First observations on the occurence of giardia bovis fantham, 1921 in cattle in Turkey

Türkiye 'de sığırlarda Giardia bovis'in bulunuşu ilk kez kaydedilmektedir. Mart 1982 de rutin bakılan yapılmak üzere Genel Parazitoloji ve Helmintoloji Laboratuvarına yollanan 15 sığır dışkısının 2'sinde (% 13.33) Giardia bovis kist ve trofozoit formlarına rastlanmıştır. Trofozoit formlarının 12-18.2 ym uzun, 7.2-9.6 ym geniş, kist formlarının 10.4-16 ym uzun 7.2-9.6 ym geniş olduğu ölçülmüştür. Her iki olayda hayvanların genç, diyareli, dışkılarının da mukuslu olduğu kaydedilmiştir. ilk hayvanda başka bir parazit görülmemesine karşın ikinci olayda fazla sayıda Eimeria oocyst'lerine de rastlanmıştır. Buzağılar "septicemia neonatorum" ve "coccidiosis" yönünden sağıtılmışlar, sağıtım sonrası yukarıda belirtilen klinik septomların kaybolduğu gözlenmiştir.The occurence of Giardia bovis in cattle recorded for the first time in Turkey. In March 1982, 2 out of 15 faeces of cattle ( 13.33 %) which were sent to the Parasitology Laboratory for routine examination were found harbouring the cyst and trophozoit forms of Giardia bovis. The trophozoit were 12 to 18. 2 ym long and 7. 2 to 9. 6 ym wide, the cysts were 10.4 to 16 ym long and 7.2 to 9.6 ym wide. In the both cases animals were young and suffernig from diarrhea. Large amount of mucus were present in their faeces. In the first case no other parasitic agent was seen, contrary to this, in the second case Eimeria oocysts were also detected. Calves were treated for "septicemia neonatorum" and "coccidiosis" respectively and elinical semptoms disappeared

Quantitative analysis of microfilarial periodicity of dirofilaria immitis in dogs

Dirofilaria immitis ile enfekte köpeklerde, perifer kandaki mikrofiler periodisitesi, trigonometrik metot kullanılarak 4 sayım yöntemine göre analiz edilmiş ve yöntemler arasındaki farklılıklar istatiksel olarak araştırılmıştır. Enfekte iki köpekten, yirmi dört saat süresince 2 saat aralıklarla kan alınmış,aynı zamanda köpeklerin vücut ısısı ile kalp frekansı ve solunum sayıları kaydedilmiştir. Bu işlemler 2 gün arayla tekrarlanmıştır. İstatistiksel olarak, gözlenen ve teorik olarak beklenen mikrofiler yoğunlukları arasındaki en iyi uyum membran filtrasyon testi ile yapılan sayım sonucu elde edilmiştir. Bu yönteme göre her iki köpek için saptanan periodisite indeksi 42.945.3, maksimum mikrofiler yoğunluğunun beklenen saati (K) 20.6-21.2 olarak bulunmuştur. Bu sonuçlarla D. immitis enfeksiyonunda mikrofiler periodisitesi geceye yönelik (nokturnal) subperiodik form olarak belirlenmiştir. Aynı zaman di-limlerinde kanda gözlenen mikrofiler yoğunluğu ile kalp frekansı arasında köpek no l 'de r0.17 (p0.05) pozitif yönlü ancak zayıf bir ilişki, köpek no 2'de r -0.62 (p0.05) negatif yönlü kuvvetli sayılabilecek bir ilişki saptanmıştır. Her iki köpekte mikrofiler yoğunluğu ile vücut ısısı, solunum sayıları arasında istatistiksel anlamda önemli bir ilişki saptanmamıştır (p0.05).Microfilarial periodicity of Dirofilaria immitis in the venous blood of infected dogs was analyzed according to four counting methods by using trigonometric model and, the differences among the counting techniques were examined statistically. The blood was collected from infected dogs every 2h during 24h period beginning at 6.00h, at the same time body temperature, pulsation and breathing frequency of dogs were recorded. Procedures explained above were repeated two times. Statistically, the highest correlation between the observed and expected microfilarial densities was determined by the membrane filtration technique. According to this technique, calculated periodicity index was 42.9-45.3 and the estimated hour of peak (K) microfilarial density was ranged from 20.6-21.2h in these two dogs. Thus the periodicity of microfilaria of D. immitis was characterized as nocturnally sub-periodic In the dog no 1, the correlation between the observed microfilarial densities and pulsation at the same time periods was r0.17 (p>0.05) and in the dog no 2 was r -0.62 (p0.05) among microfilarial densities, body temperature and breathing frequeny in both dog

The seroprevalence of BHV-1 infection on selected dairy cattle herds in Turkey

In this study, serum samples of 13011 cattle from 31 dairy herds located in various regions of Turkey were tested for presence of neutralising antibodies against BHVI using the serum neutralisation (SN) technique. It was found that 97% (30/31) of the herds selected had seropositive animals and the frequencies of seropositivity were between 0.5-79.5% in the surveyed herds. Furthermore, recommendations to the control and eradication programme of the BHV1 infection were presented

Prevalence, distribution, and host range of Peste des petits ruminants virus, Turkey

Peste des petits ruminants virus (PPRV, genus Morbillivirus), which causes a severe disease in sheep and goats, has only recently been officially declared to be present in Turkey. We carried out a study to determine the prevalence, distribution, and host range of PPRV in Turkey. A total of 1,607 animals, reared in 18 different locations, were monitored for the presence of antibodies to PPRV and the related virus of large ruminants, Rinderpest virus (RPV). Only two farms had animals that were free of antibody responses to either disease. Prevalence for PPRV infection varied (range 0.87%-82.6%) and was higher in sheep (29.2%) than in goats (20%). The overall antibody responses to PPRV and RPV were 22.4% and 6.28%, respectively. Two PPRVs of lineage 4, which comprises many other PPRVs whose origins are in the Middle East, the Arabian Peninsula, and southern Asia, were isolated from Turkish sheep
