Abstract The bacterium Avibacterium paragallinarum , previously known as Haemophilus is responsible for causing infectious coryza (IC) in chickens and other avian species. In this case report, an outbreak of occurred the Qinling area China, resulting clinical symptoms facial swelling several bird species, including Golden pheasant, Temminck's tragopan, Peafowls, three pheasants died due to prol...

The parasites of genera Haemoproteus, Plasmodium, and Leucocytozoon are well-known avian haematozoa and can cause declined productivity and high mortality in wild birds. The objective of the study was to record the prevalence of haematozoan parasites in a wide range of wetland birds in Bangladesh. Six species of Haemoproteus, seven species of Plasmodium, one unidentified species of Leucocytozoo...

voluntary muscles of the same individual. The encysted or infective stage larvae in the muscles, reach a length of approximately one m.m. The parasite is found in many carnivorous and omnivorous warm-blooded animals. Birds are not susceptible to this infection and from the point of view of transmission, birds do not play, a part. The same is the case with cold blooded animals which cannot be in...

West Nile virus (WNV) has caused disease in humans, equids, and birds at lower frequency in Mexico than in the United States. We hypothesized that the seemingly reduced virulence in Mexico was caused by attenuation of the Tabasco strain from southeastern Mexico, resulting in lower viremia than that caused by the Tecate strain from the more northern location of Baja California. During 2006-2008,...

To study the course of natural avian bornavirus (ABV) infection, 63 psittacines of three bird collections where ABV had been demonstrated were investigated over a period of 1 yr. The psittacines were clinically observed and swabs of crop and cloaca as well as serum samples were collected three separate times at intervals of 2-6 mo. According to the results of detection of ABV RNA by reverse tra...

The prevalence of cryptosporidial infection among captive wild animals and birds in Sanda Kyarimi Park, Maiduguri, north-eastern Nigeria, was evaluated by faecal examination for oocysts using three different staining techniques: the modified Ziehl-Neelsen, Giemsa, and Safranin-methylene blue. A total of 66 captive wild animals and birds were examined based on age and sex differences. Fifteen (2...

To gain more insight in underlying mechanisms correlating to protection against avian influenza virus (AIV) infection, we investigated correlates of protection after AIV H9N2 infection and studied the contribution of different adjuvants to a protective response at host transcriptional level. One-day-old chickens were immunised with inactivated H9N2 supplemented with w/o, Al(OH)(3), CpG or witho...

most highly pathogenic avian influenza viruses (aiv) emerge after field passage of non-pathogenic aivs in birds. the outbreak of low-pathogenic h7n1 avian influenza virus in italy during 1999-2000 followed by outbreak of highly pathogenic h7n1 avian influenza virus is one example in this regard. this experiment has been designed to investigate the effect of pre-infection of birds with lpai on s...

Avian pathogenic Escherichia coli (APEC) causes morbidity in chickens and exhibits zoonotic potential. Understanding host transcriptional responses to infection aids the understanding of protective mechanisms and serves to inform future colibacillosis control strategies. Transcriptomes of spleen and peripheral blood leukocytes (PBLs) of the same individual birds in response to APEC infection we...

Psittacosis, also known as parrot fever and ornithosis, is a bacterial infection of humans that can cause severe pneumonia and other serious health problems. It is caused by Chlamydophila psittaci, formerly known as Chlamydia psittaci. From 1988 through 2003, 935 human cases of psittacosis were reported to the CDC and most resulted from exposure to infected pet birds, usually cockatiels, parake...
