Feline hemotropic mycoplasmosis (hemoplasmosis) is an infection of the red blood cells caused by the Mycoplasma haemofelis (Mhf), Candidatus Mycoplasma haemominutum (CMhm), and Candidatus Mycoplasma turicensis (CMt). The existence of Mhf, CMhm, and CMt has been demonstrated in feral cats in Korea using molecular methods, but no clinical cases have yet been reported. This study reports 2 clinical cases of hemotropic mycoplasmosis caused by CMhm and CMt in 2 anemic cats. The first case was a client-owned intact female domestic shorthair cat that presented with fever, pale mucous membranes, and normocytic normochromic non-regenerative anemia. Prior to referral, an immunosuppressive prednisolone dose was administered at the local veterinary clinic for 1 month. The cat was diagnosed with high-grade alimentary lymphoma. Organisms were found on the surface of the red blood cells on blood smear examination. The second case was of a rescued cat that presented with dehydration and fever. The cat had normocytic normochromic non-regenerative anemia. Necropsy revealed concurrent feline infectious peritonitis. Polymerase chain reaction assay targeting 16S rRNA revealed CMhm infection in case 1 and dual infection of CMhm and CMt in case 2. Normocytic normochromic non-regenerative anemia was observed in both cats before and during the management of the systemic inflammation. This is the first clinical case report in Korea to demonstrate CMhm and CMt infections in symptomatic cats.

The activated immune systems with lipopolysaccharide(LPS) were evaluates by ${\gamma}$- globulin levels in domestic cats. Especially, cats were in a stress condition, which was unfamiliar environmental change. Effect of continuous unfamiliar environmental stressor was a diminution of production of serum total globulin auld ${\gamma}$- globulin on feline infectious peritonitis(FIP) vaccination. The ${\gamma}$-globulin production on FIP vaccination more increased in LPS treated 77ups than non-LPS treated group. Also. the ${\gamma}$-globulin production on FIP vaccination was maintained in LPS treated group under stress condition. These results imply that that the ${\gamma}$-globulin can be produced under a stress condition by mitogen like as LPS.

A 2-year-old, intact male, Persian exotic cat, weighing 2 kg with a history of a palpated abdominal mass was admitted to Veterinary Medical Teaching Hospital, Seoul National University. On routine complete blood count (CBC) and serum biochemical analyses, there were anemia and 0.45 of albumin to globulin ratio. A feline infectious peritonitis (FIP) virus antibody test kit was negative. Radiography, ultrasonography and computed tomography (CT) were performed. A markedly enlarged abdominal mass was found. On cytologic examination of this mass, it was diagnosed as alimentary lymphoma or pyogranulomatous inflammation. Chemotherapeutic treatment for intestinal lymphoma was provided for several weeks, but the mass size was increased and clinical signs were not improved. The cat died six days after discontinuing chemotherapy. On postmortem examination, the definitive diagnosis was FIP. This case describes a cat with FIP in which an abdominal tumor had been suspected clinically.

A 15-year-old castrated male Persian (Case 1), an 1.5-year-old castrated male Bengal (Case 2), and an 1.5-year-old spayed female Russian Blue (Case 3) cats were presented with iris-color change and suspicious anterior chamber mass. Complete ophthalmic examination revealed a vascularized or blood tinted mass filling with anterior chamber accompanied by rubeosis iridis, dyscoria, keratic precipitates, and severe aqueous flare. Ocular ultrasonography showed an iridociliary mass with blood flow signal in Case 1. Abdominal ultrasonography also revealed suspicious metastatic involvements of liver and spleen in this cat. Case 2 and 3 were suspected of being infected with feline infectious peritonitis. Topical antibiotic/steroid combinations were prescribed to control the uveitis in all 3 cases, although enucleation was initially considered for palliative pain management in Case 1. Anterior chamber mass had almost completely disappeared after topical medications and uveitis has been successfully managed, remaining in sight, even though ocular hypertension developed 1 month later in Case 1.
