Molecular evidence of Anaplasma phagocytophilumin aborted goat fetuses and placenta.

Anaplasma phagocytophilum, transmitted by Ixodes ticks, is an intracellular pathogen of zoonotic interest. Regarding animals of veterinary importance, infection by this agent has been linked mainly to high fever, neutropenia, reduced milk production, but hemorrhagic diathesis, abortion and impaired spermatogenesis have also sporadically been reported. In Greece, A.

Evaluation of the in-field efficacy of oregano essential oil administration on the control of neonatal diarrhea syndrome in calves.

The objective of this study was to evaluate under field conditions, whether daily administration of oregano essential oil is effective in preventing and/or diminishing the severity of neonatal diarrhea syndrome in calves aged less than 15days. Ninety-one newborn calves from three dairy farms were assigned into two groups; "Eco" group (n=46) calves were drenched with Greek oregano (Origanum vulgare ssp. Hirtum) essential oil (ECODIAR® liquid 5%) at the dose of 12.

Comparison of biuret and refractometry methods for the serum total proteins measurement in ruminants.

Background: Determination of serum total protein concentration is commonly performed by the biuret method. Refractometric measurement is a faster and less expensive alternative but its accuracy has not been determined in ruminants.

Objective: The purpose of the study was to compare the serum total protein concentrations in cattle, sheep, and goats measured by the biuret method with those obtained by refractometry.

In-field evaluation of clinoptilolite feeding efficacy on the reduction of milk aflatoxin M1 concentration in dairy cattle.

Background: Clinoptilolite is a natural zeolite with high adsorption capacity for polar mycotoxins such as aflatoxins. The efficacy of clinoptilolite in ameliorating the toxic effects of aflatoxicosis has been proven in monogastric animals, but there is no such evidence for ruminants. The aim of this study was to evaluate, under field conditions, whether the dietary administration of clinoptilolite in dairy cows could reduce the concentration of aflatoxin M1 (AFM1) in bulk-tank milk, in farms with higher than or close to 0.

Epidemiological Observations on Cryptosporidiosis in Diarrheic Goat Kids in Greece.

This study aimed at investigating the occurrence of Cryptosporidium spp. in diarrheic goat kids in Greece and the risk factors associated with cryptosporidiosis. Altogether, 292 diarrheic 4-15-day-old goat kids from 54 dairy goat herds of Northern Greece were examined.

Epidemiological characteristics and clinicopathological features of bluetongue in sheep and cattle, during the 2014 BTV serotype 4 incursion in Greece.

During 2014, an outbreak of Bluetongue virus (BTV) infections attributed to serotype 4 occurred in Greece and spread to south-eastern Europe. In the present article, the clinical and epidemiological data of 15 sheep flocks and 5 dairy cattle herds affected in Greece are described. In sheep, the most frequent clinical signs observed were fever, hyporexia, and edema of the face.

Serological investigation for West Nile virus, Anaplasma ovis and Leishmania infantum in Greek cattle.

This study investigates the seroprevalence of Greek adult cattle against West Nile virus, Anaplasma ovis and Lehismania infantum. In total, 156 serum samples were examined, drawn from cattle between 2-4 years old. All the examined cattle originated from slaughterhouses of 4 prefectures in Northern Greece (Thessaloniki, Pella, Chalkidiki, Kilkis), in 2 of which (Thessaloniki, Pella) human cases of West Nile virus had been recorded some months before.

Regurgitations in a Lamb with Acute Coenurosis-A case Report.

Coenurosis is a disease of the central nervous system in sheep, caused by Coenurus cerebralis, the larval stage of Multiceps multiceps, which inhabits the small intestine of Canidae. A case of regurgitations in a 2.5 month old lamb with acute coenurosis is being reported.

Reduction of the abortion rate due to Toxoplasma in 3 goat herds following administration of sulfadimidine.

The efficacy of sulfadimidine (4 doses of 33 mg/kg body weight, IM, q48h) against Toxoplasma abortion was assessed in 3 dairy goat herds suffering from Toxoplasma abortions during the 4th month of gestation. This protocol was very effective for the control of Toxoplasma abortions (P < 0.01).

Comparison of two techniques for diagnosis of cryptosporidiosis in diarrhoeic goat kids and lambs in Cyprus.

This study was conducted in the Larnaca area of Cyprus and included 28 goat and 15 sheep flocks suffering from neonatal diarrhoea (>20%). Faecal samples from diarrhoeic animals revealed that 25 of the 28 goat and 12 of the 15 sheep flocks were positive for Cryptosporidium. The ELISA was more accurate in the diagnosis of cryptosporidiosis compared to the Ziehl-Neelsen staining technique (P < 0.

Moxidectin efficacy in a goat herd with chronic and generalized sarcoptic mange.

A case of sarcoptic mange affecting almost all the animals of a dairy goat herd is described. This pruritic skin disease led progressively to high mortality and dramatic drop of milk yield. The lesions of the affected goats were typical of a chronic and generalized-diffuse sarcoptic mange.

Illthrift in suckling lambs secondary to umbilical infections and possible implication of cryptosporidiosis as a risk factor.

Illthrift was observed in 20/60 lambs aged 40-45 days in a dairy sheep flock in Greece. Cryptosporidiosis had been diagnosed and successfully treated with halofuginone lactate a month earlier. Parasitological examinations were negative for endoparasites while hematology and biochemistry were unremarkable.

Clinicopathological evaluation of downer dairy cows with fatty liver.

This study evaluated the relationship between severity of fatty liver and macromineral status in downer dairy cows and determined the usefulness of selected biochemical analytes for assessing prognosis. Blood and liver biopsy specimens were obtained from 36 Holstein downer cows shortly after the cows became recumbent and before they were treated. Liver tissue was examined histologically and serum activity of liver-derived enzymes and concentration of total lipids, triglycerides, bile acids, glucose, beta-hydroxybutyrate, acetoacetic acid, total bilirubin, non-esterified fatty acids (NEFA), cholesterol and macrominerals (Ca, Mg, K, Na, P) were determined.

Effects of in-feed inclusion of clinoptilolite on blood serum concentrations of aluminium and inorganic phosphorus and on ruminal pH and volatile fatty acid concentrations in dairy cows.

The experiment investigated the effects of the dietary inclusion of 200 g of the natural zeolite, clinoptilolite on the blood serum concentrations of aluminium (Al) and inorganic phosphorus (P) as well as on the ruminal pH and the ruminal concentrations of Al and P and of certain volatile fatty acids. Sixteen Holstein cows with a rumen fistula were randomly assigned to one of two groups. Group A cows (n = 8) were fed the basal ration supplemented with 200 g of clinoptilolite per day, and group B cows (n = 8) were fed the basal ration and served as controls.

Clinicopathologic evaluation of hepatic lipidosis in periparturient dairy cattle.

Background: Fatty change of the liver (FCL) is very common in dairy cattle periparturiently. Many laboratory methods have been implicated in order to assist the diagnosis.

Hypothesis: To investigate whether FCL in dairy cattle could be evaluated by assessment of ornithine carbamoyl transferase (OCT) by means of an assay modified for bovine serum, other enzyme activity, serum bile acids (SBA) concentration, or other biochemical constituents.

Evaluation of ornithine carbamoyl transferase and other serum and liver-derived analytes in diagnosis of fatty liver and postsurgical outcome of left-displaced abomasum in dairy cows.

Objective: To evaluate postsurgical outcome in dairy cows with left-displaced abomasum (LDA) with regard to severity of fatty liver and assess the usefulness of preoperative determination of serum ornithine carbamoyl transferase (OCT) activity, bile acids concentration, and other variables for evaluating liver function during the postsurgical convalescence period.

Design: Prospective study.

Animals: 68 Holstein cows.
