“…These field data suggest that A. americanum may play a more primary role in the maintenance and dissemination of the parasite in wild felids. Recent tick transmission studies have indicated that A. americanum may be a more competent vector of C. felis than D. variabilis as in repeated trials the latter was an unsuccessful vector; whereas A. americanum transstadially transmitted the parasite under identical situations (Reichard et al, 2008;Edwards et al, 2010). Additionally, C. felis has only been detected from wild-caught questing A. americanum from Oklahoma (MIR 0.5-1.5%), while there is no report of C. felis from questing D. variabilis (Edwards et al, 2010).…”

“…Cytauxzoon spp. are transmitted by ixodid ticks, and C. felis has been experimentally transmitted by two ticks, Dermacentor variabilis and Amblyomma americanum (Blouin et al, 1984;Kocan et al, 1992;Reichard et al, 2008;Edwards et al, 2010).…”

“…In the USA, bobcats (Lynx rufus) are the natural reservoir hosts for this parasite with high prevalence, but other felids such as Florida panthers (Puma concolor coryi) and domestic cats may also maintain long-term parasitemias and serve as reservoir hosts (SHOCK et al, 2011). Two tick species, Dermacentor variabilis and Amblyomma americanum, are the only known vectors for C. felis in the USA (REICHARD et al, 2009).…”

Cytauxzoon felis and 'Candidatus Mycoplasma haemominutum' coinfection in a Brazilian domestic cat (Felis catus) AbstractThis article describes the first detection of Cytauxzoon felis, using molecular techniques, in a naturally infected domestic cat from Brazil, South America. Coinfection with 'Candidatus Mycoplasma haemominutum' was also found. The molecular identification of the piroplasmid species was performed by Polymerase Chain Reaction (PCR) and sequencing analysis. A 284 pb fragment of the gene encoding the 18S ribosomal RNA region was amplified and showed 99% identity with other C. felis strains from North America. In addition, PCR-RFLP (restriction fragment length polymorphism) analysis, which amplifies a 595 bp fragment of the gene encoding 16S ribosomal RNA of some bacterial species, identified the co-infecting species as 'Candidatus M. haemominutum'.

“…felis Donor Cat. The C. felis donor cat was a survivor from a previous transmission trial in which A. americanum successfully transmitted C. felis (Reichard et al 2009). The donor cat remains persistently and subclinically infected with C. felis since recovering from cytauxzoonosis.…”

“…In an area enzootic for C. felis in Oklahoma, the highest number of cases occurred in May and September (Reichard et al 2008), corresponding to peak activity of Amblyomma americanum adults and nymphs. Laboratory studies have demonstrated both Dermacentor variabilis (Blouin et al 1984) and A. americanum (Reichard et al 2009) as vectors of C. felis to domestic cats. Because the transmission of C. felis to domestic cats has only been attempted twice with D. variabilis and once with A. americanum, in the current study, we further evaluated these ticks as vectors for C. felis.…”

Amblyomma americanum was confirmed as a competent vector in the transmission of Cytauxzoon felis to domestic cats. Infection with C. felis was produced and replicated in four domestic felines by the bite of A. americanum adults that were acquisition fed as nymphs on a domestic cat that survived cytauxzoonosis. Numerous attempts to transmit C. felis with Dermacentor variabilis at the same time were not successful. All cats upon which infected A. americanum were transmission fed exhibited disease typical of cytauxzoonosis, and the eitiologic agent's presence was confirmed. Clinical signs including fever, inappetence, depression, and lethargy were observed beginning 13 d postinfestation. Pale mucus membranes, splenomegaly, icterus, and dyspnea were also observed during the course of the disease. Rectal temperatures of the C. felis-infected principal cats fluctuated from high to subnormal before returning to the normal range. Clinical signs of cytauxzoonsis improved by 24 d postinfestation in all but one cat, with survivors remaining parasitemic and subclinically infected with C. felis. Unengorged A. americanum and D. variabilis were collected from wild habitats to determine the minimum infection rate of C. felis in ticks from an enzootic area. Infection of C. felis was found only in wild-collected A. americanum. The minimum infection rate of C. felis in A. americanum was 0.5% (one of 178) in males, 0.8% (three of 393) in nymphs, and 1.5% (three of 197) in females. We found no wild-collected D. variabilis infected with C. felis. Our results confirm that A. americanum is a primary vector of C. felis.
