“…On the other hand, field studies consistently lend substantiation to the hypothesis that A. americanum is the primary vector for C. felis (Shock et al, 2011). Only wild-caught A. americanum ticks, not D. variabilis , have ever tested positive, via PCR methods, for the presence of C. felis (Reichard et al, 2010; Shock et al, 2011). In western Kentucky, D. variabilis displays two peaks in host-seeking activity – one in May/June and a second in August/September (Burg, 2001).…”

Feline cytauxzoonosis is a rapidly progressing and usually fatal disease in domestic cats caused by the tick-borne pathogen, Cytauxzoon felis. The primary reservoir host for this protozoan parasite is the bobcat (Lynx rufus). In this retrospective study, we have examined the positive cases of feline cytauxzoonosis identified at Murray State University’s Breathitt Veterinary Center, a regional diagnostic facility located in Hopkinsville, Kentucky, between January 2001 and December 2011. Center records reveal that there has been an increase in the rate of diagnosis of domestic feline infection with C. felis over that 10-year span with the majority of cases (75%) occurring between 2006–2011. The infection was diagnosed from March through October and showed a single peak in May, corresponding well with the questing period for the lone star tick, Amblyomma americanum, a known vector of C. felis.

“…2), lending support for A. americanum being the potential primary vector in this area. While the presence of D. variabilis in a geographic region has shown a positive association with an increase in the number of reported cases of C. felis infection, its presence has much less of an impact than that of A. americanum (Shock et al, 2011). …”

“…Genomic DNA was extracted from 100 μl of whole blood using the Qiagen DNA Purification Kit (Germantown, MD) following the manufacturer's protocol. A nested PCR protocol that amplifies the entire internal transcribed spacer (ITS)-1 rRNA region of most piroplasms including Cytauxzoon , Babesia and Theileria species was used to detect C felis as previously described (Bostrom and others 2008, Shock and others 2011). To detect Bartonella species, a PCR protocol that amplifies the internal transcribed spacer (ITS)-1 rRNA region of Bartonella species (Cadenas and others 2008) was used.…”

Risk behaviours exhibited by free‐roaming cats in a suburban US town

et al. 2013

Free-roaming cats may experience numerous hazardous encounters in the outdoor environment, including: vehicular accidents, aggression from other animals and exposure to infectious disease. This research quantitatively examined the outdoor activities of 55 owned cats by monitoring pets outfitted with 'KittyCam' video cameras. KittyCams are a type of Crittercam, designed by National Geographic to allow recording of a cat-eye view without disrupting behaviour. We investigated the activities of free-roaming cats in suburban Athens-Clarke County, Georgia, during all four seasons. Research objectives included documenting the type and regularity of risk behaviours exhibited by free-roaming cats and identifying characteristics of pet cats (eg, age, sex, roaming habitat) which predict risky behaviour in the outdoors. The most common risk behaviours exhibited by suburban free-roaming cats included crossing roads (45 per cent of our sample), encountering strange cats (25 per cent), eating and drinking substances away from home (25 per cent), exploring storm drain systems (20 per cent), and entering crawlspaces of houses (20 per cent). Male cats were more likely to engage in risk behaviours than female cats, and older cats engaged in fewer risk behaviours than younger individuals. We hope this information can be used to encourage the public to keep cats indoors more often (with consideration for their indoor quality of life) or supervise them while outdoors.

“…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'.
