This study aimed to compare estrous performance and progesterone concentration during the estrous cycle of kacang goats induced by PGF2α versus ovsynch protocol. This research used six female kacang goats. The goats were divided into two groups namely the K1 group which was induced by injecting 7.5 mg PGF2α intramuscularly in 10 days interval and K2 group which was induced by using the ovsynch method. Protocol for K2 group was as follow; at day 1, the goats were injected with 7.5 mg PGF2α; at day 8, they were injected with 50 µg GnRH; at day 15 they were injected with 7.5 mg PGF2α; at day 18 they were injected with 50 µg GnRH. Estrous were detected using male goat and visual observation. The blood samples were taken on days 7, 14, and 21 after estrous. Progesterone concentration was measured with enzyme-linked immunosorbent assay (ELISA) technique. Intensity, onset, and duration of estrous in K1 group versus K2 group were 8.33±2.08 vs 7.00±1.00; 56.00±34.12 vs 36.00±20.78 hours; and 24.00±26.15 vs 24.00±20.78 hours, respectively (p>0.05). Level of progesterone hormone on day 7, 14, and 21 for K1 vs K2 were 0.812±0.710 vs 2.369±3.351; 5.051±7.754 vs 3.091±4.385 ng/ml; and 4.173±6.692 vs 3.562±4.113 ng/mL, respectively (p>0,05). It can be concluded that the differences in synchronization protocols between PGF2α versus ovsynch do not affect the performance of estrous and the concentration of progesterone during the estrous cycle of kacang goats.

This study aimed to investigate the correlation between progesterone hormone concentration and number of fetus as well as the difference in progesterone hormone concentration from different gestation periods in Etawah crossbred (EC). Five EC goats used in this study were injected with 2 mL of 5.5 mg prostaglandin F2α (PGF2α, Capriglandin) intramuscularly, with an interval of 10 days. Goats that showed symptoms of estrus were mated naturally with male goats. Blood samples were taken on the 7th, 14th, 21st, and 75th days of gestation. Progesterone hormone concentration was determined using enzyme linked immunosorbent assay (ELISA). The number of fetus was determined at 35th gestational day using ultrasonography (USG). Four out of 5 goats were found to have 1 fetus and 1 goat had 2 fetuses. The progesterone concentration on the 7th, 14th, 21st, and 75th days of gestation in goats with single fetus were 5.21, 7.78, 11.97, and 18.78 ng/mL, respectively, while in goat with two fetuses were 8.44, 14.53, 16.81, and 22.73 ng/mL, respectively. The correlation (r) between progesterone hormone concentration and number of fetus on the 7th, 14th, 21st, and 75th days of gestation were 0.442, 0.854, 0.592, and 0.757, respectively. It is concluded that progesterone concentrations are highly correlated to the number of fetus in each gestation period in EC goats.

This study aimed to compare the progesterone concentrations in Waringin sheep estrus cycle which induced by PGF2α or the combination of PGF2α and GnRH. This study used six Waringin sheep those were divided into twice groups, K1 and K2. K1(n=3) were injected by 7.5 mg PGF2α intramuscularly for 10 days, while K2 (n = 3) were injected by PGF2α and GnRH. On the first day K2 were injected by 7.5 mg PGF2α, then followed by injection 50 µg of GnRH on day 8th and re-injected by 7.5 mg PGF2α on day 15th. On day 18th, sample was re-injected using 50 µg GnRH. Waringin sheep those showed estrus symptoms were detected visually and with signs showed by sheep stud. Blood samples were taken on the 7th, 14th, and 21st day after the peak heat. The measurement of progesterone concentration was conducted by enzyme linked immunosorbent assay (ELISA). The results showed those the concentrations of progesterone on day 7th, 14th, and 21st on K1 vs K2 were 1.324±1.079, 7.607±8.922, and 5.220±1.653  vs 4.705±3.369, 4.184±5.512, and 1.797±0.898 ng/mL (P>0,05), respectively. In conclusion, the concentration of progesterone of Waringin sheep after inducing with PGF2α or combination PGF2α and GnRH at different cycle periode did not show differences. Keywords: Estrus Cycle, GnRH, PGF2α, Progesterone, Waringin Sheep

A survey of helminth parasites was carried out on 198 dogs living in almost complete liberty in villages in the northeast of Gabon. Faeces and blood samples were collected and analysed. Dirofilariaimmitis antigen was detected in 13.6 % of dogs using the SNAP 3Dx® test, a commercially available enzyme-linked immunosorbent assay (ELISA). Faecal examination revealed that 91.4 % of dogs were infected by intestinal helminths. Ascarids were found in 58.5 % of the samples. Trichuris vulpis was observed in 49.5 % of cases, and Uncinaria spp. and Ancylostoma spp. in 34.8 %, Spirocerca lupi in 25.3 % and Capillaria spp. in 10.6 %. Cestode embryophores were found in 8.6 % of the samples.

SUMMARYPassive immunity against measles decreases during the first months of life. The objective of this study was to determine titres of measles antibodies in children aged 9–14 months and their mothers before vaccination, and the children's response to vaccination. Blood samples were collected by capillary puncture before and 28 days after vaccination. Samples were obtained between February and June 2007 during an ongoing measles outbreak. Titres of specific measles IgG antibodies were determined by enzyme-linked immunosorbent assay. Seroconversion was defined as the presence of antibodies after vaccination in subjects without antibodies before vaccination. Maternal antibodies were present in 37·7% of all 69 children included and in 45·1% of children aged 9 months. Of the 51 children in whom a second sample was obtained, 31 (60·8%) were seronegative before vaccination and 61·3% seroconverted. Interference of maternal antibodies was 30%. Advancing the first dose of measles vaccination from 15 to 12 months is a correct strategy, given the increase in the time of susceptibility of infants to measles.

Prolactin has been reported to be a remarkable index of stress response, both acute and chronic, in several species. The use of biological matrixes other than blood is receiving increasing interest in the study of hormones, due to the lower invasiveness in collection. This research aimed to investigate the possibility of using a commercial ELISA (enzyme-linked immunosorbent assay) kit for measuring canine prolactin in blood for the quantification of canine prolactin in saliva. Study 1 consisted of a validation protocol, using saliva samples collected from lactating and non-lactating dogs. Study 2 was conducted to investigate a possible correlation between prolactin concentration in saliva and plasma in sheltered dogs by using the same kit. Prolactin values were reliably read only when they came from blood samples, not from saliva, but tended to be low in most of the cases. Study 1 showed that saliva had a matrix effect. In study 2, saliva prolactin levels were low and in 42.9% of cases, not readable. No correlation between prolactin values in plasma and saliva was found (ρ=0.482; p=0.274). These findings suggested that the determination of prolactin in dog saliva through an ELISA kit created for measuring prolactin in dog blood was unreliable.

AbstractThe present study was conducted to determine the prevalence of canine dirofilariosis in Hatay province, south of Turkey. A total of 269 blood samples were collected from owned dogs in this multi-centre survey between March and July 2006. Blood samples were examined by modified Knott and enzyme-linked immunosorbent assay (ELISA) techniques to detect circulating microfilariae and antigens of Dirofilaria immitis, respectively. Seventy out of 269 dogs (26.0%) were positive for D. immitis. However, 61.4% of positive dogs had occult infection. The prevalence of canine dirofilariosis was heterogeneous in Hatay province, with higher values in shoreline (33.0%) and riverside (30.9%) areas followed by the lowland (25.5%) or mountainous (15.2%) areas. No statistically significant differences were observed in relation to sex (females, 33.3%; males, 24.4%, P>0.05). When evaluating the prevalence of D. immitis by age, the highest prevalence was observed in dogs older than 4 years of age. Large breeds (29.6%) and the dogs living outdoors (30.2%) showed a higher prevalence in comparison to small breeds (21.4%) and the dogs living indoors (10.5%), respectively. In conclusion, according to the results of this study canine dirofilariosis had a high prevalence in Hatay province. Therefore, prophylaxis against heartworm is advisable to decrease the incidence of canine dirofilariosis.
