Statistical and spatial analyses of head lice infestation incidence showed a significant positive correlation with head lice infestation incidence hotspots and the altitudes (15-500 m), annual temperature range (14-16.5°C), and slope and average diurnal temperature (12-18°C). Conclusion The results of this study showed that the most ecologically suitable areas of head lice occurrence were identified in two hotspots (Parsabad and Germi) in the Northern areas of Ardabil Province (Parsabad and Germi counties); in the borderline of Iran and the Republic of Azerbaijan. Copyright © Adham, et al.Background and Aim Newcastle disease virus (NDV) remains a major viral disease of poultry. The morbidity and mortality rates of chickens vaccinated with NDV in broiler farms in Diyala Province were 100% and 80%, respectively, rates due to suspected infection with the highly virulent NDV. The present study aimed to isolate and identify the NDV virus and evaluate its pathogenicity in infected broiler chickens at poultry farms. Materials and Methods Broiler chickens at two commercial poultry farms were suspected of being infected with virulent NDV due to high mortality rates. Virus isolated from samples of intestinal tissues, lungs, trachea, spleen, kidneys, and air sacs was adapted in the allantoic cavity of embryonated specific-pathogen-free (SPF) chicken eggs. The NDV pathotype was determined based on the mean death time (MDT) in eggs as well as the intracerebral pathogenicity index (ICPI) and intravenous pathogenicity index pathogenicity indexes of the isolated samples. Broilers were experimentally infected nd RT-PCR. The isolated NDV caused 100% morbidity and 90% mortality in NDV-vaccinated and experimentally infected broiler chickens. Copyright © Alazawy and Ajeeli, et al.Aim A longitudinal study was conducted to assess the epidemiology of common gastrointestinal parasite (GIP) infections affecting goats in South Africa as influenced by agro-ecological zone (AEZ), sampling season, and the age and sex of animals.  https://www.selleckchem.com/products/ml385.html  Materials and Methods A total of 288 goats (101 male and 187 female) were randomly sampled during winter and summer in areas representing four AEZs (arid 80; semi-arid 76; humid 62; and dry sub-humid 70) of South Africa. Fecal samples from each animal were collected from the rectum, and the presence of GIP eggs was determined using a modified McMaster technique. A sample was considered positive when a minimum of one GIP egg was detected under the microscope. Fecal cultures were prepared, and infective larvae were collected and identified. The data were analyzed by MiniTab17 (2017) using the FREQ procedure, and the association between the independent factors and the prevalence of various GIPs were evaluated using the Pearson Chi-square test (p0.05) association between the other GIPs and sampling season. The prevalence of Eimeria spp. infection was higher in winter (34.0%) than in summer (26.0%). Conclusion AEZs and goat age are the most important risk factors influencing GIP infections in South African communal goats. These epidemiological parameters are important for outlining effective parasite control management systems against these GIPs in goats. Copyright © Mpofu, et al.Background and Aim Goat is considered very important ruminant animals that are raised in Jordan; however, the production of the local breeds is low to moderate, and thus, some genetic improvement programs could have a positive effect on the performance of the local breeds. The objective of this study was to investigate the effect of crossing Baladi (BB) goat with Shami. Materials and Methods A total of 30 newly weaned goat kids (15 BB and 15Shami-Baladi [SB] kids) were evaluated for growth performance and carcass traits. The trial lasted for 77 days (7 days for adaptation and 70 days for data collection). Feed intake was measured on a daily basis; body weight of kids was measured at the beginning of the study and biweekly thereafter. At the end of the trial, kids were slaughtered to examine carcass traits. Results Dry matter intake, initial weight, final weight, and average daily gain (ADG) were not affected by kid's breed type. In addition, breed type of kids showed no significant effect on feed efficiency (feedgain). Hot and cold carcass weight and dressing percentage were also not affected by kid's breed type. Kid breed type had no significant effect on shoulder, rack, and legs percentages. However, SB kids had a higher loin cut percentage compared to BB kids. In addition, Musculus longissimus depth was higher for SB kids. Conclusion Results of this study indicate that crossing SB goat breeds did not have a significant effect on either growth performance or carcass traits. Further studies using reciprocal cross may reveal different results. Copyright © Obeidat, et al.Background and Aim Ciguatera fish poisoning (CFP) is the most common form of seafood toxicosis reported in humans worldwide. Dogs and cats are also susceptible to CFP, but there is little published and much unknown about the condition in these species. This study aimed to document the demographics of canine and feline cases of CFP, to examine the temporal and spatial distribution of cases, and to compare the incidence of animal and human CFP in the Cook Islands. Materials and Methods Six years of medical records from the Esther Honey Foundation Animal Clinic (the only veterinary clinic in the Cook Islands during the study period) were reviewed to identify cases of CFP. The study variables included the date of presentation, species, age, sex, neutering status, and village/locality. Results A total of 246 cases of CFP were identified, comprising 165 dogs and 81 cats. The sexes were equally represented; however, within each sex, entire animals outnumbered those that had been desexed. Cases occurred year-round, with slightly higher numbers recorded in spring. Annual case numbers trended downward over the study period. Cases were documented in all regions of Rarotonga and also one outer island (Aitutaki). Fewer cases were seen in areas with a narrow (400 m) lagoon. Conclusion This study documented epidemiologic patterns of canine and feline CFP cases for the first time. Based on the results, further investigation is warranted to establish whether desexing has a protective effect against CFP. Copyright © Gray.
