PST 06107 Basic Veterinary Pharmacology Session 4: Pharmacotherapy of Anthrax and Aspergillosis in Cattle and Goat Learning Tasks By the end of this session students are expected to be able to: Define Anthrax and Aspergillosis in Cattle and Goat List signs and symptoms of Anthrax and Aspergillosis in Cattle and Goat Describe pharmacological treatment of Anthrax and Aspergillosis in Cattle and Goat Describe dose, dosage and course of drugs used to treat Anthrax and Aspergillosis in Cattle and Goat List contraindications of drugs used to treat Anthrax and Aspergillosis in Cattle and Goat List common side effects and adverse effects of drugs used to treat Anthrax and Aspergillosis in Cattle and Goat Describe Control and Prevention of Anthrax and Aspergillosis in Cattle and Goat Activity: Buzzing What is Anthrax? ? Definition of Anthrax and Aspergillosis in Cattle and Goat Anthrax Anthrax is an acute, febrile (42 o C), septicemia , fatal bacterial disease of food animals caused by Bacillus anthracis Anthrax outbreak occurs irregularly and is commonly associated with neutral or alkaline, calcareous soils where the spores revert to the vegetative form and multiply to infectious levels if environmental conditions of soil, moisture, temperature, and nutrition are optimal Signs and Symptoms of Anthrax in Cattle and Goat The following are the signs and symptoms of Anthrax Acute illness is characterized by abrupt onset of; F ever , S igns of abdominal pain, T rembling , H ematuria , and blood-tinged diarrhea . Signs and Symptoms of Anthrax in Cattle and Goat Pregnant animals may abort Milk production in lactating animals often decline or is tinged with blood. Ventral subcutaneous edema may be present followed by death. Chronic infection is rare in cattle and is manifested by localized edematous swelling on the ventral neck, thorax, and shoulders. Areas most frequently involved are the ventral neck, thorax, and shoulders . Pharmacological Treatment of Anthrax in Cattle and Goat Indicated drugs Penicillin 22,000 IU/kg, IM, q 12 h for 2 days, then daily for 3 days or Benzathine q 48-72 h; or Oxytetracycline 6-11 mg/kg, IM or IV, q 12-24 h or Amoxicillin 5-10 mg/kg q 24 h for 3-5 days or Pharmacological Treatment of Anthrax in Cattle and Goat Cont … Ciprofloxacin 2.8 mg/kg, IV or PO, q 8 h for 4 days or Doxycycline, 20 mg/kg, IV Note: among the tetracyclines , doxycycline is highly lipophilic thus penetrates tissue with ease, is more completely absorbed & slowly excreted, or Erythromycin 12.5 mg/kg (adult), IM, IV or SC; 15-30 mg/kg (calves), IM, IV, or SC, or Dihydrostreptomycin or streptomycin, 10 mg/kg, q 12h IM, SC; Pharmacological Treatment of Anthrax in Cattle and Goat Cont … Contraindications Penicillins ; In animals with hypersensitivity reactions to penicillins Oxytetracyclines in animals with Renal impairment, Pregnant animals and up to 4 weeks of age in neonates. Erythromycin base in animals with impaired liver function Streptomycin or dihydrostreptomycin sulphate is contraindicated to myasthenia gravis Common Side Effects and Adverse Drug Reactions of Drugs Used in Treatment of Anthrax in Cattle and Goat Oxytetracycline Gastrointestinal symptoms are more severe with oxytetracycline among the tetracycline Discoloration of the teeth when used during pregnancy Streptomycin or dihydrostreptomycin sulfate Nephrotoxicity Ototoxicity Neuromuscular blockage At higher dosage calves may develop diarrheal Common Side Effects and Adverse Drug Reactions of Drugs Used in Treatment of Anthrax in Cattle and Goat Cont …. Ciprofloxacin Lameness and severe pain in some immature animals due to damage to weight-bearing joints when used at therapeutic doses in some immature animals. Activity: Brainstorming What are the prevention and control measures for Anthrax? Prevention and Control of Anthrax in Cattle and Goat Cut off infection source Moving other animals away from the affected area is an important early action. Vaccination Animals should not be vaccinated within 2 months of anticipated slaughter Antibiotics should not be administered within 1 wk of vaccination Animals that have died of anthrax should be burned in a closed incinerator Public health significance Anthrax is highly pathogenic to humans; thus care should be taken during handling of suspected cases For pharmacotherapy of Aspergillosis, REFER Students to Handout 4.1: Pharmacotherapy of Aspergillosis in Cattle and Goat Key Points Anthrax is an acute infectious disease caused by bacteria called Bacillus anthracis . The anthrax bacterium produces spores (small resistant cells) which are capable of surviving for many years in the environment Anthrax may present as cutaneous, inhalational or intestinal anthrax Treatment with antibiotics is essential, particularly for inhalational anthrax Control of anthrax in livestock herds is essential for prevention of its spread to humans Evaluation What is anthrax? What are the common signs and symptoms of anthrax in cattle and goat? What is the pharmacological treatment of anthrax in cattle and goat? References Riviere J. E., Papich M. G. (2009).
