  Studies were undertaken to evaluate the clinical, gross, histopathological and some biochemical parameters in broiler birds suffered from E. necatrix infection in a local broiler farm in the Aizawl district. Clinically, 20 birds out of 100 no. (aged between 4-6 weeks) showed loss of appetite, unthriftiness and bloody diarrhoea with mucus. Postmortem examination revealed anaemic pale musculature, distended small intestine with petechial haemorrhages. Similar changes were also observed in some areas of the large intestine and caecum. Histopathological examination showed severe haemorrhagic enteritis with necrosis and disintegration of glandular epithelial cells. Several schizonts were observed in the epithelial cells along with merozoites, infiltrating neutrophils and eosinophils. Biochemically, the infected broilers presented hypoglycaemia associated with a reduction in liver glycogen level. Biochemical serum analysis of coccidia infected chickens also showed a significant increase (p<0.01) in alanine amino transferase levels (2.9-245.2) and there were also changes in total protein and cholesterol level in the serum.

  A biochemical study was made to elucidate the biochemical composition of the inner wall of oocyst of Eimeria necatrix and then compared with cellular component of the oocyst. In addition to total protein, glucose and cholesterol, several electrolyte components have been estimated in the present study. The investigation also revealed high activity of Alanine and Asparate aminotransferases in the inner wall of the oocyst of Eimeria necatrix. It seems that the biochemical composition and the enzymes in the inner wall of the oocyst of Eimeria necatrix are of significant value for better metabolic processes in Eimeria spp. as well as for better understanding of possible drug-parasite interaction.

  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.

  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.
