We found no association between lack of sanitation and pathogen detection (adjusted risk ratio 0.95 ) compared with specimens from children served by sewerage. We used generalized estimating equations to assess reported risk factors for detecting >1 pathogen in stool. We detected genes associated with >1 targets in 26% of specimens, most frequently Clostridioides difficile (6.6%), atypical enteropathogenic Escherichia coli (6.1%), and enteroaggregative E. We used quantitative reverse transcription PCR to measure key pathogens in stool that may be associated with water and sanitation, as an indicator of exposure. We collected stool from school-age children from 352 households living in the Black Belt region of Alabama, USA, where sanitation infrastructure is lacking. The frequency of resistant viruses remains relatively low (<1%) compared with the total number of patients treated with tecovirimat. Most resistant isolates were associated with severely immunocompromised mpox patients on multiple courses of tecovirimat treatment, whereas most isolates identified by routine surveillance of patients not treated with tecovirimat remained sensitive. We tested 124 isolates from 68 patients 96 isolates from 46 patients were found to have a resistant phenotype. Resistant phenotype was determined using a viral cytopathic effect assay. Genomic sequencing identified 11 mutations previously reported to cause resistance, along with 13 novel mutations. The MPXV F13L gene homologue encodes the target of tecovirimat, and single amino acid changes in F13 are known to cause resistance to tecovirimat. Overall antimicrobial susceptibilities were similar across the 3 study sites.ĭuring the 2022 multinational outbreak of monkeypox virus (MPXV) infection, the antiviral drug tecovirimat (TPOXX SIGA Technologies, Inc., ) was deployed in the United States on a large scale for the first time. farcinica (16.1%) among non–transplant patients. cyriacigeorgica (19.5%) were the most common isolates among transplant recipients and N. Manifestations included isolated pulmonary nocardiosis among 73.2% of transplant and 84.4% of non–transplant patients and central nervous system involvement among 12.2% of transplant and 3.2% of non–transplant patients. cyriacigeorgica in Arizona (41.4%), and N. Among 268 patients with invasive nocardiosis, 48.2% were from Minnesota, 32.4% from Arizona, and 19.4% from Florida. We reviewed invasive Nocardia infections in 3 noncontiguous geographic areas in the United States during 2011–2018.
