Seroprevalence of Q fever in sheep and goats from the Marmara region, Turkey
2019
Karagul, Mustafa Sencer | Malal, Mehmet Engin | Akar, Kadir
The aim of this study was to investigate Q fever seroprevalence in sheep and goats in the Marmara region. Q fever is a zoonotic disease caused by Coxiella burnetii. In ruminants, the disease causes reproductive disorders, premature births and stillbirths. Blood samples of sheep and goats were collected from the Marmara region of Turkey and a commercial ELISA was used for detection of specific antibodies to C. burnetii. A total of 832 samples (627 from sheep and 205 from goats) obtained from 126 herds located in 110 villages in 63 municipalities across all 11 provinces were utilised. Total seroprevalence was found to be 13.22%, while the proportion of seropositive herds was determined to be over threefold higher at 42.85%. The seroprevalence for sheep was found to be 14.19%, and for goats 10.24%. The herd seropositivity rate for sheep of 46.31% and for goats of 32.25% were also over threefold higher than the species-level seroprevalences. The provincial seroprevalence varied between 1.38% and 21.79%. This study confirms the presence of C. burnetii in sheep and goat herds in the Marmara region and provides original seroprevalence data in hitherto uninvestigated provinces. The data gathered are beneficial for evaluation and elaboration of the seroprevalence of Q fever in sheep and goats in the Marmara region. Surveillance studies should be maintained, particularly in provinces with high seropositivity rates.

Fodder quality and availability are major determinants in profitable ruminant production system. Tamil Nadu Veterinary and Animal Sciences University and Department of Animal Husbandry, Government of Tamil Nadu and other related institutions promote fodder production through several schemes and projects. Intensive fodder production through promotion of sustainable fodder production model under irrigated condition is one among them. The objective of the present study was to validate the fodder production potential of the ten-cent model for livestock feeding. In livestock farm complex Madhavaram, ten-cent model fodder plot was established with Hybrid Napier grass variety Co (BN) 5 in 4 cents area; fodder maize (African Tall) in 1 cent; fodder sorghum (CoFS 31) in 2 cents; fodder cowpea (Co 8) and Velimasal (Desmanthus virgatus) in 1.5 cents area each; Agathi (Sesbania grandiÀora) and Subabul (Leucaena leucocephala) were cultivated as boundary plantation. Standard agronomical management practices were adopted during the study period (15 months) and fodder was harvested at specified intervals. The total biomass yield realized was 9918 kg. The average yield/cut (kg) of Co5, sorghum, maize, cow pea, Desmanthus and Agathi/Subabul were 1340.0, 264.6, 160.0, 178.0, 71.0 and 98.0 kg respectively. Highest fodder yield was noticed during south west monsoon season (2492.0 kg) followed by north east monsoon season (1796.5 kg) and lowest yield noticed in summer season (1465.0 kg). The total CP and TDN yield (on dry matter basis) of ten-cent model fodder plot, estimated from available standards were 1121.71 kg and 5586.58 kg respectively during the study period. The results of this study revealed that quantity and quality of fodder harvested from the ten-cent model fodder plot can support one cattle or five goats for a year. It is possible to sustain one cow or five goats through fodder production in the ten-cent model fodder plot.

Objective: The main objective of this study is to design a synthetic vaccine from the binder of sperm-1 (BSP1). Materials and Methods: This study was carried out using bioinformatics-related techniques. BSP-1 has been chosen as one of the biomarkers of a ruminant's male fertility. We hypothesize that the BSP1 synthetic vaccines, which contain T-cell epitopes, can produce antibodies more effectively for the development of a sperm fertility detection kit. A sequence of BSP-1 peptides A0A0K1YXR5 from Bubalus bubalis (Domestic water buffalo) origin has been decided to be used to develop the peptide vaccine. Results: In this study, we succeeded in making synthetic vaccines from BSP-1 with a peptide sequence of LPEDSVPDEERVFPFTYRNRKHF. The three-dimensional theoretical prediction analy¬sis of the peptide binding pattern to its ligand, as well as the molecular docking, has also been revealed. Conclusions: A synthetic vaccine from the BSP-1 has been developed in this study with the amino acid sequence LPEDSVPDEERVFPFTYRNRKHF, which is buffer-soluble, and the three-dimensional theoretical prediction analysis of the peptide binding pattern of BSP-1 to its ligand, as well as molecular docking, has also been revealed.
