#' @title Tuberculosis isolates in France
#'
#' @description
#' The genotypes of 1,641 tuberculosis isolates from France, typed

#' along with exemplary metadata regarding pulmonary localization of disease
#' and sputum smear positivity for acid-fast bacilli.
#' @format

#' \item{}{\code{meta}} is dataframe with two logical columns: \code{afb} denotes presence of acid-fast bacilli in sputum smear
#' and \code{lung} denotes pulmonary infection (TB-positive culture or molecular test from a respiratory sample).
