Pasteurella multocida is a gram-negative, opportunistic pathogen and the common inhabitant of the upper respiratory tract of domesticated and wild animal species. It is a causative agent of numerous economically important diseases worldwide, such as enzootic bronchopneumonia in ruminants and haemorrhagic septicemia in cattle and buffalo. The present study was undertaken to determine the prevale...

Background & Aims: Acinetobacter spp. are non-fermenting gram-negative coccobacilli that have emerged in recent three decades as major causes of nosocomial infections. Acinetobacter baumannii is the most common pathogen causing a wide spectrum of infections. Acinetobacter infections are difficult to treat, due to both the intrinsic resistance of the pathogen and its ability to readily acquire n...

Diaphorina citri is a serious insect pest of citrus and an vector Candidatus Liberibacter asiaticus (CLas) that causes Huanglongbing disease (citrus greening). In this study, we investigated the effect CLas pathogen on life history parameters D. at different temperature regimes. Our results demonstrated survival rate first to fifth instar CLas-positive CLas-negative fluctuate with change in ove...

We describe the molecular mode of action and pharmacodynamics of a new molecular entity (NME) that induces the NLRP3 inflammasome-mediated innate immune response. This innate response reduces the pathogen load in an experimentally induced methicillin-resistant Staphylococcos aureus infection, enhances survival in an experimentally induced Gram-negative bacteremia, and overrides the escape mecha...

Helicobacter pylori (H.pylori) is a gram-negative bacterium that has infected more than half of the world's population. This pathogen colonizes the human gastric mucosa and is usually acquired during childhood. It is an important cause of peptic ulcers, chronic gastritis and stomach cancer. Among the risk factors for acquisition of H. pylori infection, poor socioeconomic status, poor sanitizati...

Introduction.Staphylococcus caprae is a coagulase-negative staphylococcus that has been reported in several cases as a human pathogen. However, it has rarely been reported as pathogen in native bone. Furthermore, the reported MIC levels noted in the literature for vancomycin were <2 µg ml-1making vancomycin a first line choice for infected patients. Case presentation. We report a case of Staphy...

Campylobacter jejuni is a spiral-shaped Gram-negative pathogen and major agent of gastrointestinal foodborne illness in humans worldwide. This pathogen encodes numerous described pathogenicity-associated factors involved in important processes including bacterial adhesion to, transmigration across, invasion into and intracellular survival within intestinal epithelial cells. This review article ...

The amphibian pathogen Batrachochytrium dendrobatidis (Bd) has recently emerged as a primary factor behind declining global amphibian populations. Much about the basic biology of the pathogen is unknown, however, such as its true ecological niche and life cycle. Here we evaluated invertebrates as infection models by inoculating host species that had previously been suggested to be parasitized i...

The aim of this study was to estimate heritabilities of and genetic correlations between pathogen-specific subclinical mastitis (SCM) traits and lactation mean somatic cell score (LSCS) in Norwegian Red cattle. Based on data from 130 733 first-lactation cows four binary pathogen-specific SCM traits, Staphylococcus aureus, Streptococcus dysgalactiae, Streptococcus uberis and coagulase-negative s...
