  A survey was carried out to detect the overall incidence of histomoniasis in broiler birds in different parts of Mizoram, India. Out of 4000 birds examined, 40 birds were found positive for Histomonas meleagridis revealing 1% infection rate. Heterakis gallinarum was recovered from the caeca of positive birds. Gross lesions were found in caeca and liver. Microscopic examination of stained section of liver tissue revealed numerous circular amoeboid Histomonas meleagridis together with cellular infiltration. The PCR selectively amplified 209 BP of the small subunit ribosomal DNA sequence of Histomonas meleagridis.

  An outbreak of coccidiosis in laboratory rats has been described in this study. Clinically, out of 50 rats, 30 were died after showing symptoms of anorexia, emaciation and diarrhea. Post mortem examination showed the large and small intestine distended with necrotic and sloughed off mucosal epithelial cells with intestinal content. The examination of the gut contents revealed numerous Eimeria oocysts. After sporulation, the oocysts were identified as those of Eimeria nieschulzi. The infection due to Eimeria nieschulzi is confirmed by Polymerase Chain Reaction (PCR) after amplifying partial (~1.6 kb) nuclear 18S rDNA from DNA of E. nieschulzi. The histopathological examination showed severe damage of the lamina propria of the intestinal mucosa with numerous coccidian developmental stages in the epithelium of small intestine. Biochemical analysis of serum from infested rats presented a significant increase in serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST), glucose, total proteins, globulin and inorganic phosphorous while a decrease in alkaline phosphatase and blood urea nitrogen with insignificant changes in potassium, sodium, magnesium and chloride.

  To obtain data on the incidence of lungworm infestation in piglets in different parts of Mizoram of India a survey was conducted during the calendar year 2011-2012 based on clinical and postmortem findings and in addition some biochemical and histopathological changes of affected lungs associated with Metastrongylus elongates infection were performed. The percent prevalence of lung worm infection in young piglets (upto 4-6 months old) was 40%. Clinically, infected piglets were exhibiting chronic and paroxysmal coughing with generalized unthriftiness. Histologically, tips of the lungs were found to be hard and become grayish or whitish. Histopathological studies revealed pulmonary emphysema. The alveolar cellular reaction of the affected lungs showed epithelialization of alveoli with infiltration of round cells, eosinophils, giant cells, fibers and lungworm eggs. Biochemical analysis of serum from infected piglets showed a significant increase in serum Alanine Amino Transferase (ALT), serum glucose, inorganic chloride, potassium and magnesium with a decrease in serum albumin, total protein and alkaline phosphatase with insignificant changes in the serum sodium level. The pork consumption in Mizoram is very high and pigs under four to six months of age showed the highest mortality rate with respiratory signs in different parts of this area during the study period. There was a serious herd problem associated with hypoproteinaemia, hyperglycaemia and reduced growth rate.
