Liver infections due to amphistomes in buffaloes cause significant economic losses in livestock sector. The present study investigated the classical morphological features of adult amphistomes combined with histopathology and molecular identity in slaughtered buffaloes from Khyber Pakhtunkhwa, Pakistan. Adult amphistome were collected and morphologically characterized as Gigantocotyle explanatum. Morphometric measurement (n=50) were obtained with 12.05+-1.68 mm in length and 5.77+-0.81 mm in width, and the values of sagittal section was 6.35+-1.03 * 2.98+-0.50 mm in size. Severe bile duct pathology was observed with fibrosis of the duct wall with an irregular epithelial border, hyperplasia and inflammatory response with numerous neutrophils and eosinophils. The molecular identity of G. explanatum within Paramphistomidae was confirmed by ITS-2 rDNA sequences phylogenetic analysis based on maximum likelihood method. The genetic data based on ITS-2 secondary structure of G. explanatum consisted of four helix, Helix I, II and IV were conserved as compared with other closely related reference taxa of family Paramphistomidae and Gastrothylacidae. Helix III expressed some variations. The study concluded that rDNA ITS-2 and secondary structure information provides a guide for other researchers to determine the molecular taxonomic position of Paramphistomidae trematodes, data will support future clinical studies and control measures to reduce the amphistomiasis in buffaloes.

The present study was designed to investigate histopathological changes of endometritis in 110 slaughtered buffaloes from local abattoir in Junagadh (Gujarat). Grossly, 44 genitalia exhibited thickening of uterine wall and presence of varying degree of mucopurulent/purulent exudate noted in 18 uterine samples. Histopathologically, the lesions observed were acute, subacute and chronic changes in 25.45 percent, 20.90 percent and 34.55 percent respectively. Acute endometritis was characterized by severe congestion along with marked stromal edema, degenerative changes and focal denudation of luminal epithelium, focal hemorrhage in sub epithelial zone, infiltration of inflammatory cells predominantly polymorphonuclear cells and mononuclear cells in lamina propria, infiltration of mononuclear cells in glandular lumina and peri-endometrial glands. Subacute endometritis consisted of denudation of luminal epithelium, congestion, stromal edema and Focal haemorrhagic spot, infiltration of mononuclear cells in lamina propria, glandular lumina and around atrophied endometrial gland, glandular dilation, hyperplasiaof mucosal epithelium, atrophy of endometrial glands and thickening of blood vessels. The main features of chronic endometritis were desquamation of mucosal epithelium, infiltration of mononuclear cells and plasma cells in sub epithelial zone, dilatation of endometrial glands with degenerative changes, infiltration of mononuclear cells in glandular lumina and periglandular region with narrowing of glandular lumina, perivascular and periglandular fibrosis leading to severe thickening of blood vessels resulting in narrowing of their lumina and transformation of endometrial epithelial cells into low cuboidal against the normal columnar epithelium. Beside the above histopathological lesions three uterine samples revealed adenomyosis and twenty two genitalia showed metritis.

This report describes a case of laryngotracheaoesophageal compression due to giant benign hyperplastic thyroid in a Jaffarabadi buffalo and thyroidectomy to relieve from compressive symptoms. Physical, radiographical and ultrasonograhical findings confirmed enlarged thyroid. Under sedation and local analgesia, total thyroidectomy was performed via cervical midline approach and excised thyroid was submitted for urther histopathological examination. Animal had an uneventful postoperative course and recovered well. Grossly, excised thyroid was of 30 cm * 10 cm in size and 850 g of weight. Both the lobes of the thyroid gland were symmetrically enlarged and had meaty appearance. Benign hypertrophy and hyperplasia was reported on the histopathological report of surgical specimen.
