Streptococcus canis is a group G beta-hemolytic species of Streptococcus. [1] It was first isolated in dogs, giving the bacterium its name. These bacteria are characteristically different from Streptococcus dysgalactiae, which is a human-specific group G species that has a different phenotypic chemical composition.
Members of the genus Capnocytophaga are found in the oral cavities of humans and animals. Most of these species are not found in humans. [4] C. canimorsus is a commensal bacterium found in dogs and cats; it is not a member of the normal microbiota of humans. About 26% of dogs carry these commensal bacteria in their mouths.
The high frequency of strains producing beta-lactamase limit the use of single beta-lactam antibiotics as first-line treatment, which underlies the need to test the in vitro susceptibility of clinical isolates. Many antimicrobial treatments were used despite a lack of randomized trials and guidelines relating to the duration of treatment ...
Kennel cough is so named because the infection can spread quickly among dogs in the close quarters of a kennel or animal shelter. Viral and bacterial causes of canine cough are spread through airborne droplets produced by sneezing and coughing. These agents also spread through contact with contaminated surfaces.
Dogs are ten times more likely to be infected than humans. The disease in dogs can affect the eyes, brain, lungs, skin, or bones. [15] Histoplasmosis* is a fungal disease caused by Histoplasma capsulatum that affects both dogs and humans. The disease in dogs usually affects the lungs and small intestine. [16]
The host range of the bacterium is mainly domestic dogs but evidence of infections in foxes and coyotes has been reported. [9] B. canis is a zoonotic organism [10] and although rare, humans can contract the infection. It is unlikely, but most common in dog breeders, those in laboratories dealing with the bacteria, or people who are ...
Streptococcus dysgalactiae is a gram positive, beta-haemolytic, coccal bacterium belonging to the family Streptococcaceae.It is capable of infecting both humans and animals, but is most frequently encountered as a commensal of the alimentary tract, genital tract, or less commonly, as a part of the skin flora.
E. canis is a small, coccus bacterium with a single circular chromosome.Minute in size, E. canis is smaller than the other species in the genus Ehrlichia. [8] [10]The cell walls of this organism lack peptidoglycans and lipopolysaccharides typically present in at least small amounts in most other Gram-negative bacteria, which is believed to contribute to its ability to resist the immune ...
