ABSTRACT Despite tight biosecurity measures, an outbreak of respiratory disease rapidly spread across the Icelandic equine population in 2010. Horse transportation was brought to a halt in order to contain the spread of the infectious agent. In a recent article, Björnsdóttir and colleagues (S. Björnsdóttir et al., mBio 8:e00826-17, 2017, https://doi.org/10.1128/mBio.00826-17 !) employ the power and resolution of “genomic epidemiology,” the combination of whole genomic sequencing and epidemiological approaches, to examine the source and spread of the outbreak. Intriguingly, the outbreak was not viral in origin, but linked to a bacterial “commensal” Streptococcus equi subsp. zooepidemicus infection. A national sampling strategy coupled with population genomics revealed that the outbreak was most likely driven by a S. equi subsp. zooepidemicus sequence type 209 (ST209) infection that spread nationally from a single source. This retrospective study demonstrates the power of genomics applied on a national scale to unravel the cause of a significant biosecurity threat.

Streptococcus equi subspecies zooepidemicus (S. zooepidemicus) is mostly known as an opportunistic pathogen found in horses and as a rare human zoonosis. An 82-year-old male, who had daily contact with horses, was admitted in a septic condition. The patient presented with dyspnea, hemoptysis, impaired general condition, and severe pain in a swollen left shoulder. Synovial fluid from the affected joint and blood cultures showed growth of S. equi subsp. zooepidemicus. Transesophageal echocardiography showed a vegetation on the aortic valve consistent with endocarditis. Arthroscopic revision revealed synovitis and erosion of the rotator cuff. Technetium-99m scintigraphy showed intense increased activity in the left shoulder, suspicious of osteitis. The infection was treated with intravenous antibiotics over a period of five weeks, followed by oral antibiotics for another two months. The patient recovered without permanent sequelae.

AbstractSalmonella, as a zoonotic pathogen, has attracted widespread attention worldwide, especially in the transmission between household pets and humans. Therefore, we investigated the epidemic distribution of dog Salmonella from pet hospitals and breeding base in Xuzhou, Jiangsu Province, China, and used multilocus sequence typing (MLST) and clustered regularly interspaced short palindromic repeats (CRISPRs) to subtype Salmonella isolates. From April 2018 to November 2019, a total of 469 samples were collected from pet hospitals and breeding base, including 339 dog samples and 60 cat samples. S. Kentucky (40.74%) was the most prevalent serotype, but other, such as S. Typhimurium (18.52%) and S. Indiana (18.52%), were also widespread. Eight different sequence type (ST) patterns were identified by MLST and ST198 was the highest proportion of these isolates. CRISPRs analysis showed that 9 different Kentucky CRISPR types (KCTs) was identified from ST198. 48 spacers including 29 (6 News) for CRISPR1 and 19 (4 News) for CRISPR2 that proved the polymorphic of Salmonella genes in samples from different sources. The analysis demonstrated that the common serotypes were widely present in pet hosts in the same area. This analysis shows that CRISPR genes have better recognition ability in the same serotype, which has a positive effect on the traceability of Salmonella and the prevention and treatment of salmonellosis.

Abstract Hydatid cyst is a zoonotic infection and a significant public health problem in low- and middle-income countries. A 79-year-old female patient was presented to the gynecology outpatient department with complaints of pain in the abdomen and difficulty in micturition, with a mass palpable per speculum. The ultrasound was suggestive of an ovarian cystadenocarcinoma, whereas computed tomography of the abdomen favored hydatid cyst with adnexal neoplasm as a differential diagnosis. Considering the contradictory findings, a frozen section was sent to confirm the diagnosis, which showed hooklets of Echinococcus granulosus/hydatid cyst under the microscope. This was a rare case of pelvic hydatid cyst mimicking ovarian malignancy and was associated with a less-preferred mode of investigation (frozen section). This article focuses on how a frozen section, despite its limitations and being expensive, can still be considered for accurate patient management.
