Flock-level seroprevalence of, and risk factors for, Neospora caninum among sheep and goats in northern Jordan

Background. Infectious diseases of the respiratory tract of farm animals are caused by a combination of infectious agents and predisposing factors. Parainfluenza virus type 3 is usually nominated as one of the causes. Seroprevalence and animal risk factors for PI3 infections were investigated in northern Jordan. Methods. The study involved 104 small ruminant flocks (18 sheep, 27 goats, and 59 mixed flocks sampled in northern Jordan. Indirect ELISA was used to test 678 blood samples used in this study. Flocks were identified as infected if at least 1 animal has been detected as positive by the ELISA test. Information regarding production and health management practices was collected in a questionnaire. Statistical analysis was conducted using the Statistical Package for Social Sciences software SPSS 23 (SPSS Inc., Chicago, IL, USA). Results. Flock-level and individual-level seroprevalences were 97%, 37%, and 76%, 11% in sheep and goats respectively. Multivariable logistic regression applied for production and health management practices showed significant risk factors for: Climatic zone (OR= 0.3) was decreasing risk factor for the PI3 seropositivity. Young separated from dams (OR= 4), neonatal deaths (OR= 3), and milking manual (OR= 37.5) were increasing risk factors for the seropositivity of PI3. Conclusions. PI3 virus has a high prevalence in sheep than goats and two risk factors could increase the prevalence of PI3 in both sheep and goats.

Northern Jordan

During 2002-2003 the seroprevalence of Mycoplasma capricolum subsp. capricolum was studied among 104 small ruminant’s flocks (18 sheep, 27 goat and 59 mixed flocks) in northern Jordan. At least 5 serum samples/flock were tested using iELISA test. The true flock-level seroprevalences of Mycoplasma capricolum subsp. capricolum were 56%, 39%, 28% in small ruminant (sheep and goats), sheep and goats respectively. There was no significant difference (X2 = 2, d.f. =1, p = 0.15) between seroprevalences in sheep and goats at the flock level. A total of 29 variables including production and health management practices were tested as risk factors for seropositive flocks and analyzed using logistic regression analysis. The use of communal grazing was found to be a risk factor for Mycoplasma capricolum subsp. capricolum seropositivity with odds ratio of 5.2 and drinking the animals with spring water was a protective factor with odds ratio of 0.27. More than half of the examined flocks were seropositive to Mycoplasma capricolum subsp. capricolum indicating a role for Mycoplasma capricolum subsp. capricolum in contagious agalactiae in small ruminants. The education of farmers regarding the use of communal grazing and housing the newborn in separate barns is expected to help reducing the Mycoplasma capricolum subsp. capricolum infections in their flocks.

Serological Investigation

The objective of this study was to investigate the prevalence of anti-Neospora caninum antibodies in cattle from milk producing farms of the microregion of Batalha, state of Alagoas, Brazil, as well as to identify the risk factors associated with the infection. Blood samples were collected from 1,004 cattle of 17 farms for the serological investigation regarding the presence of anti-N. caninum antibodies by the Indirect Immunofluorescence Reaction Technique (IMRT). From the total amount of samples analyzed, 77/1,004 (7.67%) were positive and 927/1,004 (92.33%) were negative. The logistical regression identified that cattle from farms without consortium breeding have an infection risk 6.33 (p<0.001; C.I. 2.89-13.10) times higher than cattle from farms with that type of breeding. Cattle from farms where the aborted fetuses are not adequately buried have an infection risk 3.04 (p<0.001; C.I. 1.64-5.63) times higher than cattle from farms with adequate destination of these fetuses. Infection by N. caninum occurs in cattle of the investigated region. The factors identified in our study can be used as risk indicators, so that control measures could be implemented to avoid infection by N. caninum in the herds of this region.
