  • PERCENTAGE PREVALENCE OF EIMERIAN SPECIES IN AWASSI SHEEP IN NORTHERN OF PALESTINE
  • Published at:ASIAN ACADEMIC RESEARCH JOURNAL OF MULTIDISCIPLINARY
  • The prevalence and the species of Eimeria oocysts in 180 fecal samples of immature and adult domestic Awassi sheep were screened in 16 farms in four provinces northern Palestine, the overall incidence of the all types of coccidian oocysts was 68.75%. The prevalence of the oocysts in was significantly higher (p<0.05) in farms in Tubas (mean 100%) compared to Jenin (mean 75%), Nablus (mean 50%) and Tulkarem (mean 50%). The prevalence of the oocysts was significantly higher (p<0.05) in immature sheep (less than one year) with mean of 60% compared to adult sheep (more than a year) with mean of 40%. Eight species of Eimeria were indentified, they (and their prevalence) were E. Crandalis (18.88%), E. Parva (14.44%), E. Intricata (12.77%), E. Ovina (10%), E. Ahsata (8.88%), E. Ovinoidalis (8.33%), E. Pallida (7.22%) and E. Faurei )%6666(, a single infection was not observed, all of the infected sheep had mixed infections with two to five species.

  • Seroprevalence of Toxoplasma gondii in Goats in Two Districts in Northern Palestine
  • Published at:Walailak J Sci &amp;amp;amp;amp; Tech
  •  
    The objective of this study was to investigate the presence of anti-T. gondii in goats raised on farms in the Jenin and Tulkarm districts in the north of Palestine. The investigation was conducted on 14 herds comprising of 280 goats. Blood samples were collected via the jugular veins of 151 goats during the period from January to December 2011. The indirect ELISA test was used for the detection of anti-T. gondii antibodies. Results showed that an anti-T.gondii IgG antibody was detected in 13.4 % of the samples. The presence of the anti-T. gondii antibody was influenced by the location of the goat herds. The highest incidence was in Jenin district (17.44 %) while it was 7.69 % in Tulkarm district. These results indicated the possible contamination of meat and milk of the goats with this parasite, which in turn negatively affects human health.

  • Prevalence of the red mite (Dermanyssus gallinae) in layer flocks in four districts in northern West Bank, Palestine
  • Published at:Open Journal of Animal Sciences
  • An experiment was conducted to investigate the prevalence of the red mite (Dermanyssus gallinae) in layer farms in four districts of northern West Bank, Palestine. The four districts were: Nablus, Tulkarm, Tubas, and Jenin. A total of 225 layer farms were investigated for infection with the parasite during the period from September 2009 to August 2010. The highest prevalence of the red mite was observed in the district of Tulkarm (18.3%, 25.5%, 32.7% and 47.3%, for the districts of Nablus, Jenin, Tubas, and Tulkarm, respec-tively) which can be explained by the hot humid climate in the district and insufficient cleaning. Infection with the red mite was highest in sum-mer (43.8%) and lowest in winter (12%). The high infection rates observed in this study reflect the poor management and housing conditions, char- acteristic of layer farms in the study region.

  • Prevalence and Diversity of Gastrointestinal Parasites in small Ruminants Under Two Different Rearing Systems in Jenin District of Palestine
  • Published at:An - Najah Univ. J. Res. (N. Sc.) Vol. 26, 2012
  • This study was undertaken to investigate the prevalence of gastrointestinal parasites (GIP) in goats and sheep kept under extensive and intensive management systems in the district of Jenin, Palestine, during the period from January to December 2010. Factors affecting diversity, distribution and intensity of infection by GIP were investigated.
    Data about farm history and breeding management were collected by means of a questionnaire. A total of 810 faecal samples from small ruminants composed of 285 and 525 samples from intensive and extensive rearing systems, respectively, were collected from eight villages (Yamoun, Bet qad, Merkah, Talfeet, Kfaret, Tarem, Jab`a and
    Aneen). A total of thirteen genera of the GIPs, included (eleven nematodes, one cestode (Moniezia) and one protozoan (Eimeria) were recovered. The results showed fewer diversity of GIP in intensive rearing system. The prevalence of GIPs in animals reared under extensive system (26.5%) was significantly higher (P<0.01) than those

  • Prevalence of Toxocara canis in Dogs, North West Bank of Palestine
  • Published at:Korean J Parasitol. Vol. 49, No. 2: 1-2, June 2011
  •  
    This study was performed to investigate the prevalence of Toxocara canis in local districts in North West Bank of Palestine. Fecal samples from 132 dogs were collected in Nablus, Tulkarm, and Jenin cities from September 2008 to April 2009 and examined for T. canis eggs with the floating technique. The overall infection rate of toxocariasis in dogs was 36.4%. The dogs less than 6 months old showed higher infection rates than those older than 12 months (P = 0.04). Vigorous interventions are necessary, such as routine coprological examinations of dogs and prescription of anthelmintics to infected dogs.
