species are the obligate tissue protozoan parasites of livestock causing clinical and subclinical disease resulting in downgrading of the meat and their products thereby leading to economic losses. The present study reveals the prevalence and distribution of sarcocystosis in water buffaloes () slaughtered at local abattoirs in A.P for a period of 1 year from June 2014 to May 2015. A total of 137 buffalo carcasses were screened grossly and microscopically organ wise viz., esophagus, tongue, heart, diaphragm and intercostal muscles. Out of 137 screened, 91 were infected with an overall prevalence of 66.42 %. Age wise analysis of 89 young male calves aged about 18-36 months old revealed 65.16 % (58/89) and 48 old she buffaloes (5-8 years) showed 68.75 % (33/48). The organ wise prevalence was highest in esophagus (51.82 %) followed by tongue (47.44 %), heart (29.92 %), diaphragmatic muscles (28.46 %) and intercostal muscles (18.24 %), respectively. Morphometric studies revealed the presence of two species, i.e., and infection with a prevalence of 43.79 and 22.62 %, respectively, along with mixed infection rate of 43.06 %. Microscopic studies of showed sarcocyst length/width/cyst wall thickness ranged between 0.31-0.69/0.09-0.12 mm/<1 µm, respectively, and bradyzoites with an average of 6.25 µm length/2.5 µm width. Similarly, cyst ranged between 2 and 8.5 mm/1-3 mm/2-5 µm and bradyzoites with an average of 10 µm length/2.5 µm width. The histopathological studies revealed congestion and degenerative changes of myocytes along with infiltration of mononuclear cells.

A study was conducted to determine the prevalence of microfilariasis and analysis of diagnostic methods in buffaloes at Veterinary Poly Clinic, Gudiwada with relation to season, age and breed for a period of 1 year (March 2011-February 2012.Out of 1,222 blood smears examination, only 123 samples were found positive for microfilariasis with a prevalence rate of 10.06 %. Highest prevalence was observed in monsoon (12.54 %) followed by summer (9.18 %) and least in winter (7.05 %). Buffaloes above 9 years age were at high risk with a prevalence rate of 12.5 %, followed by 3-9 years (10.7 %) and below 3 years age (6.09 %) respectively. Breed wise prevalence of microfilariasis was higher in graded murrah buffaloes 10.87 % compared to non-descripts (6.19 %). Three commonly used diagnostic techniques viz. Modified Knott's Technique, thick blood smear examination and wet film examination were done to evaluate comparative sensitivity/efficacy. Among these techniques, 100 % efficacy was observed in Modified Knott's Technique and 86.99 % in thick blood smear examination followed wet film examination 78.04 % respectively.

The present paper reports a case of pulmonary mucormycosis in a 19 wk layer bird that was presented for necropsy to the Department of Veterinary Pathology, NTR College of Veterinary Science, Gannavaram. Mycotic pneumonia in poultry is commonly due to Aspergillus spp and due to others like Mucor spp is very rare. On postmortem examination, the lungs were enlarged, consolidated with multiple greyish white nodules. Histologically, the lung sections revealed pyogranulomatous lesions with branched aseptate hyphae in center of necrosed area that was surrounded by heterophils, macrophages, lymphocytes and multi nucleated giant cells. These fungal hyphae were broad and a few showing right angle and/or irregular branching characteristic of Zygomyces spp. with periodic acid Schiffs reagent
