Bayesian true prevalence estimation of brucellosis in sheep, goats, cattle and camels in southeast regions of Iran.

Aims And Methods: Brucellosis is worldwide one of the most prevalent zoonotic diseases with serious public health hazard affecting domestic livestock and causing economic losses. Objective of this study is to estimate the true prevalence of brucellosis in livestock, specifically cattle, sheep, goats and camels, using a novel Bayesian latent class model, adjusting for the imperfect sensitivity and specificity of the applied tests, where the second test was restricted only to first test-positive samples.

Results: Brucellosis seems more prevalent in goats and sheep, while the posterior medians and 95% probability intervals (95% PI) for the average true prevalence for sheep, goats, cattle and camels are 18% (4%-43%), 19% (7%-37%), 16% (5%-34%) and 18% (1%-48%) respectively.

Echocardiographic assessment of intravenous administration of medetomidine and xylazine hydrochloride at different sedative doses in one-humped camel calves ().

Echocardiography illustrates a convenient and noninvasive tool for measuring cardiac output (CO) changes after administration of sedative drugs, but it is unknown in camelids practice. The aim of present study was to investigate echocardiographic effects of intravenous (IV) injection of medetomidine and xylazine in camel calves. Twenty apparently healthy immature male one-humped camel calves () were divided into four groups (five animals in each treatment).

Comparative evaluation of the sedative and physiological effects of medetomidine alone and in combination with pethidine, morphine, tramadol, and methadone in goats.

Background: The use of combinations of α -adrenergic agonists and opioids has been published as providing superior sedation than either drug alone.

Introduction: The present study aims to compare the sedative and physiological effects of intravenous (IV) administration of medetomidine alone and in combination with methadone, morphine, tramadol, and pethidine in goats.

Methods: Ten healthy goats aged 12 ± 3 months and weight of 22 ± 4 kg were used in an experimental, crossover (Latin square), randomized, and blinded study.

Observed and expected combined effects of metritis and other postpartum diseases on time to conception and rate of conception failure in first lactation cows in Iran.

Previous observational studies have produced strong evidence that metritis alone has an impact on reproductive performance in dairy cows; but few studies have examined the combined effect of metritis and other postpartum diseases on reproduction performance in dairy cows. Information on the combined effects of postpartum diseases on fertility in dairy cows can have practical herd-health management implications. The objective of the study reported here was to examine the observed and expected combined effects of metritis and other postpartum diseases (retained fetal membranes (RFM), clinical hypocalcemia, left displaced abomasum, clinical mastitis, lameness) on time to conception and rate of conception failure in first-lactation cows up to 150 days postpartum.

Serological evidence of leptospirosis in Iran; A systematic review and meta-analysis.

Leptospirosis is a neglected infectious zoonotic disease that affects domestic animals and wildlife as well as humans. Although leptospirosis is known as an endemic disease in Iran, there is no accurate information on the overall prevalence of this disease in humans and animals. The aim of this systematic review and meta-analysis was to estimate the seroprevalence of leptospirosis among human and domestic and wild animals in Iran.

Evaluation of sedative, analgesic, physiological, and laboratory effects of two doses off medetomidine and xylazine in dromedary calves.

The present study aims to comparatively evaluate the effects of different doses of intravenous xylazine and medetomidine on sedation and antinociception scores, and physiological and laboratory parameters in dromedary calves. Thirty clinically healthy male dromedary calves 15 ± 2 weeks old and weighing 95 ± 5.5 kg were studied.

In vitro effects of Artemisia sieberi on Echinococcus granulosus protoscolices.

Hydatidosis is a parasitic zoonotic disease. Surgery is one of its treatment modalities during which protoscolices are likely to be released into the peritoneal cavity and cause recurrence of the disease. Given the above problem and the complications associated with conventional anti-parasitic agents, it is imperative to find an effective and natural protoscolicidal agent.

Detection of pancoronavirus using PCR in in Iran (first report).

is a colossal family of viruses that cause a variety of diseases in humans and other animals. As of late, a novel coronavirus, not anterior-optically discerned in humans, has been identified in a denizen of the Middle East. There is growing evidence that the is host species for the virus and plays an important role of a source of human infection.

First serological study of equine hydatidosis in Iran.

Hydatidosis, is an important worldwide zoonotic disease caused by larval stages (metacestodes) of tapeworm parasites of the genus Echinococcus. The objective of the present study was to determine the seroprevalence of equine hydatidosis in Iran by latex agglutination test. This study also served to correlate sex and age with mentioned results in cases.

Seroprevalence of bovine leptospiral antibodies by microscopic agglutination test in Southeast of Iran.

Objective: To evaluate serological findings of bovine leptospirosis which is a zoonotic disease with worldwide distribution caused by Leptospira interrogans.

Methods: One hundred and sixty seven sera were collected from 9 commercial dairy herds in jiroft suburbs, from July to October 2011. Microscopic agglutination test (MAT) was used to evaluates serological findings of bovine leptospirosis in Jiroft suburb dairy farms, Kerman province, Iran.

Haematological and biochemical alterations caused by epidural and intramuscular administration of xylazine hydrochloride in dromedary camels (Camelus dromedarius).

This study was conducted in 16 healthy immature dromedary camels weighing 120-150 kg to evaluate and compare the effects of epidural and intramuscular injections of xylazine administered at 0.1 mg/kg and 0.2 mg/kg.

Epidural ketamine in the dromedary camel.

Objective: To evaluate the clinical and physiological effects of epidural injection of ketamine in camels.

Study Design: Randomized prospective study.

Animals: Ten healthy immature male dromedary camels.

Herd-prevalence of Coxiella burnetii (Q fever) antibodies in dairy cattle farms based on bulk tank milk analysis.

Objective: To determine the prevalence of Coxiella burnetii (C. burnetii) antibody positive randomly selected dairy herds in southeast Iran (Kerman).

Methods: Bulk tank milk samples were collected randomly from 44 sufficiently large commercial dairy herds, included near 12 000 dairy cattle, in Kerman (The largest province of Iran), southeast Iran.

Detection of leptospiral antibodies by microscopic agglutination test in north-east of Iran.

Objective: To detect leptospiral antibodies by microscopic agglutination test (MAT) in north-east of Iran.

Methods: This study was conducted to evaluate prevalence of human leptospiral infections by MAT, using six current reference strains of Leptospira interrogans in north-east of Iran. A total of 285 serum samples were collected from three north-east provinces of Iran, from December, 2009 to June, 2010.

The first serologic study of Q fever in sheep in Iran.

Coxiella burnetii is an obligate intracellular microorganism that causes Q fever in humans and animals. In ewes, C. burnetii infections are generally asymptomatic, but they can lead to abortions, stillbirths, and delivery of weak and unviable lambs.

An update on a serologic survey of Q Fever in domestic animals in Iran.

The aim of this study was to investigate the presence of Coxiella burnetii antibodies among goat and dairy cattle herds in southeast Iran. A total of 169 sera (76 caprine samples from 9 goat flocks and 93 bovine samples from 12 dairy herds) were collected randomly. The CHEKIT Q fever ELISA kit was used to identify specific antibodies against C.
