Capnocytophaga canimorsus. Brenner et al. 1989. Capnocytophaga canimorsus is a fastidious, slow-growing, Gram-negative rod of the genus Capnocytophaga. [1][2] It is a commensal bacterium in the normal gingival microbiota of canine and feline species, but can cause illness in humans. Transmission may occur through bites, licks, or even close ...
Cat-scratch disease (CSD) is an infectious disease that most often results from a scratch or bite of a cat. [4] Symptoms typically include a non-painful bump or blister at the site of injury and painful and swollen lymph nodes. [2] People may feel tired, have a headache, or a fever. [2]
Eikenella corrodens is a pleomorphic bacillus that sometimes appears coccobacillary and typically creates a depression (or "pit") in the agar on which it is growing. Only half produce the pitting of the agar considered characteristic. [citation needed] It is a slow-growing, facultative anaerobe and a gram-negative bacillus.
Neisseria animaloris, formerly named CDC group EF-4a, is a gram-negative coccoid rod. The bacterium is a commensal of the upper respiratory tract of cats and dogs, and they may cause pulmonary infections in cat. [1] In humans Neisseria animaloris have been reported to cause wound infection after animal bites but also chronic otitis media ...
Cat bites are bites inflicted upon humans, other cats, and other animals by the domestic cat (Latin: Felis catus). [1] [2] Data from the United States show that cat bites represent between 5–15% of all animal bites inflicted to humans, [3] [4] but it has been argued that this figure could be the consequence of under-reporting as bites made by cats are considered by some to be unimportant.
Bartonellosis is an infectious disease produced by bacteria of the genus Bartonella. [1] Bartonella species cause diseases such as Carrión's disease, trench fever, cat-scratch disease, bacillary angiomatosis, peliosis hepatis, chronic bacteremia, endocarditis, chronic lymphadenopathy, and neurological disorders.
New CDC guidance advises taking a common antibiotic within 72 hours after unprotected sexual activity to prevent the spread of sexually transmitted infections (STIs). These new recommendations ...
Gram-negative bacteria are bacteria that, unlike gram-positive bacteria, do not retain the crystal violet stain used in the Gram staining method of bacterial differentiation. [1] Their defining characteristic is their cell envelope, which consists of a thin peptidoglycan cell wall sandwiched between an inner (cytoplasmic) membrane and an outer ...
