Infectious bovine keratoconjunctivitis Kristjan Rannaäär Veterinary medicine, 2. year, 2. group Abstract Infectious bovine keratoconjunctivitis (IBK) is a highly contagious ocular disease and big problem in cattle farms worldwide. It is the most common ocular disease of cattle caused by bacteria Moraxella bovis. This study focuses on IBK despite having low mortality rate and complete recovery, it causes significant loss of productivity in the herds affected due to the costs of treatment and considerable impact on afflicted animals, including blindness. This research is focused on the details, such as risk factors, pathogenesis, etiology, clinical signs prevention, transmission, and treatment, which animal handlers should be aware of to minimize the harm caused by IBK. Vaccination does not ensure lifelong immunity and not prevent a primary and reinfection of the cattle. Therefore, it is necessary to keep the cattle in a healthy body condition to assure a high immunity level,

Skin may be cool to touch but to the user may feel warm or normal, profuse sweating may accompany alcohol use. Loose muscle tone, lose of fine motor coordination,odor of alcohol on the breath,a
