RESUMEN

Campylobacter pinnipediorum was described recently for isolates recovered from pinnipeds. The novel species was further split into 2 subspecies based on host and geography, with C. pinnipediorum subsp. pinnipediorum recovered from otariid seals in California (USA) and C. pinnipediorum subsp. caledonicus recovered from phocid seals in Scotland. We report details of the infections of 7 pinnipeds from which C. pinnipediorum was isolated: C. pinnipediorum subsp. caledonicus was isolated from 2 harbour seals Phoca vitulina and a single grey seal Halichoerus grypus, and C. pinnipediorum subsp. pinnipediorum was isolated from California sea lions Zalophus californianus. Six of the isolates were recovered from samples collected at post-mortem investigation. In 2 of the Scottish seals and in 3 of the California seals, C. pinnipediorum was the sole bacterial isolate recovered from abscesses present and suggests they may have resulted from conspecific or intraspecific bite wounds.

RESUMEN

Using metagenomic analysis, we identified a novel picornavirus in young preweaned lambs with neurologic signs associated with severe nonsuppurative encephalitis and sensory ganglionitis in 2016 and 2017 in the United Kingdom. In situ hybridization demonstrated intralesional neuronotropism of this virus, which was also detected in archived samples of similarly affected lambs (1998-2014).

RESUMEN

This study describes the occurrence of suspected wildlife crimes submitted for forensic examination in Scotland in 2010. The study aims were to determine which types of crimes were committed, which species were targeted, and the outcome of investigations, in order to assess the contribution of forensic examinations in the prosecution of wildlife crimes. Information on suspected wildlife crimes submitted between January 1 and December 31, 2010 to the SAC Consulting: Veterinary Services Disease Surveillance Centers, Science and Advice for Scottish Agriculture, and to the University of Glasgow, was used. The location of suspected crimes, the species targeted, cause of death, and types of the 188 submitted wildlife crimes were summarized. More information regarding cases involving birds were submitted than cases involving mammals, and included 114 raptors, 14 waterfowl, and 22 "other bird species." Mammal cases (n = 38) included 12 badgers, 8 foxes, 7 deer, 4 hares, and 7 "other mammals." The cause of death was determined in 124 suspected crimes; malicious or accidental trauma was the most likely cause of death in 72, and 33 were poisoned. Forensic evidence supporting criminal activity was found in 53 cases, and poisoning was the most frequent crime recorded. At least five individuals were successfully prosecuted, representing 2.7 % of submissions. It was challenging to track cases from submission through to prosecution and laboratories conducting forensic investigations were often not informed of the outcome of prosecutions or court decisions.

RESUMEN

The UK and Europe have seen successive outbreaks of highly pathogenic avian influenza across the 2020/21 and 2021/22 autumn/winter seasons. Understanding both the epidemiology and transmission of these viruses in different species is critical to aid mitigating measures where outbreaks cause extensive mortalities in both land- and waterfowl. Infection of different species can result in mild or asymptomatic outcomes, or acute infections that result in high morbidity and mortality levels. Definition of disease outcome in different species is of great importance to understanding the role different species play in the maintenance and transmission of these pathogens. Further, the infection of species that have conservation value is also important to recognise and characterise to understand the impact on what might be limited wild populations. Highly pathogenic avian influenza virus H5N1 clade 2.3.4.4b has been detected in great skuas (Stercorarius skua) across different colonies on islands off the shore of Scotland, Great Britain during summer 2021. A large number of great skuas were observed as developing severe clinical disease and dying during the epizootic and mortalities were estimated to be high where monitored. Of eight skuas submitted for post-mortem examination, seven were confirmed as being infected with this virus using a range of diagnostic assays. Here we overview the outbreak event that occurred in this species, listed as species of conservation concern in Great Britain and outline the importance of this finding with respect to virus transmission and maintenance.

RESUMEN

OBJECTIVES: The aim of the study was to find evidence of SARS-CoV-2 infection in UK cats. DESIGN: Tissue samples were tested for SARS-CoV-2 antigen using immunofluorescence and for viral RNA by in situ hybridisation. A set of 387 oropharyngeal swabs that had been submitted for routine respiratory pathogen testing was tested for SARS-CoV-2 RNA using reverse transcriptase quantitative PCR. RESULTS: Lung tissue collected post-mortem from cat 1 tested positive for both SARS-CoV-2 nucleocapsid antigen and RNA. SARS-CoV-2 RNA was detected in an oropharyngeal swab collected from cat 2 that presented with rhinitis and conjunctivitis. High throughput sequencing of the viral genome revealed five single nucleotide polymorphisms (SNPs) compared to the nearest UK human SARS-CoV-2 sequence, and this human virus contained eight SNPs compared to the original Wuhan-Hu-1 reference sequence. An analysis of the viral genome of cat 2 together with nine other feline-derived SARS-CoV-2 sequences from around the world revealed no shared cat-specific mutations. CONCLUSIONS: These findings indicate that human-to-cat transmission of SARS-CoV-2 occurred during the COVID-19 pandemic in the UK, with the infected cats developing mild or severe respiratory disease. Given the ability of the new coronavirus to infect different species, it will be important to monitor for human-to-cat, cat-to-cat and cat-to-human transmission.

RESUMEN

Neisseria animaloris is considered to be a commensal of the canine and feline oral cavities. It is able to cause systemic infections in animals as well as humans, usually after a biting trauma has occurred. We recovered N. animaloris from chronically inflamed bite wounds on pectoral fins and tailstocks, from lungs and other internal organs of eight harbour porpoises. Gross and histopathological evidence suggest that fatal disseminated N. animaloris infections had occurred due to traumatic injury from grey seals. We therefore conclude that these porpoises survived a grey seal predatory attack, with the bite lesions representing the subsequent portal of entry for bacteria to infect the animals causing abscesses in multiple tissues, and eventually death. We demonstrate that forensic microbiology provides a useful tool for linking a perpetrator to its victim. Moreover, N. animaloris should be added to the list of potential zoonotic bacteria following interactions with seals, as the finding of systemic transfer to the lungs and other tissues of the harbour porpoises may suggest a potential to do likewise in humans.

RESUMEN

Bovine respiratory syncytial virus is an agent involved in calf pneumonia complex, a disease of significant economic importance. Accurate diagnosis of the agents involved on farm premises is important when formulating disease control measures, including vaccination. We have developed a real time reverse transcriptase polymerase chain reaction (rtRT-PCR) and compared it with the diagnostic tests currently available in the United Kingdom: immunohistochemistry (IHC) and immunofluorescence antibody test (IFAT). The rtRT-PCR had a detection limit of 10 gene copies and was 96% efficient. Recent UK isolates and clinical samples were tested; the rtRT-PCR was more sensitive than both conventional tests.

RESUMEN

BACKGROUND: Unlike non-seasonal depression, there is some evidence that seasonal affective disorder (SAD) is more common among more affluent socioeconomic groups. METHODS: In primary care settings in Aberdeen, 4557 subjects had previously completed a Seasonal Pattern Assessment Questionnaire (SPAQ). From the subjects' postcodes they were allocated a Carstairs score which placed them in one of seven categories of socioeconomic deprivation. These categories were compared with regard to seasonal pathology from the SPAQ ratings. RESULTS: Complete postcodes and Carstairs scores were established for 3772 (83%) of the 4557 subjects. No statistically significant relationship between socioeconomic deprivation and SPAQ ratings was detected. LIMITATIONS: The study population was an affluent one relative to Scotland as a whole which may have reduced the likelihood of a positive finding. The study was conducted 7 years after the census on which postcode deprivation scores were calculated, and changes therein may have occurred. CONCLUSIONS: SAD either has no relationship to social deprivation or is associated with affluence and this distinguishes it from non-seasonal depression.

RESUMEN

Bovine abortion represents a major animal welfare issue and a cause of substantial economic loss yet the rate of successful diagnosis remains low. Chlamydia-related organisms including Parachlamydia have recently emerged as putative cattle abortifacients. Placental tissue samples and fetal lung from bovine abortion submissions across Scotland in Spring 2011 were investigated by histopathology for the presence of suspect Chlamydia-related organisms. Evidence of Chlamydia-related organisms was observed in 21/113 (18.6%) placenta samples. Thirteen of the suspect cases and 18 histopathology negative cases were analysed by molecular and immunohistochemical methods. All samples were PCR positive for Parachlamydia but sequencing revealed high homology between identified environmental 16S sequences in all but three cases. Parachlamydial antigen was detected in 10/31 placental samples (32.2%) with pathology consistent with chlamydial infection. This work supports the need for further surveillance investigations and experimental studies to determine the role of Parachlamydia in bovine abortion.

RESUMEN

Bovine neonatal pancytopenia (BNP; previously known as idiopathic haemorrhagic diathesis and commonly known as bleeding calf syndrome) is a novel haemorrhagic disease of young calves which has emerged in a number of European countries during recent years. Data were retrospectively collected during June to November 2010 for 56 case calves diagnosed with BNP between 17 March and 7 June of the same year. These were compared with 58 control calves randomly recruited from herds with no history of BNP. Multivariable logistic regression analysis showed that increased odds of a calf being a BNP case were associated with its dam having received PregSure® BVD (Pfizer Animal Health) vaccination prior to the birth of the calf (odds ratio (OR) 40.78, p<0.001) and its herd of origin being located in Scotland (OR 9.71, p = 0.006). Decreased odds of a calf being a BNP case were associated with the calf having been kept outside (OR 0.11, p = 0.006). The longer that a cattle herd had been established on the farm was also associated with decreased odds of a calf in that herd being a BNP case (OR 0.97, p = 0.011).

RESUMEN

Mycoplasma species were recovered from 10 cetacean carcasses that stranded around Scotland. Mycoplasma phocicerebrale was isolated from the lungs of three harbor porpoises (Phocoena phocoena) as well as from the liver of one of these animals. Novel Mycoplasma spp. were isolated from the lungs of five additional harbor porpoises and the kidney of another. In addition an isolate closely related to Mycoplasma species 13CL was obtained from the kidney of a Sowerby's beaked whale (Mesoplodon bidens). The role of these Mycoplasma species in the disease of cetaceans, their host specificity, diversity, and any relation to cetacean strandings are unknown.

RESUMEN

BACKGROUND: Little is known about the presentation and management of seasonal affective disorder (SAD) in primary care. AIMS: To determine the use of health care services by people suffering from SAD. METHOD: Following a screening of patients consulting in primary care, 123 were identified as suffering from SAD. Each was age- and gender-matched with two primary care consulters with minimal seasonal morbidity, yielding 246 non-seasonal controls. From primary care records, health care usage over a 5-year period was established. RESULTS: Patients with SAD consulted in primary care significantly more often than controls and presented with a wider variety of symptoms. They received more prescriptions, underwent more investigations and had more referrals to secondary care. CONCLUSIONS: Patients with SAD are heavy users of health care services. This may reflect the condition itself, its comorbidity or factors related to the personality or help-seeking behaviour of sufferers.
