Monoclonal Antibodies for the Diagnosis of Borrelia crocidurae.

Monoclonal Antibodies for the Diagnosis of Borrelia crocidurae. Am J Trop Med Hyg. 2015 Nov 23; Authors: Aurélien FF, Mediannikov O, Nappez C, Azza S, Raoult D, Drancourt M Abstract Relapsing fever borreliae, produced by ectoparasite-borne Borrelia species, cause mild to deadly bacteremia and miscarriage. In the perspective of developing inexpensive assays for the rapid detection of relapsing fever borreliae, we produced 12 monoclonal antibodies (MAbs) against Borrelia crocidurae and characterized the two exhibiting the highest titers. P3A10 MAb reacts with the 35.6-kDa flagellin B (flaB) of B. crocidurae while P6D9 MAb recognizes a 35.1-kDa variable-like protein (Vlp) in B. crocidurae and a 35.2-kDa Vlp in Borrelia duttonii. Indirect immunofluorescence assay incorporating relapsing fever and Lyme group borreliae and 11 blood-borne organisms responsible for fever in West Africa confirmed the reactivity of these two MAbs. Combining these two MAbs in indirect immunofluorescence assays detected relapsing fever borreliae including B. crocidurae in ticks and the blood of febrile Senegalese patients. Both antibodies could be incorporated into inexpensive and stable formats suited for the rapid point-of-care diagnosis of relapsing fever. These first-ever MAbs directed against African relapsing fever borreliae are available for the scientific community to promote research in this neglected field.

It’s finally getting warm here in New England, and most of us have plans to enjoy the beautiful weather. And that’s why the Centers for Disease Control and Prevention (CDC) recently released a report raising awareness about how to prevent the tickborne infections that typically occur during this time of the year. Lyme disease is probably the most well-known, and the one for which diagnosis and treatment are most controversial. What is Lyme disease? Several countries around the world, especially in the Northern Hemisphere, and all 50 states in the US have already reported cases of Lyme. The disease is caused by ...

By Michelle Catenacci, M.DCHICAGO, Jun 18 2018 (IPS)Fertility health is an incredibly personal – and often vulnerable – topic. Fertility, infertility, and fertility preservation have gained increased public interest over the past few years. Infertility is formally defined as the inability to achieve pregnancy after one year of unprotected intercourse. The Centers for Disease Control and Prevention (CDC) reports that approximately 12% of women aged 15 to 44 in the United States have difficulty getting pregnant or carrying a pregnancy to term. Even though a significant proportion of the population suffers from th...

ConclusionsHigh rates of recurrent normal/abnormal karyotypes were observed in all groups with a majority of embryos presenting with recurrent abnormal morphology. Secondary RPL presented significantly more often with recurrent abnormal morphology compared to primary RPL. These findings offer prognostic information for the affected patient and might impact treatment choice.

(Natural News) Research published in the European Journal of Microbiology and Immunology revealed yet another sweet benefit of stevia. Known for its natural sweetening properties, stevia was discovered to be a safer and even more effective alternative to conventional, toxic antibiotics in treating Lyme disease. The researchers from the University of New Haven used an alcohol extract...

In this study, possible role of another Oligopeptide ABC transporter, OppA4 in ospC expression was investigated by construction of an oppA4 deletion mutant and the complemented strain. Inactivation of oppA4 resulted an increased production of OspC, suggesting that OppA4 has a negative impact on ospC expression. Expression of ospC is controlled by Rrp2-RpoN-RpoS, the central pathway essential for mammal infection. We showed that increased ospC expression in the oppA4 mutant was due to an increased rpoS expression. We then further investigated how OppA4 negatively regulates this pathway. Two regulators, BosR and BadR, are kn...

ConclusionsAntithrombin deficiency is associated with an increased risk of venous thromboembolic events with a 50% risk of thromboembolic events before the 50th year of life. It is a rare condition, so data concerning the optimal management during pregnancy are limited. The selection of patients who should receive low molecular weight heparin prophylaxis as well as dose intensity and monitoring are discussed. In our patient a conventional low molecular weight heparin dose proved to be inadequate at least at the laboratory level.

Immune imbalance at the maternal-fetal interface plays a fundamental role in the pathogenesis of unexplained recurrent spontaneous abortion (URSA). Human amniotic epithelial cells (hAECs) possess pregnancy-friendly immunomodulatory effects. Here, we investigated how function of naive CD4+ T cells from URSA patients is affected by hAECs.

Authors: Li X, Yin M, Gu J, Hou Y, Tian F, Sun F Abstract BACKGROUND Gas chromatography coupled with mass spectrometry (GC-MS) and liquid chromatography coupled with mass spectrometry (LC-MS) metabolomics have been deployed to detect novel differential metabolites in cases with recurrent spontaneous abortion (RSA). MATERIAL AND METHODS Fifty patients who had recurrent spontaneous abortions (RSAs) and 51 control patients (age, gestational age, and body mass index (BMI) match) were enrolled in this study. Untargeted GC-MS and targeted LC-MS were combined to discover and validate the different metabolomic profiles bet...
