using immunofluorescence assays, cell culture detection, or RT-PCR assays. Results HBoV was detected in 24 (12.5%) of 192 study children. In 14/192 cases (7%) HBoV was the sole isolate and in 10/192 (5%) it was part of a mixed viral infection. HBoV was the third most common pathogen detected after respiratory syncytial virus (45/192; 23%) and rhinovirus (24/192; 12%). It occurred more often in infants aged 1–12 months (P = 0.002). Median levels of HBoV DNA genome in respiratory samples were significantly higher in patients with single HBoV infection than in patients with mixed respiratory viral infection with HBoV (4 × 108 copies/ml vs. 2 × 103 copies/ml, P < 0.001). Conclusions Our data suggest that HBoV at a high viral load could be an etiologic agent of respiratory tract disease, whereas the exact role of HBoV at a low viral load, as etiological cause or as pathophysiological co-factor of respiratory diseases, remains to be determined.

Abstract
We assessed the genetic and the antigenic variability within the env gene of peripheral blood human immunodeficiency virus (HIV) type 1 (HIV-1) group O populations during the natural course of a female heterosexual infection. Our data revealed the existence of a significant increase in amino acid sequence variability within the C2-V3 and gp41 regions (P = 0.023 and P < 0.001, respectively) in association with substitutions within neutralizing epitope sequences usually selected for HIV serological assays. These antigenic variations might significantly decrease the sensitivity of classical HIV enzyme-linked immunosorbent assays with blood samples of subjects heterosexually infected by HIV-1 group O strains. These findings may be of significant use both to devise diagnostic tools and to pursue suitable therapeutic modalities in cases of heterosexual infection by outlier HIV-1 strains.

Abstract
JC and BK human polyomaviruses (family Polyomaviridae) may cause severe neurological or urinary tract pathologies in immunocompromised hosts. In the present study, we evaluated a new commercially available PCR and microplate colorimetric hybridization assay for the standardized differential detection of JC virus (JCV) and BK virus (BKV) genomes in clinical samples. This JC/BK Consensus test was first evaluated by testing serial dilutions of JCV or BKV plasmid DNA standards and was then compared with an in-house reference PCR assay for the detection of JC and BK virus genomes in 70 cerebrospinal fluid (CSF) samples of patients with neurological disorders and in 75 serum or plasma samples and 125 urine samples of renal graft recipients. This new test allowed a limit of detection of 10 copies and 1 copy of JC and BK virus genomes, respectively, and was able to differentiate various levels of JCV, BKV, and mixed JCV and BKV DNA genomes in a single reaction tube. Our results showed 100% specificity and sensitivity for the JC/BK Consensus test with CSF samples. With serum or plasma samples, this test had a sensitivity and a specificity of 100% for both JCV and mixed JCV and BKV DNA detection and a sensitivity and a specificity of 100 and 97.8% for BKV DNA detection, respectively. With urine samples, the sensitivity and specificity were 100 and 96.6%, respectively, for JCV DNA detection; 100 and 89.4%, respectively, for BKV DNA detection; and 44.4 and 100%, respectively, for mixed JCV and BKV DNA detection. In conclusion, our data indicate that this new test, the JC/BK Consensus test, is valuable for the sensitive and specific differential detection of single JCV and BKV infections in CSF, serum or plasma, and urine samples. The use of this reliable PCR assay would improve the routine virological diagnosis as well as the clinical care of immunocompromised patients with polyomavirus-related pathologies.

Abstract
Enteroviruses (EVs) (Picornaviridae) in the female genital tract may constitute possible sources of antenatal or perinatal infection. The presence of EV genomes in the acellular part of cervicovaginal lavages of 119 non-pregnant childbearing-aged African women was determined using a semiquantitative RT-PCR and hybridization detection assay. EV-specific cervicovaginal IgA and IgG antibodies were also detected by immunocapture ELISA assays. Of 119 CVS samples tested, only 10 (8%) were positive for the detection of EV RNA, demonstrating an genital shedding of EVs in African woman. EV-RNA positivity was not associated with the HIV serostatus or with the presence of semen traces in female genital secretion. The microwell hybridization assay of EV amplified RT-PCR products indicated the presence of low levels of EV genomes, ranging from 50 to 100 RNA copies per ml of genital fluids. EV-specific cervicovaginal IgA or IgG antibodies were detected only in two hemoglobin-positive cervicovaginal secretions samples from women without genital EVs. The lack of EV specific IgA or IgG antibody secretion by the cervicovaginal mucosa supported the hypothesis of genital shedding of EVs without ongoing viral replication in the female genital tract. In conclusion, the findings demonstrated the presence of EV genomes in nearly 10% of childbearing-aged women living in Central Africa, and provided the basis of possible antenatal or perinatal transmission of EV from mother-to-child.

Abstract
BACKGROUND Human rhinoviruses and enteroviruses (Picornaviridae) are suspected to be major viral etiological causes of bronchiolitis in infants. OBJECTIVES In the present study, we assessed the potential role of the respiratory picornaviruses as causative agents of bronchiolitis in French infants. STUDY DESIGN From September 2001 to June 2002, we prospectively selected 192 infants < or =36 months of age and hospitalized for acute bronchiolitis. The detection of common respiratory viruses (respiratory syncytial virus, influenza virus A and B, parainfluenza virus 1, 2, 3 and adenovirus) was performed using classical immunofluorescence antigen and cell-culture detection assays on nasopharyngeal aspirates whereas the detection of human metapneumovirus (HMPV) was performed by a real-time RT-PCR assay. The presence of rhinovirus and/or enterovirus was assessed in respiratory samples by a picornavirus RT-PCR detection assay followed by a differential Southern blotting procedure. RESULTS A potential causative virus was detected in 72.5% of the 192 study infants. RSV (30%), rhinovirus (21%), enterovirus (9%), influenza virus A (6%) and human metapneumovirus (4%) were the most frequent causative agents detected. Rhinoviruses or enteroviruses were detected as the only evidence of respiratory viral tract infection in 57 (30%) of 192 infants, whereas rhinovirus or enterovirus occurred in mixed viral infection detected in 25 (13%) of 192 study cases (30% versus 13%, p<10(-3)). CONCLUSIONS Our data suggest that respiratory picornaviruses are one of the leading etiological causes of bronchiolitis in French infants. These findings highlight the need to implement a rapid picornavirus RT-PCR detection assay for the clinical diagnosis of respiratory infections in pediatric patients with bronchiolitis.

Abstract
Human metapneumovirus (HMPV) was the unique viral pathogen detected by a real-time reverse transcriptase PCR (RT-PCR) assay in 6 (6.4%) of 94 consecutive French children hospitalized for acute bronchiolitis from September 2001 to June 2002. This virus was identified as the third etiological cause of bronchiolitis, after respiratory syncytial virus and rhinovirus (35 [37%] and 21 [22%] of 94 cases, respectively). Phylogenetic analysis of F-gene sequences demonstrated the cocirculation of distinct HMPV genotypes during this study. These findings highlight the need to implement a rapid HMPV RT-PCR detection assay for the clinical diagnosis of respiratory infections in pediatric patients with bronchiolitis.

Abstract
Enterovirus (EV) detection by a new commercially available reverse transcription (RT)-PCR assay (Penter RT-PCR test) was compared with EV isolation from cell cultures and with EV detection by an in-house RT-PCR assay. Of the 54 cerebrospinal fluid specimens collected during a summer outbreak of aseptic meningitis, 52% were positive by cell culture versus 76% by in-house RT-PCR assay and 80% by the new RT-PCR test (52 versus 76 versus 80%; P = 0.003). This new reliable EV RNA detection test is suitable for clinical diagnosis of EV-related meningitis and may improve the management of EV-related neurological syndromes.

Abstract
INTRODUCTION In order to study whether the removal of potassium in haemodialysis patients could be increased, we analyzed the kinetics of potassium transfer in the dialyzer. METHOD 40 patients were included in the study. We studied: a) in vitro potassium exchanges between erythrocytes and plasma; b) plasma and erythrocyte potassium concentrations at dialyzer input and output; c) potassium transfers into the dialysate, using plasma clearance and direct measurement in the collected dialysate and d) erythrocyte potassium concentrations at the beginning and the end of dialysis. RESULTS In vitro, there is virtually no potassium transfer between erythrocytes and plasma. In vivo, erythrocyte potassium concentration is not affected by the dialyzer (98.7 +/- 6.4 mmol/l to 97.7 +/- 7.5 mmol/l, p = NS). Potassium transfer levels determined by calculated plasma clearance were similar to values obtained by measuring potassium in dialysate (0.71 +/- 0.10 mmol/min vs 0.68 +/- 0.10 mmol/min, p = NS). These results suggest that erythrocytes do not participate in potassium exchange in the dialyzer. This was confirmed by measured erythrocyte potassium concentrations, which were the same at the beginning and the end of dialysis (104.0 +/- 5.6 mmol/l vs 104.2 +/- 5.0 mmol/l, p = NS).

Abstract
JC virus (JCV) induces progressive multifocal leukoencephalopathy (PML), especially in human immunodeficiency virus (HIV)-infected patients. Although JCV genotypes have primarily been associated with geographic patterns, a distinctive neuropathogenicity was recently attributed to genotype 2. A multicenter study was conducted to describe the distribution of JCV genotypes in France and to investigate correlations between genotypes and PML. Genotypes were determined by sequencing 494 bp in the VP1 capsid gene. Peripheral JCV was studied in 65 urine samples from 43 HIV-infected patients and from 22 control subjects. Genotypes 1, 4, 2, and 3 were detected in 52.3%, 30.8%, 12.3%, and 4.6% of the samples, respectively. In 56 brain or cerebrospinal fluid samples, PML-associated JCV of genotypes 1, 2, 4, and 3 was found in 66%, 19.7%, 8.9%, and 5.4%, respectively. Infection with JCV genotypes 1 or 2 was correlated with PML (odds ratio, 3.29). On the other hand, infection with JCV genotype 4 could represent a lower risk for PML.

Abstract
Progressive Multifocal Leukoencephalopathy (PML) is a severe demyelinating disease, which is rapidly fatal and is due to JC virus (JCV) infection, which especially occurs in HIV-infected patients. To investigate JCV pathophysiology and to evaluate the predictive value of JCV detection in blood, we looked for JCV DNA in leukocytes and plasma of 96 patients without any neurological symptoms and 109 patients with neurological diseases, among whom 19 were suffering from PML. JCV genome was detected in about 18% of all patients, i.e. 15.6% of patients with central nervous system disorders except PML, 13.5% of patients without neurological symptoms and significantly more often in PML patients (47.6%). Both leukocytes and plasma were tested; in plasma, JCV DNA was found in 36.1% of positive patients and in cells in 80.5%. Surprisingly in seven instances only the plasma contained JCV genome. One-year follow-up of these patients showed that the absence of JCV DNA in blood was associated with a very low probability of developing PML (negative predictive value=0.99).

Abstract
A 72-year-old woman was admitted in 1984 for painful protrusive osteoarthritis of the left hip diagnosed as systemic mastocytosis with bone lesions and clinical features of intestinal malabsorption but no clinical skin lesion. The total hip replacement, refused in a first step because of the bone pathology, was carried out two years later. Signs of loosening appeared after one year. In 1990, following a traumatic bicondylar fracture of the left knee, an osteosynthesis was carried out. Ten days later, a shaft pathologic fracture of the femur above the osteosynthesis plate implied another open reduction. Two and a half years later, the patient is able to walk short distances, using walking sticks, and lives at home receiving social assistance.

Abstract
Cerebrospinal fluid (CSF) from 12 AIDS patients with clinical signs consistent with progressive multifocal leukoencephalopathy (PML) was examined by the polymerase chain reaction (PCR) for the presence of JC virus (JCV). A specific JCV target sequence was amplified in the CSF from 9 of the 12 patients and also in brain tissue from all nine JCV-positive patients. The clinical course, neuroimaging features, and, in four cases, histopathology of brain tissue proved that the nine patients had PML. In the other three patients with central nervous system disorders, the JCV genome was undetectable by PCR and Southern blot analysis in CSF and brain tissue. The clinical course and neuroimaging features ruled out PML in these three patients. Five CSF samples and five brain tissue specimens from 10 PML-free AIDS patients with central nervous system disorders were all negative for the JCV genome by PCR and Southern blot analysis. These results show that detection of JCV in CSF by PCR is a good alternative to brain tissue studies for the virological diagnosis of PML in AIDS patients.
