Dromedary camels are the most vulnerable animals to penile and preputial pathology due to the aggressive nature of mating and injuries during transit, which could impair the semen quality. Hence, this study was performed to monitor the penile and preputial pathological conditions in male dromedary camels, as well as their impact on epididymal spermatozoa, by utilizing computer-assisted sperm analysis (CASA) and correlation analysis with testosterone concentrations. A total of 60 male dromedary camels were examined for penile and preputial pathological problems.

A balanced approach that combines trade policies, renewable energy promotion, and robust environmental regulations is crucial for improving ecological sustainability. Although the literature suggests that trade openness facilitates the transfer of cleaner energy technologies to developing nations, existing empirical studies have produced inconclusive results, particularly in Somalia's context. Therefore, this study explores the dynamic relationships between renewable energy, trade openness, economic growth, globalisation, and environmental degradation using annual time-series data from 1990 to 2019.

Background: Although several risk factors have been suggested for uterine torsion, the pathogenesis is still unclear. Therefore, the current study aims to investigate the pathogenesis of uterine torsion by assessing the histological, histochemical, and immunohistochemical changes that occur in the placenta obtained from uterine torsion cases. Immunohistochemical changes include investigation of the expression of estrogen receptors (ERs), progesterone receptors (PRs), and the vascular endothelial growth factor (VEGF) in the placental tissue.

The study was designed to monitor the cleavage rate (CR) and in-vitro cultivation rate (IVC) after addition of energy sources, non-essential amino acids, and antioxidants to the Synthetic oviductal fluid (SOF) and FertiCult. After in-vitro maturation and in-vitro fertilization, presumptive zygotes were cultured in one of two culture media: FertiCult media and SOF medium, supplemented with pyruvate, glucose, and sodium lactate as energy sources, as well as 10, 20, 250, 500, and 750 mg non-essential amino acids, and antioxidants. All stages of cleavage rate (CR), and in-vitro cultivation rate (IVC) of embryonic development including morula stage (MOR) and blastocyst (BLAS) have been assessed.

Article Synopsis
  • - The study explored how amino acids, specifically histidine and L-Tyrosine, affect various stages of buffalo embryo development, including maturation, fertilization, and cultivation.
  • - Results indicated that a specific concentration of histidine (0.5 mg/ml) significantly improved oocyte maturation, while L-Tyrosine at certain concentrations enhanced embryonic development into morula and blastocyst stages.
  • - Overall, adding histidine and L-Tyrosine to the culture media positively impacted the maturation rates of buffalo oocytes and the development of embryos in vitro.

To predict the sex of the foetus, healthy pregnant dromedary camels (n = 24) were included. Blood samples were collected for measurements of progesterone, estradiol, testosterone, and cortisol as well as total proteins, albumin, glucose, creatinine, blood urea nitrogen, phosphorus, calcium, creatine kinase, alanine aminotransferase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), gamma glutamyl transpeptidase (GGT), calcium, phosphorus, and magnesium. Statistical analysis revealed differences between pregnant camels and pregnant camels in terms of female or male foetuses depending on the actual sex of the born calf.

Brucellosis poses a major public and animal health problem in many parts of the world, particularly in pastoral settings, however, seroepidemological studies are scarce. A cross-sectional study was conducted from December 2021 to April 2022 to estimate the prevalence of brucellosis and to identify the associated risk factors for camels and occupational individuals from three purposively selected districts of the Somali pastoral region in Eastern Ethiopia. Serum samples were serially diluted using the Rose Bengal Plate Test (RBPT) as a screening test and a competitive Enzyme-Linked Immunosorbent Assay (cELISA) test as a confirmatory test.

The study aimed to assess the effects of water salinity on the sperm parameters, levels of cortisol, LH, FSH, testosterone and antioxidants as well as the testes' histopathology in Barki rams. Fifteen healthy Barki rams (1-1.5 years) were divided into three equal depending on the type of drinking water for nine months.

Semen cryopreservation is an important tool that has massively contributed to the progression of animal reproduction, especially in cattle. Nonetheless, a large part of the sperm population suffers from cryostress and loses fertility during the process. Although bovine semen cryopreservation is more advanced than any other species, there are still some missing links in the technology knowledge.

  • A cross-sectional study conducted from May 2017 to March 2019 assessed camel calf health issues and traditional management practices while prioritizing economically important diseases.
  • The study identified major challenges to camel production, including high rates of diseases like camelpox and pneumonia, poor husbandry practices, and limited resources such as feed and water.
  • It also highlighted the prevalence of specific diseases, including a 74% rate of diarrhea primarily caused by E. coli and Salmonella, and recommended improvements in veterinary health infrastructure and community awareness to support better camel calf rearing.

  • A cross-sectional study in eastern Ethiopia assessed the prevalence and risk factors of bovine tuberculosis (BTB) in cattle, finding infection rates of 11.24% at the individual level and 43.3% at the herd level.
  • Key risk factors included poor body condition scores, age, seasonal migration, parity number, and reproductive status, with poor body condition significantly increasing the likelihood of testing positive.
  • The study also indicated a low level of awareness among local herders regarding BTB and its transmission to humans, highlighting the urgent need for effective control and prevention strategies.

Ticks are a common parasite that affect many animals by causing slowed growth, reduced milk output, and financial losses for industries that depend on animal hides and skins. From June to December 2017, participatory and conventional investigations on tick infestation in camels and cattle were conducted in Kebribayah and Afdem districts of Ethiopia's Somali Regional State. The aim of this study was to determine the prevalence and density of ticks in these animals and establish strategic control measures to enhance livestock productivity and livelihoods in pastoral areas.

Background: The incidence of stroke in the Middle East is high, given its relatively young population. Smoking is a well-recognized risk factor for ischaemic stroke, and its high regional prevalence may partly account for this increased stroke risk. This research aims to determine whether young male South Asian migrants in Qatar were adversely affected by stroke depending on their smoking status.

Introduction: The World Health Organization recommends regular monitoring of the efficacy of nationally recommended antimalarial drugs. We present the results of studies on the efficacy of recommended antimalarials and molecular markers of artemisinin and partner resistance in Afghanistan, Pakistan, Somalia, Sudan and Yemen.

Methods: Single-arm prospective studies were conducted to evaluate the efficacy of artesunate-sulfadoxine-pyrimethamine (ASSP) in Afghanistan and Pakistan, artemether-lumefantrine (AL) in all countries, or dihydroartemisinin-piperaquine (DP) in Sudan for the treatment of Plasmodium falciparum.

Ebola virus disease (EVD) is a severe and highly fatal zoonotic disease caused by viruses in the family and genus . The disease first appeared in Zaire near the Ebola River in 1976, now in the Democratic Republic of the Congo. Since then, several outbreaks have been reported in different parts of the world, mainly in Africa, leading to the identification of six distinct viral strains that cause disease in humans and other primates.
