Canine Anaplasmosis
Canine Anaplasmosis Andy Pachikerl, Ph.D Introduction Anaplasma platys (formerly Ehrlichia platys) is a Gram negative, non-mobile, pleomorphic bacterium, belonging to the Anaplasmataceae family, which has been speculated, but not conclusively demonstrated, to be transmitted by Rhipicephalus sanguineus, known as the “brown dog tick” (Simpson et al. 1991). Anaplasma platys is an obligate intracellular […]

Chlamydophila felis: A Unique Bacteria Causing Diseases to Felines Maigan Espinili Maruquin Structure and Replication The chlamydiae is unique obligate intracellular bacteria. The Chlamydophila felis is a Gram- negative and rod- shaped coccoid bacterium however the cell wall lacks peptidoglycan (Gruffydd-Jones, Addie et al. 2009). It has two morphologically distinct structures. The (1) […]

This in turn cause severe lung disease, heart failure […]
A Review on Feline Calicivirus
Maigan Espinili Maruquin Structure and Replication The Caliciviruses are small, non-enveloped, positive strand RNA viruses which infects a wide range of hosts (Sosnovtsev and Green 2003), which, in cats, feline calicivirus- (FCV) is associated with upper respiratory tract infections (Gaskell, R. M., 1985). The FCV is a naked and icosaedral virus, 30–40 nm in diameter […]
Canine blood-typing
Canine blood-typing Andy Pachikerl, Ph.D Introduction: Dog erythrocyte antigens are responsible for initiating approximately 70% to 80% of immune-mediated transfusion reactions in the dog. As with other species, the red blood cell antigens found in the dog have various immunogenicities. In health, these antigens are participants in cell recognition-self versus nonself. In disease, […]

Case study: Cerebral toxoplasmosis in a cat with feline leukemia and feline infectious peritonitis viral infections Robert Lo, Ph.D, D.V.M A diarrheic young cat died because of severe multifocal meningoencephalitis caused by Toxoplasma gondii. Protozoan cysts and tachyzoites in the brain were confirmed by immunohistochemical staining. Coinfection of feline leukemia virus (FeLV) and […]
