Abstract:
ABSTRACT Three hemotropic mycoplasmas have been identified in pet cats: Mycoplasma haemofelis, “Candidatus Mycoplasma haemominutum,” and “Candidatus Mycoplasma turicensis.” The way in which these agents are transmitted is largely unknown. Thus, this study aimed to investigate fleas, ticks, and rodents as well as saliva and feces from infected cats for the presence of hemotropic mycoplasmas, to gain insight into potential transmission routes for these agents. DNA was extracted from arthropods and from rodent blood or tissue samples from Switzerland and from salivary and fecal swabs from two exp

Abstract:
Cytauxzoon felis is a hemoparasite capable of infecting domestic and wild cats. Studies suggest that wild cats are the main reservoirs of the protozoan, and transmission occurs through the bite of an infected tick. Hemotropic mycoplasmas are Gram-negative bacteria responsible for severe hemolytic anemia. The feline immunodeficiency virus (FIV) is a retrovirus capable of generating immunosuppression in the host and persistent infection. The present work describes a case of co infection of Cytauxzoon felis, Mycoplasma haemofelis, and feline immunodeficiency virus (FIV) in a cat. A feline from th

Abstract:
ABSTRACTMycoplasma haemofelisinfection frequently causes anemia in cats. Despite an intense immune response and/or antibiotic treatment, cats often remain asymptomatic carriers following infection. Our hypothesis is that detection of antibodies toM. haemofelisis a sensitive approach for identifying infected cats, particularly carriers. To date, no immunoassay has been developed. This is due largely to the inability to cultureM. haemofelis in vitro; hence, a source of antigen is not readily available. The objective of this study was to identify, express, and purify immunogenic proteins ofM. hae

ABSTRACT In felids, three hemotropic mycoplasma species (hemoplasmas) have been described: Mycoplasma haemofelis, “Candidatus Mycoplasma haemominutum,” and “Candidatus Mycoplasma turicensis.” In particular, M. haemofelis may cause severe, potentially life-threatening hemolytic anemia. No routine serological assays for feline hemoplasma infections are available. Thus, the goal of our project was to identify and characterize an M. haemofelis antigen (DnaK) that subsequently could be applied as a recombinant antigen in a serological assay.

Ao atingir o sistema circulatório do felino, o parasita se adere as hemácias, gerando resposta imune do hospedeiro levando a quadros de anemia hemolítica. Alguns felinos costumam ter anemia regenerativa como achado laboratorial devido a parasitemia causada pelo microrganismo, exceto em gatos positivos para FeLV.
