Actinobacillus is a genus of Gram-negative, nonmotile and non-spore-forming, oval to rod-shaped bacteria occurring as parasites or pathogens in mammals, birds, and reptiles. [1] It is a member of the family Pasteurellaceae. [2]

The organisms of the genus Actinobacillus are small, gram-negative, nonmotile, nonsporing bacilli, and coccobacilli. They are often interspersed with coccal elements. They are aerobic, microaerophilic, or facultatively anaerobic, fermenting carbohydrates with the production of …

Actinobacillosis is caused by several species of gram-negative coccobacilli of the genus Actinobacillus. Clinical signs vary, depending on the specific bacteria and the animal species they infect. Diagnosis can be confirmed by culture, PCR, or ELISA of tissue samples to identify the bacteria. Antibiotics are the usual treatment in swine and horses.

Actinobacillus species are Gram-negative bacteria responsible for several quite distinct disease conditions of animals. The natural habitat of the organisms is primarily the upper respiratory tract and oral cavity.

Actinobacillus spp. are commensals and pathogens of cattle and humans. Three species, A. equuli, A. suis, and A. ligneresii, can infect animal bites. Actinobacillus actinomycemcomitans is found in the mouth as part of the normal flora and is …

Actinobacillus and Aggregatibacter Species. Actinobacillus and Aggregatibacter species are coccoid to small gram-negative bacilli in the family Pasteurellaceae. These organisms are normal microbiota of the oral cavity in humans.

Actinobacillus ureae (A. ureae) is an unusual commensal of human respiratory flora, rarely causing human infection. The predisposing factors, identification, clinical features, and antibiotic therapy of A. ureae are seldomly reported.

SUMMARY. Actinobacteria are Gram-positive bacteria with high G+C DNA content that constitute one of the largest bacterial phyla, and they are ubiquitously distributed in both aquatic and terrestrial ecosystems. Many Actinobacteria have a mycelial lifestyle and undergo complex morphological differentiation. They also have an extensive secondary metabolism and produce …

Actinobacillosis is a zoonotic disease caused by Actinobacillus. [1] It is more commonly associated with animals than with humans. [2] One of the most common forms seen by veterinarians is mouth actinobacillosis of cattle, due to Actinobacillus lignieresii.
