Methicillin-resistant Staphylococcus aureus (MRSA) carrying mecC gene (mecC-MRSA) is frequently reported among European hedgehogs (Europeaus erineaus) due to co-evolutionary adaptation to dermatophyte infection in European hedgehogs. The occurrence of MRSA in European hedgehogs in Finland is unknown. Consequently, we investigated the occurrence of MRSA in wild hedgehogs from urban Helsinki metropolitan area in 2020–2021 and applied whole genome sequencing (WGS) to further characterize the studied isolates and compared them with human clinical MRSA isolates. Altogether 115 dead hedgehogs were screened for MRSA using selective cultivation methods. Presumptive MRSA isolates were tested for antimicrobial susceptibility and confirmed MRSA isolates were further characterized by spa-typing and WGS. Hedgehog derived MRSA isolates were compared with clinical human MRSA isolates using core genome multilocus sequence typing (cgMLST). In total MRSA was recovered from 11 out of 115 (10%) hedgehogs. Among these four different spa types (t304; n = 4, t8835; n = 4, t5133; n = 2 and t622; n = 1) and three different sequence types (STs) (ST6; n = 6, ST7663; n = 4 and ST2840; n = 1) were identified. From the studied MRSA isolates seven harboured the mecA gene (mecA-MRSA) and four were identified as mecC-MRSA. All mecA-MRSA isolates carried immune evasion cluster genes, and one isolate was positive for Panton-Valentine leukocidin. cgMLST comparison revealed close genetic relatedness among three hedgehog and two human mecA-MRSA isolates all belonging to t304/ST6. Our results suggest a clonal dissemination of a successful MRSA clone among humans and hedgehogs. Further studies are warranted to investigate the sources and dissemination of such clone in urban environments. We observed a relatively low occurrence of mecC-MRSA in Finnish hedgehogs.

Vaccination constitutes one of the most important means of preventing infectious disease in captive nonhuman primates (NHPs). Vaccination protocols for NHPs vary, as they are mostly guided by institutional preference, infection pressure, local availability, and recommendations by non-peer reviewed resources. Currently, no updated literature review about vaccination options for NHP is available. Therefore, we provide a detailed overview of published vaccination options for NHP. Our findings demonstrate that, while there are often insufficient scientific data to justify their use, the core vaccines used in most NHP species confer protection against tetanus, rabies, and measles. Where information is available, efficacy expectations, adverse effects, dosages and frequency of administration are provided. We advocate that the decision to vaccinate NHP for less common diseases, for which an off-label vaccine is available, should be grounded in a comprehensive risk assessment. This assessment should consider factors specific to the individual animal, the vaccine, the housing institution, the epidemiology of the disease, and relevant regulatory and ethical considerations.

Background: Both invasive and non-invasive blood pressure measuring methods are used in clinical and experimental work in veterinary medicine and several studies validating these methods are published. The aim of this study was to assess the level of agreement between non-invasive and invasive arterial blood pressure measurements within a wide range of blood pressures in sheep. Six adult Texel-cross female sheep were included. Anaesthesia was induced with IV propofol (4–8 mg/kg) and maintained with sevoflurane in 50% oxygen and air. Blood pressure measurements were simultaneously obtained using both invasive methods (electronic pressure transducer (EPT) connected to the auricular and carotid arteries, and aneroid manometer connected to the auricular artery) and non-invasive methods (the oscillometric device (OD) and Doppler). Carotid artery EPT was considered the ‘gold standard’ to which other methods were compared. The agreement between the two methods was evaluated with the Bland-Altman method, in conditions of normotension, hypertension (MAP > 160 mmHg, induced with phenylephrine), and hypotension (MAP < 50 mmHg, induced with acepromazine). The devices were evaluated using the American College of Veterinary Internal Medicine guidelines. Results: Carotid MAP values ranged from 37 to 192 mmHg. Mean bias and limits of agreement were − 2.8 mmHg and − 11–5.4 mmHg for the auricular EPT MAP; 5.1 mmHg and − 12.2–22.3 mmHg for the aneroid manometer MAP; − 2.7 mmHg and − 23.9–18.6 mmHg for the OD MAP; − 1.5 mmHg and − 20.1–23.2 mmHg for the Doppler SAP; respectively. Correlation coefficients for all methods were > 0.95. Conclusions: Doppler SAP and OD MAP demonstrated acceptable accuracy over a broad blood pressure range, supporting their utility for sheep as surrogate of invasive methods of measuring blood pressure. Auricular EPT was the best surrogate of central arterial pressure to be used in clinical conditions.
