Heads of sheep (n=180) and goats (n=120) slaughtered at four regions (Labraq, Shahat, Elbeida, and Masa) of Green Mountain areas in Libya were investigated for the presence of larvae of Oestrus ovis. The animals were divided into sex and age groups. The heads were cut along longitudinal and sagittal axes, and the larvae (L1, L2, and L3) were collected. The infestation rate was significantly higher in sheep (51.66%; n=93/180) as compared to goats (28.33%; n=34/120). In sheep, the rate was higher during May (100%), while in goat, it was higher during August (70%). The incidence of L1 peaked in April (90%) for sheep and October (100%) for goats, while L2 reached to maximum in May for sheep (26.95%) and goats (75%). L3 reached to peak in February (50%) for sheep, and June (25%) for goats. Mean intensity of larval burden was higher in sheep than goat, reaching to peak in June (9.1 larvae/head) for sheep and March (3.5 larvae/head) for goats. The infestation rate was significantly higher in males than females. The older animals were mostly affected as compared to younger animals. Highest infestation rate was recorded in Masa (45.83%), and the lowest rate was found in Labraq (40.27%). In conclusion, these findings may be used in designing the control strategies of myiasis in Libya.

A study was conducted to evaluate the effects of feeding processed kidney bean meal (PKBM) by replacing soybean meal (SBM) on fertility, hatchability, embryonic mortality and chick quality of white leghorn (WL) hens. A total of 225 white leghorn hens (195 layers and 30 cocks) with uniform body weight (BW) and age were randomly distributed into 15 pens and assigned to five treatments (i.e., T1, T2, T3, T4, and T5). A total of 360 eggs collected from all the treatment birds were used for the analysis. The feeds of the treatments were SBM substituted by PKBM at 0, 25, 50, 75 and 100% levels for T1, T2, T3, T4, and T5, respectively. Replacement of SBM with PKBM in the diet did not affect the fertility, hatchability, embryonic mortality, chick length, chick weight, and chick quality by visual score. As no difference is observed, 100% replacement of SBM by PKBM (dosed at 100 g/kg concentrate diet) is possible.

A case of gangrenous mastitis was surgically managed in a cross breed doe aging 3.5 years and weighing 25 kg at SA Quadery Teaching Veterinary Hospital of Chittagong Veterinary and Animal Sciences University, Chittagong, Bangladesh. Confirmatory diagnosis of the case was done based on physical changes of udder, and identification of associated bacterial agents; two bacteria namely Staphylococcus aureus and Escherichia coli could be isolated from the milk sample. Parenteral administration of combined antimicrobials (Gentamycin + Sulphadimidine + Trimethoprim) and concurrent intra-mammary infusion of antimicrobials (Streptomycin + Penicillin) along with supportive treatments for 7 days could not save the quarter rather the condition deteriorated. After performing the antibiogram of the isolated bacteria, only Ciprofloxacin was found to be sensitive. Mastectomy was done, and together with supportive medicine, Ciprofloxacin (dosed at 10 mg/kg body weight) was given intramuscularly as antimicrobial. The doe recovered without any complication after 7 days of post-treatment and management.

The study was conducted to know the effects of several genetic and non-genetic factors like season, sex, year of birth, genotype of calves and milk yield of dam associated with growth performance of crossbred calves. Data were collected from registered farmers during the period of May, 2011 to April, 2013. Birth weight, three-month weight, six-month weight, weaning weight and heritability estimates of those growth performances were performed using a total of 82 registered calves which had pedigree information having the genotypes of 25% Local - 75% Friesian and 37.5% Local - 62.5% Friesian. The average birth, three-month, six-month and weaning weight of calves were 29.33, 64.32, 99.06 and 151.77 kg, respectively. The effects of non-genetic factors like sex, season of birth and genotype were non-significant (P>0.05) for the traits birth weight, three-month, six-month, weaning weight and average daily gain of calves. However, year of birth was found significant on birth (P<0.01), three-month and six-month (P<0.05) weight; but non-significant (P>0.05) on weaning weight and average daily gain of calves. The heritability estimates were 0.40±0.09, 0.46±0.08, 0.39±0.12 and 0.50±0.12 for the traits birth weight, three-month weight, six-month weight and weaning weight, respectively. Estimated heritabilities of live weights suggest that individual own performance basis selection would be more effective for increasing growth and therefore, should be paid more emphasis in cattle improvement program.

ESAT-6 is one of the most studied antigens in vaccine, diagnosis, and pathogenic mechanism of tuberculosis. In the present study, a meta-analysis was performed regarding the use of ESAT-6 based antibody detection test for diagnosing nonhuman primate (NHP) tuberculosis. Studies in English and Chinese were searched and selected strictly. Quality of included studies was assessed using the standardized QUADAS-2 tool. Heterogeneity was explored through meta-regression. Finally, eight studies were included with high degree of homogeneity. Quality of included studies was general satisfied except the bias of “patient selection” for the majority of serum samples were from experimental infections. Estimates of sensitivity ranged from 69% to 82%, while specificity ranged from 96% to 99%. Area under ROC curves and Q were 0.9503 and 0.8909 respectively, indicating a high diagnostic accuracy. Current evidence suggests that ESAT-6 based serodiagnosis has the potential to become useful diagnostic tools for NHP tuberculosis.

Sheep play an important role in national economy and social economy in rural areas in Iran. The main goal of this study was to investigate the fauna and frequency of parasitic helminth infections prevalent in native sheep in Hamedan, western Iran. From April 2010 to March 2011, the gastrointestinal and respiratory tracts of 100-sheep were examined using conventional parasitological methods. The overall infection rate was found as 69%. No infection was found in esophagus and rumens. Parabronema skerjabini (22%) and Ostertagia circumcincta (1%) were recorded as the maximum and minimum cases for the presence of nematode, respectively. On the other hand, the most dominant of trematode and cestode were Fasciola hepatica (13%) and Monezia expansa (13%), respectively. The highest infection rate was reported in summer (84%). The prevalence of helminth infection was varied among gender, seasons and age groups. In conclusion, this is the first report of parasitic helminth infections in sheep in Hamedan province in western Iran. Our results provide baseline information for the future studies.

The process of programmed cell death, or apoptosis, is generally characterized by distinct morphological characteristics and energy - dependent biochemical mechanisms. Apoptosis is a widely conserved phenomenon helping many processes, including normal cell turnover, proper development and functioning of the immune system, hormone dependent atrophy etc. Inappropriate apoptosis (either low level or high level) leads to many developmental abnormalities like, neurodegenerative diseases, ischemic damage, autoimmune disorders and many types of cancer. To use cells for therapeutic purposes through generating cell lines, it is critical to study the cell cycle machinery and signalling pathways that controls cell death and apoptosis. Apoptotic pathways provide a fundamental protective mechanism that decreases cellular sensitivity to damaging events and allow proper developmental process in multi-cellular organisms. Major mediator of apoptosis is a family of proteins known as caspases. There are mainly fourteen types of caspases but out of them only ten caspasese have got essential role in controlling the process of apoptosis. These ten caspases have been categorized into either initiator caspases (caspase 2, 8, 9, 10) or executioner caspases (caspase 3, 6, 7). Although various types of caspases have been identified so far, the exact mechanisms of action of these groups of proteins is still to be fully understood. The aim of this review is to provide a detail overview of role of different caspases in regulating the process of apoptosis.

Sheep pox and goat pox (SGP) of small ruminants are most severing pox diseases of domestic animals, and they have a very important role in agricultural economy. Thereby, SGP are included in the notifiable diseases of Office International des Epizooties (OIE). Time and place distributions of these diseases are relatively stable worldwide. Transportation of infected animals could spread these viruses to the new areas. In most countries in which capripox are enzootic, vaccination and bio-security are the only two main control measures. SGP control programs have been commenced about 50 years ago in Iran, and there is a good situation for eradication of it. In this review, readers can find latest information in some essential aspects of etiology, distribution, transmission, and control of the diseases. Besides, current situation of the disease in Iran has been described, which perhaps are similar to the other endemic areas in the world.

Japanese Encephalitis (JE), a vector-borne zoonotic viral disease, is mostly prevalent in Asian countries. The objective of this study was to investigate the occurence of JE virus (JEV) among pigs in East Sumba, Indonesia. Blood samples (n=52) were randomly collected from 52 apparantly healthy pigs where pig population was high in East Sumba. The samples were subjected for seroprevalence study for the presence of antibodies against JEV using competitive enzyme linked immunosorbent assay (C-ELISA). Results showed that 53% (n=28/52) blood samples from the pigs contained antibodies against JEV. This finding is suggestive that the JEV is circulating among pig population in East Sumba, Indonesia. The data may help in designing control strategies of the JEV in the East Sumba, Indonesia.

The objectives of this study were to investigate the prevalence of gastrointestinal parasitism (GP), and to determine the effects of age, sex, breed, body score and body weight in the occurrences of GP of cattle in Banskhali Upazilla, Chittagong, Bangladesh. A total of 50 fecal samples were randomly collected directly from rectum of cattle. The samples were examined by routine coproscopical methods for the presence of different parasites and oocysts. Overall prevalence of GP infestation was 72% (n=36/50). Prevalence of Paramphistomum spp. infestation was found to be the highest (30%; n=15/50) followed by Toxocara spp. (12%; n=6/50), Fasciola spp. (10%; n=5/50), Oesophagostomum spp. (8%; n=4/50), Moniezia spp. (6%; n=3/50) and Trichostrongylus spp. (2%; n=1/50). Young cattle were mostly infested as compared to adult and calf. The results of this study provides an epidemiological forecast showing the prevalence of GP in cattle, which can be helpful for the clinician in diagnosis of such infections.
