Evaluation Of Ultrasonography As A Diagnostic Tool For Hepatic Hydatid Cysts In Sheep, Hussein Awad Hussein, Mohammed Elrashidy

Turkish Journal of Veterinary & Animal Sciences

This retrospective study was designed to evaluate the use of ultrasonography for the diagnosis of hepatic hydatid cysts. This study was conducted on 22 sheep, which were classified into 2 groups according to their liver health group (healthy liver = 13 and cystic liver = 9). Biochemically, serum concentrations of gamma-glutamyl transferase, aspartate aminotransferase, total bilirubin, and globulins were significantly increased (P < 0.01) while albumin was lowered (P < 0.01) in sheep with cystic livers. Ultrasonographically, rounded, anechoic, and unilocular hydatid cysts with elliptical circumferences ranging from 6 to 10 cm were seen. The interiors of cysts contained echogenic particulate materials, septations, or fine echoes. At the 10th intercostal space (ICS), ventral margin, size, thickness, and angle of livers increased in sheep with hepatic cysts, while the diameter of portal vein decreased in sheep with liver cysts. At the 9th ICS, the circumference of the gall bladder was lowered in sheep with hepatic cysts (P < 0.01). The sensitivity, specificity, and positive and negative predictive values of ultrasonography for diagnosis of hepatic hydatid cysts were 80%, 100%, and 100% and 83%, respectively. In conclusion, ultrasonography alone or in combination with some biochemical parameters reflecting liver function could be helpful for the diagnosis of hepatic hydatid cysts in sheep.

Determination Of Plasma Fibrinogen And Haptoglobin, Hematological And Blood Biochemical Changes In Bulgarian Local Goats With Experimentally Induced Staphylococcus Aureus Mastitis, Ivan Fasulkov, Manol Karadaev, Nasko Vasilev, Valentina Urumova, Teodora Mircheva

Turkish Journal of Veterinary & Animal Sciences

The aim of the present study was to assess changes in acute phase proteins fibrinogen and haptoglobin, as well as hematological, blood biochemical, and microbiological alterations in local Bulgarian goats with experimentally induced Staphylococcus aureus mastitis. The experiments were conducted with 6 clinically healthy local Bulgarian goats, 2 to 6 years of age, weighing 46-57 kg. The experimental infection was done with a stationary phase culture of a field Staphylococcus aureus strain isolated from a cow with clinical mastitis. Blood haptoglobin in goats was considerably higher (P < 0.05) as early as 8 h after the pathogen's inoculation. The most significant differences from baseline values occurred 24 and 48 h (P < 0.01) after infection. Plasma fibrinogen increased significantly (P < 0.05) 8 h after infection and reached the highest mean concentration (9.12 g/L) by 72 h. Leukocytosis was established as early as 4 h after the experimental infection when leukocyte counts were significantly higher than baseline (P < 0.001). The analysis of results indicates that in experimentally induced Staphylococcus aureus mastitis, significantly higher (P < 0.05) levels of the leukocyte, fibrinogen, and haptoglobin are established as early as 8 h after the infection.

Turkish Journal of Veterinary & Animal Sciences

In the present study, sensitive and mutant colonies of some ruminal bacterial species isolated from sheep, cattle, and buffalo were detected. We counted and considered \"mutant colonies\" the bacterial colonies grown in the clear inhibition zone in the Kirby-Bauer disk diffusion susceptibility test. Detected mutant colonies were higher in buffalo than in cattle and sheep. Duricef and metronidazole caused no mutations in any species. The others formed mutant colonies, where roxithromycin = polymyxin = chloramphenicol = gentamicin < erythromycin < vancomycin < piperacillin = cefotaxime < streptomycin < cefoperazone < ciprofloxacin < amikacin. Sheep had the highest number of sensitive isolates, and the number of sensitive isolates was dramatically lower in cattle and buffalo. There were no sensitive isolates with the antibiotic metronidazole, and there was a low number of sensitive isolates with duricef. The other antibiotics had more sensitive isolates (gentamicin = ciprofloxacin = amikacin > streptomycin = piperacillin > erythromycin > vancomycin = cefoperazone = cefotaxime > roxithromycin > polymyxin > chloramphenicol). The number of sensitive isolates of the different ruminant species for …

Recent Advances In The Immunology And Uterine Microbiology Of Healthy Cows And Cows That Develop Uterine Disease, Klibs N. Galvao, Jose Eduardo P. Santos Jan 2014

Recent Advances In The Immunology And Uterine Microbiology Of Healthy Cows And Cows That Develop Uterine Disease, Klibs N. Galvao, Jose Eduardo P. Santos

Turkish Journal of Veterinary & Animal Sciences

Uterine diseases are highly prevalent in dairy cows. Causes of uterine diseases are multifactorial. There is good evidence for the susceptibility of the host and for the role of pathogenic bacteria, and less evidence for the effect of the environment. Uterine and leukocyte immune response is impaired early postpartum in cows that develop uterine disease. The decrease in immune function is associated with a decrease in calcium postpartum and an increase in NEFA and BHBA. Both endometrial cells and granulosal cells possess toll-like receptors (TLR) that can recognize and mount an inflammatory response to pathogen-associated molecular patterns (PAMPs) such as …

New Understanding Of An Old Phenomenon: Uncontrolled Factors And Misconceptions That Cast A Shadow Over Studies Of The ‘Male Effect’ On Reproduction In Small Ruminants, Trina Jorre De St Jorre, Penny Alison Rhian Hawken, Graeme Bruce Martin Jan 2014

New Understanding Of An Old Phenomenon: Uncontrolled Factors And Misconceptions That Cast A Shadow Over Studies Of The ‘Male Effect’ On Reproduction In Small Ruminants, Trina Jorre De St Jorre, Penny Alison Rhian Hawken, Graeme Bruce Martin

Turkish Journal of Veterinary & Animal Sciences

In female sheep and goats, exposure to males can be used to induce ovulation and thus control and synchronise fertility. This 'male effect' offers simple, cost-effective, and hormone-free management of reproduction in flocks and herds but, despite decades of research, significant gaps in our knowledge impede commercial application. Many of these gaps can be traced back to misconceptions in the early documentation of the male effect, and others are the result of uncontrolled factors in experimental design. Consequently, it is often difficult to draw conclusions from past research, to further our understanding of the phenomenon, and to make recommendations for …
