RESUMO
Cat cafés have gained significant popularity worldwide, offering a unique interface between humans and cats. The present study aims to assess the prevalence of potentially zoonotic endoparasites and dermatophytes from cats living in cat cafés situated in the Bangkok metropolitan area in 2017-2018. Cat fecal samples were subjected to microscopic examination employing centrifugal flotation and centrifugal sedimentation techniques. The hair samples from every cat were cultured on a dermatophyte test medium and Sabouraud dextrose agar and subsequently confirmed by visualization of the typical colony and macroconidia morphology. Findings from 11 cat cafés indicated an 18.2% (2/11) prevalence of gastrointestinal parasites, including Toxocara spp., Ancylostoma spp., Physaloptera spp., and Eucoleus aerophilus. Dermatophytes were prevalent in 16.2% (32/198) of the total number of cats tested, with Microsporum canis being the sole species identified. Notably, the presence of dermatophyte was significantly correlated with the presence of skin lesions and the cats' origin. In summary, the findings of this study have provided evidence of potentially zoonotic endoparasites and dermatophytes in cats residing in cat cafés. Therefore, it is imperative to heighten awareness and encourage preventive measures among cat café owners and customers to halt the dissemination of these pathogens.
RESUMO
Arterial thromboembolism (ATE) in cats usually relates to cardiogenic causes that can be diagnosed by conventional echocardiography. Two-dimensional speckle-tracking echocardiography (2D-STE) is a new ultrasound modality with higher sensitivity. Our objective was to investigate left atrial myocardial deformation in cats with both cardiogenic and non-cardiogenic ATE and normal cats using 2D-STE. Twenty-three normal cats and 21 cats with ATE cats were recruited and performed conventional echocardiography and 2D-STE. From the results, left atrial (LA) strain and strain rate from 2D-STE were significantly decreased in cats with cardiogenic ATE (P < 0.001), but there was no significant difference in non-cardiogenic ATE compared with normal cats. From the correlation test, the use of left atrial strain during the reservoir phase (LASr) could represent the overall LA deformation. The intra- and inter-observer coefficient of variation of LASr was less than 15%. The logistic regression revealed that the LASr value of less than 11% was a significant factor for the occurrence of ATE (odd ratio = 189.0, P < 0.001). In conclusion, LASr derived by 2D-STE is a repeatable and non-invasive technique to assess LA myocardial deformation in cats with ATE. By 2D-STE, impaired LA function was detected in cats with cardiogenic ATE. LASr < 11% may use as a predictor of the risk of ATE occurrence in cats.
RESUMO
Fluid analysis is an initial approach for determining the underlying causes of body cavity effusions. Modified transudate is commonly diagnosed in pleural effusion in cats, however, it provides limited diagnostic information. Aims of this study were to investigate common etiologies causing different pleural fluid types and to evaluate the usefulness of lactate dehydrogenase (LDH) for differentiating the etiology in modified transudates in cats. Pleural effusion samples from 122 cats were analyzed and classified into three types: transudate, modified transudate, and exudate. Causes of pleural effusion were classified into four conditions: cardiac disease, neoplasia, feline infectious peritonitis (FIP), and pyothorax. The relationship of underlying etiology and fluid types was described. The LDH levels in pleural fluid and plasma were compared between the causes in the samples classified as modified transudate. The fluid analysis of pleural effusion showed that modified transudate was the most common fluid type (44.2%). Neoplasia was predominantly diagnosed (38.5%) as the etiology of pleural effusion. There was no significant correlation between pleural fluid and plasma LDH level in any type of pleural fluid, suggesting that pleural fluid LDH does not appear to be affected by plasma LDH. The occurrence of modified transudate was not associated to its etiologies, however, the LDH level in modified transudates showed significant differences between etiologic groups. The LDH level in modified transudate was excellent in separating cardiac from non-cardiac diseases with a cut-off value of <535 U/L and separating FIP from non-FIP diseases with a cut-off value of >641 U/L. Based on the current findings, pleural fluid LDH can be a useful adjunctive marker for differentiating some causes of modified transudate pleural effusion and should be added in the routine diagnostic work-up of feline patients with pleural effusions.
RESUMO
Background: Canine non-infectious deep ulcerative keratitis is considered a severe ocular disorder that possibly can progress to perforation. Immediate treatment should be directed to stimulate corneal wound healing, control infection, and minimize self-trauma while eliminating the underlying causes. Aim: This retrospective study was aimed to compare the difference in non-infectious deep corneal wound healing time between cases treated with medical therapy alone and those treated with medical therapy combined with a nictitating membrane flap. Methods: The medical records at the Ophthalmology Clinic, Small Animal Teaching Hospital, Faculty of Veterinary Science, Chulalongkorn University between January 2018 and March 2020 were retrospectively reviewed. Sixty-six eyes (from 65 dogs) diagnosed with non-infectious deep ulcerative keratitis from the medical treatment group (n = 34) and the combined treatment group (n = 32) were included. The combined treatment group was prescribed the same conservative medical administrations plus a surgical nictitating membrane flap for 14 days. Results: Healing time was defined as the duration of time from the day that the dog had been diagnosed with deep ulcerative keratitis by a fluorescein staining test to the day that the corneal fluorescein stain was negative. Overall, the mean age of dogs with deep ulcerative keratitis was 10.49 ± 4.7 years. The disease was commonly evident in females more than males. Shih Tzu was the most prevalent dog breed. The corneal healing time between dogs receiving medical therapy alone and those receiving combined treatment was not statistically significant (p = 0.386). Healing times were not significantly different between sex and breed (p = 0.41). The median corneal healing time for dogs older than 10 years in the combined treatments group (29.5 days; ranging from 20 to 46 days) was longer than for those receiving medical therapy alone (21 days; ranging from 9.5 to 30.5 days). Conclusion: Supportive therapy including a nictitating membrane flap is suggested in dogs prone to deep corneal ulcers not involving infection. Even though the healing time is not statistically significant, a nictitating membrane flap acts as a tissue bandage to reduce friction over the cornea, and it also alleviates the healing process by moistening the ocular surface.

Feline arterial thromboembolism (ATE) is a condition with a high mortality rate. Acid-base abnormalities may be beneficial to the prognosis of cats with ATE. Venous blood gas and electrolytes data on the first day of ATE presentation of 47 cats with ATE were retrospectively reviewed and analysed. The Cox and logistic regression were analysed to evaluate the relationship between acid-base parameters and death. The most common venous acid-base disorder was simple metabolic acidosis. Age, body weight, and partial venous pressure of carbon dioxide (PvCO2) differed between the dead and alive groups within 7 days of the onset of ATE presentation (p < 0.05). Cox-regression showed that increasing age (HR=1.175 [95% CI: 1.027-1.343], p = 0.019), increasing PvCO2 (HR=1.066 [95% CI: 1.010-1.125], p = 0.021) and PvCO2 more than 34 mmHg (HR=7.878 [95% CI: 1.036- 59.915], p = 0.046) were associated with increased hazard of death. Multivariable logistic regression showed that age > 5 years (OR=9.030, 95% CI: 1.258- 64.823; p=0.029), and PvCO2 > 34 mmHg (OR=21.764, 95% CI: 1.747-271.141; p=0.017) were associated with an increased risk of death, while concomitant administration of enoxaparin with clopidogrel (OR=0.111, 95% CI: 0.015-0.795; p=0.029) were associated with a decreased risk of death within 7 days of the onset of ATE presentation. This study demonstrated the power of venous blood gas analysis which may be used as prognostic indicators for cats with ATE.
RESUMO
The prevalence of enteric parasites in cats in metropolitan Bangkok has not been updated in over 13 years. The main objectives of this study include updating the prevalence of endoparasitism in client-owned cats, status of retroviral infections and determining the association between feline hookworm infection and possible risk factors. A total of 509 fecal samples were collected from client-owned cats in 2014-2015 and examined by a wet fecal mount technique. If additional sample remained, a PBS-ethyl acetate sedimentation was done (n = 229), and ZnSO4 centrifugal flotation was also performed if there was sufficient remaining sample (n = 105). At least one parasite was observed in 32.0% (163/509) of cats, with Ancylostoma being the most common intestinal parasite detected in 21.6% (110/509) of cats. Other parasitic infections detected by fecal examinations included Toxocara (6.9%; 35/509), Platynosomum (3.7%; 19/509), Cystoisospora (3.5%; 18/509), Taenia (2.9%; 15/509), Spirometra (1.6%; 8/509), Dipylidium (0.4%; 2/509), and Opisthorchis-like trematode (0.2%; 1/509). Examination for Giardia infection was conducted with the SNAP® Giardia Test, a coproantigen test, on a subset of the fecal samples (233/509) and revealed a positive result on 3.9% (9/233) of samples. Plasma samples were analyzed using the SNAP® Triple Test detecting antigens of Feline Leukemia Virus (FeLV) and Dirofilaria immitis while also detecting antibodies to Feline Immunodeficiency Virus (FIV). Antigens of FeLV and antibodies to FIV were found in 7.1% (19/269) and 5.2% (14/269) of cats, respectively. None of the cats were found to have circulating antigen of Dirofilaria immitis using this test. No association between retroviral and endoparasitic infections was found. From multivariable logistic regression examining associated factors, the ability of cats to access the outdoors (adjusted OR = 3.22, 95% CI; 1.42-7.87) and having tapeworm segments or adult helminths in feces (adjusted OR = 3.31, 95% CI; 1.34-8.21) were significantly associated with the finding of hookworm eggs in feces. This work presents the most up-to-date data on enteric feline parasite prevalence in the metropolitan Bangkok area from which fecal samples were directly collected from cats. Consequently, this study emphasizes that diagnosis of parasitic infections and the routine use of antiparasitic medications should be encouraged by veterinarians and to owners in order to reduce the reservoir of potentially zoonotic parasites.

BACKGROUND: Positive health implications of early recognition of calcium oxalate (CaOx) urolithiasis include increased opportunity for nonsurgical removal, early dietary modification to minimize urolith growth, early removal to avoid urinary obstruction, and early recognition of genetic and metabolic diseases before they contribute to additional morbidity. OBJECTIVES: To identify high- and low-risk dog breeds for CaOx uroliths and to determine the relationship of age and sex to the development of CaOx uroliths. ANIMALS: Calcium oxalate urolith submissions between 2010 and 2015. METHODS: A comparative cross-sectional study was conducted to identify high- and low-risk breeds for CaOx uroliths by comparing cases to multiple comparison groups. At-risk breeds were identified if odds ratios were significant (P value <.05) across all comparison groups. RESULTS: Of 258 898 urolith submissions, 124 285 were CaOx. Calcium oxalate was identified in 212 breeds. Twelve breeds were identified as high-risk breeds, and 14 breeds were identified as low-risk breeds. All high-risk breeds were small dog breeds, and all low-risk breeds were medium to large dog breeds. Overall, the mean age ± standard deviation of the first CaOx urolith was 8.4 ± 2.8 years. CONCLUSIONS AND CLINICAL IMPORTANCE: To achieve the health benefits of preclinical evaluation, breeds at high risk for CaOx urolithiasis should be screened at 5 to 6 years of age, which is 2 to 3 years before likely development of clinical urolithiasis.

The cross-sectional study described the epidemiology of 8560 canine urolith submissions from Thailand to the Minnesota Urolith Center between January 2009 and December 2015. The frequency of urolith types, the relationships between urolith type and breed, sex, and neutered status, and change of annual submission proportion over the study period were analyzed. Struvite was the most common canine urolith (44%), and was commonly found in intact females with a mean age of 6.3±3.1years. Calcium oxalate was the second most common (27%), more frequently found in intact males with a mean age of 8.8±3.3years. Compound, purine, cystine, calcium phosphate, and silica urolith were less common. During the study period, the proportion of struvite urolith significantly decreased from 48% in 2009 to 39% in 2015 (p<0.001). The proportion of CaOx increased from 21% in 2009 to 32% in 2015 (p<0.001). The results of this study can help veterinarians predict urolith composition to select diagnostic tests and to initiate therapy prior to urolith removal.
