Study on gastrointestinal parasitic infections of Raeini goats

Raeini breed is the most productive Cashmere goat in Iran. Helminthes infections cause major economic losses globally to the livestock industries and farming communities. The objective of this study was to determine the seasonal prevalence and intensity of Eimeria and gastrointestinal helminth parasitic infections in Raeini goats in Iran. A total of 438 faecal samples were randomly taken from clinically healthy goats in Raeini Goats Research Center of Iran. Faecal samples were collected from each goat once and eggs per gram of faeces [EPG] and faecal oocysts counts [OPG] were estimated using the modified McMaster technique. Oocysts were found in 391 [89.27%] goats. Five species of Eimeria including, E. arloingi, E. parva, E. ninakohlyakimovae, E. christenseni, E. faorei and one Eimeria spp were identified in faecal samples. E. arloingi [92.07%] predominated in all categories and was followed by E. parva, E. ninakohlyakimovae and E. christenseni. Trichuris spp. egg was the only nematode egg which was found in 196 [44.75%] faecal samples. The prevalence of gastrointestinal helminthes infections during autumn and winter were significantly higher than summer [P<0.05]. The association between the prevalence of Eimeria oocysts and gastrointestinal nematode infection and the age or sex categories was not significant [P>0.05]

Prevalence of cryptosporidium spp. oocysts in diary calves in Kerman, Southeastern Iran

Faecal samples from 291 dairy calves from 10 dairy herds in Kerman were examined to investigate the prevalence of Cryptosporidium infection. Cryptosporidium spp. oocysts were identified by using the modified Ziehl-Neelsen staining technique in 63 [21.63%] calves. Calves were grouped according to their age as follows: <3 months, 3-6 months and 6-9 months. Cryptosporidium infection was detected in 28.2, 20.6 and 13.09%, of the calves in the respective age groups. A significant age-associated decrease in the detection rate of Cryptosporidium infection [P<0.05] was found. Cryptosporidium infection was detected in 11 of the 30 [36.66%] diarrhoeic and 52 of the 261 [19.92%] non-diarrhoeic calves. There was a significantly [P<0.05] higher prevalence of Cryptosporidium infection in diarrhoeic than in non-diarrhoeic calves

[ report on parasitic infections in camel [Camelus dromedarius] of Kerman slaughterhouse]

To determine the fauna and prevalence of parasitic infections of camel [Camelus dromedarius] in Kerman slaughterhouse. Sample Survey. Sixty slaughtered camel in Kerman slaughterhouse. Examination of different organs [including alimentary canal, abdominal cavity, liver, lung, kidneys, heart] and blood smear for parasitic infections were done. The parasites in the washed contents of alimentary canal, lung and sliced organ were cleared in lactophenol or stained with carmine acid collected, counted and identified under the microscope. Blood smears were stained with Gimsa-stain. Alimentary tract liver, lung, nasal cavity and blood were infected tissues. Eight species of parasites were detected in abomasum [Homoncus contortus; 6.67%], small intestine [Moniezia expansa, 5%; M. benedeni, 6.67%; Stilesia globipunctata, 8.3%], Liver [hydatid cyst, 3.3%], lung [hydatid cyst, 28%; Dictyocaulus filaria, 10%], nasal cavity [Cephalopina titillator larvae, 63.3%], blood: [Trypanosoma evansi, 1.6%]. For the first time we reported these parasites in camel from Kerman. According to average, minimum and maximum number of parasites recovered from infected animal no pathogenicity can be noticed for parasite burden of examined animals. However one camel with 43 larvae of Cephalopina titilattor in nasal cavity showed clinical signs, such as sneeze and snort
