“…Thus, a significant difference in the prevalence of strong or moderate biofilm production was observed between mammalian-origin MR and MS CoNS (P < 0.001, independent t test). This finding differs from observations on MR and MS Staphylococcus pseudintermedius isolated from companion dogs in Republic of Korea, indicating no difference of biofilm-producing abilities between MR and MS S. pseudintermedius [16]. In birds, 96.4% (54/56) CoNS could form biofilm regardless of methicillin resistance, and 62.5% (35/56) of the CoNS demonstrated strong or moderate biofilm production ability.…”

“…Most of the CoNS isolated from wild animals were capable of biofilm production, with 65.1% being classified as either strong or moderate biofilm producers. This data indicates relatively lower prevalence of biofilm producing CoNS in wild animals than in companion animals [16–18]. However, considering that all wild animals evaluated in this study seem to have no prior exposure to antibiotic therapy, this prevalence indicates a wider spread of the biofilm-producing bacteria in the environment.…”

Biofilm production is a well-known causative factor of catheter- and medical device-related sepsis. Its high prevalence in coagulase-negative staphylococci (CoNS) has recently been reported. Information on biofilm production in CoNS isolated from wild animals is lacking. Herein, we studied the biofilm formation capabilities of CoNS isolated from rescued wild animals in the Republic of Korea. Swab samples were collected from the conjunctiva, nasal cavity, perianal area, and rectum for mammals while the sampling was done from the conjunctiva, oral mucosa, pericloacal area, and cloaca for birds. Isolation of CoNS was based on morphological and biochemical analyses along with molecular typing. Biofilm production was analyzed using 96-well plate based quantitative adherence assays. The studies demonstrated that CoNS of mammalian origin have higher biofilm-producing ability (70.4%) than the isolates from birds (62.5%). In particular, all methicillin-resistant (MR) CoNS isolated from mammals were capable of biofilm formation while only 63.3% of MR CoNS isolated from birds could produce biofilms. The MR CoNS isolated from mammals also had a significantly higher ability to form biofilms (100%) than methicillin susceptible CoNS (60.0%) than those isolates from birds. The findings show that wild animals may act as reservoirs as well as possible transmitters of biofilm-mediated antibiotic resistant genes.

“…The ability of S. pseudintermedius to produce biofilms has been previously reported. In Japan, all S. pseudintermedius isolates were able to produce biofilm [ 17 ], while in South Korea, a biofilm-forming quantitative assay showed that all S. pseudintermedius isolates produced either strong or moderate biofilm [ 18 ].…”

Antibiotic Resistance Profile and Biofilm Production of Staphylococcus pseudintermedius Isolated from Dogs in Thailand

et al. 2021

Staphylococcus pseudintermedius is a zoonotic pathogen that can cause life-threatening infections in animals and humans. The study of methicillin-resistant S. pseudintermedius (MRSP) and its ability to produce biofilms is important to select the most suitable treatment. The prevalence and characteristics of S. pseudintermedius isolated from dogs admitted at the Veterinary Teaching Hospital, Prince of Songkla University, Thailand were assessed. Results showed that 28.30% (15/53) of the isolates were MRSP. Amplification of the mecA gene was observed in 93.33% (14/15) MRSP. Methicillin-resistant strains revealed co-resistant patterns against other antibiotics, including chloramphenicol, clindamycin, tetracycline, clarithromycin, ciprofloxacin, and trimethoprim. In this study, all bacterial isolates produced biofilms, while 90.55% of S. pseudintermedius isolates were strong or moderate biofilm producers. Most (45–60%) of the resistant strains were strong biofilm producers, while the correlation between biofilm production and antibiotic resistance was not statistically significant. This is the first study in southern Thailand to investigate the drug-resistant profile of S. pseudintermedius and its ability to form biofilm. The results will contribute to a better understanding of the emergence and prevalence of antimicrobial resistance in S. pseudintermedius.

“…Some studies reported that MRSP‐ST71 can produce biofilms, suggesting the necessity of investigating the prevalence of biofilm‐producing S. pseudintermedius and their implications on AMR in veterinary medical practices (Dicicco et al, 2012 ; Osland et al, 2012 ; Singh et al, 2013 ). The icaA and icaD genes responsible for biofilm production were detected among healthy dogs' isolates in one study (Han et al, 2015 ).…”

The molecular ecology of Staphylococcus aureus, Staphylococcus pseudintermedius and their methicillin‐resistant strains in healthy dogs and cats could serve as good models to understand the concept of bacterial zoonosis due to animal companionship. This study aims to provide insights into pooled prevalence, genetic lineages, virulence and antimicrobial resistance (AMR) among healthy dogs and cats. Original research and brief communication articles published from 2001 to 2021 that reported the nasal detection of S. aureus and S. pseudintermedius in healthy dogs and cats in the community, homes and outside veterinary clinics were examined and analysed. Forty‐nine studies were eligible and included in this systematic review. The pooled prevalence of nasal carriage of S. aureus/methicillin‐resistant S. aureus (MRSA) in healthy dogs and cats were 10.9% (95% CI: 10.1–11.9)/2.8% (95% CI: 2.4–3.2) and 3.2% (95% CI: 1.9–4.8)/0.5% (95% CI: 0.0–1.1), respectively. Conversely, the pooled prevalence of S. pseudintermedius/methicillin‐resistant S. pseudintermedius (MRSP) in healthy dogs and cats were 18.3% (95% CI: 17.1–19.7)/3.1% (95% CI: 2.5–3.7) and 1.3% (95% CI: 0.6–2.4)/1.2% (95% CI: 0.6–2.3), respectively. Although highly diverse genetic lineages of S. aureus were detected in healthy dogs and cats, MSSA‐CC1/CC5/CC22/CC45/CC121/CC398 and MRSA‐CC5/CC93/CC22/CC30 were mostly reported in dogs; and MSSA‐CC5/CC8/CC15/CC48 and MRSA‐CC22/CC30/CC80 in cats. Of note, MSSA‐CC398 isolates (spa‐types t034 and t5883) were detected in dogs. Genetic lineages often associated with MSSP/MRSP were ST20/ST71, highlighting the frequent detection of the epidemic European MRSP‐ST71 clone in dogs. S. aureus isolates carrying the luk‐S/F‐PV, tst, eta, etb and etd genes were seldomly detected in dogs, and luk‐S/F‐PV was the unique virulence factor reported in isolates of cats. S. pseudintermedius isolates harbouring the luk‐S/F‐I, seint and expA genes were frequently found, especially in dogs. High and diverse rates of AMR were noted, especially among MRSA/MRSP isolates. There is a need for additional studies on the molecular characterization of isolates from countries with under‐studied nasal staphylococci isolates.
