The disease is difficult to identify in the early stages of infection. The spores of the different species have different colours and can also cause respiratory damage to humans and other animals. When bee larvae take in spores, they may hatch in the gut, growing rapidly to form a collar-like ring near the larval heads.
Bees infected with CBPV begin to show symptoms after 5 days and die a few days after. [1] Chronic bee paralysis virus infection is a factor that can contribute to or cause the sudden collapse of honeybee colonies. [2] Since honeybees serve a vital role in ecological resilience, it is important to understand factors and diseases that threaten them.
Sacbrood virus or SBV disease is an infectious disease caused by the Morator aetatulas virus that affects honey bee larvae. When sick, the colony declines gradually with few or no replacement workers, costing 20-80% of honey production.
Deformed wing virus (DWV) is a positive-strand [1] RNA virus, one of 22 known viruses affecting honey bees.While most commonly infecting the honey bee, Apis mellifera, it has also been documented in other bee species, like Bombus terrestris, [2] thus, indicating it may have a wider host specificity than previously anticipated.
Malpighamoeba mellificae is a single-celled parasite which affects excretory organs (Malpighian tubules) of adult bees, causing the contagious disease called amoebiasis, which ultimately leads to death of the host. [1] Worker bees are most prone to being infected. It is commonly found in collaboration with nosemosis.
American foulbrood (AFB, Histolysis infectiosa perniciosa larvae apium, Pestis americana larvae apium), caused by the spore-forming bacterium Paenibacillus larvae, [a] is a highly infectious honey bee brood disease. It is the most widespread and destructive of the honey bee brood diseases. It is globally distributed and burning of infected ...
Nosema apis is a microsporidian, a small, unicellular parasite recently reclassified as a fungus that mainly affects honey bees.It causes nosemosis, also called nosema, which is the most common and widespread of adult honey bee diseases. [1]
