Prevalence, Virulence And Antibiotic Susceptibility Of Listeria Monocytogenes Isolated From Sheep, Shaimaa Elbar, Rasha Elkenany, Mohamed Elhadidy, Gamal Younis
Mansoura Veterinary Medical Journal
Objective: This study was undertaken to determine the prevalence, virulence, and antibiotics susceptibility of Listeria monocytogenes isolated from hindbrain, spinal cord, milk, and intestinal content collected from sheep in the Dakahlia Governorate, Egypt.Design: Observational study.Samples: We analyzed 472 samples, including 72 hindbrain/spinal cord samples from emergency-slaughtered sheep, 300 raw-milk samples from apparently healthy sheep, and 100 intestinal content samples from slaughtered sheep at three abattoirs.Procedures: Isolation and identification of L. monocytogenes were performed using conventional techniques. The biochemically identified isolates were confirmed by 16SrRNA gene sequencing and examined for virulence-associated genes (hlyA and iap) as well as for antimicrobial susceptibility.Results: …

Livestock Preference For Endophyte-Infected Or Endophyte-Free Oxytropis Sericea, Ipomoea Carnea, And Ipomoea Asarifolia, James Pfister, Daniel Cook, Stephen T. Lee, Dale R. Gardner, Franklin Riet-Correa
Poisonous Plant Research (PPR)
Fungal endophyte-infected forages have been shown to alter herbivore feeding preferences. The objective of this experiment was to compare the preference of cattle, sheep, and goats for plants containing (E+) and not containing (E-) fungal endophytes using freshly harvested Oxytropis sericea, Ipomoea carnea, and Ipomoea asarifolia. Goats and sheep rejected all forage choices regardless of endophyte status except for grass and alfalfa hay. Endophyte status had no influence on cattle forage preferences. Cattle rejected all Oxytropis sericea E+ and E- choices. Cattle discriminated between Ipomoea species, preferring Ipomoea carnea to Ipomoea asarifolia (P = 0.004). In all …

Expression Pattern Of Heat Shock Protein Genes In Sheep, Fawzy Younis
Mansoura Veterinary Medical Journal
Objective: To recognize the expression patterns of HSP70 and HSP90 genes in two local breeds of Sheep. Design: Descriptive study. Animals: Fifty ewes (25 Barki and 25 Abu Dlik). Procedures: This investigation was carried out on fifty sheep at the northwest coast and southeast of triangle Halayeb and Shalateen during the months of March and May 2018 and 2019 (average day time temperatures: 25–35 ◦C; relative humidity: 55–65%). Total RNA was extracted using easy-RED™ Total RNA Extraction Kit. The primers for qPCR were designed on the basis of prior sequence information available at National Center for Biotechnology Information (NCBI) for …

Turkish Journal of Veterinary & Animal Sciences
The article investigates into the species composition of agents causing gastrointestinal tract nematodes in sheep. It determines the forms of nematodes communities. For this purpose, 710 sheep were examined, 79.58% of which were infected. The fauna of nematodes was represented by 15 species of helminths from 12 genera: Bunostomum, Oesophagostomum, Nematodirus, Chabertia, Cooperia, Trichostrongylus, Ostertagia, Haemonchus, Trichuris, Aonchotheca, Strongyloides, and Skrjabinema. The indicators of infestation intensity in sheep ranged from 1 to 93 specimens per animal, and the abundance index ranged from 0.01 to 16.96 specimens per animal. The most common nematodes are H. contortus (prevalence, 61.97%), O. circumcincta (59.58%), …

Amongst ruminant livestock diseases, the gastrointestinal (GIT) helminths and protozoan parasite infections result in a significant socio-economic concern worldwide. During the period between October 2017 and November 2018, a total of 788 fresh fecal specimens from cattle (n = 303) and sheep (n = 485) were screened for the presence of gastrointestinal helminths and protozoan parasites in two historical regions (Crisana and Banat) of western Romania. Laboratory processing of fecal samples with the simple salt flotation (Willis) and sedimentation techniques, followed by microscopic analysis revealed that 86.1% of cattle and 92.6% of sheep were found to be positive for at …
A Phylogenetic Analysis Of Mycoplasma Strains Circulating In Sheep Pneumonia In Thekars Region Of Turkey, Olcay Öztürkler, Sali̇h Otlu
A Phylogenetic Analysis Of Mycoplasma Strains Circulating In Sheep Pneumonia In Thekars Region Of Turkey, Olcay Öztürkler, Sali̇h Otlu
Turkish Journal of Veterinary & Animal Sciences
This study aimed to investigate Mycoplasma species by cultural and molecular methods in 250 pneumonics and 30 healthy appearance sheep lungs brought from slaughterhouse and butcheries in the Kars region of Turkey. The phylogenetic positioning of the bacterial strains to be obtained in the present study was another remarkable outcome of the study. Mycoplasma isolation was achieved solely in 26 (10.4%) of 250 sheep lungs with pneumonia. Mycoplasma ovipneumoniae was found predominant species in 12 (46.15%) of samples and that was followed by Mycoplasma arginini in 4 (15.38%) of strains. Moreover, two samples were found to be co-infected with the …
Embryonic Mortality In Sheep: A Review, Pavitra Chundekkad, Barbara Blaszczyk, Tomasz Stankiewicz
Embryonic Mortality In Sheep: A Review, Pavitra Chundekkad, Barbara Blaszczyk, Tomasz Stankiewicz
Turkish Journal of Veterinary & Animal Sciences
Despite extensive research on the reproductive health of domestic animals, embryonic mortality continues to be a problem that brings about significant losses for both commercial breeding and scientific research. This review paper discusses the genetic and environmental factors that affect embryo mortality rates in sheep along with the different techniques developed to overcome this issue. Additionally, one of the objectives of this study is to emphasize the importance of the use of time-lapse cinematography and color Doppler ultrasonography as quick and reliable methods for early detection of pregnancy and embryonic death.

Turkish Journal of Veterinary & Animal Sciences
Bacterial lipopolysaccharides (LPS) play a key role in the pathogenesis of subacute ruminal acidosis (SARA). Limited attempts have been made to inhibit LPS absorption during SARA. Therefore, this study aimed to evaluate the impacts of oral usage of activated charcoal and zeolite on serum LPS and acute phase proteins (APPs) levels in lambs with SARA. Fifteen lambs were randomly assigned to 3 groups, each containing 5 lambs: control, activated charcoal, and zeolite. In all groups, SARA was induced for 7 days through increasing the crushed corn ration to 52.8% and reducing the rumen pH to the range of 5.7-5.6. In …
