In international literature, the disease is commonly referred to as haemorrhagic septicaemia or hemorrhagic septicemia. Some international references have reported that serotype B:2 is associated with many outbreaks in Asia. However, the strain circulating in each locality should be confirmed through epidemiological surveillance or professional testing.<\/span><\/p>\n<p><i><span style=\"font-weight: 400;\">Pasteurella multocida<\/span><\/i><span style=\"font-weight: 400;\"> may be present asymptomatically in the upper respiratory tract of healthy cattle and buffaloes. When an animal\u2019s immune resistance is weakened due to stress, sudden weather changes, or transportation, the bacteria may multiply rapidly and cause disease.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The disease can occur in many cattle and buffalo production areas, especially when weather, environmental conditions, and herd resistance create conditions favorable for disease outbreaks. Farmers should follow disease alerts, vaccination plans, and prevention recommendations issued periodically by local animal health authorities.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In many localities, hemorrhagic septicemia in cattle and buffaloes may be included in regular vaccination plans or disease prevention programs guided by animal health authorities.

This can reduce the risk of disease and disease severity if infection occurs.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">However, a vaccine is not an \u201cabsolute guarantee.\u201d Animals may still become sick if they are exposed to a large bacterial load, if vaccination is not performed correctly, or if their resistance is too weak.

If abnormal signs occur, contact a veterinarian for handling guidance.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">If an animal shows abnormal reactions such as prolonged high fever, difficulty breathing, or generalized itching, contact a veterinarian immediately.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Keep complete records: vaccination date, vaccine type, batch number, and post-vaccination reactions.

Incorrect dosage or technique may reduce vaccine effectiveness or cause adverse events.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Hemorrhagic septicemia vaccines need to be kept cold throughout transport and storage. A broken cold chain may make the vaccine ineffective without any visible external sign.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">According to recommendations from many manufacturers, protective immunity generally tends to develop around 2\u20133 weeks after completion of the vaccination course. This is not an emergency measure after an outbreak has already occurred, and the specific timing may vary depending on vaccine type.<\/span><\/li>\n<\/ul>\n<h2><b>What to Do When Hemorrhagic Septicemia Is Suspected or an Outbreak Occurs<\/b><\/h2>\n<h3><b>Immediate Steps<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">When one or more animals in the herd show signs suggestive of hemorrhagic septicemia, the priority steps are:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Immediately isolate the suspected animal from the herd by moving it to a separate area and limiting contact with other animals.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Report immediately to the local veterinary officer, local animal health authority, or specialized unit assigned in the locality.

Carcasses should be handled according to veterinary guidance, usually through controlled burial or incineration under veterinary supervision.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Disinfect immediately the area where the sick animal stayed and any equipment that came into contact with it.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Monitor the whole herd after detection of a suspected case. Record temperature, behavior, feed intake, and abnormal signs to provide to the veterinarian when needed.<\/span><\/li>\n<\/ul>\n<h3><b>The Role of Veterinarians in Outbreak Handling<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">When a veterinarian confirms a case, they will provide guidance on:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Treatment protocols for sick animals, when appropriate, usually involving antibiotics specifically prescribed by the veterinarian based on each animal\u2019s condition and current recommendations.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Whether emergency vaccination is needed for animals that are not infected.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Cleaning, disinfection, and surveillance procedures for the entire area.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Farmers should never buy antibiotics and treat animals on their own without prescription.

However, respiratory transmission from cattle or buffaloes to humans under normal farming conditions is very rare.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Even so, people with open wounds should limit direct contact with sick animals and wear protective equipment when handling outbreak areas. If injured while contacting sick animals, they should visit a healthcare facility for advice.<\/span><\/p>\n<h3><b>Can Cattle Still Get Hemorrhagic Septicemia After Vaccination?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Vaccines help reduce the risk of disease and disease severity if infection occurs, but they do not guarantee 100% protection. Protective effectiveness depends on vaccine quality, injection technique, storage conditions, and each animal\u2019s resistance.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This is why disease prevention should combine vaccination with other management measures.<\/span><\/p>\n<h3><b>How Often Should Cattle and Buffaloes Receive Booster Vaccination Against Hemorrhagic Septicemia?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">The booster schedule for hemorrhagic septicemia vaccines depends on vaccine type, manufacturer instructions, herd health status, and the local disease prevention plan. Farmers should ask the responsible veterinarian to determine the appropriate booster timing instead of applying one general schedule for all herds.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The specific vaccination schedule should be confirmed with the responsible veterinarian and based on the vaccine manufacturer\u2019s instructions.<\/span><\/p>\n<h3><b>Can Pregnant Cows Be Vaccinated Against Hemorrhagic Septicemia?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Some hemorrhagic septicemia vaccines are inactivated vaccines, but farmers should not assume that every vaccine is suitable for pregnant cows. Before vaccination, they should check the exact vaccine type, read the manufacturer\u2019s instructions, and ask a veterinarian about the appropriate timing, especially during sensitive stages of pregnancy.<\/span><\/p>\n<h3><b>How Should Housing Be Cleaned and Disinfected After a Hemorrhagic Septicemia Outbreak?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">After a confirmed or suspected outbreak, mechanical cleaning, proper waste collection, and disinfection of animal housing should be carried out using lime powder or approved veterinary disinfectants, according to product label instructions and veterinary guidance.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">All equipment and vehicles that have contacted sick animals should also be cleaned and disinfected.
