Keratomycosis in a dog treated with topical 1% voriconazole solution.

A 2-year-old Jack Russell Terrier was presented for treatment of a worsening corneal ulcer and keratomalacia following removal of a vegetative foreign body. The keratomalacia responded to topical gentamicin therapy; however, the eye became suddenly painful and at examination two areas of increased opacity had developed. Fungal keratitis was demonstrated by corneal scrape showing branching, septate fungal hyphae.

Two species of canine Babesia in Australia: detection and characterization by PCR.

The haemoprotozoan Babesia canis has been recognized in Australia for many years, and a second, smaller species has recently been discovered. Amplification and sequencing of a partial region of the 18S small subunit ribosomal RNA (rRNA) gene enabled detection and characterization of the large and small canine babesiae of Australia for the first time. Isolates from northern Australia were genetically characterized to be 99% homologous to Babesia canis vogeli, confirming previous speculation about the subspecies of B.

Babesia gibsoni infection in three dogs in Victoria.

Small intraerythrocytic parasites were observed in the blood of three related male American Pit Bull Terriers. Two of the dogs, both less than 1-year-old, were anaemic at the time of initial examination and the third, an adult and sire of the two younger dogs, had a normal haemogram and low parasitaemia. The morphological appearance of the erythrocyte inclusions, analysis of a 450-bp region of the 18S rRNA gene and antibody titres provided evidence that this parasite was Babesia gibsoni, a species not previously reported in Australia.
