Megabac S is a unique water soluble formulation of Amphotericin B. Megabac S has proven effectiveness against Megabacteria in caged and aviary birds.

Ingredients: Water soluble Amphotericin-B

Guaranteed Analysis: Amphotericin-B - 2%

Dose Rate - Mix 250 mg in 50 mLs of distilled or purified water.
Treat for 10 days.
40g treats 230 budgies for 10 days

The active within Megabac S is not absorbed from the gut, nor does it affect the normal gut flora of the bird. Therefore treatment of the affected bird is completely safe.

Diagnosis of Megabacteria may be difficult. Not all infected birds shed the organism in their droppings, so false negative tests do occur. The most accurate method of diagnosis is the Gram stain of the proventricular mucosa at necropsy. Avian veterinarians and pathology laboratories can perform this test.

Treatment time is normally 10 days, during this time no other water source should be offered. For treatment in wet cold or foggy weather, birds must be housed indoors. Treated water should be changed daily. Protect treated water from sunlight If a particular bird is not consuming the expected amount of water ( 6 mLs per 100 gm Body Weight ) then the concentration of the medication must be increased accordingly.

When treating any disease, hygiene and disinfection are critical to the treatment success. All cages and aviaries should be thoroughly cleaned and disinfected with Avi- Safe during the treatment period.

Storage & Availability: Megabac S must be stored in the original Vetafarm air tight container at less than 25°C. Avoid exposure of the powder to light for extended periods. Best if kept in refrigerator..
