Abstract

Trypanosomiasis is one of the severe pathogenic infections, caused by several Trypanosoma species, affecting both animals and humans, causing substantial economic losses and severe illness. The objective of this study was to determine the molecular diagnosis and the risk factors associated with trypanosomiasis in District Jhang, Punjab, Pakistan. For this purpose, blood samples were randomly collected from 200 horses. A predesigned questionnaire was used to collect data on risk factors before the sample collection. The microscopy examination through Giemsa staining, formol gel test and PCR techniques were used to find the prevalence. The prevalence was recorded as 22.5% with microscopy examination, 21% through formol gel test and 15.5% with PCR based results. Analysis of risk factors associated with Trypanosoma brucei evansi occurrence was carried out using Chi-square test. It showed the prevalence of Trypanosoma brucei evansi was significantly (p<0.05) associated with sex, age, rearing purpose and body condition whereas non-significantly (p>0.05) with insects control practices. This study supports the idea that PCR is a sensitive, robust and more reliable technique to diagnose trypanosomiasis. It was concluded that Trypanosoma brucei evansi is widely prevalent in Jhang (Pakistan), highlighting a dire need to develop control strategies and education programmes to control this disease in developing countries.

Abstract

This study aimed to determine the effects of dexamethasone and minocycline alone and combined treatment with N-acetylcysteine (NAC) and vitamin E on serum coenzyme Q10 (CoQ10) and matrix metalloproteinase-9 (MMP-9) levels in rats administered aflatoxin B1 (AFB1). The study was carried out on 66 male Wistar rats. Following the intraperitoneal (IP) administration of AFB1 at dose of 2 mg/kg, minocycline (45 and 90 mg/kg, IP) and dexamethasone (5 and 20 mg/kg, IP) were administered alone and combined with NAC (200 mg/kg, IP) and vitamin E (600 mg/kg, IP). CoQ10 and MMP-9 levels were analyzed using the HPLC-UV method and a commercial kit by ELISA, respectively. AFB1 increased MMP-9 level and decreased CoQ10 level compared to the control group. After dexamethasone and minocycline administration, there is no increase in CoQ10 level, which is caused by AFB1. However, dexamethasone and minocycline combined with NAC+vitamin E caused significant increases in CoQ10 levels. Dexamethasone and minocycline alone and combined with NAC+vitamin E decreased MMP-9 levels compared to the single AFB1 treated group. The use of MMPs inhibitors and oxidative stress-reducing agents is anticipated to be beneficial in the poisoning with AFB1.

Abstract

The purpose of this study was to evaluate in detail both the in vivo and in vitro efficacy of the enzyme agents, ZYMOX® Plus Otic (ZYMOX-P), in the treatment of canine otitis externa (OE). Eight dogs with a diagnosis of non-seasonal severe chronic OE were recruited for the study. ZYMOX-P was administered for 2-4 weeks. The Otitis Index Score (OTIS3) and bacteria or yeast colony growth were measured. Also, minimum biofilm (BF) formation inhibition concentration (MBIC) and BF bactericidal concentration (BBC) were measured in vitro. OTIS3 showed a statistically significant reduction after treatment (88.2%, p<0.001; pre-treatment = 11.0 ± 0.9; post-treatment = 1.3 ± 0.4, mean ± SEM). The individual OTIS scores, erythema, edema, erosions/ ulcerations, exudate and pruritus showed significant reduction (85.7%, 95.7%, 83.3%, 80.0%, and 89.3%, respectively). Microscopic examination revealed the presence of BF exopolysaccharide in all 8 ear samples when stained with alcian blue. Seven of the 8 dogs (87.5%) showed a reduction in colony growth. ZYMOX-P was effective at 34-fold and 16-fold dilutions on MBIC and BBC, respectively. These findings indicate that ZYMOX-P has efficacy against BF-related infection and is beneficial when used for the management of canine OE.

Abstract

Classical swine fever (CSF) and porcine reproductive and respiratory syndrome (PRRS) are responsible for major economic losses and represent a threat to the swine industry worldwide. Routine surveillance serology for CSF and PRRS viruses is critical to maintaining the health status of sow farms in Hunan Province, which is one of the top pig production provinces in China. The aim of our study was to investigate the serological statistics of CSF virus (CSFV) and PRRS virus (PRRSV) in Hunan Province. The cohort serum samples were collected from vaccinated and unvaccinated pigs. Our findings showed that the average rates of CSFV and PRRSV antibody seropositivity were 82.2% (95% CI: 80.1-84.3) and 84.8% (95% CI: 82.5-87.1), respectively, in the immunized group and that these rates were higher than those in the unvaccinated group (58.6% for CSFV and 47.8% for PRRSV). Additionally, the level of CSFV antibody in piglet serum declined gradually with age, whereas PRRSV-specific antibody level increased initially (1 to 2 weeks old) and then declined with age (2 to 4 weeks old). In summary, we investigated the difference in CSFV/PRRSV antibody levels among piglets at various weeks old (1 to 4 weeks) to further establish the duration of maternal immunity in piglets. In addition, routine monitoring of CSFV/PRRSV antibodies in immunized pigs was carried out to evaluate the efficacy of vaccination.

Abstract

Nowadays, a high incidence of cutaneous tumors is observed in domestic carnivorous in pet clinic, the sebaceous glands being the starting point for the development of these tumors. The hormonal imbalances are considered to be the most common etiology for these tumors, so the current research is based on the effects of an androgenic like hormonal drug on the functionality of the sebaceous glands in dogs. For this purpose, 32 dogs were distributed in 4 groups: control group 1 (8 dogs - females), control group 2 (8 dogs - males), experimental group 1 (8 dogs - females) and experimental group 2 (8 dogs - males).
The investigation targeted the pH of skin and the rate of sebum’s secretion. The animals from the experimental groups were treated with Anabolin forte for 2 days at a dose of 1 mg/kg body weight/day, intramuscular.
The obtained results revealed that administration of Anabolin forte in males induced a significantly distinct intensification (with 10.66%) of sebum’s secretion and a significant decrease of pH of the skin (with 17.1%) compared to the animals from the control group. The administration of Anabolin forte in females induced a significantly distinct intensification (with 17.47%) of sebum’s secretion and a significant decrease of the pH of the skin (with 14.32%) compared to the animals from the control group.

Abstract

The aim of the study was to evaluate the effect of repeated low doses of GnRH agonist buserelin once a day for 5 days on follicle development and ovulation in anovulatory dairy cows with follicles growth only to emergence. The study was conducted on 71 anovulatory Polish Holstein Friesian cows. Anovulation with growth of follicles to emergence was defined as small ovaries with follicles of ≤ 5 mm in diameter and without corpus luteum on two examinations in a 7-10 day interval between 50-60 days after parturition. Cows were allocated to one of two group. Cows from group 1 (n = 58) received 0.4 μg of buserelin (Receptal, MSD, Poland) i.m. once a day for 5 days. Control cows from group 2 (n = 13) received saline. Ovarian structures were monitored weekly after the end of treatment by ultrasound for 4 weeks. The diameter of ovarian follicles on the ovaries was measured and recorded. Occurrence of ovulation was determined by the presence of corpus luteum. Overall, ovulation occurred in 46.6% (27/58) of cows treated with repeated doses of GnRH, while no corpus luteum was observed in the control group during the study period. There were significantly (p<0.05) more follicles 6-9 mm in diameter and 10-20 mm in diameter in cows treated with GnRH than in control cows. In conclusion, repeated low doses of GnRH analogue buserelin once a day for 5 days stimulate the development of ovarian follicles in anovulatory dairy cows with small ovarian follicles and led to ovulation in 46.6% of cows during 4 weeks after the end of the treatment.

Abstract

Helicobacter pullorum ( H. pullorum) is a bacterium that colonizes the intestines of poultry and causes gastroenteritis. Because these species are known as human and/or animal pathogens, identification of H. pullorum is becoming increasingly necessary. The bacterium has been linked to colitis and hepatitis in humans after being transmitted by infected meat consumption. Misdiagnosis of other enteric zoonotic pathogens such as Campylobacter and other Helicobacter species makes the diagnosis of H. pullorum extremely difficult. This study focused on the molecular detection of H. pullorum from the stomach (proventriculus and gizzard) of different avian species as new target organs for detection and transmission between avian species. Proventriculus and gizzards were obtained from 40 freshly dead chickens and resident wild birds (n=40). Diarrhea was found in the farms that were surveyed. DNA was extracted from all collected samples to conduct PCR amplification. The samples were screened for Helicobacter genus-specific 16s using C97 and C05 primers. To confirm the existence of H. pullorum, the positive samples were sequenced.
H. pullorum was recorded in two out of 40 chicken samples. In addition, H. pullorum was recorded in one out of 40 resident wild birds. The 16S rRNA gene sequence for Helicobacter genus-specific in poultry and wild birds showed a 100% homology. In conclusion, broiler chickens and resident wild birds are possible reservoirs for H. pullorum, according to this report, and possibly act as a source of infection for humans via the food supply.

Abstract

The equine infectious anaemia virus (EIAV) is one of the most serious equine diseases worldwide. There is scarce information on the epizootiology of equine infectious anaemia (EIA) in Saudi Arabia. Given the importance of the equine industry in Saudi Arabia, this cross- -sectional study aims to provide information about the prevalence of EIAV based on serological surveillance of the equine population in the country. A total of 4728 sera samples were collected (4523 horses and 205 donkeys) between December 2017 and November 2019. All samples were tested using commercially available EIAV ELISA. All tested samples showed negative results for EIAV antibodies with a 95% confidence interval. The results provided evidence that Saudi Arabia’s equine populations (horses and donkeys) are currently free of EIAV. The results also suggest the need for continuous monitoring of EIAV and strict regulation when importing horses from other countries.

Abstract

Brucella canis infection is one of the most important causes of infertility in dogs and is a zoonosis for which no effective treatment or vaccines exist. It is not a mandatory notifiable disease. Following an increase of cases in Europe and worldwide, an investigation was performed to evaluate how much Italian and Polish veterinarians and breeders know about canine brucellosis and understand their perceptions of this infection. For this reason, two questionnaires were prepared, in Italian and Polish. Eighteen Italian and Polish veterinarians, specialists in canine reproduction, responded to the first survey and 44.4% of them affirmed having diagnosed canine brucellosis at least once in their clinical practice, and different perceptions emerged regarding the infection in the two countries. The second survey was completed by 145 Italian and Polish breeders; the disease was completely unknown to 22.8% of them, whereas 2.1% had diagnosed infection by B. canis in their kennels. In conclusion, knowledge of B. canis infection differs between these countries, with extremes ranging from diagnosed cases to complete underestimation of the presence of the problem. However, based on international data and reporting of a recent large outbreak in Italy, awareness of this contagious infectious disease and its management must be increased.

Abstract

Videodermoscopic examinations have only recently started to be used in veterinary medicine and usually involve a small group of animals.
The aim of this study was to compare specific dermoscopic parameters in selected areas of the body of Arabian horses in the summer and winter seasons. The research was conducted between 2018-2019. The procedure was performed on the left side of the horse’s body in seven areas: head, neck, chest, flank, rump, mane, and tail. 42 purebred Arabian horses aged 1-25 (median), 39 mares and 3 stallions were qualified for the study. An Italian Video-Dermascope 7 (Medici Medical SRL with the 3 VIDIX 5Mpx camera and the VX1 overlay - Contact type cap Ø 3.5 cm) was used in the dermatoscopic evaluation. Specialist Cellsens Olympus software for analysing microscopic images was used to perform the measurements. Regardless of the area assessed, the skin in the summer months is darker than in the winter months. Hair thickness ranged from 44.82 (chest in summer) to 87.45 um (mane in winter). Regarding hair density, the number of hairs in the field of view of the dermatoscope ranged from 990 (summer mane) to 3680 (head in winter). Our research showed that the season of the year influences the amount of hair without significantly affecting its thickness.
