Feasibility of near-infrared reflectance spectroscopy for predicting amino acids composition in edible bird’s nest
2016
Suhaimi D. | Wan Syahidah H. | Sharif S. | Normah Miw A.
A preliminary study of nearinfraredreflectance spectroscopy (NIRS)for the feasibility of analytical monitoring ofamino acids and total protein compositionsin edible bird’s nest (EBN) was conducted.The training (n=134) and validation sets todevelop the equations were built with localunprocessed EBN samples sourced fromdifferent states of Malaysia. The regressionmethod employed was modified partialleast-squares (MPLS). The values ofstandard error for cross validation (SECV)and the coefficient of determination (r2)of the calibrations of these constituentsfor use to predict of amino acids in EBNwere determined, but with a low predictiveability. To find an acceptable accuracyfor each constituent is to increase thenumber of training samples. The findings,however, showed a potential alternativefor the implementation of near-infraredreflectance spectroscopy technology inthis field of analysis.

Colibacillosis is animportant disease affecting the poultryindustry in many countries, caused bythe Avian Pathogenic E. coli (APEC):it manifests as various clinical signs. Itcontributes significantly to economicloss for poultry farmers as a result ofhigh mortality and morbidity in poultry.To overcome this, antibiotics have beenwidely used to eliminate E. coli infectionin poultry farms in recent years. Treatmentwith antibiotics has been considered as avital regimen to control E. coli infectionat the farm level for many years. However,high frequency of antibiotic resistance ofE. coli isolates from chicken has becomethe centre of attention due to public healthimportance. The aim of the present study isto determine the multidrug resistant profilesof E. coli strains isolated from chicken.E. coli isolates obtained from clinicalcases were re-identified and classified byconventional methods. Multidrug resistantprofiles against 13 different antibiotics of125 E. coli isolates were determined byusing disk diffusion method accordingto Clinical Laboratory Standard Institute(CLSI). Antibiogram revealed that 81.6%of the E. coli isolates showed multidrugresistant profiles to different antibiotics.Most of the E.coli isolates were highlyresistant to erythromycin (52.8%), followedwith tetracycline (52.0%), spectinomycin(39.2%), trimethoprim (38.4%) andflumequin (37.6%). Out of 125 isolatestested, 19.2% were resistant to more thaneight antibiotics, with one isolates found tobe multidrug resistant to most of antibioticsexcept polymyxin B. These findings alsodemonstrated that most of the isolateswere susceptible to antibiotics commonlyused for E.coli infections treatment inpoultry with lowest resistant score againstpolymyxin B (92.8%) and colistin (92.0%).Moderate resistant profiles were observedtowards amoxycilin (25.6%), apramycin(16%), kanamycin (8.8%) and streptomycin(8.0%). High percentage of multidrugresistance was found among the E. coliisolated from chicken as an indicator tomore serious problems in animal health.Therefore, continuous surveillance of antibiotic resistance profiles in chicken andother food animals is crucial to ensure foodchain safety
Afficher plus [+] Moins [-]An overview of vitamin C as an antistress in poultry
2016
Mohammed, A. A. | Ahmadu, S. | Buhari, H. | Auwal, A.
Stress is commonly used to describe the detrimental effectsof a variety of conditions surrounding animals on their health performance. Environmental stress causes an increasein oxidative stress and an imbalance in antioxidant status. Oxidative damage increases in stressed poultry when the plasma antioxidant vitamins and minerals such as vitamin C, E, folic acid, and zinclevels declined. Stress factors in birds involve many elements of the transport processes which may be detrimental to the birds. These factors include alteration in atmospheric temperature, poor handlingby man, removal of feed and water (starvation), high ambient temperature (AT) and relative humidity (RH). Other factors incude vaccination, disease conditions such as coccidiosis, novelty,confinement, motion, noise, microthermal core within the vehicle and the use of inappropriate vehicles. Live birds of all ages are being transported mainly by roads to their various destinations and across different ecological zones throughout the year. Mortality increaseswith journey length. The adverse effects of these factors and their combinations may range from mild discomfort and aversion to death. This review was aimed at providing comprehensive information on the role of vitamin C in combating stress factors in poultry with the view of exploring its potentials for future research undertaking.Information compiled in this review were obtained from search engines such as Elsevier, Pubmed, Springer, Medline, Science Direct, Google Scholar, and a library search for articles published in peerreviewedjournals. 100 to 200 mg/kg feed of vitamin C is capable of converting stress factors in poultry and thereby improving the productivity.

The objectives of the present study were to determine the infection rate of equine piroplasmosis (EP) in horses and ponies in Kelantan,Malaysia and compare the microscopic examination with competitive enzymelinked immunosorbent assay (cELISA) test as methods for diagnosis of EP. 306 blood samples were randomly collected from equids including 148 horses and 158 ponies in various districts of Kelantan, from September 2013 to March 2014. Based on microscopic examination of the staining blood smears, the infection rates ofTheileria equi, Babesia caballi and of both infections in horses were 19.59%, 25% and 8.78% respectively, whereas in ponies theinfection rates were 14.55%, 19.62%, and 5.69% respectively. Based on cELISA test, the infection rates of T. equi, B. caballi and of both infections in horses were 50.67%, 62.16% and 33.10% respectively,whereas in ponies, the infection rates were 51.89%, 63.92% and 35.44% respectively. No significant difference were observed between equids species associated with a seroprevalence of T. equi, B. caballi andof both infections (P≤ 0.05). According to the Kappa value there was no compatibility between microscopic examination and cELISA on the diagnosis of T. equi, B. caballi and of both infections which were 0.235, 0.013 and 0.080 respectively. In conclusion, the current results for this research work indicate that equine piroplasmosis is widespread in Kelantan, Malaysia and cELISA test is more efficientthan microscopic examination for diagnosis of EP.

Toxoplasma gondii is a protozoan parasite that causes toxoplasmosis in humans and animals. It belongs to the phylum Apicomplexa, subclass Coccidiasina and family Sarcocystidae. The Felidae family is thedefinitive host for this disease where the parasites undergo a sexual cycle of replication (oocysts). In this study, cat faeces were collected from private clinics around Johore Bahru, Peninsular Malaysia. A total of 61 samples were tested using microscopy to detect for presence of T. gondii oocyst via two methods; namelythe Modified Kato-Katz with Kinyoun staining and Sheather’s sugar floatation methods. The results showed that 40.98% of the faecal samples tested were positive for T. gondii oocysts. These two methodswere successfully used in diagnosing toxoplasmosis in cats in this study. Morphological approaches for Toxoplasma oocysts identification have been neglected in recent years, due to the upsurge of moreprecise technologies. This study suggests that this modified technique could be introduced for screening and detection of oocysts excreted in faeces of suspected animals of the Felidae family.

Rosilawati K. | Nurul Faizah Z. | Saipul Bahari A. R.
This study was conducted to investigate the high mortality of young lambs in two sheep farms in Pekan, Pahang over a period of 3 years. Samples from postmortem of 1,451 lambs below one year of age by a farm veterinarian were submitted for laboratory diagnosis at the Bacteriology Section of the Regional Veterinary Diagnostic Laboratory in Kuantan. Escherichia coli is the most commonly recorded bacteria with 161 lambs diagnosed in 2013. In 2014 and 2015, there was a decrease in occurrence of E. coli related deaths, with 120 and 75lambs respectively. A total of 25% of the cases showed Escherichia coli positive by culture on blood agar and MacConkey agar, and confirmed by biochemical tests. A total of 21% of the cases were positive for staphylococcus sp, 3% and 6% for Streptococcus sp and Klebsiella pneumonia, respectively. Other bacteria were isolated in 45% of the cases. It was further noted that a total of 285 lambs between the ages of one to four months of age followed by 58 lambs (20%) less than one month old had E.coli isolation. It is also noteworthy that there were 10 lambs with E.coli infection in one to fourteen day-old lambs during the 3-year period from January 2013 to December 2015. This information was collated as a result of routine diagnosis of field cases submitted and with the intention of highlighting the common pathogens causing high mortality in local small ruminant farms so that preventive action may be taken for future farming ventures. E. coli infections or Colibacillosis is an important finding and indicator of poor management including poor nutrition, hygiene and environmental contamination which can reduce animal immunity and render it susceptible to other infections.

Corynebacterium pseudotuberculosis is the causative agent of caseous lymphadenitis (CLA) a contagious and infectious disease in smallruminants. This report describes a case of CLA in a Boer cross goat infected with Corynebacterium pseudotuberculosis. The manifestation of abscess in the superficial lymph node presented as a mass ofapproximately 5 cm by 5 cm in diameter at the base of the ear. The mass was solid and non-movable upon palpation. The mass was incised and the caseous material was aspirated and sent to the bacteriologylaboratory where Corynebacterium pseudotuberculosis was isolated. Thewound was cleaned and flushed with diluted chlorhexidine and iodine solutions daily. This procedure aids in the complete healing of the wound after a few weeks. However, the agent of the disease persistsin the animal in its entire life and culling is recommended to prevent the spread of the disease in the herd.

Peste des petits ruminants, caused by the peste des petits ruminants virus (PPRV), is a highly contagious and economically important transboundary viral disease of domestic and wild small ruminants and a major hindrance to small-ruminant production in Nigeria. The seroprevalence and distribution of PPRV antibodies in small ruminants in rural households, farms, live animal markets and slaughter slabs across the six different agro-ecological zones of Nigeria were determined. A total of 4548 serum samples from 3489 goats and 1059 sheep were collected in 12 states. A PPRV competitive enzyme-linked immunosorbent assay was used to test the samples and the data analysed with R statistical software version 3.0.1. The study animals included all ages and both sexes. The overall prevalence estimate of sera positive for PPRV antibodies was 23.16% (n = 1018 positive samples per 4548 total samples, 95% confidence interval: 21.79% - 24.57%). There were significant differences in the seroprevalence between the states (p = 0.001). Taraba State had the highest seroprevalence of 29.51%, whilst the lowest seroprevalence of 14.52% was observed in Cross River State. There were no significant differences in the PPRV seroprevalence between male and female animals (p = 0.571), age (p = 0.323) and between species (p = 0.639). These data indicate the current seroprevalence to PPRV in the small-ruminant population in Nigeria.
