“…Although 84% and 76% positivity rates have been found in Finland in autumn and in spring, respectively [ 43 ], some studies have highlighted an increased incidence of Campylobacter detection in chicken and pig samples at slaughterhouses in relation to increased environmental temperature [ 56 ] and increased temperature and drought on broiler farms [ 57 ]. As a result, foodborne diseases, including campylobacteriosis, occur more frequently in warmer months [ 58 ]. The higher incidence of infection in farms during summer may also be influenced by the presence of flies [ 59 ], which may carry the germ within and between flocks [ 60 ].…”

Campylobacter (C.) jejuni and C. coli are responsible for food poisoning in humans. Laying hens may host the bacteria usually without developing symptoms. The aims of this paper were to evaluate the incidence of C. jejuni and C. coli infection in laying hen flocks housed in different rearing systems, the plasma levels of two welfare indicators (corticosterone and interleukin 6, IL-6) and the antimicrobial resistance of the detected Campylobacter strains. Two different flocks (1 and 2) from cage (A), barn (B) and aviary (C) farms were investigated. The highest (p < 0.05) levels of IL-6 were detected in laying hens housed in aviaries. A similar trend emerged in corticosterone level, although differences were found between C1 and C2. C. jejuni and C. coli were identified in 43.5% and 38.9% of birds, respectively. In total, 14 out of 177 (7.9%) hens simultaneously hosted C. jejuni and C. coli.C. jejuni was prevalently detected in hens housed in barns (B1: 53.3%; B2: 46.7%) and aviaries (C1: 34.6%; C2: 86.7%). Conversely, laying hens housed in cages were significantly exposed to infection of C. coli (A1: 41.9%; A2: 80%) while, regarding barns and aviaries, a significant prevalence emerged only in flocks B2 (40%) and C1 (54.8%). Simultaneous infection was statistically significant in barn B1 (36.7%). Antibiotic resistance was mainly detected among C. coli strains, and it was most frequent for fluoroquinolones and tetracycline. Multidrug resistance was also found in C. jejuni (19.7%) and C. coli (17.5%) strains. Based on the results of this study, we recommend increasing biosecurity and hygienic measures to manage hen flocks.

“…In addition, other authors indicated that climatic factors such as ambient temperature, rainfall, and relative humidity affect the incidence of these microorganisms. Hence, the rates of diseases could be influenced by climate change (Park et al 2018;Oh et al 2021).…”

The inactivation processes of coliform bacteria (total and fecal) and sulphito-reducing Clostridium bacteria (vegetative species and spores) in water maturation lagoon of a low-cost nature-based wastewater treatment plant using constructed wetlands and through processes of photolysis in a pilot photoreactor have been comparatively studied. The different inactivation mechanisms by photolysis of these bacteria have been studied following the criteria of different statistical and kinetic models. Clostridium disinfection treatments fit models in which two types of bacteria populations coexist, one sensitive (vegetative species) and the other (spores) resistant to the treatment, the sensitive one (94%) with an inactivation rate of k = 0.24 ± 0.07 min−1 and the resistant one (6%) with k = 0.11 ± 0.05 min−1. Total coliform photolytic disinfection also shows two populations with different physiological state. The time required to reduce the first logarithmic decimal cycle of the different types of bacteria (physiological states) are δ1 = 4.2 ± 0.9 and δ2 = 8.3 ± 1.1 min, respectively. For fecal coliform photolytic disinfection, only bacteria population, with k = 1.15 ± 0.19 min−1, is found. The results obtained confirm the photolytic disinfection processes and maturation lagoon are effective systems for Clostridia bacteria removal after water treatment by nature-based systems. Total removal of coliform bacteria is not achieved by maturation lagoons, but their reduction is significant using low doses of cumulative radiation.

“…Así, el grupo de bacterias coliformes se aplica como prueba general de monitoreo de CMA y se ha utilizado a lo largo de los últimos 100 años para llevar a cabo estudios de agua potable, contaminación de sistemas acuáticos, fuentes de contaminación de aguas residuales crudas y sistemas de tratamiento de aguas residuales y aguas recreativas (APHA, 2012). También se ha propuesto a otros microorganismos para ser usados como indicadores alternativos o bioindicadores de calidad, e. g., enterococos, Escherichia coli, entre otros (Schoen et al, 2011;Bolívar et al, 2017), y más recientemente la resurrección de Clostridium perfringers como indicador de contaminación fecal antigua (Oh et al, 2021).…”

Se realizó la calidad microbiológica del agua (CMA) de cuatro lagos cráter, Alchichica (ALCHI), Atexcac (ATx), La Preciosa (LPr) y Quechulac (QUE), de manera mensual durante un año. Se utilizaron protocolos para estimar coliformes totales (CT), coliformes fecales (CF), enterococos (ENT), E. coli, (E.coli +Rodococcus) y Clostridium perfringers. Se detectó a E. coli. en QUE, el más contaminado, seguido por ALCHI y LPr. El pH, OD y temperatura no variaron en el estudio. La salinidad fluctuó de 0 a 10.0 mgL-1. Utilizando la asociación con Rodococcus se estableció que ATx, LPr y ALCHI presentaron contaminación derivada del ganado, mientras QUE presentó contaminación fecal de origen humano. E. coli no subsiste en los Axalapascos, por lo que es alóctono al sistema y oportunista por las descargas fecales del ganado circundante debido a malas prácticas agropecuarias. Los niveles de contaminación microbiológica en los lagos cráter, superan la normatividad vigente para uso humano, agropecuario, de turismo.
