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 ...

Abstract Person search is of great significance to public safety research, such as crime surveillance, video surveillance and security. a method locating identifying the queried person from complete set images. The main cause false recall missed detection in presence occlusion In order improve accuracy when be occluded, this paper proposes an attention-based one-stage framework for (ABOS) using...

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...

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...

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...

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...

A whole-cell hybridization assay with fluorescent oligonucleotide probes derived from the 16S rRNA sequence of Brucella abortus in combination with flow cytometry has been developed. With the three fluorescent probes selected, a positive signal was observed with all the representative strains of the species and biovars of Brucella and with a total of nine different Brucella clinical isolates. U...

The effects of doxycycline-streptomycin-rifampin versus a standard doxycycline-streptomycin regimen on residual Brucella DNA were compared in 36 acute brucellosis patients. At admission, all patients given triple (n = 22) and double (n = 14) regimens had detectable Brucella DNA with similar mean loads (P = 0.982). At follow-up, 14 to 20 months postpresentation, significantly more patients recei...

BACKGROUND The indications and criteria for meniscal repair are expanding in parallel with new understanding in biomechanics, joint pathophysiology, and increased physician education. PURPOSE To describe the practice patterns of arthroscopic meniscal treatment in recent years, compare the trends of arthroscopic meniscal repair versus arthroscopic meniscectomy, and compare sports fellowship-tr...
