https://www.selleckchem.com/products/Methazolastone.html Erysipelothrix rhusiopathiae is a gram-positive bacillus causing three clinical syndromes in humans, including localized cutaneous infection, diffuse cutaneous form, and systemic infection. Various skin lesions in systemic form have been reported; however, no comprehensive study has been conducted. Here we report a case of a 60-year-old woman who suffered from E. rhusiopathiae bacteremia with distinct generalized annular purplish plaques. Negative microbiological studies of the lesional skin sample combined with the histopathological study showing diffuse neutrophilic infiltration confirm the diagnosis of Sweet syndrome. This study documents Sweet syndrome as one of the cutaneous manifestations in systemic E. rhusiopathiae infection.Localized tetanus is a rare form of tetanus and generally has a better prognosis, but it could become fatal when it progresses into generalized tetanus. Treatment is challenging as there are limited data about clinical management and factors preventing localized tetanus progression. We present a case of localized tetanus in left lower limb of 8 year-old boy which progressed into generalized tetanus.We present a case of infective endocarditis (IE) on a prosthetic pulmonary valve in a 36-year-old patient with tetralogy of Fallot (TOF). The patient underwent valve replacement surgery and active antibiotic treatment against Gram-negative cocci (Piperacillin Tazobactam then Ceftriaxone) for a total duration of 42 days with a favourable outcome. The causative agent was Neisseria mucosa which was identified on the infected valve by sequencing of 16S ribosomal RNA. To our knowledge, this is the first described case of a N. mucosa infective endocarditis on a pulmonary valve. Initially, serologies performed in clinical settings by immunofluorescence for Coxiella burnetii antibodies showed a major increase in phase I IgG titers at 1024 (normal values less then 16) corresponding with the diagn
