is a Gram-negative facultative anaerobic bacterium that is a typical commensal of the oral cavity and enteric tract of domestic animals. Human infections caused by this species are most often associated with dog bites and rarely with other animal bites. In this report, we present a case of a 34-year-old man who developed soft tissue infection of the left hand after a cat bite. The patient was successfully treated by a surgical intervention and antibiotics. The species identification of the isolate was performed by a conventional automatic system and nucleic acid-based methods. The nucleic acid-based methods provide a powerful alternative to the conventional microbiological diagnostic of these bacteria.

In this review, we would like to demonstrate the case of a 6-year-old girl who presented with progressive ankle pain and eventual inability to weight bear. She was shown to have primary acute osteomyelitis of the talus caused by , a commensal organism usually found in the oropharynx of dogs, despite the absence of any history of a dog bite or other zoonotic risk factors. We characterise the symptoms, signs, radiographic appearances and result of both the medical and surgical management, including a review of the literature. This review aims to increase awareness of this rare pathology and help guide other clinicians in accurately diagnosing and managing the condition.

The complications of wound infections caused by animal related trauma are well known and explored. Of the numerous polymicrobial etiologies, Neisseria animaloris and Pasteurella canis oralis have been reported only in a limited number of cases. This manuscript explores the rare finding of these species in the case of an 83-year-old male with a diabetic foot wound complicated by infection from the saliva of his pet dog. The case highlights the first instance of P. canis oralis without the setting of a penetrating animal bite, emphasizing the vulnerability of open lesions in patients whose comorbidities impair proper wound healing. These bacteria are susceptible to beta-lactams with beta-lactamase inhibitors and can be treated once identified. It is crucial to recognize rare pathogens and initiate appropriate treatment early, and to emphasize proper wound care, especially in the context of pet interactions.

Biotypic and genotypic diversity in Pasteurella canis isolated from host animals and humans: differences in trehalose fermentation and nucleotide sequences encoding trehalose-6-phosphate hydrolase (treC).
The biotypic and genotypic features of Pasteurella canis isolated from dogs, cats, and humans were clarified by repetitive sequence-based fingerprinting and nucleotide sequences encoding trehalose-6-phosphate hydrolase (treC). Thirty P. canis and 48 P. multocida isolates were collected from dogs, cats, and humans to perform biotyping. The genotyping of P. canis by fingerprinting was followed by dendrogram construction. The whole-genome sequences (WGSs) were searched for the enzyme-coding nucleotide sequences around the main and adjacent loci constituting the operon. Full-length nucleotide sequences encoding the enzyme were determined using polymerase chain reaction and direct sequencing. Biotypic results were compared to the dendrogram and nucleotide sequence data. We observed a difference in trehalose fermentation with a positivity rate of 46.7%. Two (A-1/A-2) and three (B-1/B-2/B-3) clades were located on the dendrograms generated based on two repetitive sequence-based fingerprinting techniques, showing no association between trehalose fermentation and the clades. Based on the WGSs, two variants of the gene, namely, a 1,641 bp gene treC and a pseudogene (1,335 bp) of treC with its first 306 nucleotides deleted, were observed. Trehalose-positive isolates harbored treC, whereas trehalose-negative isolates lacked treC with or without the pseudogene. Our observations suggest biotypic and genotypic diversity among the P. canis isolates from animal and human hosts, with respect to trehalose fermentation and treC nucleotide sequences. This is the first report on the diversity of treC nucleotide sequences among these isolates.

A range of analytical methods (GC-MS, LC-MS, voltammetry, microbiological and microscopic techniques, PCR) was used to assay a range of potential chemical and biological contaminants in soil and dandelion samples. The results provide the first comprehensive safety analysis of dandelion as a herbal product. Samples were collected from three different sites in Poland where the local population collects dandelion plants for their own consumption: Rudenka (a mountain meadow in the European Ecological Network of Natura 2000 protection area, free of agrotechnical treatments for over 30 years), Warszawa 1 (dense single-family housing with heavy traffic), and Warszawa 2 (recreation area with heavy traffic near a coal-fired heat and power plant). The assays of heavy metals and other chemical pollutants (PAHs, PCBs, dioxins, pesticides, mycotoxins) confirm that all collected soil and dandelion samples were chemically pure; however, 95 species of pathogenic bacteria were detected, including "carnivorous" Vibrio vulnificus, zoonotic Pasteurella pneumotropica, Pasteurella canis, Staphylococcus pseudintermedius, Staphylococcus lentus and Francisella tularensis as well as 14 species of pathogenic fungi and one protozoan parasite (Giardia intestinalis). The discovery of septicemia agents V. vulnificus, Fusobacterium mortiferum and Rahnella aquatilis in the soil surrounding dandelion roots and in the flowers, G. intestinalis in dandelion leaves and roots samples, all collected in Warsaw, is highly disturbing. This finding underlines the need for increased caution when collecting dandelion in densely populated areas with a large population of pets. Thorough washing of the harvested plants is necessary before using them for consumption, especially in the case of making salads from fresh dandelion leaves, which is becoming increasingly popular among people leading healthy and an environmentally friendly lifestyle.

INTRODUCTION
HO with concurrent chronic osteomyelitis is extremely rare. To the authors' knowledge, this is the first case in the English-language literature with wound infection and mature HO with chronic osteomyelitis caused by mixed infection of Pasteurella canis, Peptoniphilus coxii, Peptostreptococcus canis, and Fusobacterium nucleatum following licking of a wound by a domesticated dog.
CASE REPORT
A 49-year-old female with a painful, swollen, and purulent wound with bone exposure, measuring 2.5 cm × 1.5 cm, on the right leg was referred after an unsuccessful 3-month treatment regimen for an open wound resulting from a motorcycle accident. The patient's dog licked the wound several times 1 week after the accident. Sequestrectomy and debridement were performed after a 3-week OPD treatment. Postoperative treatment included NPWT applied for 6 days, 1 week of open wound care, STSG 2 weeks after the first operation, and IV antibiotics for 3 weeks. Pathologic examination was positive for HO with chronic osteomyelitis. The patient was discharged 3 weeks after admission under stable condition followed by OPD treatment. Wound healing was achieved 2 months after discharge.
CONCLUSIONS
Repeated licking of the patient's wound by her dog caused the colonization of pathogens from the dog's saliva, and inappropriate wound care by the patient herself resulted in HO with chronic osteomyelitis, which was successfully treated with a regimen of NPWT, open wound care, STSG, and IV antibiotics.

BACKGROUND
Comparative analysis of virulence factors (VFs) between and are lacking, although both cause zoonotic infections. We determined the virulence-associated genome sequence characteristics of and assessed the toxin gene prevalence unique to among clinical isolates of and .
METHODS
We selected 10 and 16 whole-genome sequences (WGSs) from the National Center for Biotechnology database. The VFanalyzer tool was used to estimate -characteristic VFs. Amino acid sequences of VFs were compared with multiple-aligned sequences. The genome structure containing -characteristic and adjacent loci was compared to the corresponding genome structure. After designing primer sequences and assessing their accuracy, we examined the gene prevalence of the -characteristic VFs using PCR among clinical isolates of and .
RESULTS
Using VFanalyzer, we found virulence-associated cytolethal distending toxin () loci common to all WGSs that were not found in WGSs. Similarities in the multiple alignments of CdtA-CdtB-CdtC amino acid sequences were found among the 10 WGSs. Shared or similar loci around were identified between the and genome structures. The PCR-based prevalence differed for and clinical isolates.
CONCLUSIONS
-specific prevalence was identified among clinical isolates. These three loci may be unique toxin genes and promising targets for the rapid identification of in clinical settings.

BACKGROUND
As the clinical outcome of bite-associated infection is related to the oral commensals, evaluating their composition and antibiotic susceptibility pattern can provide more information for the antibiotic treatment of wound infections and increase the awareness of the multidrug-resistant bacteria in cat oral flora.
AIMS
This study was conducted to identify the various bacterial species in the oral cavity of cats. It aimed to identify the composition of cat oral flora and antibiotic resistant bacterial stains.
MATERIALS AND METHODS
Twenty-two cats were sampled for bacterial evaluation. Matrix-assisted laser desorption/ionization time of flight mass spectrometry was used to provide rapid and reliable detection and identification of the bacterial species. Antibiotic susceptibility tests were performed in the identified isolates to determine the antibiotic susceptibility pattern and to detect the multidrug-resistant bacteria in the cat oral cavities.
RESULTS
A total of 54 isolates were identified, Pasteurella was the genus most commonly isolated from the oral cavity of cats (19/54, 35.19%), followed by Neisseria spp. (8/54, 14.81%) and Staphylococcus spp. (7/54, 12.96%). Uncommon oral flora were isolated from the samples, including Pasteurella canis, Inquilinus limosus and the Enterobacteriaceae family of Escherichia coli, Klebsiella pneumoniae and Serratia marcescens. Fourteen different multidrug-resistant bacteria were detected, including Pasteurella species (4/14), Bacillus species (2/14), Neisseria species (3/14), Escherichia species (1/14) and Staphylococcus species (4/14).
DISCUSSION AND CONCLUSIONS
This study's findings will increase the understanding of the composition of cat oral flora in Hong Kong, which can provide more evidence-based information for the prophylactic treatment of patients with cat bite infections. Moreover, the study identified and detected the antibiotic resistance pattern and multidrug-resistant bacteria in the cat oral cavity, which can help cat owners increase their awareness of maintaining regular oral hygiene for their cats to prevent the spread of pathogens from cats to humans.
