We describe here a rare case of traumatic myiasis occurred in August 2014, caused by an association of 2 Diptera species, Sarcophaga tibialis Macquart (Diptera: Sarcophagidae) and Lucilia sericata (Meigen) (Diptera: Calliphoridae), in a domestic cat in northern Italy. Species identification was based on adult male morphology. The present case is the first report of S. tibialis as an agent of myiasis in Italy, and also the first ever report of myiasis caused by an association of S. tibialis and L. sericata. The cat developed an extensive traumatic myiasis in a large wound on the rump, which was treated pharmacologically and surgically. The biology, ecology, and distribution of S. tibialis and L. sericata are also discussed. A literature review is provided on cases of myiasis caused by S. tibialis, and cases of myiasis by L. sericata involving cats worldwide and humans and animals in Italy.

A 4-year-old neutered female domestic shorthair cat weighing 5.1 kg was referred to Jeju National University Hospital with acute onset respiratory distress, weakness, and anorexia. The patient had a history of stressful antecedent events that involved bullying by a newly introduced cat. Thoracic radiography and echocardiography revealed a stage C hypertrophic cardiomyopathy phenotype based on the American College of Veterinary Internal Medicine classification system with pulmonary edema, pleural effusion, and pericardial effusion at the same time. The patient was treated with furosemide, pimobendan, and rivaroxaban. Pericardiocentesis was performed because pericardial effusion was identified. Reevaluation after 30 days revealed a normal respiratory rate on physical examination, normal cardiac shape on thoracic radiographs, and normal cardiac measurements on echocardiography. The patient was tentatively diagnosed with transient myocardial thickening (TMT) and all medications were discontinued. Six months after the initial hospitalization, the cat continued to do well without any clinical signs or left ventricular wall thickening. This case is the first report describing feline TMT in Korea. Moreover, it involves a rare case in which pulmonary edema, pleural effusion, and pericardial effusion, which induce cardiac tamponade, occurred simultaneously due to TMT-related congestive heart failure.

A 3.5kg, 3-year-old castrated male Japanese domestic cat withpelvic limb ataxia and dysuria was referred to the Veterinary Medical Center of the Tokyo University. On the neurologic examination findings, both pelivic had a LMN paresis. The cat was FeLV positive and FIV negative. Radiographic findings did not identify the spinal lesions. In magnetic resonance images(MRI) of the lumbar spinal cord, the cat had the lesions in the lumbar(L) 1 and L3, characterized by hyperintensity on a transverse T2-weighted and T1-weighted images, and contrast enhancement was evident. The mass removed by dorsal laminectomy. Histopathological examination of the mass revealed spinal lymphoma. Three weeks after the surgery, the cat administered chemotherapy protocol for lymphoma by current protocol. Two weeks after chemotherapy, the cat had a metastasis to bone marrow and died.

A 1-year-old Korean domestic short-haired cat presented with skin hyperextensibility and a severely macerated wound on the skin of the dorsal part of the neck. Diagnostic studies including histopathology and skin extensibility index revealed congenital cutaneous asthenia (Ehlers-Danlos syndrome). In this cat, the skin wounds and defects were successfully managed with standard wound management and cosmetic surgery. Although skin hyperextensibility is persistent, the cat has lived well without other complications to date. To the best of our knowledge, this is the first report of cutaneous asthenia in a cat in Korea.

Leopard cat (Prionailurus bengalensis euptilurus) is a small wild cat assessed as an endangered wildlife in Korea. There have been very few reports of their diseases. Herein, we describe fibrinous pleuritis caused by Streptococcus canis infection with excessive pleural effusion, hydropericardium, mild ascites, and liver fibrosis in a leopard cat. S. canis is a commensal microflora in domestic cats and often affects the upper respiratory tract inducing chronic and severe respiratory diseases. However, there is no literature regarding the S. canis in leopard cats. Therefore, we first report fibrinous pleuritis associated with an S. canis infection in a leopard cat.

A 7-year-old castrated male domestic short-hair cat presented with anorexia, constipation, depression, and voice alteration. Physical and neurological examinations revealed hyperthermia ($40.5^{\circ}C$), ventroflexion of the neck, reduced responses to external stimuli, generalized muscle weakness, and exercise intolerance. Thoracic radiographs revealed the presence of a cranial mediastinal mass. The history, clinical signs, and other examination results were compatible with acquired myasthenia gravis (MG). Acetylcholine receptor (AChR) antibody titers were determined to confirm MG and the serum AChR antibody concentration was 1.24 nmol/L (reference interval, < 0.3 nmol/L). This is the first diagnosis of acquired MG in a cat in Korea.

A 10-year-old castrated male Domestic Shorthair cat visited a veterinary medical teaching hospital for emergency dyspnea. The cat was hypoxic and hypotensive, and stridorous respiration was remarkable. Visual inspection confirmed laryngeal paralysis and a lack of mobility of the left larynx. Megaesophagus, aspiration pneumonia, cranial mediastinal mass, and positive Tensilon test results using neostigmine were observed, indicating acquired myasthenia gravis secondary to thymic neoplasia. After 10 minutes of neostigmine 0.02 mg/kg IV administration, laryngeal paralysis and dyspnea resolved. Histopathlogical examination for the cranial mediastinal mass after surgical resection confirmed malignant thymoma. Here, we report a case of acquired myasthenia gravis in a cat with a malignant thymoma that presented with life-threatening dyspnea due to laryngeal paralysis. Feline laryngeal paralysis is uncommon, and myasthenia gravis, a cause of laryngeal paralysis in cats, has not yet been reported. Myasthenia gravis should be considered in cats with laryngeal paralysis.

A 5-year-old neutered male domestic short-haired cat presented with acute dyspnea characterized by open-mouth breathing and stridor for 2 days. Direct visualization via laryngoscopy revealed diffuse laryngeal swelling and severe thickening of the vocal folds bilaterally; thus, the upper respiratory tract was obstructed owing to severe edema. Neutrophil infiltration was found on fine needle aspiration of the larynx cytology, and no discrete mass with polyp or neoplasia was identified on diagnostic imaging. The cat was diagnosed with acute obstructive laryngitis, and a tracheostomy tube was immediately installed. After 17 days of treatment with steroids, doxycycline and azithromycin, the swollen larynx gradually improved, and there was no recurrence of laryngitis or respiratory obstruction. A feline upper respiratory polymerase chain reaction panel revealed Mycoplasma felis infection; however, it could not be determined whether it was pathogenic or opportunistic. Herein, we report a case of obstructive laryngitis in a cat. When respiratory obstruction due to acute laryngitis is identified, a good prognosis is expected with rapid and appropriate treatment.

A 3-year-old castrated male domestic shorthair cat was presented with a chief complaint of sudden onset of intermittent seizures occurring five times a day. Physical examination revealed the copper colored iris and loss of menace response at both eyes. Abnormalities of blood works and serum chemistry revealed mild erythrocytosis, severe microcytosis, and threefold increase in ALT activity. Additional liver function tests results were increased bile acid and $NH_3$ concentration. Radiographic study revealed multifocal nodules of the liver and an extrahepatic shunt was noted by ultraonography, which was confirmed by computed tomography as multiple extrahepatic shunts. The cat was scheduled for surgery applying an ameloid ring to occlude the shunt gradually. Diazepam and lactulose were instituted to the patient. However, clinical signs worsened despite medical management with shortened interval of seizures and the patient died due to cardiac arrest.

Background: Infections of cats with Echinococcus granulosus is uncommon because the cat is not part of the parasite life cycle that a carnivorous and another herbivore represent. Nevertheless, it occurs incidentally when eating food or drinking water contaminated with the worm's larva, especially with the presence of the definitive host (dogs), in this case, the infections are concentrated in stray or outside cats. For this reason, this study examined the possibility of cat infection with E. granulosus and diagnosed the common genotype of this infection. Objective: This study examined the possibility of cat infection with E. granulosus and diagnosed the common genotype of this infection. Methods: Four of the 37 cats that had died in different accidents developed cystic echinococcosis (CE). The cytochrome c oxidase subunit I (COX1) gene was initially amplified and sequenced to determine if these cysts belonged to E. granulosus, in beginning. The DNA fragments resulting from sequencing were then compared and aligned with other sequences using the Gene Bank database. Finally, a phylogenetic tree was drawn according to the sequence data obtained from cox1 genes sequencing, and the MEGA 7.0 phylogenetic analysis program was utilized. Results: Four different sequences were deposited in the Gen Bank with accession numbers (ON795961 to ON795964), all of which belong to the G1 genotype. Approximately 84% and 100% of these sequences aligned with G1 (AB622277.1) and G1 (MG722980.1), respectively. Conclusions: G1 is the dominant genotype that causes cat infections, even though the cat's EC infection was incidental.
