“…Hydatid cysts can occur in all organs and tissues of the body, especially the liver and lungs (Soulsby, 1982;Moro & Schantz, 2009). There also seems to be an association between hydatid cyst infections and bacteria at some localization sites (Aslam et al, 2005;Ziino et al, 2009) and some metacestode antigens can enter the circulation to induce an immune response (Turgay & Ü stü n, 2004). The severity of this reaction appears to be related the size and weight of the larval form known as the metacestode, which in turn results in the destruction of tissues within infected organs (Turgay & Ü stü n, 2004).…”

The aim of this study was to investigate the effect of hydatid cysts and microbial agents on the acute-phase response in cattle. Twenty-seven cattle with hydatid cysts and eight apparently healthy cattle comprised the study and control groups, respectively. Parasitological, microbiological, histopathological and immunohistochemical examinations of the liver and lungs were undertaken, and 49 of these organs were infected with cysts. In 14 of 31 (45.1%) livers and 10 of 18 (55.5%) lungs microbial growth was observed. The most frequent species occurring in the liver were Staphylococcus aureus, Escherichia coli, Corynebacterium spp. and Campylobacter spp., whereas in the lungs the most common species was Candida spp., followed by Streptococcus spp., Mannheimia haemolytica, Corynebacterium spp., Micrococcus spp. and S. aureus. The concentration of serum interleukin (IL-6) in infected cattle, 455.35 ± 39.68 pg/ml, was significantly higher than that of 83.02 ± 17.87 pg/ml in the control group (P0.05). The highest concentrations of IL-6 were detected in serum of the cattle where microbial growth had been detected, followed by cattle infected with bacteria + Trichostrongylus sp. (P< 0.001). Consequently, SAA showed an important increase in the group infected with hydatid cysts, whereas haptoglobin level decreased. It was noticed that IL-6, like SAA, had a significant role in hydatid cyst infection. Therefore IL-6 and SAA appear to be major markers in the detection of infection of cattle with hydatid cysts.

“…These holobionts have been most extensively studied in filarial and entomopathogenic nematodes, where a single bacterial species association occurs (Forst & Clarke, 2002; Taylor et al , 2005). Bacteria from other helminths have been studied less extensively, but are known to harbour a diverse range of species (Cable & Tinsley, 1992; Hughes-Stamm et al , 1999; Bakke et al , 2006; Ziino et al , 2009). In particular, intestinal helminths are known to host a rich bacterial community (Hsu et al , 1986; Krecek et al , 1987; Poddubnaya & Izvekova, 2005; Korneva, 2008; Hayes et al , 2010), and it would appear that the digestive tract is a major site for interactions between bacteria and these parasites.…”

Symbiotic bacteria of helminths: what role may they play in ecosystems under anthropogenic stress?

Symbiotic bacteria are a common feature of many animals, particularly invertebrates, from both aquatic and terrestrial habitats. These bacteria have increasingly been recognized as performing an important role in maintaining invertebrate health. Both ecto- and endoparasitic helminths have also been found to harbour a range of bacterial species which provide a similar function. The part symbiotic bacteria play in sustaining homeostasis of free-living invertebrates exposed to anthropogenic pressure (climate change, pollution), and the consequences to invertebrate populations when their symbionts succumb to poor environmental conditions, are increasingly important areas of research. Helminths are also susceptible to environmental stress and their symbiotic bacteria may be a key aspect of their responses to deteriorating conditions. This article summarizes the ecophysiological relationship helminths have with symbiotic bacteria and the role they play in maintaining a healthy parasite and the relevance of specific changes that occur in free-living invertebrate-bacteria interactions under anthropogenic pressure to helminths and their bacterial communities. It also discusses the importance of understanding the mechanistic sensitivity of helminth-bacteria relationships to environmental stress for comprehending the responses of parasites to challenging conditions.

“…1978). According to Boes and Helwigh (Boes and Helwigh 2000), there are two types of synergy between parasites and bacteria: rst, indirect synergy, that causes an increase in the pathogenic effects of the bacteria and makes the host susceptible to the bacterial disease, especially when the bacteria and parasites occur in the same tissue or organ; and secondly, a direct synergy that occurs when bacteria transported into the host by the parasite after invading stages of the parasite present in the environment (Ziino et al 2009).…”

“…According to certain views, the infection may have entered by the bile duct or enterohepatic circulation. Although only to a limited extent, hydatid cysts can be infected through the bronchial tree or a hematogenous pathway(Ahmed et al 2021;Wani et al 2010;Ziino et al 2009). The current study's ndings revealed that the plants studied have varying amounts of antibacterial activity.…”

Echinococcosis is a common and endemic disease that affects both humans and animals. In this study, the in vitro activities of methanolic extracts of Ruta graveolens, Peganum harmala aerial parts, and Citrullus colocynthis seeds against protoscolosis and isolated bacterial strains from hydatid cysts were assessed using disc diffusion methos and Minimum Inhibitory Concentration (MIC). The chemical composition of aerial sections of R. graveolensand P. harmala, as well as methanolic extracts of C. colocynthis seeds, was studied using LC-MS. These plants produced a total of 26, 31, and 23 chemicals, respectively. The bacteria listed below were isolated from hydatid cyst fluid collected from a variety of sick locations, including the lung and liver. Micrococcus spp., E. coli, Klebsiella oxytoca, Enterobacter aerogenes, Enterobacter amnigenus, Pseudomonas aeruginosa, Staphylococcus xylosus, and Achromobacter xylosoxidans are among the bacteria that have been identified. The most effective extract was R. graveolens, followed by P. harmala and C. colocynthis, according to the results of antibacterial activity using the disc diffusion method. R. graveolens extract had the lowest MIC values (less than 2 mg/mL) against all microorganisms tested. This shows that the R. graveolens extract has additional properties, such as the ability to be both scolocidal and bactericidal. Because these bacteria are among the most prevalent pathogenic bacteria that increase the risk of secondary infection during hydatid cysts, the results of inhibitory zones and MICs of the R. graveolens methanol extract are considered highly promising.
