The animal health monitoring is required to issue health certificates. The viral hepatitis virus is one of the most important infectious agents in mice breeding colonies. This research used RT-PCR to identify contaminations to mouse hepatitis virus. 18 out of 29 specimens were found to be infected, a prevalence of 62%. PCR product was purified and sequenced. Phylogenetic analysis revealed that the identified strain in this study was closely related to a strain reported from France. In the conventional system, contamination with different infectious agents is inevitable, thus it is better to replace the contaminated colonies with clean animals.

Coenurosis (gid or sturdy) is a zoonotic disease that is caused by Taenia multiceps metacestode. It is common in small ruminants. The cysts in sheep are more cerebral, while are noncerebral in goats. Coenurosis decreases production, and results in the death of the affected animals and in the disposal of the organs or even carcasses in severe infection. The present study describes severe subcutaneous coenuri associated with contamination in other tissues including the skeletal muscles and visceral organs. A remarkable clinical observation was the aggregation of cysts in variable sizes in the subcutaneous tissue of whole body. Subcutaneous tissue is not a common site for cyst formation. Coenurosis was confirmed based on the morphological characteristics of the cysts including the clusters of protoscolices and rostellar hooks.

The study was carried out in Gimbi district, west Wollega zone, Ethiopia to assess beekeeping constraints and exploit the existing opportunities for beekeeping. The study used interview, survey and field observation as method of looking for answers for research questions. Purposive and simple random sampling techniques were used to select study sites and household respondents. 156 total household respondents were interviewed using semistructured questionnaires during the study period and SPSS software version 23 was used to analyze the gathered data. 5.42 ± 0.18, 10.23 ± 0.36 and 15.69 ± 0.59 kg were the average honey yield annually from traditional, intermediate and improved hive, respectively. Quality of honey (60.9%), distance from the market place (18.59%) and consumer’s preference (12.82%) were among the most factors governing the price of honey. Even though availability of bee forage and water, presence of immense number of bee density, high demand for local honey from honey traders and consumers and government attention to this sub-sector were encountered as opportunities for beekeeping development, improper application of agro-chemical inputs (1st), high cost of modern hive and equipment (2nd), diseases (3rd) and pests and predators (4th) were the challenges. Characterization of honeybees of the area, diseases and pest and predators needs further study.

The implantable drug products are developed mainly to sustain the drug release. This study was conducted to formulate and evaluate cross-linked films of chitosan/β-glycerophosphate (β-GP) for the sustained delivery of enrofloxacin (ENR). Two types of formulations, single-layer (F1 and F2) and triple-layer (F3 and F4) films, were prepared. In vitro drug release, kinetic modelling, Fourier transform infrared spectroscopy (FTIR) spectra, morphological and microbiological studies were performed. Drug release from F1 and F2 continued up to 5 hours but from F3 and F4, it was extended over 96 and 168 hours, respectively. The cumulative drug release for F1, F2, F3 and F4 were 72.6, 70.1, 90.5 and 82.4%, respectively. The inhibition zones of bacterial growth by using positive controls and single layer films were significantly greater than those of triple-layer films (p < 0.05), indicating sustained drug release pattern of the multi-layer films. These findings suggest that the triple-layer chitosan/β-GP films could be effective to deliver ENR for a long period.

Experiment was conducted to determine effect of Zataria multiflora boiss essential oil on stored spermatozoa. Semen collection was performed by using 15 mature roosters twice a week at four times. In each session, ejaculates were pooled and split into seven parts. The amounts of 0 (EO0), 50 (EO50), 100 (EO100), 200 (EO200), 400 (EO400), 600 (EO600) and 1000 (EO1000) ng/ml Zataria multiflora boiss essential oil were added to each part. Samples were chilled to 4°C and maintained for 72 h. Sperm assessment was performed at 0, 24, 48 and 72 h. Lipid peroxidation was evaluated after 48 h. Results showed that there was no interaction between Zataria multiflora essential oil and incubation time on membrane integrity, sperm motility and viability (p > 0.05). The highest sperm progressive motility (80.43%), viability (86.31%) and functional membrane integrity (85.81%) was observed in EO200 (p < 0.05). The lowest sperm motility (61.31%) and viability (73.31%) was observed in EO1000 (p < 0.05). The concentrations of malondialdehyde was lowest in EO200 (0.17 nM/ml, p < 0.05). Therefore, addition of 200 ng/ml Zataria multiflora boiss essential oil to semen improved longevity of rooster spermatozoa at 4°C.

The aim of this study was to investigate the in vitro acaricidal effect of aqueous ozone against Dermanyssus gallinae (Acari: Dermanyssidae) under laboratory conditions. For this purpose, aqueous ozone at concentrations of 1, 2, 3, 4, 5 and 10 ppm were prepared, and five replicate experiments were carried out using 400 µl of each concentration sprayed on every treatment batch of mites (plus a distilled water control). The mortality rate of mites in treatment and control groups were assessed 24 h post exposure. The mortality rate obtained by concentrations of 4, 5, and 10 ppm were significantly different from the control group (p < 0.05). The highest mortality rate (63.99%) was observed at concentration of 10 ppm. In this study, aqueous ozone showed a dose-dependent acaricidal potency against D. gallinae.

Neonatal isoerythrolysis is a major cause of anemia in newborn foals. However, there are no documented data regarding the occurrence of neonatal isoerythrolysis in Arabian horses of Iran, which are mostly raised in Khouzestan province. Hence, this study was carried out to investigate the occurrence of neonatal isoerythrolysis in Arabian horses of Khouzestan and assess the hematologic and serum biochemical profile of affected foals. A total of 20 neonatal foals, under one week of age, and their dams were involved in this study. Clinical examinations revealed no abnormality except in one foal with icteric mucous membranes, lethargy, tachycardia, tachypnea, hypothermia and hemoglobinuria which led to death. The diagnosis of neonatal isoerythrolysis was made based on erythrocyte agglutination in cross-match test between the mare serum and foal erythrocytes with the titer of 1:128, while other studied cases were assumed negative according to the test results. In the laboratory assessment, the foal with hemolytic anemia showed a major decline in hematocrit, hemoglobin concentration and erythrocyte count along with considerable leukocytosis and neutrophilia. Serum total and direct bilirubin concentrations in the NI case was about ten times higher than in the rest of the foals. This study revealed that neonatal isoerythrolysis can occur in Arabian foals of Khouzestan and is associated with severe anemia and icterus which may lead to death. These findings can be beneficial in the establishment of preventive measures in Arabian horse breeding industry in the region, as well as improving therapeutic methods.

Campylobacter is one of the main bacterial causes of ewe abortion throughout the world. Campylobacter infections are now considered as zoonoses. The objective of this study was an investigation of Campylobacter fetus prevalence among aborted ovine fetuses in the Sistan region (north of Sistan and Baluchestan province). In the present study, spleen and abomasum content samples were obtained from 78 aborted lambs of Baluchi sheep. The samples were examined for campylobacter contamination using PCR method. The overall prevalence of campylobacter infection was 7.7%. The prevalence of infection in fetuses aged three months and under were significantly higher than that in fetuses older than three months. The result of this study showed that C. fetus should be considered as one of the infectious causes of abortion among sheep flocks in Sistan region.

In this review an attempt has been made to review the cardiotoxic effects of poisonous plants which are found in Iran. Among various plant species growing in different regions of Iran, a large number of plants contain chemical compounds which are toxic to animals and humans. Among those poisonous plants, cardiotoxic plants are important due to the acute nature of their toxicity and frequent lethal livestock and human intoxications. Cardiotoxic plants of Apocynaceae family, Nerium oleander, N. indicum and Thevetia peruviana contain cardiac glycosides including oleandrin, oleandroside and thevetin A-C. Plants of Taxaceae family, Taxus baccata and T. brevifolia contain taxine alkaloids, including taxine A and B. The toxic effects of cardiac glycosides are primarily attributed to inhibition of plasmalemmal Na+/ K+-ATPase which results into the accumulation of intracellular Ca2+ and, depending to its severity, inotropic or arrhythmic effects are seen. Taxine B, the prominent alkaloid in Taxus spp. block sodium and calcium channels preferentially in cardiac myocytes, thus causing conduction abnormalities. Various cardiac arrhythmias in acute cases of poisoning with aforementioned plants result in acute heart failure and death. Post mortem findings are non-diagnostic and toxicological analysis of gastrointestinal tract content or body fluids is used for detection of cardiac glycosides and taxines.

Aslani","doi":"10.22067/VETERINARY.V10I1.72262","DOIUrl":"https://doi.org/10.22067/VETERINARY.V10I1.72262","url":null,"abstract":"In this review an attempt has been made to review the cardiotoxic effects of poisonous plants which are found in Iran. Among various plant species growing in different regions of Iran, a large number of plants contain chemical compounds which are toxic to animals and humans. Among those poisonous plants, cardiotoxic plants are important due to the acute nature of their toxicity and frequent lethal livestock and human intoxications. Cardiotoxic plants of Apocynaceae family, Nerium oleander, N. indicum and Thevetia peruviana contain cardiac glycosides including oleandrin, oleandroside and thevetin A-C. Plants of Taxaceae family, Taxus baccata and T. brevifolia contain taxine alkaloids, including taxine A and B. The toxic effects of cardiac glycosides are primarily attributed to inhibition of plasmalemmal Na+/ K+-ATPase which results into the accumulation of intracellular Ca2+ and, depending to its severity, inotropic or arrhythmic effects are seen. Taxine B, the prominent alkaloid in Taxus spp. block sodium and calcium channels preferentially in cardiac myocytes, thus causing conduction abnormalities. Various cardiac arrhythmias in acute cases of poisoning with aforementioned plants result in acute heart failure and death. Post mortem findings are non-diagnostic and toxicological analysis of gastrointestinal tract content or body fluids is used for detection of cardiac glycosides and taxines.","PeriodicalId":36826,"journal":{"name":"Iranian Journal of Veterinary Science and Technology","volume":"10 1","pages":"1-12"},"PeriodicalIF":0.0,"publicationDate":"2018-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42949259","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
