Case Report: The First Report on Moraxella canis Isolation From Corneal Ulcer in a Bulldog.

ABSTRACT: A 5-year-old castrated male bulldog was diagnosed with a corneal ulcer accompanied by edema and conjunctival hyperemia. Ophthalmic examination and microbiological analysis were performed, and the bacteria were found to be gram-negative and globular. The isolated clone was identified as Moraxella canis (MZ579539) via MALDI-TOF MS and 16S rDNA sequencing. Antimicrobial susceptibility testing showed that the bacteria were sensitive to tetracycline and chloramphenicol, but resistant to levofloxacin and ciprofloxacin. After a conjunctival flap was placed, tobramycin ophthalmic solution and 5% sodium hyaluronate were administered. Following surgery, the ulcer was effectively controlled, and after 3 weeks, the cornea healed. This is the first case report of a canine corneal ulcer associated with M. canis, which should be considered when corneal ulceration or keratitis were suspected.

Bacteremia due to Moraxella osloensis: a case report and literature review.

Project description:Herein we report the case of a 10-year-old boy with an autosomal mosaic mutation who developed bacteremia. The causative agent was identified as Moraxella osloensis by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry and 16S rRNA gene sequencing. In the pediatric population, there have been 13 case reports of infection attributed to M. osloensis and this is the fifth reported case of pediatric bacteremia due to M. osloensis. After Moraxella species infection was confirmed, the patient recovered with appropriate antimicrobial therapy. It is important to consider that M. osloensis can cause serious infections, such as bacteremia, in otherwise healthy children.

The first report of terbinafine resistance Microsporum canis from a cat.

Project description:A 2-year-old, exotic shorthair cat presented with baldness and mild scaling on trunk that was confirmed as Microsporum canis (M. canis) infection by the following methods. Wood's lamp and trichogram were used to demonstrate fungal elements suggestive of dermatophytosis consistent with M. canis. Dermatophyte test medium (DTM) and polymerase chain reaction (PCR) were used for identification. E-test and broth microdilution test were then utilized to estimate antifungal minimal inhibitory concentrations (MICs) towards ITZ and TRF respectively. The strain was isolated from the patient and revealed TRF MIC >32 µg/ml and ITZ MIC 0.023 µg/ml. Patient was cured of dermatophytosis with systemic ITZ.

First report of a new corneal pathogen: Phaeoacremonium parasiticum.

Project description:Keratitis is a public health issue in developing countries and a potentially sight-threatening condition. Collagen fibrils in the corneal stroma are parallels to each other. Fundamental substance maintains the same space between collagen fibrils. That is how corneal transparency can be achieved. Any damage which can modify this structure will lead to corneal opacity and loss of vision. Fungal keratitis might appear in up to one-third of cases. Nevertheless, fungal keratitis remains poorly described and understood. Herein, we present the first ever reported case of corneal infection due to Phaeoacremonium parasiticum in a young patient. We describe the clinical and microbial characteristics, and we also discuss the use of confocal microscopy in early diagnosis of this infection.

Case report: First isolation of Exophiala dermatitidis from subcutaneous phaeohyphomycosis in a cat.

Project description:Phaeohyphomycosis, which is caused by the opportunistic black yeast-like fungus Exophiala dermatitidis, has been reported in humans and dogs. However, no previous studies describing E. dermatitidis infections in cats have been published. Herein, we report a case of subcutaneous phaeohyphomycosis caused by E. dermatitidis. A 12-year-old, castrated male Japanese domestic short-haired cat presented with a solitary subcutaneous abscess on the left side of the neck, where an esophageal tube for force-feeding had been placed previously. The cat was diagnosed with hepatitis and was treated with prednisolone. The subcutaneous abscess was incised using a scalpel blade and the pus was excreted. The cytology of the pus revealed hyphae with neutrophil and macrophage infiltration. Although the cat was treated with oral itraconazole or an infusion of topical ketoconazole cream applied to the lesion, it died. The fungal culture of the pus specimen developed dark-green, waxy, smooth, yeast-like colonies. Sequencing of the internal transcribed spacer 1-4 regions of the ribosomal DNA of the pus specimen showed 100% identity with that of the standard strains of E. dermatitidis. Based on these results, the cat was diagnosed with subcutaneous phaeohyphomycosis caused by E. dermatitidis. The antifungal susceptibility test revealed that the fungus showed low or moderate susceptibility to the antifungal drugs examined, except for amphotericin B, which exhibited high in vitro antifungal activity. This is the first case report to provide definitive evidence of E. dermatitidis infection in cats and antifungal susceptibility test results against clinically isolated E. dermatitidis.

First reported isolation of Neisseria canis from a deep facial wound infection in a dog.

Project description:Neisseria canis was isolated in pure culture from a mandibular abscess in a dog. Ultrasound-guided fine-needle aspiration was used to obtain a sample from the abscess. Conventional bacteriological examination techniques followed by 16S rRNA gene sequencing from pure subculture and construction of a phylogenetic tree verified the isolate as N. canis. 16S rRNA sequence analysis revealed that a broader phylogenetic platform is needed in the part of the phylogenetic tree where the canine pathogenic N. canis isolate is located. The canine pathogenic isolate was found to be resistant to cephalexin and trimethoprim.

First report of Cryptosporidium canis in farmed Arctic foxes (Vulpes lagopus) in China.

Project description:BackgroundCryptosporidium is an important genus of enteric zoonotic parasites, which can infect a wide range of animals including foxes. Little information is available concerning the prevalence and molecular characterisation of Cryptosporidium spp. in farmed Arctic foxes (Vulpes lagopus) in China. Thus, the objective of the present study was to investigate the prevalence of Cryptosporidium spp. in Arctic foxes in China using nested PCR amplification of the small subunit ribosomal RNA (SSU rRNA) gene.FindingsThe overall prevalence of Cryptosporidium spp. in Arctic foxes was 15.9 % (48/302), with 12.9 % in male (18/139) and 18.4 % in female (30/163) foxes, respectively. The prevalence in different farms varied from 0 to 31.43 %. The prevalence of infection in different age groups varied from 14.1 % to 19.0 %. Foxes from Hebei Province (7.8 %, 11/141) had a significantly lower Cryptosporidium spp. prevalence than those from Heilongjiang Province (22.9 %, 16/70) and Jilin Province (23.1 %, 21/91) (P= 0.0015). Sequence analysis of the SSU rRNA gene indicated that all the 48 isolates represented C. canis.ConclusionsThis is the first report of C. canis infection in farmed Arctic foxes in China, which also provides foundation data for preventing and controlling Cryptosporidium infection in foxes, other animals and humans.

Isolation and characterization of Leptospira licerasiae in Austrian swine - a first-time case report in Europe.

Project description:BackgroundLeptospiraceae comprise a diverse family of spirochetal bacteria, of which many are involved in infectious diseases of animals and humans. Local leptospiral diversity in domestic animals is often poorly understood. Here we describe the incidental detection of Leptospira (L.) licerasiae in an Austrian pig.Case presentationDuring an experiment to characterize the pathogenesis of L. interrogans serovar Icterohaemorrhagiae in pigs, cultivation of a urine sample from a non-challenged contact pig resulted in growth of a spirochetal bacterium that tested negative for pathogenic Leptospira (LipL32 gene). PCR, Sanger sequencing and standard serotyping further confirmed that the recovered isolate was clearly different from the challenge strain L. interrogans serovar Icterohaemorrhagiae used in the animal experiment. Whole genome sequencing revealed that the isolate belongs to the species L. licerasiae, a tropical member of the Leptospiraceae, with no prior record of detection in Europe.ConclusionsThis is the first report describing the occurrence of L. licerasiae in Europe. Since L. licerasiae is considered to have intermediate pathogenicity, it will be important to follow the geographical distribution of this species and its pathogenic and zoonotic potential in more detail.

Multiple chromoanasynthesis in a rare case of sporadic renal leiomyosarcoma: case report

Project description:Renal leiomyosarcomas (LMS) are extremely rare neoplasms with aggressive behaviour and poor survival prognosis. The most frequent somatic events in leiomyosarcomas are mutations in TP53, RB1, ATRX and PTEN genes, chromosomal instability and chromoanagenesis. By using chromosomal microarray analysis we identified monosomy of chromosomes 3 and 11, gain of Xp (ATRX) arm and three chromoanasynthesis regions (6q21-q27, 7p22.3-p12.1 and 12q13.11-q21.2), with MDM2 and CDK4 oncogenes copy number gains, whereas no CNVs or tumor specific SNVs in TP53, RB1 and PTEN genes were observed.
