Evaluation Of Residual Antibacterial Effects On Canine Skin Surface And Hairs Following Treatment With Five Commercial Mousse Products Against Staphylococcus Pseudintermedius In Vitro, Chi-Yen Wu

LSU Master's Theses

Topical products are essential treatments for canine superficial bacterial folliculitis. However, studies for commercial products typically evaluate antibacterial effects on hairs rather than the skin surface. In addition, the interference from the hair length has not been evaluated in these studies. Therefore, the study objective for this study was to evaluate the residual antibacterial effects of five mousse products, (1) 2% chlorhexidine and 2% miconazole, (2) 0.05% phytosphingosine, (3) 2% salicylic acid and 10% ethyl lactate, (4) 3% chlorhexidine and 0.5% climbazole, and (5) 2% chlorhexidine and 1% ketoconazole on both the skin surface and hairs in both short- and …

Complete Genome Sequences Of Three Staphylococcus Pseudintermedius Strains Isolated From Botswana, Mohamed Adel Salaheldin Abouelkhair, Stephen A. Kania, David A. Bemis, Matthew C. Riley, Riley Thompson

Faculty Publications and Other Works -- Biomedical and Diagnostic Sciences

We report here the first whole-genome sequences for 3 strains of Staphylococcus pseudintermedius (112N, 113N, and 114N) isolated in Africa. Samples of this opportunistic pathogen were collected from nasal swabs obtained from healthy carrier dogs in Botswana. The sequence information will facilitate spatial phylogenetic comparisons of staphylococcal species and other bacteria at the genome level.

Complete Genome Sequence Of Staphylococcus Pseudintermedius Type Strain Lmg 22219, Mohamed Adel Salaheldin Abouelkhair, Stephen Kania, D A. Bemis, Matthew C. Riley

Faculty Publications and Other Works -- Biomedical and Diagnostic Sciences

We report the first complete genome sequence of LMG 22219 (=ON 86T = CCUG 49543T), the Staphylococcus pseudintermedius type strain isolated from feline lung tissue. This sequence information will facilitate phylogenetic comparisons of staphylococcal species and other bacteria at the genome level.

Staphylococcus Pseudintermedius: Population Genetics And Antimicrobial Resistance, Ricardo Videla

Masters Theses

Staphylococcus pseudintermedius is a Gram-positive coagulase-negative coccus. It is a normal inhabitant of the skin of dogs. However, clinical disease can be observed in animals that are immunossuppressed or if the skin barrier is altered. This bacterium is recognized as the main cause of canine pyoderma and has also been associated with other conditions such as infection of the urinary tract, the ears, and surgical wounds.

Methicillin resistance and resistance to other antimicrobials regularly used by veterinarians is common among S. pseudintermedius which can complicate treatment. The first report of mecA, gene responsible for methicillin resistance, in S. pseudintermedius …

Methicillin Resistance In Staphylococcus Pseudintermedius, Chad Christopher Black

Doctoral Dissertations

Staphylococcus pseudintermedius affecting dogs is analogous to S. aureus on humans, acting as both normal flora and opportunistic pathogen. Methicillin resistance in S. pseudintermedius is recent, with the first documented occurrence of an isolate bearing the methicillin resistance gene, mecA, in 1999. This gene encodes penicillin binding protein 2a, which renders all beta-lactam drugs ineffective and functions as a “gateway” antibiotic resistance determinant. In the presence of ineffective antibiotics, opportunities for mutational events and acquisition of mobile genetic elements increase as microbial densities increase, often leading to multi-drug resistance. Methicillin-resistant S. pseudintermedius (MRSP) infections have become increasingly common. For …
