The long-standing history of Corynebacterium parvum, immunity, and viruses.

J Med Virol 2020 May 30. Epub 2020 May 30.

Dental Department of Morphological Sciences Related to Transplant, Oncology and Regenerative Medicine, University of Modena and Reggio Emilia, Modena, Italy.

We report a review of all the experimental and clinical studies performed in the last 60 years on the antiviral activity of inactivated Corynebacterium parvum (Cutibacterium acnes). This bacterium has been originally investigated and used for its oncolytic properties linked to immunomodulating activity, but the interest to successfully prevent and treat bacterial, fungal, and viral infections and lethality, uprising the innate immunity barriers produced many experimental models and very few clinical studies. The dramatic defenseless situation due to impending CoViD-19 pandemic claims to exhume and highlight this aspecific strategy in preventive and therapeutic settings; as a matter of fact, no new or mutated virus can potentially escape to this strong innate immune surveillance strengthened by adequate C.

The Ability of Respiratory Commensal Bacteria to Beneficially Modulate the Lung Innate Immune Response Is a Strain Dependent Characteristic.

Microorganisms 2020 May 13;8(5). Epub 2020 May 13.

Laboratory of Immunobiotechnology, Reference Centre for Lactobacilli (CERELA-CONICET), 4000 Tucumán, Argentina.

We investigated whether the ability of commensal respiratory bacteria to modulate the innate immune response against bacterial and viral pathogens was a shared or strain-specific characteristic. Bacterial strains belonging to the and species were compared by studying their influence in the Toll-like receptor (TLR)-2- and TLR3-triggered immune responses in the respiratory tract, as well as in the resistance to Respiratory Syncytial Virus (RSV) and infections. We demonstrated that nasally administered 090104 or 040417 were able to modulate respiratory immunity and increase the resistance against pathogens, while other strains of the same species did not influence the respiratory immune responses, demonstrating a clear strain-dependent immunomodulatory effect of respiratory commensal bacteria.

The penile microbiota of Black South African men: relationship with human papillomavirus and HIV infection.

BMC Microbiol 2020 Apr 6;20(1):78. Epub 2020 Apr 6.

Institute of Infectious Disease and Molecular Medicine, University of Cape Town, Cape Town, South Africa.

Background: To date, the microbiota of the human penis has been studied mostly in connection with circumcision, HIV risk and female partner bacterial vaginosis (BV). These studies have shown that male circumcision reduces penile anaerobic bacteria, that greater abundance of penile anaerobic bacteria is correlated with increased cytokine levels and greater risk of HIV infection, and that the penile microbiota is an important harbour for BV-associated bacteria. While circumcision has been shown to significantly reduce the risk of acquiring human papillomavirus (HPV) infection, the relationship of the penile microbiota with HPV is still unknown. Read More

Development of an immunoassay using recombinant outer membrane protein A and flagellin for diagnosis of goats with melioidosis.

J Vet Med Sci 2020 Mar 29;82(3):325-332. Epub 2020 Jan 29.

General Research Service Center, National Pingtung University of Science and Technology, Pingtung, 91201, Taiwan.

Among domestic animals, melioidosis is one of the most common diseases reported in goat, sheep, and swine. To evaluate the specific antibodies in goats with melioidosis, we developed a serology test using recombinant outer membrane protein A (OmpA) and flagellin (FliC) of Burkholderia pseudomallei as antigens. DNA corresponding to each antigen was cloned into a pET32a vector and expressed in Escherichia coli. Read More

Diphtheria is an infectious disease caused by Corynebacterium diphtheriae. The bacterium primarily infects the throat and upper airways and the produced diphtheria toxin (DT), which binds to the elongation factor 2 and blocks protein synthesis, can spread through the bloodstream and affect organs, such as the heart and kidneys. For more than 125 years, the therapy against diphtheria has been based on polyclonal horse sera directed against DT (diphtheria antitoxin; DAT). Read More

Nasopharyngeal microbiota profiles in rural Venezuelan children are associated with respiratory and gastrointestinal infections.

Clin Infect Dis 2020 Jan 10. Epub 2020 Jan 10.

Department of Pediatric Infectious Diseases and Immunology, Wilhelmina Children's Hospital, University Medical Center Utrecht, Utrecht, The Netherlands.

Background: Recent research suggests that the microbiota affects susceptibility to both respiratory (RTI) and gastrointestinal (GII) infections. Past work has mainly focused on westernised populations and the gut microbiota. In order to optimise global treatment options, it is important to characterise microbiota profiles across different niches and geographic/socioeconomic areas where RTI and GII prevalences are high.

[Adverse reactions after repeated doses of anti-tetanus vaccine: scientific evidences].

Ig Sanita Pubbl 2019 Jul-Aug;75(4):317-325

Dipartimento di Biomedicina e Prevenzione, Tor Vergata Università degli Studi di Roma, Italia.

The possible risk of hyperimmunization after tetanus vaccination is currently discussed after the National Vaccine Prevention Plan 2017-2019 confirmed the recommendation of a booster dose every ten years. Due to the ubiquitous nature of tetanus spores and the inability to obtain herd-immunity through vaccination, efforts to reduce the incidence of tetanus aim at eliminating the disease. The only way to prevent infection is vaccination followed by recommended periodic booster doses. Read More

Unravelling of the interplay between the immune system and non-diphtheria corynebacteria would contribute to understanding their increasing role as medically important microorganisms. We aimed at the analysis of pro- (TNF, IL-1β, IL-6, IL-8, and IL-12p70) and anti-inflammatory (IL-10) cytokines produced by Jurkat T cells in response to planktonic and biofilm Two reference strains: ATCC 700207 (R-CA), ATCC 25923 (R-SA), and ten clinical strains of (C-CA) were used in the study. Jurkat T cells were stimulated by the planktonic-conditioned medium (PCM) and biofilm-conditioned medium (BCM) derived from the relevant cultures of the strains tested. Read More

Comparative analysis of the vaginal microbiome of pregnant women with either Trichomonas vaginalis or Chlamydia trachomatis.

PLoS One 2019 12;14(12):e0225545. Epub 2019 Dec 12.

KEMRI-Wellcome Trust Research Programme, Centre for Geographic Medicine Research-Coast, Kilifi, Kenya.

Background: Although the significance of the human vaginal microbiome for health and disease is increasingly acknowledged, there is paucity of data on the differences in the composition of the vaginal microbiome upon infection with different sexually transmitted pathogens.

Method: The composition of the vaginal bacterial community of women with Trichomonas vaginalis (TV, N = 18) was compared to that of women with Chlamydia trachomatis (CT, N = 14), and to that of controls (N = 21) (women negative for TV, CT and bacterial vaginosis). The vaginal bacterial composition was determined using high throughput sequencing with the Ion 16S metagenomics kit of the variable regions 2, 4 and 8 of the bacterial 16S ribosomal RNA gene from the vaginal swab DNA extract of the women.
