Chloroquine (CQ) then becomes protonated (to CQ 2+), as the digestive vacuole is known to be acidic (pH 4.7); chloroquine then cannot leave by diffusion. Chloroquine caps hemozoin molecules to prevent further biocrystallization of heme, thus leading to heme buildup. Chloroquine binds to heme (or FP) to form the FP-chloroquine complex; this ...
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.
In dogs it is most commonly caused by mechanical irritation (such as by entropion, ectropion, or trichiasis), allergies, and keratoconjunctivitis sicca. Any bacterial infection is usually secondary. [72] Eye proptosis is a condition resulting in forward displacement and entrapment of the eye from behind by the eyelids. It is a common result of ...
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.
In biofilm-associated infections, quinolones exhibit a good ability to penetrate the biofilm and target bacteria within it, especially during the early stages of biofilm formation. Their antibiofilm activity is generally higher than that of old beta-lactams and glycopeptides but remains lower compared to antibiotics such as tetracyclines ...
The two major bacterial pathogens are Anaplasma marginale and Anaplasma phagocytophilum. [3] These microorganisms are Gram-negative, [ 4 ] and infect red blood cells . [ 5 ] Once the host is infected with anaplasmosis, the immune system will try to fight off and kill the infected red blood cells, but will also kill healthy red blood cells. [ 2 ]
Katerina Nash, a Czech athlete who has competed in five different Olympics as a cyclist and cross-country skier, avoided a four-year doping ban after the USADA determined a positive test for a ...
A scanning electron micrograph depicted a number of Gram-negative Bordetella bronchiseptica bacteria. In veterinary medicine, B. bronchiseptica leads to a range of pathologies in different hosts. It is a serious disease of dogs, pigs, and rabbits, and has been seen in cats, horses, and seals. A PCR test for the pathogen exists. [8]
