2023
Sayed Ahmad Nourbakhsh | Ebrahim Rahimi
Objective: Arcobacter butzleri, Listeria monocytogenes, Staphylococcus aureus, and Campylobacter jejuni are significant foodborne pathogens regarding the consumption of raw poultry meat. An existing survey was conducted to assess the occurrence of S. aureus, C. jejuni, A. butzleri, and L. monocytogenes in raw poultry meat samples. Materials and Methods: Ninety-four raw ostrich, turkey, chicken, and quail meat samples were collected and subjected to culture-based analysis. Staphylococcus aureus, C. jejuni, A. butzleri, and L. monocytogenes isolates were confirmed by standard biochemical techniques. Results: The occurrence of A. butzleri, C. jejuni, L. monocytogenes, and S. aureus in poultry meat samples was 11.45%, 17.70%, 1.04%, and 16.66%, respectively. L. monocytogenes was absent in chicken, turkey, and ostrich meat samples. Only one quail meat (4.16%) was positive for L. monocytogenes. The uppermost contamination rate with A. butzleri, C. jejuni, and S. aureus was found in chicken (25%), turkey (25%), and turkey (25%) meat samples, respectively. The concur¬rent occurrence of A. butzleri + C. jejuni + S. aureus bacteria amid the examined poultry meat samples was 2.08%. Conclusion: This is an initial report of A. butzleri, S. aureus, C. jejuni, and L. monocytogenes in poultry meat samples. Adequate cooking of poultry meat can diminish foodborne diseases due to A. butzleri, S. aureus, L. monocytogenes, and C. jejuni bacteria, and these species may constitute a public health problem.

De Roest, Kees | Molenaar, R. | Malchow, J. | Schrader, Lars | Bučková, Katarina | Niczyporuk, Jowita | Kozdrun, Wojciech | Tomczyk, Grzegorz | Thomas, Johan | Papasolomontos, Sotiris | Kefalas, George | Simitopoulou, Maro | Angastiniotis, Kyriacos
Many pig and broiler farmers struggle to reduce the use of antimicrobials on their farms. The improvement of the level of biosecurity certainly is one of the most effective ways to prevent pathogens entering the farm. Research is focused however also on other strategies, which may reduce the reliance on antimicrobials: increase animals’ resilience, early detection of diseases and targeted use of antimicrobials. These three strategies may exert a long term effect on the necessity tofight animal diseases. Several innovations are being tested that belong to these strategies, but most of these techniques have not yet been applied at farm scale In this paper a first analysis has been carried out to estimate the costs and benefits of innovations to improve resilience, to early detect diseases and to implement a targeted use of antimicrobials. As most of the innovations have been tested in experimental settings, the results of the economic analysis still have be treated with care. It provides however a first assessment of the economic convenience of the innovations and a list of key performance indicators that need to be taken into account in the analysis. For this analysis the partial budgeting approach has been used. Where broilers are concerned the analysis has been centred on on-farm hatching, elevated platforms, use of probiotics, automatic weighing systems and targeted use of non-antimicrobial feed and/or water additives. For pigs the analysis has been focused on innovative enrichment material to improve pig welfare and video-surveillance systems to early detect diseases.

This study aims to determine the histomorphometry of the small intestine of turkeys (Meleagris gallopavo) at different age levels. This study used a completely randomized design. This study used 18 male turkeys, divided into 3 groups of ages 8, 16, and 24 weeks, each group comprising 6 turkeys. The necropsied turkey's small intestine was taken into histological preparations and stained with haematoxylin-eosin (HE). The results showed that the histological picture of the small intestine layer of turkeys at different age levels consisted of four layers: tunica mucosa, tunica submucosa, tunica muscular, and tunica serosa. Histomorphometrically, there was an increase in the thickness of all layers of the small intestine from 8 and 16 weeks of age (P0.05), and the height of the intestinal villi increased in all parts of the small intestine at 8, 16 and 24 weeks of age (P0.05 ). In conclusion, with histomorphometric measurements, it can be seen that there are differences in the three age groups.

One of the fishery products that decomposes very rapidly is shrimp. Utilizing natural preservatives, such as Averrhoa bilimbi L. juice, is one method for maintaining the quality of food ingredients. This study aims to determine the effect of adding A. bilimbi L. juice with different concentrations and soaking times on vannamei shrimp decay. In this study, an experimental laboratory was used to examine decay using the Postma and H2S tests. As much as 500 g of vannamei shrimp were divided into four treatment groups and two repetitions, with 5 g of each sample soaked in A. bilimbi L. juice with concentrations of 0%, 2.5%, 5%, 7.5%, and 10% for 0, 3, 6, and 9 hours. Early decay was observed at 0 and 3 hours after soaking vannamei shrimp in solutions with concentrations of 0%, 2.5%, 5%, 7.5%, and 10%. At concentrations of 5%, 7.5%, and 10%, there was no initial decay after soaking vannamei shrimp for six hours at a concentration of 0% and 2.5%. During 9 hours of soaking at concentrations of 0%, 2.5%, and 5%, initial decay occurred, whereas there was no initial decay at concentrations of 7.5% and 10%. The conclusion of this research is A. bilimbi L. juice with concentrations of 7.5% and 10% for 6 and 9 hours inhibits the decomposition of vannamei shrimp.

The impact of free radicals on testicular Leydig cells can result in the disruption of male reproductive health. The present study aimed to evaluate the effects of a high-fat diet on Leydig cells and the potential of kepok banana peel extract as a medication to mitigate these effects. In total of 20 adult male Wistar rats were assigned to five groups and treated with standard feed (P1), high-fat feed (P2), high-fat feed with simvastatin (P3), and high-fat feed with banana peel extract at doses of 100 and 200 mg/kg BW (P4 and P5). After 60 days of treatment, the number of Leydig cells was determined using HE staining methods. Data were analyzed using an One Way ANOVA test. The results showed that the administration of 100 mg/kg BW of kepok banana peel extract (P4) was able to maintain the number of Leydig cells and counteract the negative effects of a high-fat diet. These findings suggest that kepok banana peel extract may have the potential as a herbal medicine for supporting male reproductive health.

Blood is a good growth medium for bacteria by preventing the accumulation of toxic oxygen (peroxide and superoxide) and increasing the growth ability of these bacteria. The purpose of this study was to evaluate the ability of lysed sheep blood and lysed cow blood as a substitute for lysed horse blood on Campylobacter growth media, as well as evaluate the growth of Campylobacter from chicken meat samples on culture media supplemented with lysed sheep blood and lysed cow blood compared to the media cultures using lysed horse blood supplements. The concentration of lysed sheep blood, lysed cow blood, and lysed horse blood used was 5% each. The chicken meat samples used in this study were 30 samples. Based on the results, 14 samples of C. jejuni bacteria showed the ability to grow up to 107 and 16 samples up to 106. In the media added with lysed cow blood supplement only one sample was able to grow up to 106, 17 samples grew up to 105, and 12 samples grew up to 104. These results statistically used the one way analysis of variance (ANOVA) test indicating a significant difference significant (P0.05). Further tests using post hoc least significance different (LSD) showed a comparison of the average growth in lysed horse blood, lysed sheep blood, and lysed cow blood significantly different (P 0.05), while the average value of each treatment was the addition of lysed horse blood supplements, lysed sheep blood, and cow blood consecutive lysis was 8.551 ± 0.340, 7.117 ± 0.544, and 5.265 ± 0.548. The addition of lysed sheep blood and lysed cow blood to bolton broth media in this study can be used for C. jejuni isolation. However, the blood of lysed sheep had a higher effectiveness in the ability to grow C. jejuni, which was close to the ability to grow with the addition of lysed horse blood as a control, compared to the addition of lysed cow blood.

A cross-sectional study was conducted from December, 2019 to May, 2020 with the aim of determining seroprevalence and identifying the potential risk factors of brucellosis in dairy cows with recent cases of abortion and their owners and farm workers in selected sites in the central highland of Oromia, Ethiopia. The overall seroprevalence of bovine and human brucellosis was 0.61% (95%CI: 0.016–2.09) and 1.21% (95%CI: 0.032–4.27) using combined RBPT and CFT tests, respectively. The late stage of abortion (OR = 14.74, p =0.0002), retained fetal membrane (OR = 32.74, p=0.006), market-based stock replacement (OR = 16.55, p=0.002), and presence of parturition pen (OR = 11.511, p=0.027) were found to be significantly associated with seropositivity for Brucella infection in dairy cattle. Human housing (OR = 1.8, p = 0.002), contact with aborted fetus (OR = 21.19, p = 0.017), and drinking raw milk from aborted (OR = 5.72, 0.019) and retained fetal membrane (OR = 4.22, p= 0.029) cows all had a significant influence on human brucellosis seropositivity. A structured interview question was administered to 284 respondents. Accordingly, most respondents had no knowledge of bovine brucellosis and their zoonotic effects (93.3%) in contrast most of them drink raw milk. Implementation of a test and slaughter strategy with compensation is recommended with this low prevalence. In the case of human brucellosis, implementing one health approach framework should be practiced.

Goncalves, Juliano L. | Freu, Gustavo | Garcia, Breno L.N. | Barcelos, Melina M. | Alves, Bruna G. | de Freitas Leite, Renata | Pedrosa Monteiro, Camylla | Martins, M. | Tomazi, Tiago | Hogeveen, Henk | Veiga dos Santos, Marcos
This review summarized the significant results from Brazilian studies published in peer-reviewed scientific papers about the effect of bovine subclinical mastitis (SM) on economic performance and milk production. Different approaches were considered for (i) disease detection (indirect measurement of somatic cell count (SCC) and directly using microbiological culture) and (ii) milk sampling strategy (mammary quarters, composite cow samples, and bulk milk tank). Globally, bovine mastitis is the most common disease of dairy herds, and the subclinical presentation is the most frequent. Dairy farmers usually underestimate the economic losses associated with SM because no visual changes in milk and quarters, udder, and systemic symptoms are observed. SM reduces milk yield and quality, reducing dairy herds’ profitability. The estimation of losses depends on the causative pathogen, the lactation stage, and the parity of affected cows. Thus, estimating the economic caused by SM in milk production and economic performance in dairy herds can be used to decide which mastitis control strategies to adopt. Mastitis control involves adopting specific measures associated with the characteristics of each herd, the period of the highest frequency of cases, the transmission form, and the profile of the pathogens involved in cases of intramammary infection. Thus, using individual SCC, the microbiological identification of pathogens causing SM, adopting efficient drying-off protocols, and other management practices are essential for mastitis control, improved milk quality, and greater profitability of dairy herds.

The presence of Shiga toxin-producing Escherichia coli (STEC) and resistance to beta-lactams in healthy sheep represents a potential public health risk. This study aimed to characterize STEC isolates in sheep feces for toxin production and resistance to beta lactam antibiotics. In the present study, among the 40 isolates, we found a predominance of subtype Stx1 (22/40), followed by subtype Stx1 + Stx2 (11/40), while the less prevalent group was Stx2 (7/40). Also, we found phenotypical resistance to beta-lactam antibiotics in 50% (20/40) of the strains analyzed, forming two groups, one with resistant isolates and the other with non-resistant isolates. The cytotoxicity of the isolates did not vary among the groups. In addition to having this characteristic, some multiresistant isolates produced significant amounts of toxins. This leads to the conclusion that the mechanisms of antimicrobial resistance via beta lactamases are present in sheep STEC and that the cytotoxicity of those isolates is variable regarding such resistance.
