A 1-day-old male newborn was born with respiratory distress, low birth weight, hepatosplenomegaly, and bullous targetoid skin lesions over the face, back, buttocks, and extremities. A diagnosis of early congenital syphilis was made based on a treponemal serologic test. Pathologic examination of the skin lesion showed scattered dyskeratotic cells in the epidermis and interface dermatitis consistent with erythema multiforme. No spirochete could be found in the skin sections staining with Warthin-Starry stain. Using nested polymerase chain reaction, treponemal genomic DNA fragments encoding DNA polymerase I were detected.

Equine herpesvirus 1 (EHV-1) is a common pathogen of the horse which may induce mild respiratory distress, abortion, neonatal death and neurological disease. A single nucleotide polymorphism in the EHV-1 DNA polymerase (ORF30 A(2254) to G(2254)) has been associated with clinical signs of Equine herpes myeloencephalopathy (EHM). The aim of this work was to analyze the ORF30 genomic region among a panel of EHV-1 DNA extract in order to estimate the prevalence of the EHV-1 neuropathogenic genotype in France. Samples coming from cases associated with EHM, horses with respiratory symptoms and aborted mares, each obtained between 2002 and 2009, were investigated. DNA was directly extracted from biological samples and allelic discrimination was performed using real-time PCR. Thirty of the 125 analysed horses (24%) presented the G(2254) genotype of ORF 30. Among them, 7/16 were provided by EHM cases, 1/24 by respiratory cases and 22/85 by abortion cases. Concerning EHM, the 7 G(2254) genotype of ORF30 were all isolated in 2009 during two outbreaks where mortality was observed. Regarding the 22 G(2254) genotype of ORF 30, 17 were identified in foetuses on which EHV-1 was detected by PCR, without any certainty of viral implication in the abortion. These findings clearly suggest that other factors need to be considered for a better understanding of the impact of DNA polymerase genotype upon EHV-1 neuropathogenic phenotype.

Severe pulmonary involvement in malaria has been frequently reported in cases of Plasmodium falciparum infection but rarely in vivax malaria. We look at a case of a 38-year-old man living in a malaria endemic area who presented with acute respiratory distress syndrome (ARDS) caused by P. vivax. DNA polymerase chain reaction (PCR) confirmed that it was not a mixed infection. After specific antimalarial therapy and intensive supportive care, the patient was discharged from the hospital. This case illustrates that P. vivax-induced ARDS is not uncommon and should be readily recognized by the treating physicians. A confirmatory test with PCR is required in order to exclude P. falciparum co-infection.
