Meningomyeloradiculitis as an Unusual Presentation of Neuroborreliosis in Childhood

We report a pediatric case of Lyme neuroborreliosis-associated meningomyeloradiculitis with atypical manifestations and negative initial cerebrospinal fluid borrelial antibodies. Transverse myelitis and painful radiculoneuritis have rarely been described in pediatric neuroborreliosis. Clinical manifestations are wide ranging and nonspecific, and the serologic diagnosis is often delayed in the acute phase.info:eu-repo/semantics/publishedVersio

Detection of Rickettsia conorii strains in Portuguese dogs (Canis familiaris)

This study reports a serological and molecular survey on the spotted fever group Rickettsia found in a group of 51 dogs with suspected tick-borne illness from the south of Portugal. Additionally, a prevalence of IgG antibodies to R. conorii was also estimated in a group of 400 healthy dogs from the same region. In the group of healthy dogs, the immunofluorescence test revealed that 154 (38.5%) of the 400 dogs had IgG antibodies reactive with R. conorii. The highest proportion of dogs (45%) with R. conorii antibodies was found in blood samples collected from October to December. Among the group suspected with tick-borne illness, 35 (62%) dogs showed to be seroreactive (IgG≥128) for antibodies against R. conorii, and the analysis of PCR-positive amplicons revealed that 5 dogs were infected with R. conorii Malish and 2 dogs were infected with R. conorii Israeli tick typhus strain. There was a higher prevalence of antibodies to R. conorii in the group of sick dogs, and the detection of R. conorii DNA in blood samples from this group points to their potential role as a reservoir and sentinel host helping to evaluate and characterize the distribution of circulating rickettsial strains

Detection of mpox using polymerase chain reaction from the skin and oropharynx over the course of infection: A prospective study

Research LettersTo the Editor: Since early May 2022, 86,746 mpox virus (MPV) infections have been reported worldwide.1,2 However, its in vivo viral kinetics and infectivity remain unclear.3 We conducted a prospective observational study to determine how long MPV remains detectable in skin lesions and the oropharynx.
