The water buffalo (Bubalus bubalis), also known as the Asian buffalo, is an essential domestic bovid. Indeed, although its world population (~209 million heads) is approximately one-ninth that of cattle, the management of this species involves a larger human population than that involved with raising cattle. Compared with cattle, water buffalo have been understudied for many years, but interest in this species has been increasing, especially considering that the world population of these bovids grows every year—particularly that of the river buffalo. There are two genera of buffalo worldwide: the Syncerus (from the African continent), and the Bubalus (from the southwest Asian continent, Mediterranean area, southern America, and Australia). All species belonging to these two genera have specific chromosome numbers and shapes. Because of such features, the study of chromosomes is a fascinating biological basis for differentiating various species (and hybrids) of buffaloes and characterizing their karyotypes in evolutionary, clinical, and molecular studies. In this review, we report an update on essential cytogenetic studies in which various buffalo species were described from evolutionary, clinical, and molecular perspectives—particularly considering the river buffalo (Bubalus bubalis 2n = 50). In addition, we show new data on swamp buffalo chromosomes.

The present study was carried out to describe the clinical picture of traumatic reticuloperitonitis (TRP) in water buffalo (Bubalus bubalis) and to evaluate the inflammatory and immunologic responses for this clinical condition. Twenty-two buffalo with acute local TRP were monitored in our study. Additionally, 10 clinically healthy buffalo were randomly selected and served as controls. Acute local TRP was initially diagnosed by clinical examination and confirmed by ultrasonographic (USG) examination and/or necropsy findings. Blood samples were collected from all examined buffalo to measure the respective levels of tumor necrosis factor alpha (TNF-α), interleukin (IL)-1β, IL-6, IL-10 and interferon gamma (INF)-γ, serum amyloid A (SAA), C-reactive protein (CRP), haptoglobin (Hp), fibrinogen (Fb), and serum sialic acid (SSA). It was found that TNF-α, IL-1β, IL-6, IL-10, SAA, CRP, Hp, Fb, and SSA were significantly higher in buffalo with TRP than the controls. Our findings suggest that the examined immunologic variables were helpful in documenting the inflammatory response in buffalo with TRP. However, their diagnostic usefulness only becomes apparent when considered in tandem with the clinical findings for any given animal, its anamnesis, and a subsequent USG assessment. Due to the frequent complications of TRP, more accurate indicators of its occurrence and severity would be useful.

<p>Two albino water buffalo affected by multiple melanocytic tumors in Southern Brazil are described. Grossly, there were multiple dark tumors within the skin, skeletal muscle, lungs, and lymph nodes. The tumor was also present in the pericardial sac, renal capsule, mediastinum and pleura. Microscopically, the tumors consisted of polyhedral epithelioid cells arranged in solid nests or interwoven fascicles supported by a thin and sparse collagenous stroma. The cytoplasm was eosinophilic and sometimes contained varying amounts of melanin pigment. The mitotic rates were low. Immunohistochemistry staining with Tyrosinase, Melan-A, Vimentin, S-100 protein, and neurofilament were positive. It is possible that the polymorphisms related to pigmentation in albino buffalo contributed with a high risk of developing melanoma as suggested in humans.</p>

The reversal of epidural xylazine, induced with IV atipamezole was evaluated in 15 buffaloes. Atipamezole at different dose rates (5, 10 and 15 µg/kg) injected 30 minutes after epidural xylazine provoked visible signs of arousal shortly after inection in all buffaloes without any side effects. The mean arousal times were 4.8±0.84 min, 2.4±0.24 min and 2.0±0.00 min while the mean total recovery times were 61.0±2.6 min, 33.0±3.7 min and 32.0±4.3 min following doses of 5, 10 and 15 µg/kg atipamezole respectively. The heart, respiratory and ruminal rates were mildly influenced. Overall, the IV atipamezole at a dose rate of 10 µg/kg was found effective and satisfactory for reversing the analgesic, sedative and cardiopulmonary depression effects induced by epidural xylazine administration in buffaloes.
