INTRODUCTION Honey bees weren’t on veterinarians’ radars until the U.S. Food and Drug Administration issued a final Veterinary Feed Directive (VFD) rule, effective January 1, 2017, that classifies honey bees as livestock and places them under the provisions of the VFD. As a result of that rule and changes in the FDA’s policy on medically important antimicrobials, honey bees now fall into the veterinarians’ purview, and veterinarians need to know about their care. -

American Foulbrood Identification and Management
American foulbrood identification and management November 2020, Primefact 209, Fourth edition Plant Biosecurity and Product Integrity, Tocal American foulbrood (AFB) disease is the most serious brood disease of honeybees in NSW. It is caused by the bacterium Paenibacillus larvae. AFB has been found in all states and territories in Australia. AFB is a notifiable disease under the NSW Biosecurity Act 2015. There is a persistent low level of infection in NSW and some evidence it is increasing. Early and accurate diagnosis of this disease is essential if control is to be effective. Figure 1 When the larva first dies the diseased material ropes or strings out when touched with a Examining brood match. Honeybee colonies must be carefully examined for disease several times each year. Brood should be thoroughly examined for AFB at least twice a year, in spring and autumn as a minimum. Remove each brood comb from the colony and shake or brush most of the bees into the box, or at the entrance, leaving the comb clear for examination. Hold the comb by the top bar, at such an angle that the light reaches the base of Figure 2 As the ropy mass dries out it forms a hard the cells being examined. scale (this image is looking into the bottom of cells with top bar closest to viewer). Examine each comb in a regular pattern, so all areas of the comb are thoroughly checked.

Nosema Disease Information for Identification & Control in New York
NYS$ Nosema Disease BEEKEEPER! TECH!TEAM! information for identification & control in New York What is Nosema? Nosema is one of the most prevalent infections in honey bees in New York. It is caused by two species of fungal gut parasites, Nosema apis and Nosema ceranae. Both parasites can kill colonies that are unable to clear the infection. Bees become infected when they ingest Nosema spores. The disease is spread fecal-orally, through food sharing, grooming, sexual transmission, and by cleaning contaminated cells. Once spores are consumed, they travel to the intestine where they become infectious. Nosema ceranae is by far the most prevalent species of Nosema found in New York State. Many institutions in the US and Canada recognize the treatment threshold as 1 million spores/bee, yet this threshold is not well established for Nosema ceranae. Beekeepers who wish to treat their colonies should use this current threshold until further research can determine a more reliable one. What are the symptoms? Symptoms include reduced honey production, slow spring build up, dwindling adult population, and reduced brood production. Other than these general effects, colonies infected with Nosema are often asymptomatic. Dysentery is not a reliable symptom, as it does not occur with Nosema ceranae. In colonies that die from the disease, most adults die far from the hive. Inside the hive, there may be a few dead bees on the bottom board and only some young bees and the queen remaining. Dwindling and reduced brood production (left) are symptoms. Dysentery (right) is not a reliable symptom. Preventing Nosema • Manage strong colonies that are not stressed from other causes, and ensure good nutrition • Replace the 2 oldest frames in each hive body with foundation every year to reduce spore accumulation • Decontaminate equipment from infected colonies before reusing. -

American Foulbrood (Afb)
AMERICAN FOULBROOD (AFB) Description American Foulbrood (AFB), Paenibacillus larvae, is an infectious and contagious bacterial disease of honey bee larvae. AFB is introduced and spread by spores carried on drifting bees from nearby colonies, infected comb, used equipment, tools, beekeepers, and robbing. The infection is initiated when spores enter the colony and then nurse bees feed contaminated spores to developing larvae. Note that spores are only infectious to larvae and do not present symptoms in adult bees. The spores then migrate to the midgut, germinate and become vegetative allowing the bacteria to consume the larvae causing death. Typically, larval death occurs after the cells are sealed. The dark colored AFB scale that results from dead, dried larvae is very hard for workers to remove allowing colonies to be continually infected if using contaminated equipment. AFB scales contain millions of spores allowing ease of transmission within and between colonies. Given this, AFB is highly contagious and can spread rapidly becoming lethal for infected colonies, as such is considered a major threat to apiculture. Signs and Symptoms May see colony worker population decline May have an agitated and/or aggressive colony Foul, rotting smell (compared to rotting meat or sulfurous chicken house) Uneven and/or spotty brood pattern on frame(s) Perforated, greasy and/or darkened sealed brood cell capping(s) Sunken sealed brood cell capping(s) Moisture on top of sealed brood capping(s) Coffee brown colored larvae located at the bottom of the cell Roping, sticky larval remains at least 2cm in length when drawn out of cell Coffee brown to black colored larvae hardened into dark "scales", located at the bottom of cells that are difficult to remove and may fluorescence when shined upon using UV light source Coffee brown colored dead pupae with protruding tongue Think You May Have AFB?
