Serum and Salivary IgG and IgA Response After COVID-19 Messenger RNA Vaccination.

Importance: There is still considerable controversy in the literature regarding the capacity of intramuscular messenger RNA (mRNA) vaccination to induce a mucosal immune response.

Objective: To compare serum and salivary IgG and IgA levels among mRNA-vaccinated individuals with or without previous SARS-CoV-2 infection.

Design, Setting, And Participants: In this cohort study, SARS-CoV-2-naive participants and those with previous infection were consecutively included in the CoviCompare P and CoviCompare M mRNA vaccination trials and followed up to day 180 after vaccination with either the BNT162b2 (Pfizer-BioNTech) vaccine or the mRNA-1273 (Moderna) vaccine at the beginning of the COVID-19 vaccination campaign (from February 19 to June 8, 2021) in France.

Odontogenic cutaneous sinus tracts due to infection with nontuberculous mycobacteria: a report of three cases.

Background: Soft tissue or skin infections due to nontuberculous mycobacteria (NTM) have been reported frequently and are mostly associated with trauma or cosmetic interventions like plastic surgery. However, infection with NTM as a result of a dental procedure have rarely been described and the lack of clinical suspicion and a clear clinical manifestation makes diagnosis challenging.

Case Presentation: We report on three patients with a facial cutaneous sinus tract of dental origin, due to an infection with respectively Mycobacterium fortuitum, M.

Drug susceptibility patterns of rapidly growing mycobacteria isolated from skin and soft tissue infections in Venezuela.

To our knowledge, this is the first work on drug susceptibility patterns of rapid growing mycobacteria from Latin America. The susceptibility patterns for 14 antimicrobial agents of the three most important species that cause skin infections in Venezuela were determined as follows: 63 strains belonging to Mycobacterium abscessus group, 66 strains of the Mycobacterium fortuitum group, and 13 Mycobacterium chelonae strains. The M.

[Follow-up on an outbreak in Venezuela of soft-tissue infection due to Mycobacterium abscessus associated with Mesotherapy].

Introduction: Skin and soft tissue infections caused by nontuberculous mycobacteria (NMT) are reported to be associated with injections, liposuction, plastic surgery, and acupuncture. Herein, we describe an outbreak of soft tissue infection due to NMT following mesotherapy, a cosmetic procedure involving injection of poorly defined mixtures alleged to reduce local adiposity.

Methods: Patients with skin lesions and a history of mesotherapy treatment, who visited the dermatology department of the public hospital in Barinas, Venezuela, from November 2004 to February 2005 were interviewed.
