Turkish Journal of Veterinary & Animal Sciences

Different genotypes of infectious bronchitis virus (IBV) in poultry are circulating worldwide. The most efficient classification system for IBV genotypes is based on the complete sequencing of S1 gene, and the target organ can be trachea, kidney, oviduct, lung, esophagus, proventriculus, intestine, liver, spleen, bursa, cecal tonsils, cloaca, and testis. In Iran, IBV genotyping is usually performed by partial sequencing of S1 gene, and the trachea is often selected for sampling. This study applies a different genotyping method, and compares the results with the routine method of genotyping. Samples were collected from the trachea and kidneys of 50 broiler flocks …

Turkish Journal of Veterinary & Animal Sciences

Ticks are well known as hematophagous ectoparasites, which cause different diseases in humans and animals. This investigation was designed in central Iran to assess the prevalence, intensity, and abundance of tick infestation in stray dogs and detection of Ehrlichia canis. Overall, 962 ticks were collected from 260 stray dogs between April and August 2018. DNA samples with the goal of amplification of pathogen were screened by real-time PCR assay. The prevalence of tick infestation on stray dogs was 60.3%. Rhipicephalus sanguineus sensu lato (s.l.) was only species found in stray dogs. Out of 42 tick pools, 4 (9.5%) were positive …

BAU Journal - Health and Wellbeing

The present research sought to explore the differences between developed and underdeveloped countries on the Love of Life Scale (LLS). Nine samples (N =3,799) took part in the study. They were university students from Egypt, Lebanon, Kuwait, Qatar, Algeria, Malaysia, India, Iran, and USA. Sex-related differences in LLS were significant only in Kuwait (in favor of males) and India (in favor of females). The samples of Malaysia and U.S.A. obtained the highest mean LLS score, followed by participants from Qatar, India, and Kuwait, (males), and India, Iran, Qatar, and Algeria (females), respectively. The Pearson correlation of LLS with the World …

Turkish Journal of Veterinary & Animal Sciences

Trypanosoma evansi is a blood parasite protozoan that causes trypanosomiasis or surra in a variety of economically valued animals such as cattle and camels. This infection causes abortion in camels. The present study was conducted to evaluate the presence of Trypanosoma evansi in aborted fetuses of Iranian camels (Camelus dromedarius) by polymerase chain reaction (PCR) method. In this study, 244 abomasal contents of aborted fetuses were collected from an Iranian camel herd in the east of Iran. The results showed that 41 of 244 (16.8%) aborted fetuses were infected with Trypanosoma evansi DNA. The results showed that a high percentage …

Turkish Journal of Veterinary & Animal Sciences

This study aims to evaluate Mycoplasma gallisepticum (MG) genetic diversity through the complete sequencing of the pvpA gene among six MG isolates present in industrial poultry from 2015 to 2016. The genetic comparison of these six isolates showed similarities of over 94% and 92% in terms of nucleotide and amino acid sequences, respectively. The size of the PvpA protein in the studied isolates included three different sizes with 361, 364, and 366 amino acids. The carboxy-terminus of the studied PvpA proteins contained 11 tetrapeptides of P-R-P-M/Q/N motifs with truncation in the proline-rich region. Based on the BLAST analysis, the pvpA …

Turkish Journal of Veterinary & Animal Sciences

Ticks are the main hematophagous arthropods and obligatory ectoparasites that are considered a vector of serious pathogens for animals and humans. The aims of the present survey were to assess the prevalence and diversity of ticks in cattle in Southeast Iran and to determine Coxiella burnetii in the ticks. From May 2014 to April 2015, 583 ticks were collected randomly from 257 cattle. Nested trans-PCR was performed to detect C. burnetii. The overall prevalence of hard tick infestation on cattle was 56.8%. In total, seven different species were identified: Rhipicephalus sanguineus sensu lato (32.6%), Hyalomma anatolicum (28.8%), Hyalomma excavatum (19%), …

Newcastle disease (ND) is one of the most serious diseases amongst many species of birds and causes huge economic losses in the poultry sector. Backyard poultry are the main source of food in rural areas of many developing countries and play a crucial role in the epidemiology of ND. The sequence of the F protein cleavage site is the major virulence determinant of Newcastle disease virus (NDV). The aim of this study was to understand the molecular characterization of F proteins of Iranian backyard poultry in NDVs. The complete open reading frame sequences of the F gene of six isolates …

Phylogenetic Analysis Of Ns Gene Of Avian Influenza Viruses (H9n2) Isolated From Chicken In Iran During 2007-2011, Hassan Norouzian, Hessam Emadi Chashmi, Ziba Nazari, Mehdi Vasfi Marandi

Turkish Journal of Veterinary & Animal Sciences

To determine sequence characteristics and phylogenetic relationships of the nonstructural (NS) gene, the NS genes of 9 avian influenza (AI) viruses were sequenced and compared with other Iranian AI H9N2 viruses available in GenBank. The similarity among the earliest Iranian H9N2 isolate (A/chicken/Iran/ZMT-101/1998) and recent (2007–2011) studied isolates was low (94%). Some of the studied viruses revealed substitutions in RNA-binding and effector domains as well as antigenic regions of the NS protein. Recently studied isolates have a high similarity (97.4%-98.7%) with some Pakistani isolates (like A/chicken/Sawabi/NARC-2434/2006) in the NS gene. In the phylogenetic analysis, recently studied isolates composed a cluster …

During the period from December 2008 to September 2009, we examined 254 serum samples (164 in hot-dry weather and 90 in cold-dry weather) from dromedary camels distributed all over Yazd Province, in the center of Iran. IgG antibodies were assayed by the modified agglutination test (MAT) and Neospora agglutination test (NAT) using whole tachyzoites of Toxoplasma gondii and Neospora caninum, incorporating 2-mercaptoethanol, for T. gondii and N. caninum, respectively. Anti-T. gondii antibodies were found in 37 (14.56%) of 254 camels with titers of 1:20 in 7, 1:40 in 6, 1:80 in 8, 1:160 in 1, 1:200 in 4, 1:400 in …

Turkish Journal of Veterinary & Animal Sciences

A large number of birds in 3 pigeon flocks (containing 637 individuals) were severely affected by Hadjelia truncata. This was observed in April 2011 in Sistan District in Iran. In the affected birds, progressive weight loss, weakness, and death were observed. In the necropsy of 8 cases the gizzards were larger and softer than normal and in all of them distortion was detected. Stool examination by the Clayton Lane method revealed 72% infection among domestic pigeons. The hematological analysis of affected birds showed signs of decline in hematocrit and total protein volume. A levamisole treatment program could successfully remove the …

Turkish Journal of Veterinary & Animal Sciences

Following deaths in a flock of Golden Pheasants, Chrysolophus pictus, in Mazandaran Province, northern Iran, during June 2008, necropsies of dead birds were undertaken and revealed a heavy mixed infection of Heterakis isolonche and H. gallinarum in the caeca, which were heavily swollen with gross nodules on the surface. Infected caeca were studied histopathologically and surviving birds were treated with fenbendazole 2.5% (20 mg/kg), with a second course 3 weeks later. No further mortality was seen in the flock. This is the first documented report of Heterakis isolonche in Iran, and also the first report of a concurrent infection of …

Turkish Journal of Veterinary & Animal Sciences

Avian influenza (AI) is an infectious disease of birds caused by type A strains of the influenza virus. Among these AI viruses, only serotypes H5 and H7 are considered highly pathogenic in poultry. However, serotype H9N2 has also been found to produce severe respiratory tract infections in chickens. Migratory birds of the world are a natural reservoir of influenza viruses of all subtypes. This is the first report of isolation and molecular survey of AI virus from migratory and wild resident birds in Boushehr, Iran. These areas are at risk for the spread and transmission of influenza A viruses. A …
