Seroprevalence of Ornithobacterium rhinotracheale Infection in Broiler and Broiler Breeder Chickens in West Azerbaijan Province, Iran

Abstract

Ornithobacterium rhinotracheale is a pleomorphic Gram-negative rod shaped bacterium of the rRNA superfamily V that is associated with respiratory disease in poultry. This study was conducted to determine the seroprevalence of O. rhinotracheale infection in broiler and broiler breeder chickens in West Azerbaijan (Urmia lake region) by using a commercial enzyme-linked immunosorbent assay. In this study, 463 serum samples were obtained from 50 broiler flocks and 472 blood sera from 42 broiler breeder flocks. Results showed that 41 broiler flocks (82%) and 39 broiler breeder flocks (92.8%) were positive. Ornithobacterium rhinotracheale antibodies were detected in 205 (44.2%) of the 463 broiler serum samples. Of the 472 blood sera examined from broiler breeder, 340 (72%) were positive. The results of this study indicated that the prevalence of O. rhinotracheale antibodies is high in the broiler and broiler breeder flocks in West Azerbaijan.

Serologic prevalence of Ornithobacterium rhinotracheale infection in commercial layers

“…Hafez and Sting (1996) announced that O. rhinotracheale specific antibodies were detected in 26% of broiler serum samples in Germany. Also, antibodies against O. rhinotracheale were detected in 52% of the tested sera of layers by Heeder et al (2001) Allymehr (2006) and Rahimi (2014), respectively. However, in Thailand, 19.6% of tested broiler serum samples were found positive for O. rhinotracheale (Chansiripornchai et al 2007).…”

“…rhinotracheale infections have been reported from Belgium, Iran, Germany, United States, South Africa, Netherlands, France, Israel, Hungary, Japan, United Kingdom and Turkey (Charlton et al 1993, Hinz et al 1994, Van Beek 1994, Dudouyt et al 1995, Travers 1996, Hafez 1998, Sakai et al 2000, Banani et al 2002, Turan and Ak 2002, Allymehr 2006, Rahimi and Banani 2007. In Turkey, presence of O. rhinotracheale infections in broiler, layer and turkey flocks has been announced over the last decade by some researchers (Erganiş et al 2002, Turan and Ak 2002, Özbey et al 2004, Türkyılmaz 2005, Türkyılmaz and Kaya 2005, Erganiş et al 2013.…”

<i>Ornithobacterium rhinotracheale</i> Infection in Poultry: an Updated Review

“…However, O. rhinotracheale excretion and its antibody response may also be affected by a number of factors such as antibiotic therapy and vaccination (Hafez, 2002). ELISAs, serum plate agglutination tests, and a dot-immunobinding assay have been reported for the detection of O. rhinotracheale antibodies (Back et al, 1998;van Empel and Hafez, 1999;Sakai et al, 2000;Erganiş et al, 2002;Hafez, 2002;Canal et al, 2003a;Allymehr, 2006;Eroksuz et al, 2006;Chansiripornchai et al, 2007;Ghanbarpour and Salehi, 2009;Uriarte et al, 2010;Walters et al, 2010).…”

“…ELISAs have been developed using different serotypes and extracted antigens of O. rhinotracheale , and both self-made and commercially available ELISAs (Biochek, Inc., USA, and IDEXX Laboratories, Inc., USA) are used to detect antibodies against most O. rhinotracheale serotypes (Hafez, 2002 (Canal et al, 2003a;Allymehr, 2006;Chansiripornchai et al, 2007;Ghanbarpour and Salehi, 2009;Uriarte et al, 2010).…”

Prevalence of etiological agents of selected respiratory infections in chicken and turkey farms in the Czech Republic

“…The antibiotics of choice are tetracycline, chlortetracycline and amoxiciline. High seroprevalences of O. rhinotracheale infection have been recorded in some countries in Europe and Asia, especially in Germany 26% (Hafez and Sting 1996), in Turkey 62.5% (Turan and Ak 2002) and in Iran 44.2% (Allymehr 2006), mostly in broiler flocks.…”
