  3. Isolation and identification of sporozoite membrane protein of Cryptosporidium parvum and evaluation of calmodulin‐like protein immune protection

    • Parasite Immunology
    • Parasite Immunology, Accepted Article. Until now, no completely effective parasite-specific drugs or vaccines have been approved for the treatment of cryptosporidiosis. Through the separation and identification of the sporozoite membrane protein of Cryptosporidium parvum (C. parvum), 20 related proteins were obtained.

  4. RNA-Based Therapy for Cryptosporidium parvum Infection: Proof-of-Concept Studies

    • Infection and Immunity
    • Infection and Immunity, Ahead of Print. Cryptosporidium is a leading cause of moderate-to-severe diarrhea in children, which is one of the major causes of death in children under 5 years old. Nitazoxanide is the only FDA-approved treatment for cryptosporidiosis. However, it has limited efficacy in immunosuppressed patients and malnourished children. Therefore, it is urgent to develop novel therapies against this parasite.

  5. Growth Kinetics of Listeria monocytogenes on Cut Red Cabbage

    • Listeria monocytogenes is a foodborne pathogen associated with fresh produce vectors such as leafy greens. Recent outbreaks and recalls associated with red cabbage-containing salads have brought attention to this food commodity. While data on the proliferation of L. monocytogenes is available for different varieties of white cabbage, no information is available on the fate of this pathogen on red cabbage. The aim of this study was therefore to explore the survival of L.

  6. Efficacy of Antimicrobial Interventions Used in Meat Processing Plants against Antimicrobial Tolerant of Non-Antibiotic Resistant (Non-ABR) and Antibiotic Resistant (ABR) Salmonella on Fresh Beef

    • Salmonella is a common cause of foodborne illness in the United States and several strains of Salmonella have been identified as resistant to antibiotics. It is not known whether strains with antibiotics resistance (ABR) and some tolerance to antimicrobial compounds also have the ability to resist the inactivation effects of antimicrobial interventions used in the fresh meat processing.

  7. Impact of chlorinated water on pathogen inactivation during wheat tempering and resulting flour quality

    • Outbreaks of enteric pathogens linked to wheat flour have led the wheat milling industry to seek solutions addressing this food safety concern. Chlorinated water at 400-700ppm has been used in the flour milling industry as a tempering aid to control growth of yeast and mold in tempering bins. However, the effectiveness of chlorinated water for inactivating enteric pathogens on wheat kernels remained unknown.

  14. Delineating the Role of the msaABCR Operon in Staphylococcal Overflow Metabolism

    • Frontiers in Microbiology
    • Staphylococcus aureus is an important human pathogen that can infect almost every organ system, resulting in a high incidence of morbidity and mortality. The msaABCR operon is an important regulator of several staphylococcal phenotypes, including biofilm development, cell wall crosslinking, antibiotic resistance, oxidative stress, and acute and chronic implant-associated osteomyelitis.

    • Frontiers in Microbiology
    • Staphylococcus aureus is one of the main pathogens causing hospital and community-acquired infections, in particular, infections caused by methicillin-resistant Staphylococcus aureus (MRSA) cause a higher mortality rate than those caused by methicillin-sensitive strains, which poses a serious global public health problem. Therefore, rapid and ultrasensitive detection of patients with clinical MRSA infection and timely control of infection are essential.

  16. Identification and analysis of Rap–Phr system in Bacillus cereus 0–9

    • FEMS Microbiology Letters
    • In this study, eight rap-related genes were found in the Bacillus cereus 0–9 genome; five rap genes were located on chromosomes and three on large plasmids. A total of five Rap proteins in B. cereus 0–9 were annotated as ‘tetratricopeptide repeat proteins’. SMART Server analysis showed that the eight Rap proteins had typical tetrapeptide repeat sequence (TPR) domains.

  19. Proteomic Comparison of Ivermectin Sensitive and Resistant Staphylococcus aureus Clinical Isolates Reveals Key Efflux Pumps as Possible Resistance Determinants

    • Antibiotics
    • Ivermectin (IVM) is a versatile drug used against many microorganisms. Staphylococcus aureus is one of the most devastating microorganisms. IVM sensitive and resistant S. aureus strains were recently reported. However, the underlying molecular mechanisms of resistance are unknown. Clinical isolates of S. aureus were used for determination of the sensitivities against IVM by growth curve analysis and time-kill kinetics.

    • Environmental Microbiology
    • Environmental Microbiology, EarlyView. Exposure to particulate matter (PM), a major component of air pollution, is associated with exacerbation of chronic respiratory disease, and infectious diseases such as community-acquired pneumonia. Although PM can cause adverse health effects through direct damage to host cells, our previous study showed that PM can also impact bacterial behaviour by promoting in vivo colonization.

  23. qPCR screening for Yersinia ruckeri clonal complex 1 against a background of putatively avirulent strains in Norwegian aquaculture

    • Journal of Fish Diseases
    • Journal of Fish Diseases, EarlyView. Although a number of genetically diverse Yersinia ruckeri strains are present in Norwegian aquaculture environments, most if not all outbreaks of yersiniosis in Atlantic salmon in Norway are associated with a single specific genetic lineage of serotype O1, termed clonal complex 1. To investigate the presence and spread of virulent and putatively avirulent strains in Norwegian salmon farms, PCR assays specific for Y.

  25. The impacts of biosecurity measures on Campylobacter contamination in broiler houses and slaughterhouses in the Netherlands: A simulation modelling approach

    • Food Control
    • Intestinal campylobacteriosis, caused by Campylobacter ingestion, is the most reported zoonosis in the EU; it is societally costly and can lead to more severe sequelae. To reduce Campylobacter infections, biosecurity measures at both farms and slaughterhouses are warranted. However, the potential improvements achieved by these interventions have not been quantified.
