Canine brucellosis, caused by Brucella canis, is a persistent infectious reproductive disease in dogs. The absence of effective treatment to the intracellular pathogen and the irreversible consequence of infection makes the need of a specific vaccine urgent. Bacterial ghosts (BGs) are the empty envelopes of bacteria with no genome content inside, which emerge as a proper vaccine candidate due to its intact outer antigen. It is generally derived from a genetically engineered strain, through the expression of Bacteriophage phiX174 lysis E gene upon induction...

BACKGROUND: Brucellosis is a severe zoonotic disease worldwide. Detection and identification of Brucella species are essential to prevent or treat brucellosis in humans and animals. The outer membrane protein-31 (Omp31) is a major protein of Brucellae except for B. abortus, while the Omp31 antigenic epitopes have not been extensively characterized yet. RESULTS: A total of 22 monoclonal antibodies (mAbs) were produced against Omp31 of Brucella (B.) melitensis, of which 13 recognized five linear epitopes, 7 reacted with semi-conformational epitopes and 2 reacted with conformational epitopes, respectively...

BACKGROUND: Brucellosis was a common human and livestock disease caused by Brucella strains, the category B priority pathogens by the US Center for Disease Control (CDC). Identified as a priority disease in human and livestock populations, the increasing incidence in recent years in China needs urgent control measures for this disease but the molecular background important for monitoring the epidemiology of Brucella strains at the national level is still lacking. METHODS: A total of 600 Brucella isolates collected during 60 years (from 1953 to 2013) in China were genotyped by multiple locus variable-number tandem repeat analysis (MLVA) and the variation degree of MLVA11 loci was calculated by the Hunter Gaston Diversity Index (HGDI) values...

Differentiation of Brucella canis from other Brucella species are mainly performed through PCR-based methods and multilocus variable-number tandem-repeat (VNTR) analysis (MLVA) procedures. Both PCR-based and MLVA methods are limited in discriminating B. canis strains. A new MLVA-13Bc method for B. canis genotyping was established by combining eight newly-developed VNTRs with five published ones. During 2010 and 2016, 377 B. canis PCR-positives were identified from 6,844 canine blood samples from 22 U.S. states, resulting in 229 B...

Brucella canis was recovered from dogs that were canine brucellosis suspect by blood culture using a modified lysis method. Organism identity was established by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS). The instrument-provided security library identified the isolates as Brucella species. The isolates were further identified as B. canis with the help of phenotypic and genotypic characteristics. The mass spectral profiles from characterized B. canis isolates, when added to the MALDI-TOF MS standard reference library, allowed successful presumptive identification of B...

Brucella infection in Hokkaido was serologically surveyed in four species of pinnipeds inhabiting Cape Erimo during 2008-2013 and the Shiretoko Peninsula in 1999 by ELISA using Brucella abortus and B. canis as antigens. Anti-Brucella positive sera showed higher absorbance to B. abortus than B. canis in almost all samples. Anti-B. abortus antibodies were detected in serum samples from 24% (n = 55) of Western Pacific harbor seals (Phoca vitulina stejnegeri) in Cape Erimo and from 66% (n = 41) of spotted seals (P...

Toxocariasis caused by Toxocara canis or less frequently by T.catis is a common parasitic infection worldwide. Clinical spectrum in humans can vary from asymptomatic infection to serious organ disfunction depending on the load of parasite, migration target of the larva and the inflammatory response of the host. Transverse myelitis (TM) due to toxocariasis is an uncommon illness identified mainly as case reports in literature. In this report, a case of TM who was diagnosed as neurotoxocariasis by serological findings has been presented...

Brucellosis is a globally important zoonotic infectious disease caused by gram negative bacteria of the genus Brucella. While many species of Brucella exist, Brucella melitensis, Brucella abortus, and Brucella suis are the most common pathogens of humans and livestock. The virulence of Brucella is largely influenced by its ability to evade host factors, including phagocytic killing mechanisms, which are critical for the host response to infection. The aim of this study was to characterize the bovine neutrophil response to virulent Brucella spp...

INTRODUCTION: Brucella spp. are gram-negative, facultative intracellular bacteria pathogens responsible for brucellosis, a zoonotic disease that can cause abortion, fetal death, and genital infections in animals and undulant fever in humans. Lipopolysaccharide (LPS) is known as a major virulence factor of Brucella spp. The wboA gene is capable of encoding a glycosyltransferase that appears to play a major role in LPS biosynthesis. Hence, the characterization of this gene can help in the clarification of the pathogenicity of Brucella spp...

A large breeding kennel of Bulldogs (n = 57) experienced several Canid herpesvirus 1 (CHV-1)-related diseases in older puppies (9 weeks of age) in Arkansas. CHV-1 has been repeatedly confirmed in the kennel in several animals for 3 years (January 2012-February 2015) using various virology tests. I was able to detect a partial sequence of CHV DNA (~120 bp) in archived formalin-fixed, paraffin-embedded tissue blocks after 3 years of storage. CHV-1 is persistently circulating in this kennel in spite of high serum antibody titers in the adult dogs...
