Sequence and classification of FdPV2, a papillomavirus isolated from feline Bowenoid in situ carcinomas.

Bowenoid in situ squamous cell carcinoma (BISC) is a rare feline skin disorder, which has been described as often associated with papillomavirus infection. It is clinically characterized by solitary or multiple hyperkeratotic plaques affecting older cats. Papillomavirus (PV) sequences amplified from feline viral plaques, and BISC lesions seldom correspond to FdPV1. The goal of the present study was to investigate three cases of BISC and to carry out initial genomic analysis of the associated viral DNA. Samples of skin biopsies taken from three BISC cats were histologically characterized. DNA was extracted and rolling-circle amplification was performed on the skin samples. Restriction enzyme analysis of the amplified DNA revealed the presence of a putative unknown PV. The whole genome was subsequently sequenced and cloned. Alignments with previously described feline PV sequences were carried out and phylogenetic trees were generated. The circular 7,899 base pair sequence of Felis domesticus PV type 2 (FdPV2) contains a typical noncoding region and characteristic open reading frames (ORF) for six putative viral proteins. Phylogenetic analysis based on the nucleotide alignment of L1 genes or the amino acid alignment of E1 proteins of FdPV2 and 52 other PV types indicates that FdPV2 might represent a new genus.

High-pressure structural and vibrational study of PbZr0.40Ti0.60O3.

The high-pressure structure and dynamics of PbZr0.40Ti0.60O3 were investigated by means of neutron diffraction, X-ray diffraction, and resonance Raman spectroscopy. The complex (P4mm, Cm, Cc, F1, F1) phase transition sequence is characterized by these techniques. On the basis of the results of structure refinements, the high-pressure behavior of the spontaneous polarization, the (Zr,Ti)O6 rotation angles, and the polarization rotation angle are obtained. Moreover, resonance Raman spectra combined with previous Raman data in the literature provide evidence that the pressure-induced transition to the monoclinic Cm space group and the above transition sequence terminating in a paraelectric state are general features of Pb(Zr(1-x)Ti(x))O3 (0.48 < or = x < or = 1).

[Cutaneous atypical mycobacteriosis due to Mycobacterium massiliense in a cat]. / Kutane atypische Mykobakteriose durch Mycobacterium massiliense bei einer Katze.

Fast growing mycobacteria are saprophytic bacteria that prevail in water and soil. They are opportunistic pathogens and may cause various infections if gaining entry into the body through a trauma. We herein describe the clinical presentation, pathology and diagnosis of the first case of cutaneous atypical mycobacteriosis due to Mycobacterium massiliense in a cat.

Acute compartment syndrome complicating an intramuscular haemangiosarcoma in a dog.

Acute compartment syndrome in dogs is a rare complication of muscle trauma, but it has not been previously reported as a consequence of neoplasia in dogs. This case report describes the occurrence of a compartment syndrome of the femoral compartment in an 11-year-old, male, mixed-breed dog caused by acute bleeding of an intramuscular haemangiosarcoma. The compartment syndrome was relieved by immediate fasciotomy. The dog was euthanased following acute recurrence of clinical signs seven weeks after surgery.

[Bacteriology and mycology of otitis externa in dogs]. / Bactériologie et mycologie de l'otite externe du chien.

The bacterial and fungal flora of 1118 ears of dogs with otitis externa and 100 ears of healthy control dogs were studied in order to isolate the causative agents. The yeast Malassezia pachydermatis (56%) was by far the most common organism in otitic dogs followed by the bacteria Staphylococcus intermedius (23%), Pseudomonas aeruginosa (12%), Proteus spp. (6%) and Streptococcus canis (5%). A statistical analysis of observed results showed that the incidence of these organisms is significant in otitic dogs. Many strains of S.intermedius, P.aeruginosa and Proteus spp. are resistant to antimicrobial agents commonly used to treat otitis externa. Therefore an antimicrobial susceptibility testing was performed using "Cobas Bact" for these bacterias. Furthermore, 80 strains of M.pachydermatis were submitted to identification-kits (API 20 CAUX, API STAPH, Cobas Micro). The observed results showed that an identification with these tests was not possible.
