Sacbrood viruses and select Lake Sinai virus variants dominated colonies symptomatic for European foulbrood.

European foulbrood (EFB) is a prevalent disease in the European honey bee () in the United States, which can lead to colony decline and collapse. The bacterial components of EFB are well-studied, but the diversity of viral infections within infected colonies has not been explored. In this study, we use meta-transcriptomics sequencing of 12 honey bee hives, symptomatic (+, = 6) and asymptomatic (-, = 6) for EFB, to investigate viral infection associated with the disease.

No impact of hygienic behavior and viral coinfection on the development of European foulbrood in honey bee (Apis mellifera) colonies during blueberry pollination in Michigan.

European foulbrood (EFB) is a severe disease of honey bee (Apis mellifera) larvae caused by the bacterium Linnaeus [Hymenoptera: Apidae]) Melissococcus plutonius (ex White) Bailey and Collins (Lactobacillales: Enterococcaceae). Many beekeepers in North America report severe EFB following blueberry pollination, but it is not clear what factors during pollination are related to clinical disease. Additionally, the impact that other factors such as viral load and hygienic behavior have on EFB has not been studied.

Northward Expansion of Amblyomma americanum (Acari: Ixodidae) into Southwestern Michigan.

Amblyomma americanum (Linnaeus) (Acari: Ixodidae) (lone star tick) is an aggressive, generalist parasite that vectors numerous important human and animal pathogens. In recent decades its geographic range has expanded northwards from endemic regions in the southeastern and southcentral United States. In 2019 five questing A.

Validation of Diagnostic Methods for European Foulbrood on Commercial Honey Bee Colonies in the United States.

One of the most serious bacterial pathogens of Western honey bees (Apis mellifera Linnaeus [Hymenoptera: Apidae]) is Melissococcus plutonius, the cause of the disease European foulbrood. Because European foulbrood is highly variable, with diverse outcomes at both the individual and colony levels, it is difficult to diagnose through visual inspection alone. Common lab diagnostic techniques include microscopic examination and molecular detection through PCR.

Antimicrobial-resistant non-typhoidal prevalence among poultry farms and slaughterhouses in Chitwan, Nepal.

Background And Aim: Antibiotic-resistant infections are one of the leading threats to public health globally. Indiscriminate use of antibiotics in food animal production is an important driver of resistance, particularly among foodborne pathogens such as non-typhoidal (NTS). While there has been extensive research on antimicrobial-resistant (AMR) in India and China, there have been few studies in countries in South Asia, including Nepal.

Prevalence of non-typhoidal and risk factors on poultry farms in Chitwan, Nepal.

Background And Aim: Poultry is becoming an increasingly important source of protein in the Nepalese diet. The Chitwan region of Nepal is the hub of the emerging poultry industry. Little is known about the prevalence of non-typhoidal (NTS) on poultry farms or the role of farm management practices that may contribute to the presence of NTS on farms.
