ABSTRACT

Background and Aim: Fascioliasis is a zoonotic disease of public importance that affects animals and man. This study was aimed at assessing Fasciola infection among goats slaughtered in Port Harcourt metropolis.

Materials and Methods: A total of 323 gallbladder and fecal samples were collected from three different abattoirs (Mile 3, Rumuokwurusi, and Trans-Amadi) between September 2015 and June 2016 and analyzed using standard parasitological method.

Results: Of the 323 fecal samples, 20 (6.19%) were found to be positive for Fasciola egg. Mile 3 abattoir 17 (5.26%) had higher prevalence than Trans-Amadi abattoir 3 (0.93%) while Rumuokwurusi had no infection (Chi-square=0.11; p=0.001). Gallbladder infection was 5.57%. Trans-Amadi abattoir had the highest prevalence of 11 (3.41%) followed by Mile 3 abattoir 7 (2.17%) and Rumuokwurusi abattoir had none (Chi-square=0.91; p=0.339). Infection based on gender showed that 5.88% of female animals and 0.31% of males were ova positive. At Trans-Amadi, 0.93% of females against 0.0% of males were infected (p>0.05). At Mile 3, it was 4.95% of females against 0.31% of males (p=0.001). Rumuokwurusi abattoir had no infection. Gallbladder infection showed Trans-Amadi 2.79% of females and 0.62% of males; Mile 3, 2.17% of females and 0.0% of males and Rumuokwurusi had no infection.

Conclusion: Fasciola infection is prevalent in goats in Port Harcourt. The health implication of these findings is that humans are at risk as fascioliasis is a zoonotic disease. There is a need to intensify effort to create more awareness of the possible consequence of this infection.

Keywords: fascioliasis, goats, infection, Nigeria, prevalence, zoonotic disease.

ABSTRACT

Aim: This study aimed to investigate the prevalence and implication of extended-spectrum beta-lactamase (ESBL) producing and Class 1 integrons (int1) gene carriers Escherichia coli isolates that demonstrated multidrug resistance (MDR) phenotypes and was isolated from turkeys that suffered from respiratory manifestation.

Materials and Methods: A total of 120 freshly dead turkey poults that suffered from respiratory manifestations, with a history of treatment failure at Hefna, Belbis, Sharqia (Egypt) were sampled. From each bird lung and liver were aseptically collected and transported for laboratory investigations.

Results: Examination of samples collected from 120 freshly dead turkey poults revealed the isolation of coagulase-positive staphylococci, coagulase-negative staphylococci, Campylobacter spp., Salmonella spp., Proteusspp., Pseudomonas spp., Klebsiella spp., and E. coli with the prevalence rates of 12/120 (10%), 30/120 (35%), 17/120 (14.2%), 5/120 (4.1%), 17/120 (14.2%), 6/120 (5%), 7/120 (5.8%), and 18/120 (15%), respectively. E. coliisolates were subjected for serotyping and characterization, while the rest of isolates were preserved to be investigated later in further studies. Serogrouping of E. coli isolates revealed the identification of O119, O6, O8, and O169, while 1/18 isolate was untypable. Studying phenotypic antibiotic susceptibility profiles of isolates revealed that 18/18 (100%) of isolates demonstrated resistance against cefuroxime, tetracycline, and trimethoprim, 16/18 (88.9%) of isolates demonstrated resistance to amoxicillin/ clavulanic acid, enrofloxacin, and norfloxacin, 14/18 (77.8%) of isolates demonstrated resistance to doxycycline and ciprofloxacin, and 9/18 (50%) of isolates showed resistance to gentamycin. Double disk synergy test showed that 6/18 (33.3%), 8/18 (44.4%), and 13/18 (72.2%) of isolates demonstrated the phenotypic pattern of ESBL producers with cefepime, cefotaxime, and ceftriaxone, respectively. Genotypic attributes for beta-lactamase TEM gene and int1 gene were studied by reverse transcriptase-polymerase chain reaction and revealed that 17/18 (94.4%) of isolates were positive for both genes. Embryo lethality test indicated that the 18 studied E. coli isolates were considered primary pathogens.

Conclusion: The results revealed that 18/18 (100%) of E. coli isolates demonstrated MDR against three or more antibiotic groups, 9/18 (50%) of isolates showed extensive resistance against the nine tested chemotherapeutic agents from seven antibiotic groups. It is recommended to monitor the circulation of MDR and ESBL-producing pathogens in poultry production in a one health approach, as a preventive measure to mitigate the risk imposed on public health.

ABSTRACT

Aim: The study aimed to identify fatty acid synthase (FASN), LOC514211, and fat mass and obesity-associated (FTO) gene polymorphisms and to investigate their associations with milk traits in an Indonesian-Holstein dairy cow population.

Materials and Methods: A total of 100 Indonesian-Holstein cows consisting of 50 heads (0th generation; G0) and 50 heads of their daughters (1st generation; G1) were used. Polymerase chain reaction-restriction fragment length polymorphism was performed to genotype three single nucleotide polymorphisms: rs41919985 in the FASN gene, rs42688595 in the LOC514211 gene, and g.1371T>A in the FTO gene.

Results: FASN rs41919985 was associated with milk protein percentage (p<0 .05="" fto="" g.1371t="">A was associated with milk fat percentage (p<0 .05="" and="" any="" associated="" loc514211="" not="" p="" rs42688595="" trait="" was="" with="">0.05). Heterozygote variants showed a higher protein percentage for FASN and the highest fat percentage for FTO. These associations were consistent in the G0 and G1 populations.

Conclusion: Our results indicate that the milk protein and fat percentages can be improved by increasing the frequency of the AG genotype of FASN and the AT genotype of FTO, respectively.

ABSTRACT

Background and Aim: Dairy animals play an important role in the Indian economy. Knowledge of the occurrence pattern of long bone fractures in bovine may help in strategizing the possibilities of treatment and prognosis. This study aimed to find out the comparative occurrence pattern of fractures in cattle and buffaloes.

Materials and Methods: A total of 278 fractures of bovine (171 in cattle and 107 in buffaloes), presented to the Department of Veterinary Surgery and Radiology, Guru Angad Dev Veterinary and Animal Sciences University, Ludhiana, Punjab, India, during a study of 1 year, were investigated for the occurrence pattern, in relation to species, age, body weight, gender, bone involved, type of fracture (closed or open), and the presentation of bovine as standing or in recumbent state.

Results: The overall hospital occurrence of fractures in bovine was 4.24% and most of the fractures resulted from slipping and falling on hard floor. Of 278 fractures, the majority (90.28%) involved long bones (n=251; 103 buffaloes and 148 cattle). Forelimb fractures were recorded more common in buffaloes (64.08%), whereas the cattle suffered more of hind limb fractures (60.23%). Cattle also included 11 cases of bilateral fractures of metacarpal (n=3), tibia (n=1), radius and ulna (n=1), and mandible (n=6). Fracture of olecranon constituted 6.83% (n=19) and majority (n=15) were in buffaloes. The cattle had higher percent of open fractures (54.38%) as compared to that in buffaloes (17.76%). Marginally higher percentage of cattle (33.33%) suffering from fracture were recumbent as compared to buffaloes (23.36%) and femur fractures were found to be a leading cause of recumbency (100% in cattle and 75.00% in buffaloes).

Conclusion: Species-specific differences in the occurrence pattern of fractures exist among cattle and buffaloes. Cattle are found to be more susceptible (1.5 times) to fractures as compared to buffaloes. The buffaloes are vulnerable to forelimb fractures while the cattle to the hind limb. As compared to forelimb, long bone fractures of hind limb are more commonly associated with recumbency in bovine. Cattle are more prone to mandible fractures and the open fractures of long bones as compared to buffaloes.

ABSTRACT

Background and Aim: Despite the importance of the global emergence of Vibrio parahaemolyticus infections worldwide, there has been scanty information on its occurrence in Malaysian seawaters and fish. This study aimed to determine the occurrence of V. parahaemolyticus isolates using polymerase chain reaction targeted at toxin operon gene, thermostable direct hemolysin (tdh), and tdh-related hemolysin genes and to determine antibiotic resistance pattern, genes, and plasmid profile of V. parahaemolyticus from Malaysian seawaters and fish.

Materials and Methods: Samples were collected from four recreational beaches in Malaysia (Port Klang; Bachok; Port Dickson; and Mersing). Thiosulfate-citrate-bile salts-sucrose (TCBS) agar and chromogenic Vibrio agar were used for isolation and identification. Colonies with yellow color on TCBS and green color on chromogenic vibrio (CV) agar were considered to be V. parahaemolyticus and they were subjected to biochemical tests. All V. parahaemolyticus isolates were further subjected to identification using seven specific gene markers.

Results: Seventy-three Vibrio isolates were recovered. Only one gene tdh> from seawater isolates of Vibrio has high virulence gene percentage (95.23%). Two genes alkaline serine protease (asp) and (tdh) had high percentage of virulence (83.87% and 80.64%, respectively) from fish. Comparatively, fish isolates have a higher virulence percentage compared to seawater isolates. Only gene streptomycin resistance B (strB) from seawater had 100% of the resistance genes. All isolates were multi-antibiotic resistant. Seventeen antibiotic resistance patterns were observed. The isolates had plasmids of varying sizes ranging from 2.7 kb to 42.4 kb. Dendrogram based on antibiotic resistance patterns of V. parahaemolyticus isolates discriminated the isolates into three clusters.

Conclusion: This study demonstrated the occurrence of pathogenic, multi-antibiotic-resistant V. parahaemolyticus strains in Malaysian coastal waters and fish, and this could constitute potential public health risks.

Keywords: antibiotic resistance genes, plasmid profile, Vibrio parahaemolyticus, virulence genes.

ABSTRACT

Background and Aim: The Barb horse occupies a prominent place in the history, culture, and equestrian traditions of the Maghreb (Algeria, Morocco, and Tunisia). Although many studies on the breed standard and morphometry have been published, there are no studies on its fertility and reproductive potential. Thus, this work aimed to study the fertility of Barb, Arabian Purebred, and Thoroughbred horses in Algeria.

Materials and Methods: A total of 168 stallions and 1202 mares at the Chaouchaoua Stud farm in Tiaret, Algeria, were included in the study. The reproductive performance during 1592 cycles over 10 consecutive mating seasons (2003-2012) was evaluated. Multivariate analysis with logistic regression was used to analyze the reproductive parameters such as the number of cycles operated, number of pregnant mares, pregnancy rate per cycle, seasonal pregnancy rate, and embryonic mortality rate, and to determine the influence of breed, stallion's age, and year of the study on reproduction.

Results: Statistical analysis showed that stallion breed was a significant influencing factor for the number of pregnant barren mares (Odds ratio [OR]=1.72; p=0.03; 95% confidence interval [CI]=1.05, 2.84) seasonal pregnancy rate (OR=1.40; p<0 .001="" 1.53="" 95="" additionally="" age="" barb="" ci="1.29," influence="" of="" performance="" regard="" reproductive="" s="" significant="" stallion.="" stallion="" superior="" that="" the="" thoroughbred="" to="" was="" with="">5 years on the number of pregnant foaling mares and seasonal pregnancy rate, significant interactions were observed between the stallion's breed and age, and the pregnancy rate per cycle: in the Barb breed, the pregnancy rate per cycle increased with the age of the stallion, while in the Thoroughbred, it decreased with age. Moreover, a significant effect of the year of the study on the pregnancy rate per cycle and number of pregnant foaling mares was observed. In contrast, the number of cycles and embryonic mortality rate were not influenced by the breed and age of the stallion, or the year of the study.

Conclusion: The Algerian Barb horse attained a similar level of fertility compared with that of the Arabian Purebred and Thoroughbred stallions depending on its age and reproductive performance.
