Brucella is an intracellular pathogen able to persist for long periods of time within the host and establish a chronic disease. We show that soon after Brucella inoculation in intestinal loops, dendritic cells from ileal Peyer's patches become infected and constitute a cell target for this pathogen. In vitro, we found that Brucella replicates within dendritic cells and hinders their functional ...

We examined the expression and activity of inducible nitric oxide synthase (iNOS) in both gamma interferon (IFN-gamma)-treated and untreated murine macrophages infected with the gram-negative bacterium Brucella suis. The bacteria were opsonized with a mouse serum containing specific antibrucella antibodies (ops-Brucella) or with a control nonimmune serum (c-Brucella). The involvement of the pro...

we report the case of a male patient with community‑acquired quadruple‑valve endocarditis on presumed normal native valves.this patient had originally presented elsewhere with generalized edema and malaise and had been diagnosed with suspicious endocarditis and renal dysfunction, for which he unfortunately received incomplete treatment. transthoracic and transesophageal echocardiographic ex...

Brucellosis is a zoonotic disease caused by Brucella sp. and may affect many parts of the body. Brucella epididymo-orchitis had been reported in up to 20% of patients with brucellosis. This is a case report of Brucella epididymo-orchitis in a Saudi male patient. He presented with a unilateral swelling of the left testicle. He had fever, arthralgia and night sweats. Ultrasound examination reveal...

discussion children with congenital heart disease are at risk of acquiring gram-negative endocarditis even if they have not had other predisposing factors. case presentation in this study a ten-year-old boy with ventricular septal defect, who was not immune compromised and acquired klebsiella endocarditis is introduced. the patient had a favorable response to medical treatment and underwent a s...

It has long been observed that smooth Brucella can dissociate into rough mutants that are cytotoxic to macrophages. However, the in vivo biological significance and/or mechanistic details of Brucella dissociation and cytotoxicity remain incomplete. In the current report, a plaque assay was developed using Brucella strains exhibiting varying degrees of cytotoxicity. Infected monolayers were obse...

Streptococcal bloodstream infections resulting in right-sided endocarditis are uncommon. Streptococcus mitis can demonstrate slow-growing potential leading to delayed presentation or culture-negative endocarditis. Endocarditis accompanied by skin lesions represents a severe disease course. Heparin-induced thrombocytopenia and disseminated intravascular coagulopathy complicating the require well...

Introduction: Infective endocarditis is a rare, fatal ,with high morbidity in children, Since infective endocarditis in children was not assessed in our conditions so our study was attempted.   Material and Methods: This cross-sectional  study  include 19 patients less than 18 years old  with endocarditis   were hospitalized in the Department of Pediatric Cardiology( University of Mashhad...

background: rapid diagnosis and differentiation of brucella is of high importance due to the side effects of antibiotics for the treatment of brucellosis. this study aimed to identify and compare pcr-elisa as a more accurate diagnositc test with other common molecular and serological tests. methods: in this experimental and sectional study, during march 2014 to sep 2015, 52 blood samples of sus...

INTRODUCTION The objectives of the present study were to determine the seroprevalence and identify the causative agent of brucellosis in small ruminants in Pakistan. METHODOLOGY A total of 278 serum and 212 milk samples were collected from sheep and goats that had close contact with seropositive bovine herds. Data related to age, sex, location, and breed were collected on the sampling day. Se...
