Abstract The interaction of Corynebacterium diphtheriae and closely related species with host cells is much more complex than originally thought when these bacteria were considered as extracellular pathogens. Host-pathogen studies revealed a wide range virulence factors contributing to adhesion, invasion, cell damage varying degrees. In combination, lead the successful colonization systems.

Infectious diseases remain a global threat with many people annually contracting the epidemic diseases. Improved understanding of the pathogenesis of bacteria, viruses, fungi, and parasites, along with rapid diagnosis and treatment of human infections are essential to improving infectious diseases outcomes worldwide. In many genomic loci in bacteria and archea, termed Clustered Regularly Inters...

Background and Objective: In the current study, the relevance of the respiratory infection with the age, sex, and seasonal variation of the year were studied side by side with the determination of the responsible bacterial pathogen and their antibiotic sensitivity patterns. Materials and Methods: One hundred sputum samples were collected to determine the causative bacteria of respiratory distr...

A nested reverse transcriptase (RT) PCR assay detected mRNA of the salmonid pathogen Renibacterium salmoninarum in samples of RNA extracts of between 1 and 10 cells. Total RNA was extracted from cultured bacteria, Atlantic salmon (Salmo salar L.) kidney tissue and ovarian fluid seeded with the pathogen, and kidney tissue from both experimentally challenged and commercially raised fish. Followin...

Bacteria of the Salmonella genus cause diseases ranging from gastroenteritis to life-threatening typhoid fever and are among the most successful intracellular pathogens known. After the invasion of the eukaryotic cell, Salmonella exhibits contrasting lifestyles with different replication rates and subcellular locations. Although Salmonella hyper-replicates in the cytosol of certain host cell ty...

OBJECTIVE To assess the significance of the Streptococcus anginosus group in intracranial complications of pediatric patients with rhinosinusitis. DESIGN Retrospective cohort study. SETTING Tertiary pediatric hospital. PATIENTS A 20-year review of medical records identified patients with intracranial complications resulting from rhinosinusitis. In the 50 cases identified, S anginosus was ...

Current pathogen detection systems lack the stability, sensitivity, and time-independent functionality required for real-time biosensing in the field. Antibodies exhibit specificity for pathogenic bacteria but lack the sensitivity to detect reduced pathogen levels and the stability needed for detection in harsh environments. We are investigating naturally occurring antimicrobial peptides (AMPs)...

The scavenger receptor cysteine-rich (SRCR) proteins form an archaic group of metazoan proteins characterized by the presence of SRCR domains. These proteins are classified in group A and B based on the number of conserved cysteine residues in their SRCR domains, i.e. six for group A and eight for group B. The protein DMBT1 (deleted in malignant brain tumors 1), which is identical to salivary a...

Human-induced changes in biogeochemical cycles alter the availability of carbon (C), nitrogen (N) and phosphorus (P) environment, leading to elemental stoichiometry primary producers. These ratios may, turn, degree stoichiometric mismatch between producer hosts their pathogens. Here, we outline how ecological could be used as a framework predict effects changing nutrient supply on mismatches au...
