Abstract
The transparency of the cornea is critical to its role in transmitting light. Loss of corneal transparency results in visual impairment. Corneal pigmentation results from melanin accumulation in the epithelial cells of the cornea. Differential diagnosis for corneal pigmentation include corneal sequestrum, corneal foreign body, limbal melanocytoma, iris prolapse, and dermoid. These conditions must be excluded to reach a diagnosis of corneal pigmentation. A myriad of ocular surface conditions are associated with corneal pigmentation, including qualitative and quantitative tear film deficiency, adnexal disease, corneal ulceration, and breed-related corneal pigmentation syndromes. Accurate etiologic diagnosis is critical to determining effective treatment.

Cho H, Jeong M, Yoo S. A case of Candida albicans-induced fungal keratitis in a Chihuahua dog – with a focus on optical coherence tomographic features. J Vet Sci 2023; 24:e30. [PMID: 37012038 PMCID: PMC10071276 DOI: 10.4142/jvs.22131] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2022] [Revised: 02/12/2023] [Accepted: 02/17/2023] [Indexed: 03/17/2023] Open
Abstract
A 4-year-old Chihuahua dog was referred for bilateral corneal ulcers. Slightly raised white fluorescein-positive plaque-like corneal lesions in both eyes appeared as intense hyperreflective areas with posterior shadowing on optical coherence tomography (OCT). Based on corneal cytology and culture, Candida albicans-induced fungal keratitis was diagnosed. Despite treatment, on OCT, endothelial plaques, increased stromal infiltration thickness, vertical shapes of the ulcer edge, and necrotic stromal space were judged to be aggravation of the disease, and surgery was performed. Conjunctival grafting surgery with topical 1% voriconazole effectively resolved fungal keratitis. OCT can provide detailed and objective information related to the disease prognosis.

Abstract
OBJECTIVE The objective of the study was to compare corneal culture results using the ESwab™ and Amies charcoal swab. ANIMALS STUDIED One hundred fourteen canine and fifteen feline eyes. PROCEDURES Retrospective analysis of Dick White Referrals bacterial and fungal corneal culture data was conducted. Results were included from canine and feline patients, which presented with suspected infectious keratitis that had samples taken using an Amies charcoal swab followed by an ESwab™ in the same eye. In respect to positive and negative cultures, a McNemar test was conducted comparing instances of disagreement between swab types, and the Kappa coefficient (κ) was calculated to assess the level of agreement between swab types. RESULTS The ESwab™ produced more positive corneal cultures (71/129 [55.0%]) than the Amies charcoal swab (41/129 [31.8%]). 2/129 eyes produced positive fungal cultures. Considering 37/129 eyes in which both swab types detected a positive corneal culture, the same bacterial species were cultured from each swab type in 34/37 (91.9%) eyes, and an additional bacterial species was cultured by the ESwab™ in 3/37 (8.1%) eyes. In 34/38 (89.5%), instances of disagreement between swab types, the ESwab™ showed a positive culture, and the Amies charcoal swab showed a negative culture from the same eye, and this difference was significant (p < 0.0001). There was a moderate level of agreement between results from both swab types (κ = 0.432). CONCLUSIONS ESwab™ sampling alone may be superior to Amies charcoal swabs for detecting presence of bacteria in suspected infectious keratitis in cats and dogs.

Abstract
CASE DESCRIPTION Three dogs were presented for investigation of chronic nasal discharge and epistaxis 141, 250, and 357 days after undergoing transfrontal craniotomy to treat an intracranial meningioma (2 dogs) or a meningoencephalocele (1 dog). CLINICAL FINDINGS CT findings were consistent with destructive rhinitis and frontal sinusitis in all 3 dogs, with results of histologic examination and fungal culture of samples obtained during frontal sinusotomy confirming mycotic infection. Frontal sinusotomy revealed fungal plaques covering a combination of bone and residual surgical tissue adhesive at the site of the previous craniotomy in all 3 dogs. Aspergillus spp were identified in all 3 dogs, and Chrysosporium sp was also identified in 1 dog. TREATMENT AND OUTCOME Surgical curettage was followed by antifungal treatment (topical clotrimazole in 2 dogs and oral itraconazole for 3 months in 1 dog). Nasal discharge improved in the short-term but recurred in all dogs 99, 118, and 110 days after frontal sinusotomy. One dog received no further treatment, 1 dog received an additional 8.5 months of oral itraconazole treatment, and 1 dog underwent 2 additional surgical debridement procedures. At last follow-up, 2 dogs were alive 311 and 481 days after frontal sinusotomy; the third dog was euthanized because of status epilepticus 223 days after frontal sinusotomy. CLINICAL RELEVANCE Sinonasal mycosis should be considered as a potential complication in dogs developing persistent mucopurulent nasal discharge, intermittent epistaxis, and intermittent sneezing following transfrontal craniotomy. The pathophysiology may be multifactorial, and potential risk factors, including use of surgical tissue adhesive in the frontal sinus, require further investigation.

Survey on the Presence of Bacterial, Fungal and Helminthic Agents in Off-Leash Dog Parks Located in Urban Areas in Central-Italy. Animals (Basel) 2021; 11:ani11061685. [PMID: 34198875 PMCID: PMC8229923 DOI: 10.3390/ani11061685] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2021] [Revised: 05/25/2021] [Accepted: 06/03/2021] [Indexed: 12/24/2022] Open
Abstract
Simple Summary Off-leash dog parks are designated, generally fenced, public spaces where dogs can move freely under the supervision of their owners. These areas, allowing animals to socialize and run free, play a fundamental role in dogs’ welfare. However, such environments may be a source of different pathogens, even zoonotic, excreted by the attending animals. The present study evaluated the occurrence of bacterial, fungal, and parasitic pathogens in off-leash dog parks located in Florence (central Italy). Yersinia spp., Listeria innocua, Toxocara canis eggs and Ancylostoma caninum/Uncinaria stenocephala eggs were found in canine feces. Keratinophilic geophilic fungi (mostly Microsporum gypseum/A. incurvatum, Microsporum canis in a single case) were recovered from soil. Trichosporon sp. and Geotrichum candidum were isolated from two water samples. The obtained results suggest that, despite the not negligible canine fecal contamination of selected areas (feces were found in 88.5% of the parks), attending dogs did not act as important carriers for the investigated pathogens, although examined off-leash dog parks may represent a risk for the spreading of some dermatophytoses to both pets and their owners. Thus, in a One-Health perspective, periodical examinations to detect the main bacteriological, parasitological and mycological pathogens in different samples collected in off-leash dog parks are recommended. Abstract Off-leash dog parks are designated public spaces where dogs can move freely, under their owners’ supervision. These areas, allowing animals to socialize and move freely, are fundamental for dogs’ welfare. However, different pathogens, even zoonotic, may be excreted by the attending animals and contaminate the environment. The aim of the present study was to verify the occurrence of bacterial, fungal and parasitic pathogens in off-leash dog parks located in Florence (central Italy). Between March and May 2019, 83 fecal samples, 43 soil samples and 23 water samples (from fountains and puddles) collected from 26 off-leash fenced areas were examined. Fecal samples scored positive for Yersinia spp. (n = 7), Listeria innocua (n = 4), Toxocara canis eggs (n = 2) and Ancylostoma caninum/Uncinaria stenocephala eggs (n = 1). Keratinophilic geophilic fungi (mostly Microsporum gypseum /A. incurvatum) were recovered from 43 soil samples belonging to 23 out of 26 parks, along with Microsporum canis in a single case. Prototheca spp. was never isolated from water samples, while Trichosporon sp. was cultured in two cases, alone and in association with Geotrichum candidum. These results show that dogs did not act as important carriers for the investigated bacterial and parasitic pathogens, although examined areas may represent a risk for the spreading of some dermatophytoses to both pets and their owners. Periodical examinations to assess the main bacteriological, parasitological and mycological pathogens in different samples collected in off-leash dog parks should be carried out in a One-Health perspective.

Abstract
This case series describes six confirmed cases of mycotic encephalitis and/or mycotic pneumonia in southern pudu (Pudu puda). One case involved a 10.5-yr-old intact female that presented with an inability to stand, eventually progressing to grand mal seizures. Magnetic resonance imaging showed a lesion within the cerebellar vermis with edema causing cerebellar herniation. The animal was euthanized based on a grave prognosis. Gross and histologic examination revealed primary central nervous system phaeohyphomycosis. Curvularia spicifera was sequenced from the cerebellar tissue. This is the first time this fungus has been reported as a primary central nervous system infection in an artiodactyl species. The remaining five cases occurred in neonates between 17 and 67 days old. Clinical signs varied widely, including facial swelling, weakness, posterior paresis, and sudden death. Antifungal therapy was initiated in three neonatal animals but was unsuccessful in each case. All neonates had active mycotic pneumonia caused by Aspergillus fumigatus or Mucor spp. at time of death; four of these animals also had disseminated disease that caused mycotic encephalitis. This case series indicates that fungal disease should be included in the differential diagnosis list of any pudu presenting for neurologic or respiratory clinical signs.

Abstract
The objective of this study was to describe bacterial culture and antibiotic susceptibility results in 476 dogs presenting with suspected bacterial keratitis in Iowa and surrounding Midwestern states, further detailing trends in patient characteristics, seasonality, and antimicrobial resistance. Corneal swabs yielded 465 bacterial isolates and 220 cultures (46.2%) with no apparent growth (0–5 isolates per culture). The most frequent bacterial genera were Staphylococcus (32.3%), Streptococcus (19.1%), and Pseudomonas (12.5%), while the most common bacterial species were Staphylococcus pseudintermedius (26.7%), Streptococcus canis (12%), and Pseudomonas aeruginosa (7.5%). Compared to mixed-breed dogs, canine breeds most likely to be examined for ulcerative keratitis included Boston terrier, Cavalier King Charles spaniel, miniature pinscher, pug, rat terrier, Saint Bernard, shih tzu, and silky terriers. In summer, the likelihood to yield a negative culture was reduced while the likelihood to culture Pseudomonas species was increased. Bacteria considered multidrug resistant (MDR, resistant to ≥ 3 antibiotic classes) represented 20% of all canine isolates and were most prevalent for Staphylococcus species (33%). An alarming, escalating trend of MDR prevalence was noted between 2016 (5%) and 2020 (34%). Individual ophthalmic preparations (i.e., single antibiotics or commercially available antibiotic combinations) with highest efficacy against all bacterial isolates included chloramphenicol (83%), ceftiofur (79%), amikacin (77%), neomycin-polymyxin B-bacitracin (77%), and gentamicin (74%). Efficacy of systemic antibiotics and combinations of ophthalmic preparations was also evaluated. Based on the present findings, triple antibiotic (Neo-Poly-Bac) is recommended as empirical monotherapy for prophylactic antibiotic therapy in dogs with simple corneal ulcers, while a chloramphenicol-ciprofloxacin combination is empirically recommended for therapeutic management of infected corneal ulcers. Pending culture and susceptibility results, appropriate selection of empiric antibiotic therapy is important to enhance therapeutic outcome and reduce antibacterial resistance in dogs with corneal ulceration.

Abstract
Curvularia spp. are globally distributed saprophytic fungi, classified in the literature as dematiaceous, or darkly pigmented fungi. These fungi have been increasingly recognized as causing cutaneous, ocular, respiratory, and central nervous system infections in humans, but have been infrequently documented as pathogens in the veterinary literature. A 5-yr-old male Chinese goral (Naemorhedus griseus) presented with bilateral fungal dermatitis of the pinnae, and subsequent pyogranulomatous rhinosinusitis. Clinical signs included epistaxis, mucosanguineous nasal discharge, and dyspnea. Sequential histologic examinations of cutaneous and nasal lesions revealed pyogranulomatous inflammation with extracellular and phagocytized nonpigmented yeasts. Fungal culture and polymerase chain reaction identified Curvularia sp. The absence of pigmentation in tissue in this case suggests that pigmentation may not be a consistent histologic finding for this fungus, emphasizing the importance of molecular identification to prevent misidentification. Despite intensive interventions in this goral, the disease progressed, and was ultimately fatal.

Abstract
An 8-year-old castrated male Bichon Frise was presented to the Kansas State University Veterinary Health Center for evaluation of unilateral right-sided exophthalmos, suspected secondary to a retrobulbar abscess. The dog had acutely developed right-sided periorbital swelling, exophthalmos with pain on retropulsion, as well as multiple cutaneous exudative plaques on the feet and tail base. On ophthalmic examination, the dog also exhibited mild left-sided exophthalmos with decreased, nonpainful retropulsion. Orbital ultrasound and CT were performed to evaluate the extent of bilateral orbital disease. Incisional biopsies were obtained from the affected right periorbital tissues and skin of the feet, and histopathology revealed severe neutrophilic inflammation of the dermis with no organisms detected. Histologic changes were consistent with sterile neutrophilic dermatosis. The dog achieved clinical remission following treatment with initial immunosuppressive doses of corticosteroids and subsequent long-term maintenance therapy using oral cyclosporine.

Abstract
This case series describes the ocular, clinical and histologic manifestations of disseminated Aspergillosis in two dogs. Two dogs presented for severe unilateral panophthalmitis and secondary glaucoma with positive Aspergillus spp. titers. Case 1 showed no clinicopathologic systemic symptoms of fungal dissemination, however, case 2 was affected with acute renal failure. The affected eye of case 1 did not respond to medical therapy and was enucleated for comfort. The affected eye of case 2 responded to aggressive topical and systemic medical therapies, however, the patient was euthanized for acute renal failure. Globes were collected for histologic evaluation at the time of death. Histology of both revealed panophthalmitis with presence of significant intraocular hemorrhage, multifocal fungal granulomas, retinal and optic nerve changes consistent with secondary glaucoma, rupture of the anterior lens capsule, and fungal invasion and colonization of the intralenticular space. These cases represent a unique and devastating ocular manifestation of disseminated Aspergillosis. Cases presenting with uveitis and secondary glaucoma of unknown origin, especially with confirmed or suspected lens capsular rupture, should have serologic testing for this infectious agent.

Abstract
This report describes the clinical presentation, diagnosis, histologic lesions, and outcome of endogenous mycotic endophthalmitis secondary to candiduria in a three-year-old female spayed Dachshund. The dog was being treated for Evans syndrome for one month prior to being diagnosed with candiduria and fibrinous uveitis OS. The left eye was enucleated due to secondary glaucoma, and the fungal urinary tract infection was treated successfully. Uveitis developed in the contralateral eye with relapse of the urinary tract infection in the following weeks. The right eye was medically managed until secondary glaucoma developed and was subsequently enucleated. Histopathology of both eyes showed evidence of endophthalmitis with intralesional fungal organisms, consistent with Candida spp. Ocular candidiasis is rare in dogs. To the authors' knowledge, this is the first report of endogenous mycotic endophthalmitis with concurrent candiduria in a dog.

Abstract
Disseminated Chrysosporium spp. infection was diagnosed in a German shepherd dog based on a positive fungal culture and cytological findings of intralesional fungi associated with granulomatous splenitis and neutrophilic lymphadenitis. The clinical presentation that could mimic a multicentric lymphoma, including markedly enlarged lymph nodes and a very abnormal splenic appearance on ultrasound makes this case even more atypical. The patient showed rapid clinical improvement on oral posaconazole and remains clinically stable ten months after diagnosis.

Abstract
A 13-year-old female Lhasa Apso was presented for blepharospasm and conjunctival hyperemia of the right eye. Ophthalmic examination revealed an anterior stromal ulcer associated with a raised yellow corneal plaque. In vivo confocal microscopy and cytology of the cornea identified neutrophilic inflammation and yeast cells. Malassezia pachydermatis was isolated from a corneal scraping. Treatment with topical voriconazole ophthalmic solution resolved the keratitis.

Abstract
This report describes the clinical presentation, diagnosis, and medical management of a 2-year-old spayed female dwarf rabbit (Oryctolagus cuniculus) suffering from an ulcerative keratitis and a stromal abscess with a rapid evolution. The diagnosis of fungal keratitis was based on fungal culture identifying the pathogen as Aspergillus fumigatus. Treatment by topical terbinafine was efficacious in resolving the keratomycosis within 8 weeks. To our knowledge, this is the first reported case of spontaneous keratomycosis in a rabbit and the first description of successful therapy by terbinafine.

Abstract
Five cases of canine keratomycosis were diagnosed and treated at a private Veterinary Ophthalmology Practice in Melbourne, Australia. Clinical presentations varied between dogs. Predisposing factors were identified in 4 of 5 cases. Diagnostic modalities utilized were corneal cytology and fungal culture. Corneal cytology confirmed the presence of fungal organisms in all five cases. Aspergillus, Scedosporium, and Candida were cultured from three cases, respectively. Specific antifungal treatment included 1% voriconazole solution or 1% itraconazole ointment. Keratectomy and conjunctival grafting surgery was performed in two patients. Resolution of infection and preservation of vision were achieved in 4 of 5 patients.

Abstract
OBJECTIVES To review clinical data on dogs that suffered a corneal and anterior segment foreign body (CASFB) trauma and to determine the risk factors for foreign body (FB) trauma and subsequent enucleation. ANIMALS STUDIED Dogs with CASFB presented to the Animal Health Trust (AHT) from January 2000 to December 2012. PROCEDURES Clinical data for CASFB cases were compared to those available for the remaining AHT ophthalmic population over the same period. The depth of the FB trauma was divided into five categories. The type of FB and method of removal were described for each category. The degree of secondary uveitis and lens involvement was graded and correlated with subsequent enucleation. RESULTS The mean age (standard deviation) of 218 identified CASFB cases was 3.96 (2.95) years. Risk factors for CASFB trauma were dogs younger than 5 years, English Springer Spaniels, Labrador Retrievers, and working dogs. Most dogs required general anesthesia for FB removal, and hypodermic needles were the most commonly used instrument. The lens was involved in some cases with a full-thickness CASFB trauma (n = 49, 45%), but most suffered a minor lens trauma (n = 37, 76%). The lens trauma and phacoclastic uveitis were managed medically in most dogs (n = 37, 76%), and phacoemulsification was only elected as initial treatment in some dogs (n = 10, 20%). Enucleation was required overall in 6% of dogs. Statistically significant associations were found between enucleation and depth of FB trauma, degree of uveitis, and severity of lens trauma (P < 0.001). CONCLUSIONS Young dogs, English Springer Spaniels, Labrador Retrievers, and working dogs had an increased risk of CASFB trauma. Risk factors for enucleation were full-thickness FB penetration, severe lens trauma, and severe uveitis.

Abstract
Corneal emergencies can be due to a number of different causes and may be vision threatening if left untreated. In an attempt to stabilize the cornea, it is of benefit to place an Elizabethan collar on the patient to prevent further corneal damage. This article discusses the diagnosis, prognosis, and management of corneal emergencies in dogs and cats.
