Coccidiosis is one of the most important parasitic diseases in the poultry industry, which is caused by the Eimeria and Cryptosporidic species. The main goal of current study was to investigate the prevalence of different Eimeria species in indigenous poultry of Behbahan, Khuzestan province, south west Iran. Fecal samples were collected randomly in all of the 100 native birds from 11 villages in this region. Number of oocysts per gram of faeces (OPG) was determined by the standard McMaster technique. Identification of oocysts was done on sporulation in 2.5 % potassium dichromate solution. The results showed an overall prevalence of 20% for Eimeria sp. Infection Contains 15%; E. acervulina (80%), E. maxima (60%), E. brunetti (53.3%), E. tenella (33.3%) and E. mitis (26.6%) with mixed infections of E. maxima +E. acervulina (40%), E. tenella+E. brunetti +E. maxima (46.6%), and E. brunetti +E. maxima + E. tenella (2.2%) +E. mitis (13.2%) were determined. In order to determine the rate of Cryptosporidium infection, the samples were first stabilized using 70% methanol and stained under the Modified Zeheil Neelsen method. They were examined using an optical microscope. From the obtained spreads, 8 samples (8%) have been recognized as positive. This is the first report of coccidiosis in native birds in this region.This diseases may be an important factors in the economic losses of the native and broiler chickens in this region.Further additional research and design control strategies for improving management farms are necessary.

Acute phase proteins (APP) are a class of serum protein concentration in response to inflammation, trauma, and neoplasia increases significantly. Haptoglobin (HP) is one major positive acute phase proteins, that have low concentration in the serum of healthy animals, but with its concentration increase over 100- fold on stimulation. Concentration remained high for about 24-48 hours and during the recovery phase begins to decrease rapidly. In order to determine the reference range for serum haptoglobin concentration camels Iranian dromedary camels jugular vein sixty Iranian Central aged one to five years in both sexes were taken in the spring and summer of 1389. Blood samles were collected from jugular vein and haptoglobin value was measured by using colorimetric method with Ireland commercial kits. Age and sex had no significant effect on the haptoglobin value of clinically healthy Iranian dromedary camels (p>0.05). There was no significant correlation between age and serum haptoglobin concentrating in Iranian doromrdary camels (p>0.05). Reference value of serum haptoglobin in clinically healthy Iranian dromedary camels (Camelus dromedarius) was 0.54-1.04 mg⁄ml (mean ±SD =0.79± 0.128).

Hydatid cyst and fasciolosis are zoonotic diseases without a specifc clinical sign. Final diagnosis in animals can be made only by necropsy and post mortem insepction. Undoubtedly, hygiene of slaughterhouses has upstanding correlation with Community hygiene and health, fewer no attentions to this subject will follow more hazards to the people of society. Total liver and lungs of the slaughtered Sheep and goats in Gachsaran slaughterhouse were studied .Overall 3082 of sheep cases and 7873 goat cases slaughtered in summer season. A total of 11753 of liver and lung studied, 1153 samples deleted and out of consume cycle. The results showed that liver of sheep and goat infected (9.99% Fasciola, 6.20% hydatid cyst, abscess 3.46%); (9.27% Fasciol ,9.60% hydatid cyst, 3.91% abscess) respectively, (12.86% Pnemonia and permia, 4/96% hydatid cyst, 5.81% abscess); (16.98% pnemonia and permia, 4.76% hydatid cyst, 12.14% abscess) obtanined in lung of sheep and goats respectively. As a conclusion, so more attention of related control organizations seems to be needed.

The most important and common disease among dairy cows is mastitis and it is still a big challenge for the dairy industry all over the world.Oxidative stress induced by reactive oxygen species(ROS) is a major cause of different diseases especially mastitis in cattle.there are few studies on the role of ROS in occurrence of subclinical mastitis.the objective of the persent study was to evaluate the changes in plasma malondialdehyde concentrations as a marker of lipid peroxidation of red blood cells and its relationship with somatic cell count(SCC) in milk as the marker of mammary inflammation in cattle.Heparinized blood and milk samples were collected from 45 healthy cows and 45 cows with subclinical mastitis from dairy farms in Tehran province,Iran.No significant difference (p>0.05) was seen between concentrations of malondialdehyde in the studied groups.there was a significant difference (p<0.001) between SCCs in the healthy cows with subclinical mastitis.the concentration of plasma malondialdehyde was higher in cows with subclinical mastitis which indicates mild increase in production of ROS in response to invading pathogens.

Subclinical mastitis is considered as one of the most prevalent diseases in dairy cows، causing drastic loss in the dairy industry. Oxidative stress، induced by reactive oxygen species (ROS)، is believed to be a primary factor in various cattle diseases including mastitis، but there are few studies regarding the role of ROS in subclinical mastitis. This study was undertaken to i) study the changes in activities of erythrocyte glutathione peroxidase (e-GSH-Px) and its functional component، selenium (Se); ii) compare the activities of erythrocyte superoxide dismutase (e-SOD) and its functional components، Cu and Zn in cows with subclinical mastitis and normal cows. Milk and heparinized blood samples were collected from 45 normal cows and 45 cows with subclinical mastitis from dairy cows in Tehran province، Iran. Somatic cell counts (SCC)، activities of GSH-Px and SOD and concentrations of Cu، Zn and Se were measured. No significant difference (P>0. 05) was shown between GSH-Px and SOD activities and also between the concentrations of Cu and Zn in the studied groups. There was a marginal significant difference (P=0. 05) between the Se concentrations in the normal cows and cows with subclinical mastitis. The correlation between SCC and SOD was positive and significant (P<0. 05). It was concluded that optimum antioxidant intake in the feed may enhance the resistance against subclinical mastitis.
