Absence of association between persistent skin lesion and virological replication in severe disseminated monkeypox infection in solid organ transplant recipient.

The Monkeypox (mpox) virus outbreak has been controlled worldwide. We report the case of a combined pancreas-kidney transplant recipient who presented a severe and prolonged cutaneous infection with onset of 3 successive rashes while receiving tecovirimat therapy. During follow-up, skin lesions, blood and throat samples were collected. Viral culture and mpox PCR were performed. No positive viral culture was obtained from blood and throat. The lowest mpox CT-values were obtained early after onset of skin lesions and were more likely to be associated with positive viral cultures. Furthermore, we observed persistent skin lesions up to 3 months. On these persistent lesions, mpox PCR positives were obtained but were not associated with positive viral culture after 23 days. In this immunocompromised host, who was receiving tecovirimat, in accordance with existing recommendations a 21-day isolation period appeared to be adapted. That said, isolation should not be systematically extended if complete healing of skin lesions has not been achieved.

Secondary syphilis in a 14-month-old girl and child-to-mother transmission.

Syphilis cases in childhood are usually associated with congenital transmission. Acquired transmission is uncommon, and primarily related to sexual abuse or close contact/nursing with infected family members. We here describe a case of syphilis in a 14-month-old girl resulting from intrafamilial infection, with a subsequent transmission to her mother.

Oropharyngeal samples versus lesion specimens at diagnosis in patients infected with monkeypox virus in Northern France.

The ongoing outbreak of monkeypox virus (MPXV) is the largest one in historically non-endemic countries. Early reports described atypical epidemiological and clinical presentations. We investigated MPXV DNA detection in oropharyngeal samples (OPS), and compared the viral load to that in lesion samples at diagnosis in patients infected with MPXV. We retrospectively included patients suspected to have monkeypox in Northern France, who underwent a MPXV PCR in the Virology Laboratory, University Hospital of Lille, from May 23 to August 18, 2022. Overall, a total of 228 patients (376 samples) were included. A positive result in at least one sample was found in 138 patients (60.5%). We compared PCR results between OPS and lesion samples (i.e., cutaneous or anal/rectal samples) in patients with both samples. A positive result in OPS was observed in 54 out of 60 patients (90%). The viral load in OPS (median Ct value = 29.5; interquartile range [IQR] = 24.7-34) was significantly lower than that in lesion samples (median Ct  value = 17.8; IQR = 16.3 and 19.7) (p < 0.0001). This report shows that pharyngeal sampling does not bring additional information for the initial diagnosis in patients presenting with typical lesions.

Aspergillosis in a colony of Humboldt penguins (Spheniscus humboldti) under managed care: a clinical and environmental investigation in a French zoological park.

Aspergillosis is pervasive in bird populations, especially those under human care. Its management can be critically impacted by exposure to high levels of conidia and by resistance to azole drugs. The fungal contamination in the environment of a Humboldt penguin (Spheniscus humboldti) group, housed in a French zoological park next to numerous large crop fields, was assessed through three serial sessions of surface sampling in nests, in 2018-20: all isolates were counted and characterized by sequencing. When identified as Aspergillus fumigatus, they were systematically screened for resistance mutations in the cyp51A gene and tested for minimal inhibitory concentrations (MICs) determination. At the same time, the clinical incidence of aspergillosis was evaluated in the penguin population by the means of systematic necropsy and mycological investigations. A microsatellite-based analysis tracked the circulation of A. fumigatus strains. Environmental investigations highlighted the substantial increase of the fungal load during the summer season (>12-fold vs. the other timepoints) and a large overrepresentation of species belonging to the Aspergillus section Fumigati, ranging from 22.7 to 94.6% relative prevalence. Only one cryptic species was detected (A. nishimurae), and one isolate exhibited G138S resistance mutation with elevated MICs. The overall incidence of aspergillosis was measured at ∼3.4% case-years, and mostly in juveniles. The analysis of microsatellite polymorphism revealed a high level of genetic diversity among A. fumigatus clinical isolates. In contrast, one environmental strain appeared largely overrepresented during the summer sampling session. In all, the rural location of the zoo did not influence the emergence of resistant strains.
