ÖzetÇalışma, Mart 2008 ile Haziran 2009 tarihleri arasında, Kars yöresinde sığır ve köpeklerde N. caninum'un yaygınlığını belirlemek ve ithal sığırların girdiği ve hiç girmediği köy grupları arası karşılaştırma yaparak epidemiyolojik olarak risk faktörlerini ortaya koymak amacıyla yapıldı. Çalışma alanını temsil etmek üzere yurt dışından ithal sığırların girdiği 6 köy (Grup 1) ve girmediği 6 köy (Grup 2) toplam 12 köy rastgele örnekleme yöntemiyle belirlendi. N. caninum antikorlarını ortaya koymak için ticari kitler (sığırlar için CI-ELISA, köpekler için IFAT) kullanıldı. Köpek dışkı örneklerinin muayenesinde ise direkt natif dışkı ve Sheather'in şekerli su ile flotasyon teknikleri kullanıldı. Veriler Ki kare testi ile değerlendirildi. Kars ilinde CI-ELISA ile N. caninum'un serolojik yaygınlığı, her iki gruptan toplam 1100 sığırda %7.2, Grup 1 köylerden 500 sığırda %9.2 ve Grup 2 köylerden 600 sığırda %4.8 olarak bulundu. Köpeklerde IFAT ile aynı sırayla, 210 köpekte %25.2, 101 köpekte %30.7 ve 109 köpekte %20.2 olarak belirlendi. Hem sığırlarda hem de köpeklerde gruplar arasındaki yaygınlık oranları anlamlı (P<0.05) derecede farklı bulundu. Gerek sığırlarda gerekse köpeklerde serolojik yaygınlık oranları yaşlı hayvanlarda gençlere oranla daha yüksekti (P<0.05). Her iki grup köyden toplam 125 köpeğin dışkı yoklamasında 10 (%8.0) hayvanda N. caninum benzeri ookistler görüldü. Bu çalışmanın sonuçları, Kars'ta sığırlarda ve köpeklerde postnatal enfeksiyonların geliştiğini ve sığır neosporosisi için epidemiyolojik olarak köpeklerin potansiyel bir risk faktörü olduğunu göstermektedir. Ayrıca ithal sığırların girdiği köyler, sığır ve köpeklerde seroprevalans daha yüksek bulunarak, riskli grup olarak görüldü. SummaryThis study was performed in order to establish the prevalence of N. caninum in dogs and cattle in the province of Kars, between March, 2008 and June, 2009. To identify the risk factors epidemiologically, a cross sectional study was made between villages known to have imported cattle breeds and villages with only indigenous cattle. Twelve villages were randomly selected as representative of the study area; six of the villages had imported cattle breeds (Group 1), while the remaining six did not (Group 2). Commercial kits (competitive inhibition ELISA, CI-ELISA for cattle, IFAT for dogs) were used to identify antibodies to N. caninum. Faecal Direct Smear and Sheather's Sugar Flotation techniques were used for the examination of dog faecal samples. The data were evaluated by the chi square test. The CI-ELISA test revealed that the seroprevalence of N. caninum in Kars Province was 7.2% in a total of 1100 cattle from both groups of villages; 9.2% in 600 cattle from Group 1 villages and 4.8% in 500 cattle from Group 2 villages. The seroprevalence in dogs as determined by IFAT was 25.2% in a total of 210 dogs while it was 30.7% in 101 dogs from Group 1 villages, it was 20.2% in 109 dogs from Group 2. In both cattle and dogs, the differences in seroprevalence between in the Group 1 and 2 villages were found to be...

Neospora caninum is considered a major cause of abortion in cattle. Appropriate techniques for diagnosis of bovine neosporosis, both in vivo and in aborted foetuses, have been developed in the last ten years and some of them are commercially available. For diagnosis in live animals, detection of antibodies in serum or milk has been shown to be the best option both at the herd and the individual level. These techniques are excellent tools to examine N. caninum-associated abortion problems and to adopt some basic herd-control measures. Concerning foetal diagnosis, detection of compatible lesions by histological examination and parasites by PCR in brain (as well as heart and liver) are the best choices. Diagnostic criteria to distinguish foetal infection and Neospora-associated abortion are based not only on the demonstration of the parasite in the foetus but also on the extent and severity of the lesions in the foetus, foetal age and the assessment of neosporosis at the herd level. In the near future, new tools to diagnose infection should help to detect animals with parasite reactivation by testing the immune response to stage-specific antigens and lead to the development of molecular typing methods to characterise different parasite isolates. Finally, uniform diagnostic procedures need to be established between laboratories and countries in order to standardise result interpretation. The role of National or Regional Reference Laboratories is essential in countries or regions where control programmes for the disease are being developed.

“…Paratuberculosis is becoming a generalised infectious problem in cattle in developed countries (Maning and Collins, 2001), and a high neosporosis seroprevalence has been also observed in the European cattle population (Bartels et al, 2006). (iii) It is believed that beef sires are more fertile than dairy cattle, and beef cattle sperm is more frequently used in cows that do not become pregnant.…”

The use of crossbreeding with beef bulls in dairy herds: effects on calving difficulty and gestation length

This study was designed to analyse the evolution in the use of beef bull semen for dairy cattle insemination and, mainly, to assess calving difficulty, gestation length and proportion of stillbirths after breeding pure Holsteins or crossbreeding. Between the latter two, pure Holstein had the shortest gestation length. Calving difficulty and gestation length decreased as the age of the dam advanced. The most difficult calvings were observed in twin calvings, followed by the calvings of male calves and female calves. The gestations leading to the birth of male calves were longer than those leading to female calves and twin calves. Stillbirths were not related to the breed used for mating. Through examining these parameters, sire breed should be considered when selecting a beef breed for the insemination of milk-producing dams.
