“…To the best of our knowledge, these were the first cases of avian pox in Japanese cormorants. Whereas APV infection is rarely fatal in most species, mortality can reach up to 50% in cases of some species [2,4,17]. In the present report, all of the affected Japanese cormorants recovered from the avian pox and did not show any signs of recurrence, which suggests that the detected APV would not result in a highly lethal infection in Japanese cormorants.…”

“…A section of P4b and DNA polymerase genes of APVs were detected by PCR using the following primers: P1X (5′-TCAGCAGGTGCTAAACAACA-3′) and P2 (5′-CGGTAGCTTAACGCCGAATA-3′) for APV P4b gene [2] and PoPr1 (5′-CGCCGCATCATCTACTTATC-3′) and PoPr2 (5′-CCACACAGCGCCATTCATTA-3′) for DNA polymerase gene of APV [3]. The expected sizes of the PCR products were 578 and 642 bp, respectively.…”

“…PCR of the P4b gene was performed with initial denaturation for 5 min at 94°C, followed by 35 amplification cycles at 94°C for 1 min, 59°C for 1 min, and 72°C for 1 min. The final extension step was performed at 72°C for 7 min, as previously described [2]. PCR carried out on the DNA polymerase gene was performed with initial denaturation for 5 min at 95°C, followed by 35 amplification cycles at 95°C for 30 sec, 53°C for 30 sec, and 72°C for 1 min.…”

“…Agar gel immune diffusion (AGID) technique using ILTV hyperimmune serum is commonly used to differentiate it from a diphtheritic form of fowlpox (Fukui et al 2016). However, the sensitivity was lower when compared with other serological techniques like virus neutralization test (Devlin et al 2011), indirect immunofluorescence test and ELISA (Jordan and Chubb 1962;Godoy et al 2013).…”

Infectious laryngotracheitis (ILT) is a highly contagious upper respiratory tract disease of chicken caused by a Gallid herpesvirus 1 (GaHV-1) belonging to the genus Iltovirus, and subfamily Alphaherpesvirinae within Herpesviridae family. The disease is characterized by conjunctivitis, sinusitis, oculo-nasal discharge, respiratory distress, bloody mucus, swollen orbital sinuses, high morbidity, considerable mortality and decreased egg production. It is well established in highly dense poultry producing areas of the world due to characteristic latency and carrier status of the virus. Co-infections with other respiratory pathogens and environmental factors adversely affect the respiratory system and prolong the course of the disease. Latently infected chickens are the primary source of ILT virus (ILTV) outbreaks irrespective of vaccination. Apart from conventional diagnostic methods including isolation and identification of ILTV, serological detection, advanced biotechnological tools such as PCR, quantitative real-time PCR, next generation sequencing, and others are being used in accurate diagnosis and epidemiological studies of ILTV. Vaccination is followed with the use of conventional vaccines including modified live attenuated ILTV vaccines, and advanced recombinant vector vaccines expressing different ILTV glycoproteins, but still these candidates frequently fail to reduce challenge virus shedding. Some herbal components have proved to be beneficial in reducing the severity of the clinical disease. The present review discusses ILT with respect to its current status, virus characteristics, epidemiology, transmission, pathobiology, and advances in diagnosis, vaccination and control strategies to counter this important disease of poultry.

This case study describes a fatal avian pox outbreak in a backyard flock of domestic ducks (Anas platyrhynchos domesticus) in Bangladesh. A total of six ducks of varying ages were affected and presented with solid tumour‐like masses on the legs. A 6.5‐month‐old female duck was presented for clinical examination, and a 2 cm3 solid, nodular mass was surgically excised from the left leg. Histopathological examination of the tumour mass revealed marked epidermal hyperplasia with ballooning degeneration and eosinophilic intracytoplasmic inclusion bodies, as well as severe proliferation and necrotising dermatitis, with marked heterophilic and histiocytic infiltration. Electron microscopy revealed numerous dumbbell‐shaped virus particles within the intracytoplasmic inclusion bodies on degenerating keratinocytes, confirming Avipoxvirus infection. This is the first case report of avian pox in ducks in Bangladesh.
