“…The seropositivity of N. caninum in this study is higher in Holstein Friesian cross breed than Jersey cross breed and is non-significant. Sadrebazzaz et al (2004) also observed non-significant relation between the breeds of cattle to the N. caninum. The percentage of seropositivity of N. caninum is higher in cattle with infertility problems than the cattle with normal fertility and observed non-significant relation to the N. caninum.…”

“…Razmi et al (2006) reported the highest risk of abortion due to neosporosis in dairy cattle of 1-2 years of age. In contrast, Hajikolaei et al (2008) and Sadrebazzaz et al (2004), observed no significant difference between age and seropositivity to neosporosis. The presence of farm dog increases the seropositivity of N. caninum in the dairy cattle although it is non-significant but shows higher risk of N. caninum to dairy cattle.…”

Dairy industry is growing in Nepal and western dairy pocket area is the main milk producing area in Chitwan district. This study was carried out to determine the seroprevalence and risk factors associated with N. caninum in western dairy pocket area in Chitwan district of Nepal. A cross-sectional study was conducted from April 2014 to July 2014 among the small holder dairy farms, and out of 2188 animals from different sampling villages, 186 (8.5%) animals were randomly selected. Individual blood samples (5-10 ml) were collected and screened for N. caninum antibodies by ELISA test kit. The study showed that apparent overall prevalence of N. caninum to be 4.84% and true prevalence, 4.07%. The prevalence varied from a low of 0% to a high of 13.16% in various VDCs. The prevalence rates among Holstein-Friesian cross and Jersey cross Cattle were 6.94% and 3.51% respectively. The seroprevalence of N. caninum was found to be 16.13% and 2.5% in animals with and without history of abortion respectively, showed statistically significant different (p value <0.05). Similarly, prevalence were 13.64% and 3.66% in animals with and without presence of dog respectively and 8.5%, 3.39% and 0% in the animals of age group of 3-5 years, 1-3 years and above 5 years respectively, showed statistically non-significant association (p value <0.05). This study shows that N. caninum is associated with abortion in dairy cattle of Chitwan region. The study may contribute the base line data of N. caninum in Nepal for future preventive strategy for stake-holders and government.

“…The IFAT is a well-established test for detecting anti-N. caninum antibodies in dogs (Dubey et al, 1988a;1988b). In Iran, the presence of antibodies against N. caninum in dairy cattle (Sadrebazzaz et al, 2004;Razmi et al, 2006), camels (Sadrebazzaz et al, 2006) and farm and household dogs Malmasi et al, 2007) were reported. Based on the present study, this is the first report on the seroprevalence of in stray dogs of the Tabriz northwest of Iran.…”

“…N. caninum infection was first reported by in household dogs and dogs living in dairy and beef cattle farms. The presence of antibodies against N. caninum in aborted and healthy dairy cattle was detected and neosporosis importance in cases of cattle abortion is being increasingly demonstrated in Iran (Razmi et al, 2006;Sadrebazzaz et al, 2004;Habibi et al, 2005;Bonfitto et al, 2009;Saravanamurthy et al, 2010;Solhjoo et al, 2010). Nevertheless, no information on the prevalence of N. caninum infection in stray dogs is available in Iran.…”

Problem statement: To investigate anti-Neospora caninum antibodies in stray dogs living in Tabriz city, 100 blood samples were collected. Serum samples were screened for detection of anti-N. caninum IgG antibodies using Indirect Fluorescent Antibody Test (IFAT; ≥50). Antibodies were seen in 31 (31%) of 100 dogs. Approach: The IFAT antibody titers were as follows: 1:50 in 11 dogs, 1:100 in ten dogs, 1:200 in six dogs, 1:400 in one dog, 1:800 in two dogs and 1:1,600 in one dog. There were no significant differences in seroprevalence of Neospora infection between different genders (p>0.05). The seropositive results were increased with age and differences were statistically significant (p<0.05). Results:The results confirm the presence and exposure of stray dogs to N. caninum in Tabriz city and importance of this protozoan as a cause of disease in dogs of the region. Conclusion: Based on the present study, this is the first report on seroprevalence of N. caninum in stray dogs of the Tabriz northwest of Iran. This finding confirms the presence of Neospora infection and the important role of dogs in the region.

“…Neospora caninum infection in mainly diagnosed in living animals by means of serological tests, such as the indirect fluorescent antibody (IFA) test, the agglutination test and enzyme-linked immunosorbent assays (ELISA). Serological test for N. caninum are needed to obtain information about the epidemiology of the life cycle, to differentiate between a recent and chronic infection and determine seroprevalence in herds, regions and countries (BJORKMAN and UGGLA, 1999;SADREBAZZAZ et al, 2004). Repeat breeding is one of the major infertility problems affecting reproductive efficiency and economy of milk production in dairy animals.…”

Sera samples from 89 dairy cows with repeat breeder and 94 healthy pregnant dairy cows (controls) from Elazig province of eastern Turkey were tested for presence of Neospora caninum antibodies by use of a competitive enzyme linked immunosorbent assay (cELISA). Fifteen out of 183 cows tested (8.19%) were found to be seropositive to N. caninum antibody. Overall, seroprevalence of N. caninum was significantly higher (P<0.05) in dairy cows with repeat breeder (13.48%, 12/89) than in dairy cows with healthy pregnant (3.19%, 3/94). There was no statistically significant relationship between seroprevalence and breed and age groups in cows with repeat breeder (P>0.05). In conclusion, the current study highlights the importance of N. caninum in cows with repeat breeder.Key words: Neospora caninum, infertility, repeat breeder, seroprevalence. ZusammenfassungTitel der Arbeit: Seroprävalenz des Neospora caninum bei mehrfach kalbenden Kühen in der Türkei. (Kurzmitteilung) Von Milchkühen dreier Rassen und einer Kreuzungspopulation aus der Elazig Provinz in der Osttürkei wurden Blutserumproben bei 89 bereits mehrfach kalbenden und 94 gesunden tragenden Kontrolltieren auf Antikörperresistenz gegen Neospora. caninum mittels ELISA getestet. Bei fünfzehn = 8,19 % der 183 untersuchten Tiere wurden Antikörper nachgewiesen (P< 0,05). Mit 13,48 % (12 von 89 Tieren) war der Anteil mehrfach kalbenden Kühen signifikant höher als bei der Kontrollgruppe mit 3,19 % (3/94). Keine signifikanten Beziehungen (P> 0,05) ergaben sich zwischen der Serumprävalenz, der Rasse oder dem Alter der Tiere. Schlussfolgernd wird auf die Bedeutung von N. caninum bei mehrfach gebärenden Kühen hingewiesen.Schlüsselwörter: Neospora caninum, Unfruchtbarkeit, mehrfach kalbende Kuh, Serumprävalenz Introduction Neospora caninum is an apicomplexan protozoon parasite and is an important cause of abortion and infertility in cattle (DUBEY and LINDSAY, 1996). It was detected for the first time in dogs in 1984 (BJERKAS et al., 1984) and was described as a new genus Neospora, type species N. caninum, in 1988caninum, in (DUBEY et al., 1988. The dog was recently shown to be a definitive host for N. caninum (McALLISTER et al., 1998). There are several routes by which cattle may acquire Neospora infection, either by horizontal postnatal infection or by vertical transmission of the infection transplacentally during pregnancy (ANDERSON et al., 2000). Cattle with serological evidence of infection have an increased risk of abortion (THURMAND and HIETALA, 1997). Abortion can occur at any stage of pregnancy and cow that aborted a previous pregnancy due to neosporosis can abort again, or give birth SIMSEK et al.: Seroprevalence of Neospora caninum in repeat breeder dairy cows in Turkey 144 to diseased calves, calves with a subclinical N. caninum infection, or calves that are not infected (ANDERSON et al., 1995). Neospora caninum infection in mainly diagnosed in living animals by means of serological tests, such as the indirect fluorescent antibody (IFA) test, the agglutina...
