Novirhabdoviruses like the Viral hemorrhagic septicemia virus (VHSV) are rhabdoviruses infecting fish. In the current study, RNA genomes of different VHSV field isolates classified as high, medium or low virulent phenotypes have been sequenced by next-generation sequencing and compared. Various amino acid changes, depending on the VHSV phenotype, have been identified in all the VHSV proteins. As a starting point, we focused our study on the non-virion (NV) non-structural protein in which an arginine residue (R116) is present in all the virulent isolates and replaced by a serine/asparagine residue S/N116 in the attenuated isolates...

Acute suppurative thyroiditis (AST) is an uncommon condition, in the patients with preexisting thyroid disease or immunosuppression. The most common cause of AST is bacterial, and the most common bacteria are Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli, and Klebsiella species. Due to various complications such as septicemia, septic thrombophlebitis, necrotizing mediastinitis, or pericarditis, prompt diagnosis and treatment are the keys to reduce mortality and morbidity. Here, we describe a case of a 40-year-old female with AST caused by Citrobacter freundii...

INTRODUCTION: Immediate success rates of renal transplantation (RT) procedures are generally very high. National estimates of the impact of post-operative complications, specifically, septicemia occurring during hospitalization for RT's on outcomes is unclear. We sought, to examine the prevalence of septicemia in patients having renal transplantation procedures and to quantify the impact of septicemia on in-hospital mortality (IHM), length of stay (LOS), and hospital charges (HC). MATERIALS AND METHODS: We performed a retrospective analysis of the Nationwide Inpatient Sample (NIS) for the years 2004 to 2010...

Aliivibrio salmonicida is the causative agent of cold-water vibriosis, a septicemia of farmed salmonid fish. The mechanisms of disease are not well described, and few virulence factors have been identified. However, a requirement for motility in the pathogenesis has been reported. Al. salmonicida is motile by the means of lophotrichous polar flagella, consisting of multiple flagellin subunits that are expressed simultaneously. Here we show that flagellin subunit FlaA, but not FlaD, is of major importance for motility in Al...

Infections caused by the facultative intracellular bacterial pathogen Piscirickettsia salmonis remains an unsolved problem for the aquaculture as no efficient treatments have been developed. As a result, substantial amounts of antibiotic have been used to limit salmonid rickettsial septicemia (SRS) disease outbreaks. The antibiotic usage has not reduced the occurrence, but lead to an increase in resistant strains, underlining the need for new treatment strategies. P. salmonis produce membrane vesicles (MVs); small spherical structures know to contain a variety of bacterial components, including proteins, lipopolysaccharides (LPS), DNA and RNA...

Myocardial Abscess (MA) is a rare life threatening condition mostly occurring secondary to underlying infective endocarditis. But it can also be found secondary to septicemia with some unknown focus of sepsis in the body. Development of MA as a consequence of left ventricular aneurysm (LVA) secondary to myocardial infarction is very rare. We report the case of 56 year old male, who presented with high grade fever and leukocytosis. On detailed evaluation, he was found to have a myocardial abscess with underlying LVA...

We present our data on granulocyte transfusions in children undergoing treatment for cancer and HSCT at our centre and their changing indications. In this retrospective observational analysis of children who received granulocytes from 2007 to 2015, we divided children receiving granulocytes into two groups-the first from January 2007 till December 2013 and the second from January 2014 till December 2015. This division is based on the change in our policy to use granulocytes within 48 h of septicemia as the incidence of drug resistant bacterial strains had increased at our centre...

We previously showed that chromosome 8 of A/J mice was associated with susceptibility to S. aureus infection. However, the specific genes responsible for this susceptibility are unknown. Chromosome substitution strain 8 (CSS8) mice, which have chromosome 8 from A/J but an otherwise C57BL/6J genome, were used to identify the genetic determinants of susceptibility to S. aureus on chromosome 8. Quantitative trait loci (QTL) mapping of S. aureus-infected N2 backcross mice (F1 [C8A] × C57BL/6J) identified a locus 83180780-88103009 (GRCm38/mm10) on A/J chromosome 8 that was linked to S...

Extra-intestinal pathogenic Escherichia coli (ExPEC) represent an emerging pathogen, with pandemic strains increasingly involved in cases of urinary tract infections (UTIs), bacteremia, and meningitis. In addition to affecting humans, the avian pathotype of ExPEC, avian pathogenic E. coli (APEC), causes severe economic losses to the poultry industry. Several studies have revealed overlapping characteristics between APEC and human ExPEC, leading to the hypothesis of a zoonotic potential of poultry strains. However, the description of certain important pandemic clones, such as Sequence Type 73 (ST73), has not been reported in food sources...

Listeria monocytogenes is a foodborne pathogen that causes septicemia, meningitis and chorioamnionitis and is associated with high mortality. Immunocompetent humans and animals, however, can tolerate high doses of L. monocytogenes without developing systemic disease. The intestinal microbiota provides colonization resistance against many orally acquired pathogens, and antibiotic-mediated depletion of the microbiota reduces host resistance to infection. Here we show that a diverse microbiota markedly reduces Listeria monocytogenes colonization of the gut lumen and prevents systemic dissemination...
